    STEPHENS, C.J.⸺After a night of drinking with friends, Kimberly Gerlach
    fell from the second-story balcony of her boyfriend’s unit at the Cove Apartments
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    when the decayed balcony railing gave way. Gerlach sued, arguing Cove’s failure
    to repair the railing caused her fall and violated Cove’s duties to tenants and their
    guests. A jury agreed and found Cove was 93 percent at fault for Gerlach’s injuries.
    The Court of Appeals overturned this verdict and remanded for a new trial, reasoning
    the trial court erred by excluding evidence of Gerlach’s blood alcohol concentration
    (BAC) and by not dismissing Gerlach’s statutory claim under the Residential
    Landlord-Tenant Act of 1973 (RLTA), ch. 59.18 RCW.
    We reverse the Court of Appeals. The trial court did not abuse its discretion
    by excluding BAC evidence that was only minimally relevant to Cove’s affirmative
    defense and risked prejudicing the jury against Gerlach. While we agree that the
    trial court should not have allowed Gerlach’s RLTA claim, this error alone does not
    justify a new trial because the jury’s verdict remains valid as to Gerlach’s common
    law claim. Accordingly, we reinstate the verdict in favor of Gerlach.
    FACTS
    One evening in October 2012, Gerlach went to a birthday party with her
    boyfriend, Nathan Miller, and their friends, Brodie and Colin Liddell.1 After the
    party, the four friends went out to a bar. When the bar closed for the night, Gerlach
    and Brodie made their way back to Miller’s unit at the Cove Apartments while Miller
    1
    Because Brodie and Colin Liddell share a surname, we use their first names for
    the sake of clarity. We intend no disrespect.
    -2-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    and Colin went to a convenience store. As Gerlach headed up toward Miller’s
    second-story apartment, Brodie stayed outside to smoke.
    A short time later, Brodie heard a sharp snap and turned to see Gerlach
    plummeting headfirst from the balcony of Miller’s apartment onto the concrete steps
    below. The decayed balcony railing fell beside her. Brodie called 911 and checked
    Gerlach’s vital signs. Miller and Colin arrived while paramedics were en route.
    The parties dispute how Gerlach fell. Gerlach argued at trial that she was
    standing on the balcony and leaning on the railing when it gave way, while Cove
    argues Gerlach likely fell while trying to climb over the railing onto the balcony.
    But no one actually saw Gerlach fall, and Gerlach herself has no recollection of that
    evening.
    Either way, Gerlach was unconscious and unresponsive when paramedics
    arrived. King County Medic One rushed her to Harborview Medical Center, where
    Gerlach was admitted with a traumatic brain injury, skull fractures, and cerebral
    hemorrhaging that required surgery. Harborview also conducted a blood test less
    than an hour after Gerlach fell, which showed her BAC was approximately 0.219.
    PROCEDURAL HISTORY
    Gerlach sued Cove Apartments for negligently causing her injuries, arguing
    Cove’s failure to repair the decayed railing violated its common law duties to tenants
    -3-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    and their guests, its duties as a landlord under the RLTA, and its duties under its
    lease agreement with Gerlach’s boyfriend. Cove moved for summary judgment on
    the second and third claims, arguing Gerlach could not prevail because she was not
    Cove’s tenant. The trial court agreed and granted summary judgment for Cove on
    Gerlach’s claim under the lease, but ruled Gerlach could recover under the RLTA
    despite not being a tenant. Gerlach’s RLTA and common law claims went to trial.
    At trial, Cove claimed the “complete defense to an action for damages for
    personal injury” available under RCW 5.40.060 when “the person injured . . . was
    [(1)] under the influence of intoxicating liquor or any drug at the time of the
    occurrence causing the injury . . . and [(2)] that such condition was a proximate cause
    of the injury . . . and [(3)] the trier of fact finds such person to have been more than
    fifty percent at fault.” RCW 5.40.060(1). To support this defense, Cove sought to
    offer into evidence the results of the blood test taken by Harborview showing
    Gerlach’s BAC was approximately 0.219, as well as expert testimony relating to
    those results. 2
    Gerlach moved to exclude the blood test results and related testimony under
    Evidentiary Rule (ER) 403, arguing the probative value of that evidence was
    2
    Extrapolating from the Harborview blood test, Cove expert witness Dr. Frank
    Vincenzi would have testified that Gerlach’s BAC would have been roughly 0.238 at the
    time she fell.
    -4-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    substantially outweighed by the danger of unfair prejudice. The trial court was
    initially inclined to admit that evidence but decided to exclude it after Gerlach
    admitted the fact of her intoxication. 3 The trial court also excluded the testimony of
    Dr. Thomas Wickizer, a health economist who would have challenged Gerlach’s
    claimed medical expenses, because his testimony would not have helped the jury to
    determine whether those expenses were reasonable.
    The jury found both Cove and Gerlach negligently contributed to Gerlach’s
    injuries, with Cove bearing 93 percent of the fault and Gerlach bearing 7 percent.
    Without objection from either party, the jury used a verdict form that did not
    distinguish between negligence premised on Cove’s common law duties and
    negligence premised on Cove’s duties under the RLTA. Cove appealed, assigning
    error to the trial court’s denial of summary judgment on Gerlach’s RLTA claims, its
    exclusion of the BAC evidence and related testimony, nearly a dozen jury
    instructions or proposed instructions, and other issues.
    The Court of Appeals reversed and remanded for a new trial. Relevant to our
    review, the Court of Appeals held the trial court abused its discretion by excluding
    the BAC evidence and related expert testimony and this error was prejudicial to
    3
    The trial court described Gerlach’s admission as a stipulation between the parties.
    Cove insists it never agreed to such a stipulation. The distinction between an admission
    and a stipulation is not relevant here, where the jury was unambiguously told Gerlach had
    been intoxicated when she fell.

    813, 817, 
    446 P.3d 624
     (2019). The Court of Appeals also concluded the trial court
    erred by denying Cove’s motion for summary judgment on Gerlach’s RLTA claims
    and by instructing the jury that Cove owed Gerlach a duty under the RLTA, because
    “Washington has adopted § 17.6 [of the Restatement (Second) of Property: Landlord
    and Tenant (Am. Law Inst. 1977)] only in cases where a landlord’s negligence is
    alleged by a tenant.” Id. at 832-33. Without further analysis, the Court of Appeals
    declined to extend Washington’s adoption of § 17.6 to tenants’ guests.

    ANALYSIS
    This case centers on two decisions made by the trial court: one about whether
    to admit evidence and one about the meaning of the RLTA. We review the
    evidentiary decision for abuse of discretion, deferring to the trial court’s judgment
    unless we are “convinced that ‘no reasonable person would take the view adopted
    by the trial court.’” Gilmore v. Jefferson County Pub. Transp. Benefit Area,

    We also granted review of issues Cove conditionally raised in its answer to the

    I. The Trial Court Did Not Abuse Its Discretion by Excluding the Results of
    Gerlach’s Hospital Blood Draw and Related Expert Testimony
    Cove argues the trial court abused its discretion by excluding from evidence
    the BAC results of Gerlach’s blood work at Harborview and related expert
    testimony, which Cove claims would have shown Gerlach’s intoxication made her
    more than 50 percent at fault for her injuries. The Court of Appeals agreed. Gerlach
    counters that the trial court acted within its discretion under ER 403 because that
    evidence would have been far more unfairly prejudicial to Gerlach than probative of
    Cove’s affirmative defense. Because the trial court’s decision was within the bounds
    of its considerable discretion, we agree with Gerlach and reverse the Court of
    Appeals.

    A. The Trial Court Appropriately Exercised Its Discretion under ER 403 To
    Exclude Minimally Probative and Speculative Evidence That Posed a
    Significant Risk of Unfair Prejudice
    Cove argues the trial court erred by excluding evidence central to its
    affirmative defense. But “[t]rial courts enjoy ‘wide discretion in balancing the
    probative value of evidence against its potentially prejudicial impact.’” Salas v.
    Hi-Tech Erectors, 
    168 Wn.2d 664
    , 671, 
    230 P.3d 583
     (2010) (quoting State v.
    Stenson, 
    132 Wn.2d 668
    , 702, 
    940 P.2d 1239
     (1997)). Even if relevant, “evidence
    may be excluded if its probative value is substantially outweighed by the danger of
    unfair prejudice.” ER 403.
    “When evidence is likely to stimulate an emotional response rather than a
    rational decision, a danger of unfair prejudice exists.” Salas, 
    168 Wn.2d at
    671
    (citing State v. Powell, 
    126 Wn.2d 244
    , 264, 
    893 P.2d 615
     (1995)). Though rare,
    the danger of unfair prejudice can exist even when the evidence at issue “is
    undeniably probative of a central issue in the case.” Carson v. Fine, 
    123 Wn.2d 206
    ,
    224, 
    867 P.2d 610
     (1994) (citing United States v. 0.161 Acres of Land, 
    837 F.2d 1036
    , 1041 (11th Cir. 1988)). Here, the trial court appropriately determined Cove’s
    proffered evidence was only minimally probative of the issues relevant to its
    affirmative defense and found the relative risk of prejudice against Gerlach was
    unacceptably high.
    -8-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    To prevail on its affirmative defense, Cove was required to prove that (1)
    Gerlach was intoxicated when she fell, (2) her intoxication was a proximate cause
    of her injury, and (3) she was more than 50 percent at fault. RCW 5.40.060(1). At
    trial, Gerlach admitted to the fact of her intoxication.5 Cove therefore needed to
    prove only causation and degree of fault to avoid liability for Gerlach’s injuries.
    Cove sought to admit the BAC results of Gerlach’s blood work at Harborview
    as foundation for the expert testimony of Dr. Frank Vincenzi and Dr. Michael
    Carhart.6 Dr. Vincenzi would have testified that “essentially everybody will be
    impaired” at the blood alcohol level Harborview’s test found in Gerlach. 2 Verbatim
    Report of Proceedings (VRP) (June 14, 2017) at 1533. In an offer of proof, Dr.

    If a plaintiff does not admit to being intoxicated, RCW 5.40.060(1) uses the same
    standard as required for criminal convictions under RCW 46.61.502. That statute provides
    two methods by which parties can prove a person was under the influence of drugs or
    alcohol. First, a party may prove that a person was under the influence per se by showing
    their BAC was 0.08 or higher through a timely blood or breath test that complies with state
    toxicology standards. RCW 46.61.502(1)(a). Second, a party may show a person is “under
    the influence of or affected by intoxicating liquor” by other evidence. RCW
    46.61.502(1)(c). By providing two different methods to prove intoxication, “the legislature
    was drawing a distinction between tests performed by the State and its agents . . . and other
    tests, such as tests done . . . for medical treatment.” City of Seattle v. Clark-Munoz, 
    152 Wn.2d 39
    , 49, 
    93 P.3d 141
     (2004). So tests done for medical purposes are admissible to
    prove intoxication under RCW 46.61.502(1)(c), but they are “subject to the usual
    evidentiary checks” as any other proffered evidence, including ER 403.

    The Court of Appeals held the trial court did not err by excluding Dr. Carhart’s
    testimony because “Dr. Carhart is not an expert in how alcohol affects the human body,
    and his testimony on this issue would have been speculative.” Gerlach, 8 Wn. App. 2d at
    827. Cove did not challenge this holding in its answer to the petition for review, so it is
    not at issue here.
    -9-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    Vincenzi opined that Gerlach’s “[p]sychomotor impairment” was “critical in this
    case” because, given her BAC results, Gerlach was probably “staggering, stumbling,
    holding on to objects for balance, falling down or lost [her] balance, and of course
    that’s in my opinion what happened here.” Id. at 1532-33.
    But in response to questions from Gerlach’s counsel, Dr. Vincenzi confirmed
    that his testimony would be about “population averages,” Id. at 1536, and that he
    could not “specifically say anything about Ms. Gerlach herself,” id. at 1540. Dr.
    Vincenzi did not know “what her burn-off ration would be for alcohol,” “what her
    absorption rate would be for alcohol,” “what her metabolic rate would be with regard
    to alcohol,” or “when at any particular time that Kim Gerlach allegedly consumed
    any alcohol on October 26 or October 27, 2012.” Id. at 1536-37. Pressed on whether
    he had “actual facts to apply to Ms. Gerlach in this matter,” Dr. Vincenzi replied that
    he “ha[d] her body weight and [had] the average volume on distribution in females
    and base my calculations on those,” but conceded “average volume in females” was
    “based upon a population average, [and] not Ms. Gerlach.” Id. at 1539.
    Gerlach moved to exclude this testimony, arguing that “an expert cannot
    testify on how an intoxicant is likely to affect an individual on any particular
    occasion” because, absent evidence that the intoxicant actually had that effect on the
    individual, such testimony would be speculative and unfairly prejudicial. Clerk’s
    -10-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    Papers (CP) at 974 (citing State v. Lewis, 
    141 Wn. App. 367
    , 387, 
    166 P.3d 786
    (2007) (holding trial court properly excluded speculative testimony from medical
    examiner on the general effects of high levels of methamphetamine, including
    causing aggressive and irrational behavior, because medical examiner could not
    speak to whether methamphetamine had those effects on the individual in question
    and there was no other evidence that it had)). The trial court agreed with Gerlach,
    explaining,
    We don’t have a very clear understanding of exactly what—of what
    occurred in this accident, except that we know that the railing failed, and we
    know that because it was on the ground along with the plaintiff and we can
    see the holes and the rot in the guardrail and that seems to be without any
    question.
    So we don't know what the plaintiff did immediately prior to the
    railing failing. We know that she—well, we now know that she had had a
    significant amount of alcohol to drink, enough to make her intoxicated at the
    time of the event.
    But whether or not that intoxication has anything at all to do with the
    actual accident, until we have something further, facts further to support that
    allegation, it’s more prejudicial than probative to allow Dr. Vincenzi to come
    in and opine how the plaintiff was acting immediately before she fell.
    1 VRP (June 15, 2017) at 1562 (emphasis added). The trial court ruled Dr. Vincenzi
    would not be allowed to testify for any purpose, including to establish “that even at
    the .08 level, [t]here are . . . impairments people have when they drink,” id. at 1563,
    because such generalized testimony would be merely “speculative,” CP at 1553.
    The trial court’s ruling is sound. The problem with “speculative testimony is
    that the trier of fact will be forced to speculate as to causation without an adequate
    -11-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    factual basis.” Volk v. DeMeerleer, 
    187 Wn.2d 241
    , 277, 
    386 P.3d 254
     (2016) (citing
    Little v. King, 
    160 Wn.2d 696
    , 705, 
    161 P.3d 345
     (2007)). Cove offered the BAC
    results and Dr. Vincenzi’s testimony to prove Gerlach’s intoxication was a
    proximate cause of her injuries and that she was more than 50 percent at fault. But
    like the medical examiner in Lewis, Dr. Vincenzi’s proffered testimony was merely
    speculative as to Gerlach’s behavior. He was going to speak to the general effects
    of intoxication, not the effect it actually had on Gerlach. Dr. Vincenzi acknowledged
    he could not speak to whether Gerlach experienced or acted on such effects, so his
    testimony would not have helped the jury determine whether Gerlach’s actions
    caused her injuries or increased her degree of fault. “Such speculative testimony is
    not rendered less speculative or of more consequence to the jury’s determination
    simply because it comes from an expert.”           Lewis, 141 Wn. App. at 389.
    Dr. Vincenzi’s testimony would have been only minimally probative of causation
    and fault because he could not link Gerlach’s intoxication to any actual behavior
    leading to her fall. 2 VRP (June 14, 2017) at 1540.
    Worse, Dr. Vincenzi’s testimony about the general effects of high levels of
    intoxication risked prejudicing the jury against Gerlach because it was “likely to
    stimulate an emotional response rather than a rational decision.” Salas, 
    168 Wn.2d at 671
    . In his offer of proof, Dr. Vincenzi indicated his testimony essentially would
    -12-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    have been that Gerlach was so drunk she must have been impaired and making risky
    decisions. As Gerlach’s counsel cautioned the trial court, “a blood alcohol [level]
    three times the limit [is] going to be really hard for a jury to get out of their brains”—
    at that point, “the bell’s been rung.” 1 VRP (June 15, 2017) at 1555-56.7 That risk
    is exacerbated where a medical doctor speculates about the impact such a blood
    alcohol level may have had on Gerlach without any regard to her actual behavior.
    Excluding such speculative, minimally probative evidence and testimony as too
    unfairly prejudicial to Gerlach was well within the trial court’s discretion under ER
    403.8
    B. The Court of Appeals Erred by Suggesting Higher Blood Alcohol Level
    Alone Is Relevant to an Intoxicated Plaintiff’s Fault and Causation
    Misreading our decision in Peralta v. State, 
    187 Wn.2d 888
    , 
    389 P.3d 596
    (2017), the Court of Appeals wrongly suggested that high BAC levels alone could
    be evidence of a plaintiff’s heightened degree of fault or causation. Gerlach, 8 Wn.
    App. 2d at 824 (holding “the trial court abused its discretion in excluding the
    7
    The Court of Appeals agreed that “Gerlach’s high blood alcohol level could
    stimulate an emotional response in a jury,” but believed it had high enough probative value
    that the trial court abused its discretion by excluding it. Gerlach, 8 Wn. App. 2d at 821.
    8
    Cove also challenges the trial court’s exclusion of Dr. Wickizer’s expert testimony,
    which would have compared Gerlach’s medical expenses to Medicare reimbursement rates.
    The Court of Appeals upheld that exclusion because “[e]vidence that, on average, a
    procedure costs less than the amount charged or that Gerlach’s physicians accept a lesser
    payment for services from Medicare is not helpful to the jury in determining whether her
    medical expenses were reasonable.” Id. at 829. We agree and find no error.
    -13-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    evidence of Gerlach’s blood alcohol level at the time of the accident and the
    exclusion prejudiced Cove’s ability to prove its affirmative defense”). The Court of
    Appeals here determined Peralta did not support the trial court’s decision to exclude
    evidence in this case because our Peralta opinion noted that the State “offered
    substantial evidence supporting its intoxication defense” even after the plaintiff
    admitted she was intoxicated, Peralta, 187 Wn.2d at 900 n.6, while “the exclusion
    of Gerlach’s blood alcohol evidence resulted in a complete absence of evidence as
    to the extent of her intoxication,” Gerlach, 8 Wn. App. 2d at 822. This reasoning is
    flawed in three ways.
    First, the Court of Appeals erred by failing to examine the facts in Peralta to
    understand why the State had been able to offer evidence of the plaintiff’s
    intoxication even after her admission. Unlike Gerlach, the plaintiff in Peralta argued
    she was not bound by her admission that she was intoxicated, so the State was able
    to offer additional evidence of her intoxication in case the trial court allowed the
    plaintiff to retract or alter her admission. See Peralta v. State, 
    191 Wn. App. 931
    ,
    944, 
    366 P.3d 45
     (2015) (“Peralta argues that the trial court erred when it ruled that
    her response to the request for admission that she was ‘under the influence of
    intoxicating liquors’ constituted an admission that Peralta was under the influence
    for purposes of RCW 5.40.060(1).”). Our decision in Peralta does not support
    -14-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    allowing additional evidence of the plaintiff’s intoxication beyond her admission;
    instead, that decision turned on whether the trial court appropriately instructed the
    jury that she was bound by that admission.
    The Court of Appeals also erred by suggesting Gerlach’s BAC results alone
    could determine her degree of fault. Gerlach admitted the fact of her intoxication—
    establishing the first prong of Cove’s affirmative defense—so the BAC evidence
    would need to relate to the second and third prongs to be admissible. See RCW
    5.40.060(1). But the BAC results are not relevant to questions of causation and fault
    because these questions turn on evidence of a plaintiff’s behavior, not intoxication
    status. While being intoxicated can certainly influence a person’s behavior, the fact
    of intoxication does not prove a person was acting in any particular way. Whether
    and to what degree a person is at fault depends on how that person acted or failed to
    act, not their precise degree of intoxication. As noted, the trial court properly
    concluded that Dr. Vincenzi’s testimony about blood alcohol levels was speculative
    as to Gerlach’s behavior. See 1 VRP (June 15, 2017) at 1562 (“[W]hether or not
    [Gerlach’s] intoxication has anything at all to do with the actual accident, until we
    have something further, facts further to support that allegation, it’s more prejudicial
    than probative to allow Dr. Vincenzi to come in and opine how the plaintiff was
    acting immediately before she fell.”). Here, without other evidence or testimony
    -15-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    that could connect Gerlach’s BAC results to behavior that caused her fall, the BAC
    results were not relevant to whether her intoxication was a proximate cause of her
    injuries or to her degree of fault.
    The Court of Appeals further erred by concluding the “lack of [other] evidence
    of Gerlach’s degree of intoxication prejudiced Cove’s ability to prove its affirmative
    defense.” Gerlach, 8 Wn. App. 2d at 823. The Court of Appeals accurately noted
    that “[n]one of Gerlach’s companions testified as to how many drinks Gerlach
    consumed that night or that she was extremely intoxicated.” 
    Id.
     But Cove, not
    Gerlach, bears the burden of submitting evidence sufficient to prove its affirmative
    defense. See Olpinski v. Clement, 
    73 Wn.2d 944
    , 950, 
    442 P.2d 260
     (1968)
    (“Defendant has the burden of proof on the issues of his affirmative defense.”). The
    fact that Cove did not have other evidence sufficient to prove its affirmative defense
    does not show the trial court abused its discretion by excluding the BAC results. All
    it shows is that Cove lacked sufficient evidence to prove the second and third prongs
    of its affirmative defense.
    For these reasons, the Court of Appeals was wrong to overturn the trial court’s
    discretionary decision to exclude prejudicial evidence of Gerlach’s blood alcohol
    level and related expert testimony. Because this was the ground on which the Court
    of Appeals overturned the jury’s verdict, we reverse and reinstate the verdict in favor
    -16-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    of Gerlach. We next consider the two bases for the jury’s verdict: the RLTA and
    landlords’ common law duties to tenants’ guests.
    II. The RLTA Does Not Support a Cause of Action for Personal Injury By the
    Guest of a Tenant, but the Common Law Does
    The legislature enacted the RLTA, ch. 59.18 RCW, to govern the rights,
    responsibilities, and remedies of residential landlords and tenants. Faciszewski v.
    Brown, 
    187 Wn.2d 308
    , 314, 
    386 P.3d 711
     (2016). The RLTA requires tenants to
    pay rent on time, keep their units clean, properly dispose of all waste, restore the
    premises to their original condition when moving out, and more. RCW 59.18.130.
    The act requires landlords to “keep the premises fit for human habitation” by
    fulfilling particular duties, including by maintaining “the structural components” of
    the dwelling unit “in reasonably good repair so as to be usable.” RCW 59.18.060.
    Gerlach alleged that by failing to repair the decayed railing, Cove violated its
    duties as a landlord under the RLTA and negligently caused her injuries. Cove
    moved for summary judgment on Gerlach’s RLTA claims on the ground that, as a
    tenant’s guest, she is not protected by the act. The trial court denied Cove’s motion
    and later instructed the jury that a landlord can be liable to a tenant’s guest for
    violating the RLTA. We review questions of law, including the legal accuracy of
    jury instructions, de novo. Joyce v. Dep’t of Corr., 
    155 Wn.2d 306
    , 323, 
    119 P.3d 825
     (2005).
    -17-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    This court has never decided whether or to what extent landlords are liable in
    tort for violations of their duties under the RLTA. But the Court of Appeals has
    issued a series of decisions adopting a section of the Restatement and holding that
    “tenant[s have] a remedy, supported by public policy, through which he or she may
    recover for injuries caused by the landlord’s breach of the RLTA.” Lian v. Stalick,
    
    106 Wn. App. 811
    , 822, 
    25 P.3d 467
     (2001) (Lian I); see also Lian v. Stalick, 
    115 Wn. App. 590
    , 
    62 P.3d 933
     (2003) (Lian II); Tucker v. Hayford, 
    118 Wn. App. 246
    ,
    
    75 P.3d 980
     (2003); Martini v. Post, 
    178 Wn. App. 153
    , 
    313 P.3d 473
     (2013);
    Phillips v. Greco, 7 Wn. App. 2d 1, 
    433 P.3d 509
     (2018).
    Restatement § 17.6 provides:
    A landlord is subject to liability for physical harm caused to the tenant
    and others upon the leased property with the consent of the tenant or his
    subtenant by a dangerous condition existing before or arising after the tenant
    has taken possession, if he has failed to exercise reasonable care to repair the
    condition and the existence of the condition is in violation of:
    (1) an implied warranty of habitability; or
    (2) a duty created by statute or administrative regulation.
    In Lian I, Division Three of the Court of Appeals “recognized a cause of
    action for the implied warranty of habitability under the [RLTA] according to
    subpart (1) of the Restatement.” Tucker, 118 Wn. App. at 256 (citing Lian I, 106
    Wn. App. at 822). In Tucker, Division Three recognized a cause of action for tenants
    under the second subsection of the Restatement. Id. at 257-58 (“We conclude that
    the Washington Residential Landlord-Tenant Act of 1973 provides a cause of action
    -18-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    for the injury sustained [by the tenant] here.”). Division Two soon followed suit.
    See Martini, 178 Wn. App. at 170-71 (holding § 17.6 “appl[ies] to injuries suffered
    by a tenant due to a landlord’s breach of the implied warranty of habitability or a
    breach of a duty specified by statute or regulation” (citing Lian I, 
    106 Wn. App. 811
    )).
    Here, Division One ruled that the trial court erred because “Washington has
    only adopted § 17.6 in cases where a landlord’s negligence is alleged by a tenant”
    and that “section has not been adopted in the context of claims by nontenants.”
    Gerlach, 8 Wn. App. 2d at 832-33 (citing Phillips, 7 Wn. App. 2d at 6-7). This is
    an accurate description based on the nature of the claims in the prior cases, but the
    Court of Appeals did not conduct any further analysis as to whether the Restatement
    section extends a duty to tenants’ guests, including Gerlach.
    Determining the reach of a landlord’s liability under the Restatement requires
    closer examination of the existing precedent. The series of Court of Appeals cases
    addressing the section inappropriately conflate the common law implied warranty of
    habitability with a landlord’s statutory duties under the RLTA requiring the landlord
    to “keep the premises fit for human habitation.” RCW 59.18.060. See Tucker, 118
    Wn. App. at 256 (recognizing “a cause of action for the implied warranty of
    habitability under the Landlord-Tenant Act according to subpart (1) of the
    -19-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    Restatement.” (citing Lian I, 106 Wn. App. at 822)). Although the RLTA does
    require landlords to maintain basic standards of habitability, we have never held that
    that statutory language creates a warranty, much less that it subsumes the common
    law warranty of habitability. Rather, our cases have maintained a distinction
    between the duties imposed by the RLTA and the common law implied warranty of
    habitability. See Foisy v. Wyman, 
    83 Wn.2d 22
    , 28-29, 
    515 P.2d 160
     (1973)
    (recognizing implied warranty of habitability distinct from the RLTA, which the
    legislature passed between the filing and resolution of the case); see also Landis &
    Landis Constr., LLC v. Nation, 
    171 Wn. App. 157
    , 163, 
    286 P.3d 979
     (2012) (“The
    implied warranty of habitability recognized in Foisy is available to a tenant as a basis
    for legal action against a landlord under the common law, independent of the
    Residential Landlord-Tenant Act.”). Because the implied warranty of habitability is
    independent of the RLTA, the Court of Appeals was wrong to conflate the two in
    the series of decisions partially adopting § 17.6.
    The Court of Appeals here also erred by not sufficiently inquiring as to why
    Washington law would not support the extension of § 17.6 to nontenants like
    Gerlach. A number of Washington cases support the proposition that a landlord
    owes the same duty to a tenant’s guest or employee as the landlord owes to the
    tenant. See, e.g., Regan v. City of Seattle, 
    76 Wn.2d 501
    , 505, 
    458 P.2d 12
     (1969)
    -20-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    (holding landlord is liable “‘to his tenant or the tenant’s guest’” for a negligent repair
    (quoting Rossiter v. Moore, 
    59 Wn.2d 722
    , 725, 
    370 P.2d 250
     (1962))). The Court
    of Appeals did not adequately address why these cases do not support the full
    adoption of § 17.6, which states a “landlord is subject to liability for physical harm
    caused to the tenant and others upon the leased property with the consent of the
    tenant.” RESTATEMENT § 17.6 (emphasis added).
    We take this opportunity to clarify Washington law by recognizing a cause of
    action for tenants and their guests for personal injuries caused by a landlord’s
    violation of the common law warranty of habitability, but not under the RLTA. 9
    A. Washington Law Supports Partially Adopting Restatement § 17.6 by
    Recognizing a Cause of Action for Violation of the Implied Warranty of
    Habitability as to Both Tenants and Their Guests
    In its early years, Washington’s landlord-tenant law embraced the doctrine of
    caveat emptor: “let the buyer beware.” BLACK’S LAW DICTIONARY 276 (11th ed.
    2019). This doctrine provides that a tenant rents property at their own risk, so the
    landlord cannot be liable for any injuries the tenant suffers for having taken that risk.
    As we explained in Teglo v. Porter:
    It is the general rule, as between landlord and tenant, that, absent
    agreement to the contrary or a fraudulent concealment of obscure defects, the
    9
    Gerlach’s unchallenged common law claims were based on premises liability, not
    the implied warranty of habitability. But because Washington courts’ treatment of
    Restatement § 17.6 has conflated the common law implied warranty of habitability with
    the RLTA, we disentangle and explain both here.
    -21-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    maxim caveat emptor applies, and the tenant takes the demised premises as
    he finds them. There is no implied warranty or covenant on the landlord’s
    part that the premises are safe or fit for the purpose intended.
    
    65 Wn.2d 772
    , 773, 
    399 P.2d 519
     (1965) (citing Hughes v. Chehalis School Dist.
    No. 302, 
    61 Wn.2d 222
    , 
    377 P.2d 642
     (1963)).
    The doctrine of caveat emptor was “formulated at a time when the economy
    was primarily agrarian.” RESTATEMENT § 5.1 cmt. b. It “was based on the premise
    that the tenant had ample opportunity to inspect the leased property” for defects and
    that any such defects “were generally reparable by hand by the tenant himself.” Id.
    But “the modern residential tenant is severely injured by such a rule.” Id. The
    “complexities of construction” in modern homes and apartments mean that most
    tenants cannot “conduct an inspection of sufficient depth to discover even major
    defects.” Id. And even “when hidden defects become known, they are seldom
    within the ability of the tenant to repair. Id.
    We recognized this new reality in Foisy, 
    83 Wn.2d at 28
    . There, a tenant
    argued his landlord’s failure to repair a number of defects—“including a lack of heat,
    no hot water tank, broken windows, a broken door, water running through the
    bedroom, an improperly seated and leaking toilet, a leaking sink in the bathroom,
    broken water pipes in the yard and termites in the basement”—relieved the tenant of
    his obligation to pay rent. 
    Id. at 24-25
    . We agreed, noting,
    -22-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    “When American city dwellers, both rich and poor, seek ‘shelter’ today, they
    seek a well known package of goods and services—a package which includes
    not merely walls and ceilings, but also adequate heat, light and ventilation,
    serviceable plumbing facilities, secure windows and doors, proper sanitation,
    and proper maintenance.”
    
    Id. at 27
     (quoting Javins v. First Nat’l Realty Corp., 
    138 U.S. App. D.C. 369
    , 
    428 F.2d 1071
    , 1074 (1970)). We reasoned there was “little justification for following a
    rule that was developed for an agrarian society and has failed to keep pace with
    modern day realities.” Id. at 28. We concluded “the old rule of caveat emptor has
    little relevance to the renting of premises in our society” and held “that in all
    contracts for the renting of premises, oral or written, there is an implied warranty of
    habitability.” 10 Id.
    By recognizing an implied warranty of habitability for residential rental
    property and abandoning caveat emptor in this area, “we discarded the very legal
    foundation and justification for the landlord’s immunity in tort for injuries to the
    tenant or third persons.” Sargent v. Ross, 
    113 N.H. 388
    , 397, 
    308 A.2d 528
    , 533-34
    (1973). Absent such immunity, whether a landlord is liable to a tenant’s guest for
    10
    Washington is not alone in abandoning caveat emptor in favor of recognizing an
    implied warranty of habitability for residential rental property. See, e.g., Young v.
    Garwacki, 
    380 Mass. 162
    , 168, 
    402 N.E.2d 1045
    , 1049 (1980) (“In the line of cases
    creating and applying the implied warranty of habitability, we have overthrown the
    doctrine of caveat emptor.” (citing Berman & Sons, Inc. v. Jefferson, 
    379 Mass. 196
    , 
    396 N.E.2d 981
     (1979))).
    -23-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    injuries caused by the landlord’s breach of the implied warranty of habitability is a
    straightforward question of common law negligence.
    We have long held that landlords owe the same common law duties to tenants
    and their guests. See, e.g., Regan, 
    76 Wn.2d at 505
     (holding landlord is liable “‘to
    his tenant or the tenant’s guest’” for a negligent repair (quoting Rossiter, 
    59 Wn.2d at 725
    )); Flannery v. Nelson, 
    59 Wn.2d 120
    , 123, 
    366 P.2d 329
     (1961) (holding
    landlord liable to employee of tenant for hidden defect); Andrews v. McCutcheon,
    
    17 Wn.2d 340
    , 345, 
    135 P.2d 459
     (1943) (landlord has duty to maintain premises
    reserved under its control in a safe condition for use by “tenants and their invitees”);
    McCourtie v. Bayton, 
    159 Wash. 418
    , 423-24, 
    294 P. 238
     (1930) (recognizing “the
    guest, servant, etc., of the tenant is usually held to be so identified with the tenant
    that his right of recovery for injury as against the landlord is neither more nor less
    than that of the tenant would be”).
    Our decision in Foisy recognizing landlords’ common law duties under the
    implied warranty of habitability is entirely consistent with this jurisprudential trend.
    There, we observed that housing conditions that violate the implied warranty of
    habitability “are a health hazard, not only to the individual tenant, but to the
    community which is exposed to said individual.” 
    83 Wn.2d at 28
    . That community
    includes the tenant’s guests, who may be exposed to health hazards presented by a
    -24-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    dangerous condition on the leased premises in violation of the implied warranty of
    habitability. Consistent with the reasoning in Foisy, we adopt Restatement § 17.6 to
    the extent that we recognize a landlord’s liability in tort to tenants and their guests
    for breach of the implied warranty of habitability.
    B. The RLTA Does Not Imply a Cause of Action for Tenants’ Guests, So
    We Decline To Adopt the Remainder of Restatement § 17.6
    In addition to recognizing tort claims for breach of the implied warranty of
    habitability in subsection (1), Restatement § 17.6 subsection (2) outlines a cause of
    action in tort for injuries tenants or their guests sustain as a result of the landlord’s
    breach of specific statutory (or regulatory) duties. As the Restatement observes,
    “[T]ort liability of the landlord in this situation tends to increase the likelihood that
    the will of the legislature as expressed in the statute or regulation with be
    effectuated.” RESTATEMENT § 17.6 cmt. a. Allowing tenants to sue their landlords
    for personal injuries sustained as a result of the landlord’s breach of their duties
    would provide a powerful incentive for landlords to fulfill their statutory duties. See
    RESTATEMENT § 17.6 reporter’s note 8 (noting “it will be difficult to insulate the
    landlord from tort liability when his failure to meet his duty results in injury to the
    tenant”). And “[i]t would be disconcerting if the tenant who fell through the rotten
    floor of his kitchen could withhold rent until the hole was repaired, but could not
    recover for the personal injury he had sustained.” Id. But the liability theory the
    -25-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    Restatement recognizes in this subsection originated in a theory of negligence per se
    that Washington has largely abandoned. Compare RESTATEMENT § 17.6 cmt. a
    (suggesting violation of a landlord’s statutory duty is sufficient to establish landlord
    liability in tort because “the violation constitutes negligence per se”), with RCW
    5.40.050 (“A breach of a duty imposed by statute, ordinance, or administrative rule
    shall not be considered negligence per se, but may be considered by the trier of fact
    as evidence of negligence.”).
    Rather than adopt the second part of the Restatement unquestioningly, we
    apply our usual test to determine the existence and scope of an implied cause of
    action arising from statute. See Bennett v. Hardy, 
    113 Wn.2d 912
    , 
    784 P.2d 1258
    (1990). In Bennett, we established a three-part test to determine whether a statute
    supports an implied cause of action:
    [F]irst, whether the plaintiff is within the class for whose “especial” benefit
    the statute was enacted; second, whether legislative intent, explicitly or
    implicitly, supports creating or denying a remedy; and third, whether
    implying a remedy is consistent with the underlying purpose of the
    legislation.
    Id. at 920-21. Here, the first factor is dispositive as to Gerlach’s RLTA claim.
    The legislature did not enact RLTA for the benefit of tenants’ guests but,
    rather, to regulate the legal relationships between landlords and tenants. The RLTA
    mentions tenants’ guests or invitees only in the context of a tenant’s duties to ensure
    their family and friends do not damage the unit, violate the law, or otherwise
    -26-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    compromise the terms of their lease. See, e.g., RCW 59.18.130(4) (imposing duty
    on tenant to not “permit any member of his or her family, invitee, licensee, or any
    person acting under his or her control” to “intentionally or negligently destroy,
    deface, damage, impair, or remove any part of the structure or dwelling”),
    .550(1)(d)(ii) (“The tenant may not allow the guests to use, possess, or share alcohol,
    illegal drugs, controlled substances, or prescription drugs without a medical
    prescription, either on or off the premises”), .060(15) (providing no “defense or
    remedy [is] available to the tenant under this chapter, where the defective condition
    complained of was caused by the conduct of such tenant, his or her family, invitee,
    or other person acting under his or her control”). No RLTA provisions speak to a
    landlord’s obligations to a tenant’s guest. Gerlach, as a guest of Cove’s tenant, is
    therefore not within the class for whose benefit the legislature enacted the RLTA.
    Because the first Bennett factor is dispositive, we need not address the remaining
    factors to decide the RLTA does not support an implied cause of action for tenants’
    guests. Accordingly, the trial court erred by allowing the jury to consider Gerlach’s
    claim under this theory of liability.
    -27-
    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    III. Though the Trial Court Erred by Allowing Gerlach’s RLTA Claim To
    Proceed, the Jury’s Verdict Rests on a Valid Common Law Liability Theory
    and Cove Failed To Object to the Undifferentiated Verdict Form
    As noted above, the jury in this case used a verdict form that did not
    distinguish between negligence premised on Cove’s common law duties and
    negligence premised on Cove’s duties under the RLTA. A party challenging the
    validity of one theory supporting an undifferentiated verdict is not entitled to a new
    trial unless it objected to the use of the verdict form at trial and proposed a special
    verdict form to clarify the jury’s findings. Davis v. Microsoft Corp., 
    149 Wn.2d 521
    ,
    539-40, 
    70 P.3d 126
     (2003). Cove failed to do so here and therefore is not entitled
    to a new trial on this ground.
    CONCLUSION
    The trial court did not abuse its discretion by excluding evidence that would
    have been speculative, prejudicial, and only minimally probative of Cove’s
    affirmative defense. While the trial court did err by allowing the jury to consider
    Gerlach’s claim based on Cove’s alleged breaches of the RLTA, that error is not a
    basis to invalidate the jury’s undifferentiated verdict, which also rests on common
    law negligence. Accordingly, we reverse the Court of Appeals and reinstate the
    verdict in favor of Gerlach.

    Gerlach v. The Cove Apartments, LLC, et al., 97325-3
    WE CONCUR:
    -29-
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    No. 97325-3
    GORDON McCLOUD, J. (concurring in part/dissenting in part)—In this
    case, the plaintiff’s intoxication and the effects of that intoxication on her mattered
    tremendously. If the jury had found that Kimberly Gerlach’s intoxication
    proximately caused her injuries and that she was more than 50 percent at fault, then
    a duly enacted statute would have barred her from collecting money damages for
    her injuries. RCW 5.40.060(1). Yet the trial court excluded the most probative
    piece of evidence about her intoxication: her extremely high blood alcohol
    concentration (BAC). The trial court also barred an expert witness from testifying
    about the effects of such a high BAC. This constitutes an abuse of discretion; I
    would therefore affirm the Court of Appeals’ decision to reverse.
    Separately, I agree with the majority that Gerlach may not recover under the
    Residential Landlord-Tenant Act of 1973 (RLTA), ch. 59.18 RCW, and I join that
    portion of the majority’s opinion. I do not, however, join the majority’s extended

    analysis of the implied warranty of habitability; that analysis is pure dicta. I
    therefore respectfully concur in part and dissent in part.
    FACTS
    After a night of heavy drinking, Gerlach fell from the second-story balcony
    of her then-boyfriend’s apartment. The railing of the balcony fell with her.
    Nobody saw exactly what happened, and Gerlach does not remember the fall. At
    trial, the parties presented the jury with two opposing theories.
    Gerlach argued that she entered her boyfriend’s apartment, went out onto the
    balcony, and leaned against the railing—which snapped and sent her plummeting
    to the ground. 1 Verbatim Report of Proceedings (VRP) (July 10, 2017) at 3569-
    75. According to this theory, alcohol had nothing to do with the fall, and Gerlach
    was not at fault.
    Cove Apartments, on the other hand, argued that Gerlach never made it
    inside the apartment. Instead, Gerlach fell while attempting to climb over the
    second-story balcony’s railing and onto the balcony, from the outside. 
    Id.
     at 3620-
    24. According to Cove, Gerlach made the poor decision to climb because she was
    extremely drunk, and she was unable to successfully scale the balcony for the same
    reason. Id. at 3638-43. According to this theory, alcohol played a major role in
    the accident, and Gerlach was at fault.
    2

    (Gordon McCloud, J., concurring in part/dissenting in part)
    As mentioned above, intoxication can be a “complete defense to an action
    for damages for personal injury.” RCW 5.40.060(1). To succeed on this defense,
    Cove had to prove that (1) Gerlach “was under the influence of intoxicating liquor”
    at the time of the accident, (2) the intoxication “was a proximate cause of the
    injury,” and (3) she was more than 50 percent at fault. Id. This statutory defense
    reflects a legislative determination that “[w]hen the intoxicated party is at fault for
    a majority of his or her injuries, . . . the intoxicated party is responsible for the
    entire amount of damages.” Estate of Kelly v. Falin, 
    127 Wn.2d 31
    , 49, 
    896 P.2d 1245
     (1995).
    Thus, whether Gerlach was intoxicated and how that intoxication affected
    her ability to function were major issues for trial. Cove had evidence that Gerlach
    was not simply intoxicated, but was severely intoxicated. A blood draw performed
    at the hospital after the accident revealed that Gerlach’s BAC at the time of the fall
    was 0.238, or “essentially three times the legal limit for operation of a motor
    vehicle.” Clerk’s Papers (CP) at 511. Dr. Frank F. Vincenzi, an emeritus
    professor of pharmacology at the University of Washington, estimated that based
    on this BAC, Gerlach had consumed around 14 drinks on the night of the accident
    and had approximately “9 drinks[’] worth of alcohol present in her body at the time
    of the incident.” 
    Id.
     As a result of this calculation, Dr. Vincenzi opined that
    3
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    “alcohol-induced impairment of both judgment and psychomotor function were
    proximate causes of the tragic outcome.” 
    Id.
     His conclusion, if accepted by the
    jury, would have satisfied the first two prongs of Cove’s statutory defense: (1) that
    Gerlach was intoxicated at the time of the accident and (2) that the intoxication
    “was a proximate cause of the injury.” RCW 5.40.060(1). And it would have
    allowed the jury to evaluate the third element, whether Gerlach was more than 50
    percent at fault. 
    Id.
    But the trial court barred that evidence from ever reaching the jury,
    thwarting Cove’s ability to prove its statutory defense. I believe this was error, and
    I would affirm the Court of Appeals on this point.
    Separately, I concur in the majority’s interpretation of the RLTA. But I
    decline to endorse the majority’s dicta regarding the implied warranty of
    habitability. Thus, I respectfully concur in part and dissent in part.

    Of course, evidence of Gerlach’s severe intoxication would have prejudiced

    )). Rather,
    evidence of her intoxication went to the heart of Cove’s statutory defense. That
    evidence was undeniably probative of central issues in this case: whether she was
    intoxicated, how intoxicated she was and hence how likely it was that her
    intoxication was a proximate cause of her injuries, and whether she was more than
    50 percent at fault. Accordingly, the likelihood that ER 403 balancing would favor
    exclusion of this exceedingly probative evidence was “‘quite slim.’” Id. at 224

    6
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    Nevertheless, the trial court excluded the evidence. A review of the record
    shows that the trial court based its ruling on an erroneous view of the law. Thus,
    the trial court “necessarily abuse[d] its discretion.” Wash. State Physicians Ins.
    Exch. & Ass’n, 
    122 Wn.2d at
    339 (citing Cooter & Gell, 
    496 U.S. at 405
    ).
    A. The trial court wrongly believed that Gerlach’s intoxication was
    relevant only to the first element of Cove’s defense
    Despite expert testimony to the contrary, the trial court failed to appreciate
    that Gerlach’s severe intoxication could have proximately caused her injuries. For
    instance, the court initially rejected Dr. Vincenzi’s conclusion that Gerlach’s
    extreme intoxication had anything to do with her alleged decision to climb over the
    balcony or her inability to do so successfully, reasoning that “whether she was
    drinking or not drinking, if she climbed on the outside of the apartment and fell,
    then she’s contributorily negligent and I don’t know that the presence of alcohol
    has anything to do with that physical fact.” VRP (Apr. 7, 2017) at 56. The court
    then instructed the parties to separate the issue of Gerlach’s intoxication from the
    issue of her contributory negligence: “There’s two issues here. There’s a
    consumption of alcohol on the part of the plaintiff and there’s a contributory
    negligence, and I’d like to separate them, because I think they should be
    separated . . . .” VRP (May 5, 2017) at 102. Of course, Cove’s entire argument,
    supported by Dr. Vincenzi’s expert opinion, was that Gerlach made the negligent
    7
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    decision to climb and was unable to do so because she was intoxicated. Gerlach’s
    intoxication and alleged negligence were intertwined and inseparable.
    After additional argument, the trial court seemed to reverse course, ruling
    that Gerlach’s BAC reading was admissible. 1 VRP (June 14, 2017) at 1333. The
    court correctly reasoned that it was up to the jury to decide whether the amount of
    alcohol Gerlach consumed was a proximate cause of her injury. 
    Id.
    Still determined to keep out the BAC reading, Gerlach offered the trial court
    a compromise: she would simply admit to being intoxicated, and the trial court
    would exclude the reading. Id. at 1355. Gerlach argued that her offer to
    compromise would settle the first element of Cove’s statutory defense (that she
    was intoxicated) and “would eliminate the undue prejudice of the blood alcohol
    reading.” Id. Over Cove’s objection, the trial court agreed and excluded the BAC
    reading, along with Dr. Vincenzi’s testimony. 1 VRP (June 15, 2017) at 1560. 1
    But Gerlach’s intoxication was relevant to Cove’s entire statutory defense,
    not merely the first element of it. In addition to proving that Gerlach was
    1
    Despite Cove’s objection, the trial court told the jury that “[t]he parties stipulate
    that the plaintiff, Ms. Gerlach, was under the influence of intoxicating liquor at the time
    of the accident.” 1 VRP (June 22, 2017) at 2799-800. After initially agreeing to correct
    that misstatement, VRP (June 27, 2017) at 2948, the trial court backtracked, saying that it
    did not want to “overemphasize[ ]” Gerlach’s intoxication, 1 VRP (July 7, 2017) at 3362-
    63. The court further stated that it did not “really think the jury cares” and that in any
    event, “what [the jury] heard was that she admits that she was under the influence.” Id.
    The majority endorses this view. Majority at 5 n.3.
    8
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    intoxicated, Cove also had to prove that her intoxication was a proximate cause of
    her injury and that she was more than 50 percent at fault. RCW 5.40.060(1). As to
    these two elements, the degree of intoxication matters. The jury could have
    concluded that someone who was intoxicated, but not severely so, would have
    made different decisions and functioned differently than Gerlach, who, according
    to Dr. Vincenzi, had approximately “9 drinks[’] worth of alcohol present in her
    body” and a BAC “essentially three times the legal limit for operation of a motor
    vehicle.” CP at 511. But the court excluded all evidence on this point,
    impermissibly hindering Cove’s ability to prove the bulk of its statutory defense
    and stripping the jury of its fact-finding role.
    As discussed next, the trial court based its ultimate decision on an erroneous
    view of our precedent.
    B. The trial court misapplied precedent from our court
    The trial court read State v. Peralta, 
    187 Wn.2d 888
    , 
    389 P.3d 596
     (2017),
    as compelling the conclusion that Gerlach’s BAC was relevant only on the first
    element of the intoxication defense. 1 VRP (June 15, 2017) at 1561. But Peralta
    does not say that. In Peralta, the plaintiff admitted during pretrial discovery that
    she was intoxicated. 187 Wn.2d at 891. Later, the plaintiff argued that her
    9
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    admission did not prove the first element of the intoxication defense. Id. at 893.
    The trial court held that it did, and we affirmed. Id. at 904-05.
    Thus, all that Peralta stands for is that an admission may satisfy the first
    element of the intoxication defense. The majority states that “[o]ur decision in
    Peralta does not support allowing additional evidence of the plaintiff’s
    intoxication beyond her admission.” Majority at 15. But neither does it support
    barring additional evidence of the plaintiff’s intoxication beyond her admission.
    Nor does it suggest that an admission is relevant only as to the first element. The
    majority is correct that Peralta “turned on whether the trial court appropriately
    instructed the jury that she was bound by [her] admission.” Majority at 15. That
    was all that was at issue in that case, and we did not resolve any other issue that
    might shine light on the issues in this case. Simply put, Peralta is irrelevant, and
    the trial court was wrong to rely on it.
    Geschwind, on the other hand, is on point. That case illustrates that
    evidence of a plaintiff’s intoxication is not limited to the first element of the
    defense but instead informs the other elements, also. In that case, Geschwind sued
    Flanagan for injuries sustained in a car accident. Geschwind, 
    121 Wn.2d at 835
    .
    After a night of drinking, Geschwind and Flanagan decided to drive home. 
    Id. at 836
    . Although Flanagan, the driver, hit two cars while pulling out of his parking
    10
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    space, Geschwind decided to remain in the truck. 
    Id.
     Flanagan proceeded to drive
    off the road and into a pole. 
    Id.
     Notably, the plaintiff’s BAC was part of the
    record. 
    Id.
    Geschwind sued Flanagan. 
    Id. at 835
    . Flanagan, the driver, relied on the
    statutory intoxication defense to argue that Geschwind, the passenger, was
    primarily at fault. 
    Id.
     The jury agreed, and Geschwind was denied recovery. 
    Id.
    Geschwind appealed, arguing that a passenger, though negligent, could never be
    more at fault than the driver who caused the accident. 
    Id.
    We rejected that argument. 
    Id. at 839
    . We reasoned that a jury could have
    determined that Geschwind made the decision to ride with a drunk driver because
    he himself was intoxicated, and that his decision was the main cause of his injuries.
    
    Id. at 841-42
    ; see also former RCW 5.40.060 (1992) (providing “a complete
    defense” if plaintiff’s intoxication “was a proximate cause of the injury”).2 “‘The
    rationale for this rule is that intoxication diminishes a passenger’s appreciation of
    danger and renders the passenger more likely to take greater risks than usual.’”
    2
    This statute has since been amended. SUBSTITUTE S.B. 6047, at 43, 53d Leg.,
    Reg. Sess. (Wash. 1994). Today, in actions against drunk drivers, the plaintiff’s
    intoxication must have been “a proximate cause of the occurrence causing the injury or
    death,” not simply the injury itself. RCW 5.40.060(2) (emphasis added). Because this
    change was limited to actions against drunk drivers, it does not affect the case before us.
    11
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    Geschwind, 
    121 Wn.2d at 842
     (quoting WASH. STATE BAR ASS’N, WASHINGTON
    MOTOR VEHICLE ACCIDENT DESKBOOK § 12.2(5) (1988)).
    The case before us now is very much like Geschwind—or at least it would
    have been, if the trial court had allowed Cove to present its defense. In
    Geschwind, we explained that a jury could find Geschwind more than 50 percent at
    fault—even though he didn’t cause the accident—because it was conceivable that
    Geschwind made the negligent decision to ride with a severely intoxicated driver
    because he was too intoxicated to appreciate the risk. Here, a jury could have
    found Gerlach more than 50 percent at fault—even if the jury also allocated to
    Cove some percentage of fault—because it is conceivable that Gerlach made the
    poor decision to climb over the balcony or she was physically unable to do so
    because she was severely intoxicated. But Cove’s argument was curtailed by the
    trial court’s decision to bar evidence that would have revealed just how intoxicated
    Gerlach was and what effect that intoxication had on her.
    The trial court incorrectly reasoned that Geschwind does not apply to this
    case because in Geschwind, it was undisputed that Geschwind got in the car with a
    drunk driver, but in this case, whether Gerlach climbed the balcony was disputed.
    1 VRP (June 12, 2017) at 1005-07. But our opinion in Geschwind did not turn on
    whether or not the parties contested the facts. And for good reason: the jury, not
    12
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    the court, serves as factfinder. See Geschwind, 
    121 Wn.2d at 839-40
    . The degree
    of Gerlach’s intoxication would have helped the factfinder resolve the disputed
    facts and determine whether Cove proved its intoxication defense. Instead, the
    trial court excluded evidence that went to the heart of Cove’s statutory defense,
    stripping the jury of its fact-finding function.
    All the trial court allowed the jury to learn was that Gerlach was “under the
    influence of intoxicating liquor.” 1 VRP (June 22, 2017) at 2799-800. But it is
    one thing to have a BAC of 0.08, the threshold for driving under the influence,
    RCW 46.61.502, and another thing entirely to have a BAC of 0.238. Gerlach’s
    BAC was more than “minimally relevant to Cove’s affirmative defense.” Majority
    at 2. It was the key piece of evidence to Cove’s legislatively defined affirmative
    defense. If our abuse-of-discretion standard of review insulates this trial court’s
    exclusion of such probative evidence from serious appellate review, then perhaps it
    is time for this court to reevaluate that standard.
    C. The trial court erred in excluding testimony from Dr. Vincenzi
    Under our evidence rules, an expert may testify if he or she is qualified and
    his or her testimony will help the trier of fact. ER 702; see also L.M. v. Hamilton,
    
    193 Wn.2d 113
    , 134, 
    436 P.3d 803
     (2019). To be helpful, the testimony must be
    reliable and have an adequate foundation. L.M., 193 Wn.2d at 137. An expert may
    13
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    base an opinion on “facts or data . . . made known to the expert,” even if the expert
    did not personally “perceive[ ]” those facts or data. ER 703. “[A]n expert is not
    always required to personally perceive the subject of his or her analysis.” In re
    Marriage of Katare, 
    175 Wn.2d 23
    , 39, 
    283 P.3d 546
     (2012) (citing ER 703).
    “That an expert’s testimony is not based on a personal evaluation of the subject
    goes to the testimony’s weight, not its admissibility.” Id.; see also In re Disability
    Proceeding Against Keefe, 
    159 Wn.2d 822
    , 831, 
    154 P.3d 213
     (2007) (holding that
    “an in-person evaluation . . . may have strengthened [the expert’s] testimony,” but
    the evidence rules do not “require such firsthand knowledge”).
    Despite this well-settled legal principle, the majority faults Dr. Vincenzi for
    not personally evaluating Gerlach. Majority at 10. The majority suggests that Dr.
    Vincenzi should have subjected Gerlach to a battery of examinations to determine
    her particular burn-off rate ration for alcohol, her particular absorption rate for
    alcohol, and her particular metabolic rate for alcohol. 
    Id.
     But we have clearly held
    that such criticisms go to the weight of the expert’s testimony, not its admissibility.
    Keefe, 
    159 Wn.2d at 831
    . Neither our precedent nor our evidence rules require Dr.
    Vincenzi to possess the firsthand knowledge of Gerlach that the majority demands
    of him.
    14
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    Next, the majority holds that Dr. Vincenzi’s testimony was too speculative
    because he did not know exactly what happened on the night of the accident.
    Majority at 12-13. But nobody knew exactly what happened; figuring that out was
    the main issue at trial and what the jury was tasked with resolving. Cove hoped to
    defend itself by presenting its theory of what happened: Gerlach made a poor
    decision to attempt to climb over the balcony, she made that decision because she
    was drunk, and she was unable to successfully climb over the balcony because she
    was too intoxicated. The majority would have you believe that the only piece of
    evidence Cove had to support its theory was Gerlach’s BAC. See majority at 16
    (holding that the BAC results were inadmissible because Cove lacked “other
    evidence or testimony that could connect Gerlach’s BAC results to behavior that
    caused her fall”). But that’s not right. Cove had an accident reconstructionist
    testify that given how Gerlach landed and her injuries, she must have been
    climbing. 1 VRP (July 6, 2017) at 2998-3000. Cove also had an expert
    pharmacologist, Dr. Vincenzi, ready and able to explain why Gerlach’s severe
    intoxication might have led her to decide to climb and how her severe intoxication
    would have impeded her ability to do so. 2 VRP (June 14, 2017) at 1531-36. And
    Dr. Vincenzi was not merely speculating as to Gerlach’s level of intoxication; he
    was able to use her BAC results to calculate just how intoxicated she was prior to
    15
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    her fall. CP at 511. The BAC was but one piece, albeit a pivotal piece, to the
    puzzle that was Cove’s entire defense.
    Speaking of BAC, a recent case provides the quintessential example of a
    case, quite unlike this one, in which an expert opinion as to intoxication is too
    speculative. In that case, the plaintiff, Needham, sued his medical provider for
    negligence. Needham v. Dreyer, 11 Wn. App. 2d 479, 486, 
    454 P.3d 136
     (2019),
    review denied,

     (2020). Over Needham’s objection, the trial court
    allowed defense experts to testify that the plaintiff’s alcohol use may have caused
    his injury. 
    Id.
     Like Gerlach, Needham had argued that the testimony should be
    excluded as speculative. 
    Id.
    The Court of Appeals agreed with Needham and reversed. Id. at 493. The
    court reasoned that the expert testimony was speculative because nobody knew
    how intoxicated Needham had been. Id. at 496. Although Needham had admitted
    to drinking on the day he collapsed, id. at 495, “there was no evidence in the record
    as to either Needham’s BAC level or whether Needham drank a sufficient amount
    of alcohol that night to cause his collapse.” Id. at 496. “Furthermore, Needham
    had no alcohol in his system when admitted into the hospital.” Id. “[W]ith no
    record or evidence of his blood alcohol level at the time of the collapse,” the
    experts were merely speculating “as to the amount of alcohol consumed prior to
    16
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    the collapse” and “as to the potential effect of alcohol on Needham’s collapse.” Id.
    The Court of Appeals held that such speculative testimony should have been
    excluded. Id.
    But the exact opposite is true here. Unlike Needham, Gerlach had a lot of
    alcohol in her system when she was admitted to the hospital. Dr. Vincenzi, a
    professor emeritus of pharmacology at the University of Washington, used the
    blood draw from the hospital to calculate how drunk she was when she fell. See
    ER 702 (allowing an expert to base an opinion on facts made known to the expert).
    Without a BAC level, I might agree that Dr. Vincenzi lacked an adequate
    foundation on which to form an opinion and was merely speculating. But with a
    BAC level, Dr. Vincenzi’s testimony had an adequate foundation and would have
    been incredibly helpful to the jury as it decided whether Cove proved its statutory
    defense.
    D. The trial court’s errors were prejudicial
    A trial court’s error is reversible only if it is prejudicial. Brown v. Spokane
    County Fire Prot. Dist. No. 1, 
    100 Wn.2d 188
    , 196, 
    668 P.2d 571
     (1983) (citing
    Thomas v. French, 
    99 Wn.2d 95
    , 104, 
    659 P.2d 1097
     (1983)). “Error will not be
    considered prejudicial unless it affects, or presumptively affects, the outcome of
    the trial.” 
    Id.
     (citing James S. Black & Co. v. P&R Co.,

    (Gordon McCloud, J., concurring in part/dissenting in part)
    
    530 P.2d 722
     (1975)). I agree with the Court of Appeals’ conclusion that the trial
    court’s errors in this case were prejudicial. Gerlach v. Cove Apts., LLC, 8 Wn.
    App. 2d 813, 823, 
    446 P.3d 624
    , review granted, 
    193 Wn.2d 1037
     (2019).
    Without the BAC reading or Dr. Vincenzi’s testimony, Cove’s hands were
    tied and the degree of Gerlach’s intoxication was repeatedly deemphasized. Even
    the trial court deemphasized her intoxication. 1 VRP (July 7, 2017) at 3362-63
    (stating that it did not want to “overemphasize[ ]” Gerlach’s intoxication). Nathan
    Miller, Gerlach’s then-boyfriend, testified that he “wasn’t really paying attention”
    to whether Gerlach was drinking and stated that “it would be a guess that she was
    drinking.” 1 VRP (June 21, 2017) at 2362. The other friends present that night
    testified that they didn’t recall how much Gerlach had to drink. 1 VRP (June 22,
    2017) at 2629-31, 2752. And although Gerlach had admitted in a deposition that
    she had been drunk when she fell, the trial court excluded her admission, reasoning
    that “to be an admission, you have to remember what it is you’re admitting.” Id. at
    2718. As the Court of Appeals concluded, the trial court’s rulings “resulted in a
    complete absence of evidence as to the extent of her intoxication” and “prejudiced
    Cove’s ability to prove its affirmative defense.” Gerlach, 8 Wn. App. 2d at 822-
    23. I would affirm.

    (Gordon McCloud, J., concurring in part/dissenting in part)
    II.      The majority’s extended discussion of the implied warranty of
    habitability is unnecessary dicta
    As the majority notes, “the jury in this case used a verdict form that did not
    distinguish between negligence premised on Cove’s common law duties and
    negligence premised on Cove’s duties under the RLTA.” Majority at 28. The
    majority also notes that Cove’s “common law claims were based on premises
    liability, not the implied warranty of habitability.” Majority at 21 n.9.
    Nevertheless, the majority engages in an extensive analysis of the implied warranty
    of habitability. I decline to join that part of the majority’s opinion. See In re Det.
    of Reyes, 
    184 Wn.2d 340
    , 350, 
    358 P.3d 394
     (2015) (Stephens, J., concurring)
    (criticizing the majority for an “entire discussion” that amounted to “unnecessary
    dicta”).
    Because the majority spends so much time on it, however, I feel compelled
    to note that in expanding the scope of the implied warranty of habitability, the
    majority heavily relies on Foisy v. Wyman, 
    83 Wn.2d 22
    , 
    515 P.2d 160
     (1973).
    That case, which was neither a personal injury case nor a case involving a
    nontenant, is easily distinguishable. 
    Id. at 23
    . There, we held “that in all contracts
    for the renting of premises, oral or written, there is an implied warranty of
    habitability and breach of this warranty constitutes a defense in an unlawful
    detainer action.” 
    Id. at 28
     (emphasis added) (citing numerous out-of-jurisdiction
    19
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    cases). We remanded the case for the factfinder to determine “[w]hether the
    evidence indicates that the premises were totally or partially uninhabitable during
    the period of habitation.” 
    Id. at 34
    . If the factfinder determined that the premises
    was uninhabitable, then the plaintiff could not succeed on his claim of unpaid rent.
    
    Id.
    Thus, under Foisy, a tenant can succeed in an unlawful detainer action by
    proving that the premises are uninhabitable. But Foisy says nothing about whether
    a nontenant (or even a tenant) can rely on the implied warranty of habitability to
    succeed in a personal injury action. Perhaps we should build on Foisy and craft the
    new common law rule that the majority advocates for today. But Foisy does not
    compel that result, and I would wait for the case that squarely presents the issue
    before ruling.
    Additionally, the majority fails to grapple with what it means for a dwelling
    to be “uninhabitable.” This is an open question in our court. See Pinckney v.
    Smith, 
    484 F. Supp. 2d 1177
    , 1182 (W.D. Wash. 2007) (“Washington appellate
    courts have reached opposing conclusions as to what conditions are sufficiently
    dangerous to qualify a residence as uninhabitable and the Washington Supreme
    Court has not decided the issue.”). In Foisy, the case in which we first recognized
    the implied warranty of habitability, the dwelling “contained a number of defects
    20
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    including a lack of heat, no hot water tank, broken windows, a broken door, water
    running through the bedroom, an improperly seated and leaking toilet, a leaking
    sink in the bathroom, broken water pipes in the yard and termites in the basement.”
    
    83 Wn.2d at 24-25
    . In other words, the dwelling was almost certainly
    uninhabitable.
    In contrast, in Klos v. Gockel, we held that a damaged patio and backyard
    did not render the dwelling sufficiently “uninhabitable.” 
    87 Wn.2d 567
    , 571-72,
    
    554 P.2d 1349
     (1976). Since the house remained habitable, we held that the
    implied warranty had not been breached. 
    Id. at 571-72
     (“The law of implied
    warranty is not broad enough to make the builder-vendor of a house absolutely
    liable for all mishaps occurring within the boundaries of the improved real
    property.”). We have since explained that courts should evaluate the implied
    warranty of habitability on “a case-by-case basis.” Atherton Condo. Apt.-Owners
    Ass’n Bd. of Dirs. v. Blume Dev. Co., 
    115 Wn.2d 506
    , 520, 
    799 P.2d 250
     (1990)
    (holding that claimed violations of the fire code might affect habitability and must
    survive summary judgment). But no case-by-case analysis has been conducted
    here, because the implied warranty of habitability is not at issue.
    In short, our precedent does not dictate that Cove necessarily breached the
    implied warranty of habitability by failing to replace the rotted balcony railing.
    21
    Gerlach v. Cove Apartments, LLC, et al., No. 97325-3
    (Gordon McCloud, J., concurring in part/dissenting in part)
    Nor is it clear that a nontenant may rely on the implied warranty to recover in a
    personal injury suit. Since I would wait for those issues to present themselves
    before we decide them, I do not join the majority opinion on this point.
    CONCLUSION
    The trial court abused its discretion by excluding Gerlach’s BAC and Dr.
    Vincenzi’s testimony. I dissent from the majority on this point and would affirm
    the Court of Appeals.
    Although I concur in the majority’s analysis of the RLTA, I do not join its
    unnecessary discussion of the implied warranty of habitability. I therefore
    respectfully concur in part and dissent in part.
