    Gruendel, Prescott and Bear, Js.*

    Fairfield, Hon. George N. Thim, judge trial referee.)

    Opinion
    BEAR, J. The defendant Bruce Fern, Sr., appeals from
    the judgment of the trial court in favor of the plaintiff,
    Vermont Mutual Insurance Company. The plaintiff
    brought this subrogation action against the defendant
    and his son, the defendant Bruce Fern, Jr.,1 to recover
    damages resulting from a fire occurring on a residential
    property on November 6, 2011. The defendant argues
    that the court erred in determining that (1) the defen-
    dant owed a duty to the plaintiff’s insured and (2) the
    defendant installed a boiler and was equally at fault
    with his son. We affirm the judgment of the trial court.
    In its memorandum of decision, the court made the
    following findings of fact. The defendant and his son
    both work as contractors, although only the defendant
    is a registered improvement contractor. Although both
    had some prior experience in installing new boilers,2
    neither the defendant nor his son has the necessary
    occupational license to engage in plumbing and piping
    work or heating, piping, and cooling work.
    Charles Loria (insured) was the owner of property
    located at 155 Twin Lanes Road in Easton (property),
    on which he possessed an insurance policy issued by
    the plaintiff. At the time of the fire, the insured’s former
    wife, Elizabeth Loria (occupant), lived on the property
    with her children.3 She told investigators subsequent to
    the fire that the defendant and his son had installed the
    boiler about a week before the fire occurred.
    On the day of the installation, the defendant and his
    son arrived at the property, removed the old boiler, and
    installed the new boiler. The defendant was responsible
    for certain aspects of the installation of the new pipe
    connecting the boiler to the chimney. This work
    involved measuring the pipe, making the proper cuts,
    and installing the adapter4 that connected the pipe and
    chimney into the masonry. When installing the chimney
    connector into the masonry, the defendant used a two-
    by-four board to knock the adapter into the chimney.
    He also held the pipe in place while his son affixed the
    adapter and the pipe to one another. No further action,
    such as the use of cement or strapping the pipe in place,
    was taken to secure the chimney connector into the
    chimney. The defendant did not read the installation
    manual for the boiler or speak with a building inspector
    about the applicable regulations governing the installa-
    tion of the boiler. The defendant’s son ignited the boiler,
    but failed to make any adjustments to the appliance as
    required by the manufacturer.
    Approximately one week after the defendant and his
    son installed the boiler, the chimney connector became
    disconnected from the masonry.5 As a result, exhaust
    gases from the boiler were directed onto the joists of
    the basement ceiling and, over time, generated suffi-
    cient heat to start the fire. From the basement, the
    fire spread to other parts of the property, resulting in
    damages exceeding $350,000.
    During the subsequent investigation into the fire, two
    potential causes were identified as causing the fire.
    First, the boiler had not been placed to the proper
    settings and adjusted as required during the initial
    installation; consequently, the boiler had been running
    improperly and accumulated a large amount of soot.
    Second, the chimney connector had not been cemented
    into the chimney or secured in place by a separate piece
    of equipment; consequently, it became dislodged from
    the chimney. One of the investigators stated that, if the
    chimney connector had been secured properly into the
    chimney, the connector would not have become discon-
    nected due to the improper installation and adjustment
    of the burner.
    In its amended complaint, the plaintiff asserted two
    theories for recovery: (1) the defendant and his son
    had acted negligently in installing the boiler (counts
    one and three); and (2) they had breached an implied
    covenant that all work would be performed in a work-
    manlike manner (counts two and four). Following a
    trial to the court, the court issued its memorandum of
    decision on February 26, 2015. Recounting the essen-
    tials of this chronology, the court found that both the
    defendant and his son had violated various statutes and
    regulations while installing the boiler. Consequently,
    the court held that the defendant and his son had acted
    negligently and violated an implied covenant that their
    work would be done in a workmanlike manner, their
    actions were the proximate cause of the fire, and they
    were equally at fault. Therefore, the court found in favor
    of the plaintiff on each count of its complaint. This
    appeal followed.
    I
    On appeal, the defendant primarily asserts that the
    court erred in finding that he owed a duty to the insured
    or the occupant. The defendant asserts that the
    resulting fire was unforeseeable to him because his role
    in installing the boiler was relatively limited. In making
    this argument, the defendant relies on the difference
    in the type and character of his work when compared
    to that of his son. In particular, the defendant asserts
    that his son was the contractor retained or engaged by
    the occupant, made the agreement to install the boiler,
    held himself out as having the necessary skill and exper-
    tise to install the boiler, and, thus, had the ultimate
    responsibility for verifying that the boiler was properly
    installed. The defendant frames his personal involve-
    ment much more narrowly, contending that he was
    merely a laborer or helper, rather than a subcontractor,
    and claims as support that he took direction from his
    son, was not paid for his labor, and never held himself
    out as having any skill whatsoever in boiler installation.
    We disagree.
    We begin by noting that the defendant’s argument
    appears to confuse the existence of a duty with the
    scope of that duty once one is found to exist;6 thus, he
    blends together two separate concerns. ‘‘The essential
    elements of a cause of action in negligence are well
    established: duty; breach of that duty; causation; and
    actual injury. . . . Contained within the first element,
    duty, there are two distinct considerations. . . . First,
    it is necessary to determine the existence of a duty,
    and [second], if one is found, it is necessary to evaluate
    the scope of that duty. . . . The issue of whether a
    duty exists is a question of law . . . which is subject
    to plenary review. We sometimes refer to the scope of
    that duty as the requisite standard of care.’’ (Internal
    quotation marks omitted.) Doe v. Hartford Roman
    Catholic Diocesan Corp., 
    317 Conn. 357
    , 373, 
    119 A.3d 462
    (2015).
    ‘‘A duty to use care may arise from a contract, from
    a statute, or from circumstances under which a reason-
    able person, knowing what he knew or should have
    known, would anticipate that harm of the general nature
    of that suffered was likely to result from his act or
    failure to act.’’ Coburn v. Lenox Homes, Inc., 
    186 Conn. 370
    , 375, 
    441 A.2d 620
    (1982). Although ‘‘[t]he ultimate
    test of the existence of a duty to use care is found
    in the foreseeability that harm may result if it is not
    exercised . . . [f]oreseeability in this context is a flexi-
    ble concept, and may be supported by reasonable reli-
    ance, impeding others who might seek to render aid,
    statutory duties, property ownership or other factors.’’

    v. Middletown, 
    314 Conn. 303
    , 323, 
    101 A.3d 249
    (2014).
    In holding that the defendant was liable for the fire,
    the court did not engage in a separate analysis concern-
    ing whether it was foreseeable that a fire could occur.
    Instead, it relied on two groups of statutes and regula-
    tions that the defendant and his son contravened while
    installing the boiler. It first noted that although neither
    the defendant nor his son had the occupational license
    required by statute for this work, they wilfully engaged
    in this work and the fire was ‘‘[t]he harm that . . . the
    licensing requirement was designed to prevent.’’ It also
    noted that certain codes and standards promulgated by
    the National Fire Protection Association (standards)
    had been incorporated into our law and were not fol-
    lowed by the defendant. Thus, in effect, the court ana-
    lyzed duty as a question of negligence per se under
    these two groups of statutes and regulations.7
    ‘‘Negligence per se . . . serves to superimpose a leg-
    islatively prescribed standard of care on the general
    standard of care. . . . A violation of the statute or regu-
    lation thus establishes a breach of duty when (1) the
    plaintiff is within the class of persons intended to be
    protected by the statute, and (2) the injury is the type
    of harm that the statute was intended to prevent. . . .
    Although the plaintiff still must demonstrate the
    remaining elements of negligence, the jury in a negli-
    gence per se case need not decide whether the defen-
    dant acted as an ordinarily prudent person would have
    acted under the circumstances. [It] merely decide[s]
    whether the relevant statute or regulation has been
    violated. If it has, the defendant was negligent as a
    matter of law.’’ (Citations omitted; footnote omitted;

    (2013).
    ‘‘Generally, our courts have treated a statutory viola-
    tion as negligence per se in situations in which the
    statutes or city ordinances at issue have been enacted
    for the purpose of ensuring the health and safety of
    members of the general public.’’ (Internal quotation

    122 Conn. App. 555
    , 580, 
    1 A.3d 137
    (2010). Our Supreme
    Court has held on prior occasions that legislative enact-
    ments that contain criminal penalties could qualify as
    the statutory predicate for negligence per se claims.

    158 Conn. 92

    , 204,

    (1903) (violation of ordinance
    misdemeanor punishable by fine).
    ‘‘[I]n determining whether a duty of care is owed
    to a specific individual under a statute, the threshold
    inquiry . . . is whether the individual is in the class of
    persons protected by the statute.’’ Ward v. Greene, 
    267 Conn. 539
    , 548, 
    839 A.2d 1259
    (2004). ’’In determining
    the class of persons protected by a statute, we do not
    rely solely on the statute’s broad policy statement.
    Rather, we review the statutory scheme in its entirety,
    including the design of the scheme as enacted.’’ (Inter-

    Id., 551.8 Turning
    first to the licensure requirements, General
    Statutes § 20-330 et seq., our Supreme Court has stated
    that ‘‘a primary purpose of the licensure requirement,
    in addition to establishing a uniform, statewide system
    of licensing, is to protect the public health and safety.’’
    Hartford Hospital v. Dept. of Consumer Protection, 
    243 Conn. 709
    , 719–20, 
    707 A.2d 713
    (1998). In a dissenting
    opinion, Justice Berdon similarly stated that ‘‘[t]he pri-
    mary purpose of the licensing requirement . . . was to
    protect the general consuming public from unqualified
    and/or unscrupulous contractors.’’ 
    Id., 726. Discussing
    the legislative history, he quoted one industry profes-
    sional, who said that ‘‘the purpose of [General Statutes
    § 20-334] is to protect the public and maintain certain
    minimum standards in competence to the public.’’
    (Emphasis added; internal quotation marks omitted.)
    
    Id., 726, quoting
    Conn. Joint Standing Committee Hear-
    ings, General Law, Pt. 3, 1965 Sess., pp. 1138–39.
    Pursuant to § 20-334 (a), no person is allowed to
    perform any work covered in chapter 393 of the General
    Statutes unless they (1) possess a license in the covered
    occupation or work, or (2) have appropriately regis-
    tered as an apprentice and are subject to the regulations
    governing that training. One such broad category requir-
    ing a license or permit is heating, piping, and cooling
    work.9 General Statutes § 20-330 (5); see also Regs.,
    Conn. State Agencies § 20-332-5. The requirement that
    a contractor working in this field must be appropriately
    credentialed is intended to ensure that the person per-
    forming the work has the requisite skill and knowledge
    within the trade, or is at the very least supervised by
    an individual with that skill and knowledge. See General
    Statutes §§ 20-333 and 20-334 (a).10
    Persons engaging in work without having the neces-
    sary license pursuant to these provisions of the General
    Statutes may be subject to both criminal and civil conse-
    quences. As recognized by the court, wilfully engaging
    in work covered by chapter 393 without the necessary
    license or permit is a class B misdemeanor. General
    Statutes § 20-341 (a). Other subsections provide civil
    consequences by authorizing the appropriate board or
    the Commissioner of Consumer Protection to impose
    penalties on unlicensed individuals engaging in work
    that requires a license under chapter 393; see General
    Statutes § 20-341 (b); and by making violations of the
    provisions of this chapter a basis for a claim pursuant
    to the Connecticut Unfair Trade Practices Act.11 See
    General Statutes § 20-341 (d).
    Finally, we note that the legislature explicitly has
    defined circumstances where a license would not be
    required to engage in otherwise covered work; see, e.g.,
    General Statutes § 20-340; and our Supreme Court has
    construed the exceptions strictly. See Hartford Hospi-
    tal v. Dept. of Consumer 
    Protection, supra
    , 
    243 Conn. 720
    . It is axiomatic that parties are presumed to know
    the law. Provident Bank v. Lewitt, 
    84 Conn. App. 204
    ,
    209, 
    852 A.2d 852
    , cert. denied, 
    271 Conn. 924
    , 
    859 A.2d 580
    (2004). The activities of the defendant and his son
    do not fall within any of the exceptions to the licensure
    requirement, and, therefore, the owner of the home,
    whether the insured or the occupant, was within the
    class of persons intended to be protected by the licen-
    sure requirement.12
    With respect to the type of harm covered by this
    statutory scheme, our Supreme Court has noted these
    requirements are intended to ensure an appropriate
    level of competence by individuals in the provision of
    certain services to the public. See Hartford Hospital
    v. Dept. of Consumer 
    Protection, supra
    , 
    243 Conn. 720
    (because nature of plumbing work in hospital is ‘‘critical
    to health and safety of patients’’ and because of greater
    public safety risks from faulty plumbing in entities pro-
    viding services to the public, ‘‘it is likely that the legisla-
    ture intended those performing such work to meet the
    highest professional standards’’); see also 
    id., 726 (Ber-
    don, J., dissenting) (statement in legislative history
    quoted by dissent that purpose of licensure statute is
    to maintain minimum standards of competence for pub-
    lic). The statutory focus on ensuring appropriate com-
    petence is unsurprising, as there is a foreseeable risk
    of harm to people and property from the improper
    installation, maintenance, or operation of many of the
    appliances involved in occupations and work covered
    by chapter 393. Cf. State v. Salz, 
    226 Conn. 20
    , 33–38,
    
    627 A.2d 862
    (1993) (affirming manslaughter conviction
    of electrician, whose wiring of neighbor’s electric
    heater in violation of code provisions and failure to
    ensure necessary inspections resulted in fire and neigh-
    bor’s death); Reciprocal Exchange v. Altherm, Inc., 
    142 Conn. 545
    , 549–53, 
    115 A.2d 460
    (1955) (affirming liabil-
    ity for servicers’ negligent failure to determine cause of
    malfunctioning oil burner or warn owner to discontinue
    use of burner, which was factor in explosion); Beauvais
    v. Springfield Institute for Savings, 
    303 Mass. 136
    , 142,
    
    20 N.E.2d 957
    (1939) (improper installation of oil burner
    in commercial building resulted in explosion, which
    caused tenant’s death); Executive Board of Missouri
    Baptist General Assn. v. Campbell, 
    275 S.W.2d 388
    , 392
    (Mo. App. 1955) (failure to properly adjust electrodes
    in furnace burner resulted in explosion). Pursuant to
    the regulatory scheme adopted in Connecticut for heat-
    ing and cooling licenses, a license seeker must demon-
    strate that he both has the necessary experience and
    training to qualify for the license that he seeks and
    possesses a baseline proficiency of knowledge through
    the examination itself. See footnote 11 of this opinion.
    Thus, a fire resulting from the improper installation of a
    heating apparatus by a statutorily unqualified individual
    would be one such harm that the licensing statutes
    were intended to prevent. Cf. Hartford Hospital v. Dept.
    of Consumer 
    Protection, supra
    , 719.13
    Second, the court found that standards 31 and 211,
    which have been incorporated into our state law,14 spec-
    ified the manner in which a chimney connector must
    be secured; a secure connection was required by these
    standards and the manufacturer’s instructions; and the
    chimney connector was required to be clamped and
    cemented in place, but was not secured as required.
    Pursuant to the applicable regulations governing the
    installation of oil burners and provisions of our building
    code, a chimney connector must be firmly cemented
    to the masonry unless a thimble is used.15 There was
    testimony at trial, however, that the preexisting con-
    crete ring was not a thimble of the type required by
    standard 31,16 and the defendant conceded at argument
    before this court that the installed pipe was not
    strapped, cemented, or secured as required by the appli-
    cable regulations. Thus, the defendant owed, and by
    his own concession breached, a duty pursuant to these
    regulations, regardless of his role in the process. See
    Buravski v. DiMeola, 
    141 Conn. 726
    , 728–29, 
    109 A.2d 867
    (1954) (‘‘It is, of course, the rule that when a person
    violates a statute or an ordinance enacted for the protec-
    tion of the public, he is guilty of negligence as a matter
    of law. . . . This rule applies even though the person
    is ignorant of the existence of the statute or ordinance.
    He is chargeable with knowledge on the theory that
    ignorance of the law excuses no one.’’ [Citation
    omitted.]).
    The defendant has presented no case law in support
    of his position that the injury was not foreseeable
    because he was acting merely as a laborer, rather than
    as a trained boiler installer. We reject his reliance on
    this position for several reasons. To begin, the court
    determined that the defendant’s duty to the plaintiff’s
    insured arose primarily under legislative enactments,
    not pursuant to the common-law duty to exercise due
    care. Any subsequent foreseeability analysis concerning
    the duty owed by the defendant under the statutory
    scheme, therefore, would focus on the party injured
    and the harm suffered; see Ward v. 
    Greene, supra
    , 
    267 Conn. 555
    ; and a defendant can be held liable even
    without actual knowledge that his actions violated any
    statute. See Commercial Union Ins. Co. v. Frank Per-
    rotti & Sons, Inc., 
    20 Conn. App. 253
    , 260, 
    566 A.2d 431
    (1989) (defendant’s argument that it was unaware that
    combustible liquid was in trash irrelevant when ordi-
    nance required it to separate out combustible
    materials).17
    Further, we note that not all injuries that potentially
    might occur during the performance of work requiring
    an occupational license are outside the realm of ordi-
    nary knowledge and experience. See Utica Mutual Ins.
    Co. v. Precision Mechanical Services, Inc., 122 Conn.
    App. 448, 456, 
    998 A.2d 1228
    (expert testimony not
    necessary to demonstrate failure of licensed plumber
    to use reasonable care ‘‘in operating plumber’s torch
    in vicinity of combustible materials’’), cert. denied, 
    298 Conn. 926
    , 
    5 A.3d 487
    (2010). Thus, even if we were
    to rely on the common-law test for determining the
    foreseeability of an injury,18 we would conclude that
    the injury in this case was foreseeable. The defendant
    testified at trial that he knew that products such as the
    boiler frequently come with instruction manuals and
    that he was aware of the building codes and how to
    find out what those codes require.19 If he had consulted
    either the instruction manual for the boiler or a building
    inspector, as he has done in the past when he had
    questions about the applicable codes, he would have
    been aware that the chimney connector here should
    have been cemented or otherwise secured into the flue.
    Additionally, specialized knowledge and training are
    not required to know that the general purpose of a flue
    or chimney is to carry heated gases away from a heat-
    generating source. See, e.g., Random House Webster’s
    Unabridged Dictionary (2d Ed. 2001) (defining chimney
    as ‘‘a structure . . . containing a passage or flue by
    which the smoke, gases, etc., of a fire or furnace are
    carried off’’). Indeed, the defendant testified that he did
    not need any instructions from his son to know that
    the chimney connector must be secured as much as
    possible. Because it is within the understanding of an
    ordinary person that improperly installing the chimney
    connector for an oil burner could lead to a fire, the
    court reasonably could have found that the risk of fire
    arising from an improperly secured chimney connector
    either was, or at the very least should have been, fore-
    seeable to the defendant.20 See Ruiz v. Victory Proper-
    ties, LLC, 
    315 Conn. 320
    , 335, 
    107 A.3d 381
    (2015) (‘‘[as]
    long as harm of the general nature as that which
    occurred is foreseeable there is a basis for liability even
    though the manner in which the accident happens is
    unusual, bizarre or unforeseeable’’ [internal quotation
    marks omitted]); see also Doe v. Hartford Roman Cath-
    olic Diocesan 
    Corp., supra

    II
    The defendant also claims that the court erred in
    determining that the defendant ‘‘installed a boiler’’ and
    was equally at fault with his son. We disagree.
    ‘‘[Q]uestions of fact are subject to the clearly errone-
    ous standard of review. . . . A finding of fact is clearly
    erroneous when there is no evidence in the record to

    support it, the reviewing court on the entire evidence
    is left with the definite and firm conviction that a mis-
    take has been committed. . . . Because it is the trial

    , 206 (2015).
    In its memorandum of decision, the court presented
    the following account of the actions of the defendant
    and his son while installing the boiler: ‘‘The defendants
    worked nine hours together in the Loria residence on
    November 2nd or 3rd. They removed the old boiler and
    [chimney connector] and installed a new boiler and
    [chimney connector]. [The defendant] cut pipes and
    held them in place while his son soldered them together.
    Both worked on installing the [chimney connector].
    [The defendant] connected the end of the metal pipe to
    the chimney, but did not cement it in place or otherwise
    fasten it to the chimney. He merely pounded it in place
    with a wood board. He did not read the manufacturer’s
    instruction booklet or check with a building inspector.
    His son turned on the oil-fired boiler, but did not make
    any adjustments to the burner motor as required by the
    manufacturer.’’ It then found that ‘‘the fire was proxi-
    mately caused by [the defendant and his son’s] careless
    and improper installation of the boiler and [chimney
    connector],’’ and that they were equally at fault.
    The defendant argues that the court erred in charac-
    terizing his participation and responsibility as equiva-
    lent to that of his son. The defendant notes that the court
    made no specific finding that the defendant’s manner of
    inserting the pipe into the chimney was negligent, but
    ‘‘simply treat[ed] [the defendant] as having undertaken
    to install the boiler along with his son, and charge[d]
    [the defendant] with negligence in the overall improper
    installation of the boiler—the entire job. That conclu-
    sion is flawed, however, [insofar as it is based on the
    arguments that the defendant’s] status with respect to
    the job was as a laborer’’ and ‘‘it was the responsibility
    of [the defendant’s son] to ensure that the new boiler
    and all appurtenances were installed correctly.’’ In mak-
    ing this argument, the defendant has alleged facts that
    the court did not find.
    Although relying on certain facts throughout his brief
    that the court did not adopt in its memorandum of
    decision, the defendant points to no separate error in
    the court’s findings beyond this particular characteriza-
    tion and presents no independent argument beyond his
    conclusory position that the role of his son before and
    during the installation of the boiler somehow neutral-
    izes his own responsibility to act in compliance with
    the applicable statutory provisions and in exercise of
    due care. Further, the court’s recitation of the work
    completed by the defendant and his son was an accu-
    rate, if truncated, recitation of the defendant’s and his
    son’s testimony at trial about their actions at the prop-
    erty in late 2011. Although the court did not discuss in
    detail the evidence showing that the defendant’s son
    arranged many of the project’s details prior to the day
    of the actual installation, both the defendant and his
    son presented similar accounts of their work at the
    property and used terms suggestive of joint efforts to
    describe their labor.22 With respect to the installation
    of the chimney connector itself, it is undisputed that
    the defendant was responsible for preparing most of
    the piping for the chimney connector, reinstalled the
    end of the chimney connector into the flue, and held
    the pipes while his son affixed them to one another.
    The defendant’s son testified that he was not actively
    supervising the defendant’s work in this respect,23 and
    the defendant testified that he did not need any direc-
    tion to reinstall the chimney connector or to know that
    he had to make the connection as secure as possible.
    We also note that the court explicitly found that it was
    the defendant, not his son, who inserted the chimney
    connector into the masonry and failed to properly affix
    it, and the defendant does not challenge this finding
    of fact.
    Further, expert testimony offered at trial stated that
    the fire was caused by the improper adjustment of the
    boiler following its initial ignition by the defendant’s son
    and the failure of the defendant to secure the chimney
    connector into the flue properly. These experts also
    testified, however, that the failure to secure the chimney
    connector properly into the chimney was primarily
    responsible for the fire or, at the very least, that the
    fire would have been significantly less likely to occur,
    even with the improper adjustment of the boiler set-
    tings, if the connector had been secured properly. Thus,
    despite the defendant’s reliance on certain assertions
    and testimony presented at trial that were not adopted
    by the court or challenged on appeal, it was not clearly
    erroneous for the court to characterize the defendant’s
    labors or responsibility for the resulting fire as equiva-
    lent to that of his son.
    In summation, the defendant engaged in specialized
    work that he knew or should have known required a
    professional license that he did not possess. The defen-
    dant failed to take necessary precautions when doing
    this specialized work that required a licensed profes-
    sional and failed to install the chimney connector in
    accordance with applicable law and regulations.
    Accordingly, the defendant failed to exercise due care
    when undertaking this specialized endeavor. Because
    the risk of a fire was both within the contemplation of
    the applicable statutes and regulations of which the
    defendant was in violation, and the damages sustained
    were a foreseeable result of the improper installation
    of the chimney connector to the oil-fired boiler, the
    defendant’s arguments that he did not owe a duty to
    the plaintiff’s insured are without merit.
    The judgment is affirmed.
    In this opinion the other judges concurred.

    will refer to Bruce Fern, Sr., as the defendant in this opinion.

    Specifically, the court described their experience as follows: ‘‘[The defen-
    dant] and [his son] have limited experience in installing boilers. Thirty years
    ago, [the defendant] helped a friend install a boiler. A long time ago, [the
    defendant’s son] installed two boilers.’’
    3
    Neither the occupant nor the children were home at the time of the fire
    or for almost twenty-four hours prior to the fire.
    4
    The defendant’s son testified that an adapter, or reducing collar, is the
    conical piece of metal that connected the pipe from the boiler to the flue.
    5
    Evan Haynes, a licensed mechanical engineer who assisted in the investi-
    gation, determined that one of two causes likely resulted in the chimney
    connector becoming disconnected: ‘‘[The chimney connector] could simply
    just fall out through vibration or use. It also could fall out because of delayed
    ignition scenarios where, because the boiler is not running properly and is
    not set up properly, you could have delayed ignition of oil creating a puff
    that could push [the connector] out.’’
    6
    For instance, despite his general contention that he owed no duty, the
    defendant asserts in his brief that ‘‘it would appear to be against public
    policy to hold a gratuitous helper to the same standard of care as a skilled
    tradesman.’’ Indeed, at oral argument before this court, the defendant stated
    that part of his argument concerned the applicable standard of care for any
    duty that he might have owed in this case.
    7
    Depending on the particular statute, however, a statutory violation might
    not constitute negligence per se, but could establish a prima facie case of
    negligence or could provide evidence of negligence. See Ward v. Greene,
    
    267 Conn. 539
    , 548, 
    839 A.2d 1259
    (2004).
    8
    This potential class of persons may be quite broad. See Wright v. Brown,
    
    167 Conn. 464
    , 469, 
    356 A.2d 176
    (1975) (with respect to quarantine provisions
    of General Statutes § 22-358, ‘‘the class of persons protected is not limited;
    rather the statute was intended to protect the general public or, as stated
    by the trial court, members of the community’’ [internal quotation marks
    omitted]).
    9
    General Statutes § 20-330 (5) defines ‘‘heating, piping and cooling work’’
    as ‘‘(A) the installation, repair, replacement, maintenance or alteration of
    any apparatus for piping, appliances, devices or accessories for heating
    systems, including sheet metal work, (B) the installation, repair, replace-
    ment, maintenance or alteration of air conditioning and refrigeration sys-
    tems, boilers, including apparatus and piping for the generation or
    conveyance of steam and associated pumping equipment and process piping
    and the installation of tubing and piping mains and branch lines up to
    and including the closest valve to a machine or equipment used in the
    manufacturing process, but excluding millwright work, and (C) on-site oper-
    ation, by manipulating, adjusting or controlling, with sufficient technical
    knowledge, as determined by the commissioner, (i) heating systems with a
    steam or water boiler maximum operating pressure of fifteen pounds per
    square inch gauge or greater, or (ii) air conditioning or refrigeration systems
    with an aggregate of more than fifty horsepower or kilowatt equivalency of
    fifty horsepower or of two hundred pounds of refrigerant. . . .’’
    10
    This purpose is more apparent from the regulations defining the particu-
    lar licenses that may be issued by the Heating, Piping, Cooling, and Sheet
    Metal Work Board. See Regs., Conn. State Agencies § 20-332-5. Each of these
    licenses contain explicit limitations on who is able to acquire that license
    by defining the necessary training or experience required; see 
    id., § 20-332-
    5 (a) (examination for unlimited heating-cooling contractor’s license only
    available after ‘‘two (2) years as an unlimited licensed journeyperson or
    equivalent experience and training’’); or by limiting the type of projects on
    which, or the manner in which, the holder may work. See 
    id., § 20-332-
    5 (g)
    (limited heating contractor license allowed to work only on ‘‘hot water or
    steam heating systems for buildings not over three stories high with a total
    heating load not exceeding 500,000 BTU’s and steam pressure not exceeding
    fifteen pounds’’ as well as related gas systems and ‘‘oil burners handling
    up to five gallons per hour’’); see also 
    id., § 20-332-
    5 (j) (limited heating
    journeyperson may install, service, and repair gas or oil fired burners ‘‘only
    while in the employ of a contractor licensed for such work’’). To acquire a
    license, an individual must score at least 70 percent on the examination.
    
    Id., §§ 20-332-10a
    and 20-332-11a.
    11
    General Statutes § 42-110b (a) provides: ‘‘No person shall engage in
    unfair methods of competition and unfair or deceptive acts or practices in
    the conduct of any trade or commerce.’’ A cause of action may be brought
    by ‘‘[a]ny person who suffers any ascertainable loss of money or property,
    real or personal, as a result of the use or employment of a method, act or
    practice prohibited by section 42-110b.’’ General Statutes § 42-110g (a).
    12
    The attempt by the defendant to analogize his situation to that of a
    neighbor assisting a homeowner in installing a boiler in the latter’s home
    is not persuasive: unlike the actions of the defendant and his son here, the
    homeowner’s actions in the hypothetical at the very least could fall within
    an explicit exception to the licensure requirement. See General Statutes
    § 20-340 (11) (‘‘[t]he provisions of this chapter shall not apply to . . . per-
    sons engaged in the installation, maintenance, repair and service of glass
    or electrical, plumbing, fire protection sprinkler systems, solar, heating,
    piping, cooling and sheet metal equipment in and about single-family resi-
    dences owned and occupied or to be occupied by such persons; provided
    any such installation, maintenance and repair shall be subject to inspection
    and approval by the building official of the municipality in which such
    residence is located and shall conform to the requirements of the State
    Building Code’’).
    13
    In response to the questions of this court during oral argument, the
    defendant asserted that the purpose of the licensure statute was to protect
    the public from unscrupulous contractors. While true, it is not, however,
    the only purpose. See Hartford Hospital v. Dept. of Consumer 
    Protection, supra
    , 
    243 Conn. 719
    –20. Additionally, the defendant has not asserted on
    appeal that the failure to have the necessary occupational license is not a
    ground to assert a negligence per se claim because the failure to have that
    license was not the proximate cause of the fire.
    14
    The court stated that standards 31 and 211 were part of our state’s fire
    code. It did not explain, however, which portions of the fire code incorpo-
    rated these standards.
    We note that the provisions of our state fire safety code and our state
    fire prevention code generally do not apply to private single-family dwellings
    such as the property; see General Statutes § 29-292 (a) (1); Regs., Conn.
    State Agencies §§ 29-291a-1a (d) and 29-292-1e (b); and did not apply under
    the statutes and regulations in effect in 2011. See General Statutes (Rev. to
    2011) § 29-292 (a); Regs., Conn. State Agencies (Rev. to 2011) §§ 29-291a-1
    (d) (repealed May 7, 2015) and 29-292-1e (b) (amended effective October 2,
    2012). Other applicable statutes and regulations, however, contain materially
    similar requirements; see footnote 16 of this opinion; and the defendant has
    not challenged the court’s judgment on these grounds. See footnote 17 of
    this opinion.
    15
    Standard 31 provides in relevant part: ‘‘The chimney connector shall
    extend through a chimney wall to the inner face or liner but not beyond,
    and shall be firmly cemented to masonry. A thimble shall be permitted to
    be used to facilitate removal of the chimney connector for cleaning, in
    which case the thimble shall be permanently cemented in place with high-
    temperature cement.’’ National Fire Protection Assn., NFPA 31: Standard
    for the Installation of Oil-Burning Equipment (1992 Ed.) § 1-7.2.4, p. 31-12.
    Under the regulations in effect in 2011, this standard was incorporated by
    reference as our state’s regulations on the installation and operation of oil
    burning equipment; see Regs., Conn. State Agencies (Rev. to 2011) § 29-317-
    3a (a) (repealed May 7, 2015); and private residential dwellings are not
    excepted. See General Statutes (Rev. to 2011) § 29-317 (a) and (b); Regs.,
    Conn. State Agencies (Rev. to 2011) § 29-317-1a (b) and (d) (repealed May
    7, 2015). (Pursuant to amendments ultimately effective January 1, 2013,
    however; see Public Acts 2010, No. 10-54, §§ 1 and 6; Public Acts 2009,
    No. 09-177, § 7; regulations adopted pursuant to this authority are now
    incorporated into the state fire prevention code. See General Statutes § 29-
    317 [a].) Additionally, § 1805.2 of the 2003 International Code for One- and
    Two-Family Dwellings portion of the 2005 State Building Code provides in
    relevant part: ‘‘A connector entering a masonry chimney shall extend
    through, but not beyond the wall and shall be flush with the inner face of
    the liner. Connectors, or thimbles where used, shall be firmly cemented
    into the masonry.’’
    16
    The expert relied on standard 211 to address whether the concrete ring
    was a ‘‘thimble’’ as that term is used in standard 31. Standard 211 provides
    in relevant part: ‘‘Thimbles for chimneys or vent connectors shall be fireclay
    . . . galvanized steel of minimum thickness of 24 ga[u]ge, or material of
    equivalent durability. Thimbles shall be installed without damage to the
    liner. The thimble shall extend through the wall to, but not beyond, the
    inner face of the liner and shall be firmly cemented to masonry.’’ National
    Fire Protection Assn., NFPA 211: Standard for Chimneys, Fireplaces, Vents,
    and Solid Fuel-Burning Appliances (1992 Ed.) § 3-1.8.1, p. 211-18. Thus,
    because the clay ring was only two inches long and did not extend to the
    vertical flue, the expert explained, it was not a ‘‘thimble’’ as that term is
    used in standard 31. The defendant has not asserted on appeal that either
    the court’s reliance on this testimony or its application of the law was in error.
    17
    ‘‘In cases involving the doctrine of negligence per se . . . the defendant
    ordinarily may avoid liability upon proof of a valid excuse or justification.’’
    Gore v. People’s Savings Bank, 
    235 Conn. 360
    , 376, 
    665 A.2d 1341
    (1995),
    quoting 2 Restatement (Second), Torts § 288A (1965). The defendant, on
    appeal, has focused primarily on whether a duty existed and has not provided
    any separate argument that his failure to abide by either the licensure
    requirements or state building code was excused or justified.
    18
    ‘‘[O]ur threshold inquiry has always been whether the specific harm
    alleged by the plaintiff was foreseeable to the defendant. . . . By that is
    not meant that one charged with negligence must be found actually to have
    foreseen the probability of harm or that the particular injury which resulted
    was foreseeable, but the test is, would the ordinary [person] in the defen-
    dant’s position, knowing what he knew or should have known, anticipate
    that harm of the general nature of that suffered was likely to result? . . .
    The idea of risk in this context necessarily involves a recognizable danger,
    based upon some knowledge of the existing facts, and some reasonable
    belief that harm may possibly follow. . . . Accordingly, the fact finder must
    consider whether the defendant knew, or should have known, that the
    situation at hand would obviously and naturally, even though not necessarily,
    expose [the plaintiff] to probable injury unless preventive measures were
    taken.’’ (Internal quotation marks omitted.) Doe v. Hartford Roman Catholic
    Diocesan 
    Corp., supra

    317 Conn. 373

    We also note that the defendant has worked as a registered home
    improvement contractor for several decades.
    20
    Even if the court premised the defendant’s liability on his breach of a
    common-law duty to exercise reasonable care, the court would be permitted
    to rely on standards 31 and 211. To the extent that the defendant and his
    son were required to, and did, abide by these standards or similar statutes
    and regulations, compliance alone does not preclude liability for negligence.
    See Allison v. Manetta, 
    284 Conn. 389
    , 403, 
    933 A.2d 1197
    (2007) (‘‘[w]hile
    violation of a statute is negligence, compliance with a statute is not necessar-
    ily due care’’ [internal quotation marks omitted]); see also Josephson v.
    Meyers, 
    180 Conn. 302
    , 307–308, 
    429 A.2d 877
    (1980) (duty of care satisfied
    by complying with statute ‘‘where the facts are similar to those contemplated
    by the statute and no special or unusual circumstances or dangers are
    present’’). Alternatively, a court can consider a party’s failure to abide by
    even technically inapplicable statutes as evidence of negligence. See Consid-
    ine v. Waterbury, 
    279 Conn. 830
    , 860–69, 
    905 A.2d 70
    (2006) (failure to abide
    by building code provisions that were technically inapplicable to property
    because they were adopted after construction nonetheless may constitute
    evidence of failure to exercise due care).
    21
    The defendant also argues that public policy is against recognizing that
    he owed a duty in this case because ‘‘it would appear to be against public
    policy to hold a gratuitous helper to the same standard of care as a skilled
    tradesman.’’ He has offered no law or analysis in support of this contention,
    however, and we will not consider it. See Zappola v. Zappola, 159 Conn.
    App. 84, 86–87, 
    122 A.3d 267
    (2015).
    22
    For instance, the defendant provided the following summary of his and
    his son’s work: ‘‘We went there in the morning and disconnected the furnace
    and moved it out. And then they brought a new furnace. We moved it in.
    Got it repiped.’’ His son described their labors similarly.
    23
    Although the defendant testified that his position was wholly subservient
    to his son’s directions, both with respect to the general project and with
    respect to the particular act of constructing and installing the chimney
    connector, the court was not required to credit this testimony. See Burns
    v. 
    Adler, supra
    , 
    158 Conn. App. 802
