    DIVISION FOUR
    GEORGE SIEG,
    Plaintiff and Appellant,
    A156089
    v.
    THE REGISTRAR OF                                                  (Sonoma County
    CONTRACTORS, CALIFORNIA                                           Super. Ct. No. SCV-261304)
    CONTRACTORS’ STATE LICENSE
    BOARD,
    Defendants and Respondents.
    George Sieg appeals from a judgment denying a petition for a writ of
    administrative mandamus by which he sought review of a disciplinary
    decision rendered against him by the Registrar of the California Contractors’
    State License Board (Registrar). Based on Sieg’s improper installation of
    hardwood flooring in a client’s home, which caused the client to incur
    considerable replacement and reinstallation expense, the Registrar found
    violations of Business and Professions Code1 sections 7109, subdivision (a),
    and 7113, and ordered payment of restitution, a three-year term of probation,
    and imposition of a disciplinary bond requirement. We affirm.
    All statutory references are to the Business & Professions Code,
    1
    unless otherwise specifically designated.
    1
    I. Procedural Background
    A. Administrative Proceedings
    An enforcement representative for the California Contractors’ State
    License Board (CSLB) filed an Accusation seeking revocation or suspension of
    Sieg’s contractor’s license and restitution. The Accusation alleged that Sieg,
    who does business as a sole proprietor under the name B & G Hardwood
    Flooring, failed to follow spacing and fastening requirements when installing
    a hardwood floor, thus subjecting his license to discipline for departing from
    trade standards in violation of section 7109, subdivision (a), and for failing to
    complete a construction project for the agreed contract price in violation of
    section 7113. Sieg filed a Notice of Defense requesting an administrative
    hearing, and shortly thereafter filed a civil lawsuit against the homeowners
    involved.2
    An Administrative Law Judge (ALJ) conducted an administrative
    hearing that was held over the course of two days. Following these two
    hearing days, the ALJ issued an order giving the CSLB an opportunity for a
    third day of hearing to put on a rebuttal case following the close of Sieg’s
    case-in-chief. Due to the illness of Sieg’s counsel, many months passed before
    that additional hearing day could take place. Eventually, the CSLB waived
    its right to present rebuttal evidence and sought leave to submit written
    closing argument. The ALJ granted its request, and the parties submitted
    written closing arguments.
    The ALJ then issued a proposed decision recommending a 65-day
    suspension and a three-year probation term including payment of restitution
    in the amount of $27,884.21. The Registrar adopted the ALJ’s proposed
    2In an earlier unpublished opinion (Sieg v. Torchia (July 31, 2019,
    A152750)), we affirmed the dismissal of the complaint in that action, Sieg v.
    Torchia (Super. Ct. Sonoma County, 2019, No. SCV-258043).

    decision but eliminated the 65-day suspension term and required Sieg to
    obtain a disciplinary bond of $30,000.00 under section 7071.8, effective for a
    period of three years.
    B. Administrative Mandamus Proceedings in Superior Court
    Sieg challenged the Registrar’s decision in Superior Court by filing a
    petition for a writ of administrative mandamus under Code of Civil
    Procedure section 1094.5. Following the filing of an amended petition, the
    trial court heard argument and issued an order denying writ relief. This
    timely appeal is from the judgment entered on that order
    II. Evidence Adduced at the Hearing Before the ALJ
    In mid-January 2012, Dennis Torchia (Torchia) and his wife Ana
    Torchia3 purchased from Lumber Liquidators a floor covering product known
    as Brazilian Ebony hardwood for their home in Windsor, California. Torchia
    chose Brazilian Ebony, an exotic species of unusually hard wood, for its
    appearance and durability. Sales personnel at Lumber Liquidators
    estimated the wood would be delivered within three to four weeks.
    For installation following delivery, Lumber Liquidators referred
    Torchia to its installation service department, Home Services Store (HSS),
    which in turn recommended Sieg to do the installation. Upon this
    recommendation, Torchia hired Sieg to install his new flooring. The initial
    meeting between contractor and client occurred January 23, 2012, when Sieg
    went to Torchia’s home to take measurements and provide an estimate for
    labor. Torchia testified that, during this meeting, he does not recall Sieg
    advising him to install a plastic cover over the crawl space dirt below his
    3 Because all of the pertinent interactions with Sieg and his homeowner
    clients, the Torchias as a couple, appear to have taken place between Sieg
    and Dennis Torchia, we will generally refer only to Dennis Torchia in this
    opinion. We mean no disrespect in doing so.
    3
    home as a barrier against moisture intrusion, and he was given no
    instructions about doing anything to prepare for the installation.
    Due to a product delivery delay well beyond the estimate Lumber
    Liquidators gave, several months passed between Sieg’s initial meeting with
    Torchia in mid-January and the delivery of the wood, which pushed the start
    date for the installation project into early summer 2012. Sometime around
    June 16, 2012, the Brazilian Ebony wood arrived at Lumber Liquidators, and
    Sieg and his crew delivered it to Torchia’s home a few days later. Sieg
    measured the moisture of the wood and informed Torchia that there was
    more than the allowed two points moisture difference between the existing
    subfloor and the new wood flooring, and therefore installation was scheduled
    for a week later, to allow time for the new wood to acclimate.4
    The evidence was conflicting as to when a contract to begin the project
    was signed. The day after the initial meeting between Sieg and Torchia in
    January 2012, Sieg gave Torchia a work order proposal estimating the costs
    of the job and attaching a document entitled “Conditions” that states, in part,
    “6 mil black polyethylene is recommended to cover 100% of the crawl space
    earth.” Torchia signed this document on June 25, 2012. At some point, Sieg
    also presented Torchia with a document entitled “Installation Order Form.”
    The Installation Order Form, which bears a difficult-to-decipher set of initials
    dated January 23, 2012, on a line signifying “Customer Initials,” has the
    word “Yes” written in after “MOISTURE BARRIER NEEDED,” and includes
    language at the bottom of the form stating “[t]he above information has been
    explained to me in full by my installer, and I understand that the installer,
    4“Points” in this context refers to moisture level as measured by a
    moisture meter. In in this case, the subfloor had more than two “points” of
    moisture compared to the Brazilian Ebony.
    4
    HSS and the HSS retailer are not responsible for any damage caused by post-
    installation changes in the moisture levels.”
    Torchia testified at the hearing that the manual dating and initialing
    as of January 23rd on the Installation Order Form was forged, that he did
    not sign it until after the wood arrived in June of 2012, and that he had no
    recollection of seeing it until then. Torchia acknowledged that, on June 25,
    2015, in a conversation about starting the project, Sieg raised the need for a
    moisture barrier, but he claimed that that was the first time Sieg brought up
    the topic. Torchia also acknowledged a felt-sense of urgency to begin the
    work. Sieg wanted to wait a few more days so that the wood would have even
    more time to acclimate; he stated that he would proceed with the installation
    immediately, so long as Torchia signed a disclaimer and release of any claims
    for problems arising from installation without a moisture barrier. Torchia
    assented on June 28, 2012, signing a document presented to him by Sieg
    entitled HSS Installation Disclaimer and Release (the Disclaimer).
    The Disclaimer states that installation of the floor was inadvisable
    because the “Prefinished flooring is over two points less than subfloor and no
    plastic covering the dirt under house.” Torchia testified that he felt
    pressured to sign the Disclaimer because he would be unable to take time off
    work to oversee the installation if the project did not start as scheduled.
    Sieg, he testified, assured him that proceeding without a moisture barrier
    most likely would not cause any problems and that some wood never
    technically acclimates—in essence, that things would be “fine.” According to
    Torchia, Sieg told him that, other than possibly putting the manufacturer’s
    warranty at risk, he felt it was okay to proceed.
    On June 29, 2012, Sieg and his workers began installation of the floor.
    The project took four days to complete. Within weeks of installation, Torchia
    noticed a “very loud popping sound, sounding like firecrackers going off in
    5
    different parts of the house.” Later investigation of these problems by a
    flooring inspection expert hired by Lumber Liquidators, Richard King,
    revealed that, in addition to the fact that the flooring had been installed
    without a plastic liner under circumstances in which there was a moisture
    differential between the wood and the subfloor, there were problems with the
    workmanship, including the following: (1) The flooring was installed tight
    against the walls, with no expansion space provided. (2) Some areas of the
    flooring had no fasteners. (3) The flooring was generally fastened two to four
    inches from ends, further than the manufacturer-required one to three inches
    from ends. (4) The flooring fasteners were generally spaced eight to eleven
    inches apart, in some places more than twelve inches apart, further than the
    manufacturer-required six to eight inches apart. (5) Fasteners were driven
    through the sub-floor. (6) No underlayment was installed around registers
    and crawl space access.
    King opined that these installation errors caused the problems Torchia
    was experiencing with his floor, and that Sieg’s workmanship did not comply
    with accepted trade standards for good and workmanlike construction. The
    lack of proper fastening, in particular, created a situation unlike any King
    had ever come across in his decades of experience: “[W]hen you walk on the
    floor and it’s not fastened properly, the floor moves, buckles, wiggles, makes
    noises. But with Mr. Torchia’s floor . . . I could look into the alcove with
    nobody in there. And the floor continued to pop and make noises. It was like
    it was demonized. . . . [¶] I also saw visually from floor level gaps between the
    edges of the planks, I could see the tongue side of the board. And I found
    boards that had no fasteners in there, let alone not being spaced properly,
    which would indicate the reason why the floor moves and buckles.” Sieg
    admitted he had not followed manufacturer instructions for edge spacing and
    fastener spacing.
    6
    Torchia testified that, upon reporting these problems to Sieg, Sieg was
    dismissive and unresponsive. Acting on his own, Torchia tried to take steps
    to rectify the issues he was experiencing, but the process of finding someone
    to assist was difficult, drawn out, and expensive. At a cost of about $7,000,
    sometime around April of 2013 Torchia had the crawl space encapsulated
    with a liner, a measure he took in an effort to reduce humidity and moisture.
    Even after putting in a moisture barrier, however, he continued to experience
    problems with the flooring.
    In July of 2014, two years after installation of the floor, Torchia finally
    found another flooring contractor, Michael Roesner, to diagnose the problems
    and propose a remedial plan. Roesner provided a proposal to repair the floor
    by removing and reinstalling it. He testified at the hearing: “[I]t was evident
    when I walked in . . . there was already some noticeable things with the floor
    . . . [¶] buckling, tenting,5 and some crackling noises as we were walking over
    it.” Roesner opined that improper expansion space and improper fastening
    spaces contributed to the problems with the floor. His proposal for the labor
    to correct the installation did not include the cost of 35 percent of the wood
    that he estimated could not be salvaged and would have to be replaced.
    Based on Roesner’s proposal and the price that the homeowner had paid for
    the wood, CSLB investigator Oather McClung, Jr. calculated that Torchia
    would have to pay approximately $27,884.21 above the contract price in order
    to have the project corrected.
    As of the date of Torchia’s testimony before the ALJ several years later,
    Torchia had not yet hired anyone to carry out the removal and reinstallation,
    but still hoped to have it done: “I had a difficult time finding someone who
    5“Tenting” in hardwood flooring is a condition where the floorboards
    have raised edges.
    7
    would actually give me an estimate to repair it. . . . I finally found someone
    who would give me an estimate, and the estimate is actually more expensive
    than it was to install the first floor, including the product and the installation
    for costs. . . . [¶] I had hoped [to get it repaired] a long time ago, but obviously
    this has been a long, drawn out process.” It had been more than three years
    since Torchia had the plastic liner installed over the crawl space, and not
    only had there been no improvement to the loud, cracking noises, but Torchia
    could also feel the flooring moving underneath his feet, and edges of some of
    the boards were still raised.
    In response, Sieg pointed out that Roesner, whom Sieg characterized as
    “the only competent Bay Area flooring contractor to testify,” had nothing
    negative to say about his workmanship. And by way of affirmative rebuttal
    to CSLB’s case, he offered the expert testimony of another flooring contractor,
    John Karriker, who opined that the post-installation problems that developed
    with Torchia’s flooring were a result of moisture vapor intrusion into the
    floors. Karriker disagreed with King’s view that there were workmanship
    problems with the installation, such as incorrect placement of fasteners and
    inadequate perimeter expansion spacing.
    Based on Karriker’s testimony as well as his own, Sieg’s defense
    centered on an argument that the sole problem with the installation of
    Torchia’s flooring was moisture intrusion, which caused cupping in the
    hardwood boards. According to Sieg, Torchia brought that problem on
    himself. Pointing to Torchia’s experience with releases in his job in the
    insurance industry, Sieg argued that Torchia was a sophisticated consumer
    who signed the Disclaimer knowing the risk of proceeding without a liner, yet
    he decided to do so anyway because any delay beyond June 2012 would have
    interfered with his vacation plans.
    8
    III. Decisions by the ALJ and by the Trial Court
    The ALJ upheld the CSLB’s Accusation in its entirety, finding the
    charges established by clear and convincing proof. In his decision, the ALJ
    left no doubt whom he believed and whom he did not. Making specific
    credibility findings in favor of Torchia, King, Roesner and McClung, and
    specific adverse credibility findings against Sieg and Karriker, the ALJ found
    that Torchia had been inadequately advised of the risks of installation
    without a plastic liner; that there were multiple workmanship problems with
    the installation in addition to the absence of a liner; and that the Disclaimer
    was void and unenforceable. The ALJ also made specific findings that Sieg
    gave false and misleading information to CSLB’s investigators, and that Sieg
    “refused to reasonably respond to the reasonable and earnest” complaints
    from Torchia or to make him financially whole.
    The trial court, on review of the Registrar’s decision adopting the ALJ’s
    decision in modified form, ruled as follows. First, the court sustained the
    CSLB’s objections to evidence presented by Sieg on the ground that none of
    the proffered evidence was presented at the hearing before the ALJ. In
    support of his request for mandamus relief, Sieg attempted to introduce a
    variety of evidence that had not been considered by the ALJ, including a
    September 2016 additional report by King as to the causes of the problems
    with Torchia’s floor, and certain testimony given in the course of Sieg’s
    lawsuit against the Torchias. The court explained that it must base its
    decision in a mandamus review proceeding on the evidence that was made
    part of the administrative record.
    Second, applying the independent judgment test under which factual
    findings supported by the administrative agency are affirmed if supported by
    the weight of the evidence, the court upheld the ALJ’s determinations that
    Sieg committed numerous workmanship violations. The court specifically
    9
    found King’s testimony to have been credible. The court also took into
    account the favorable credibility determinations of the ALJ with respect to
    Roesner, McClung, and Torchia and the adverse credibility determinations
    with respect to Sieg and Karriker. Based on these findings, and in reliance
    on Mickelson Concrete Co. v. Contractors’ State License Board (1979)
    
    95 Cal. App. 3d 631
    (Mickelson), the court affirmed the CSLB’s conclusions
    that Sieg willfully deviated from accepted standards for good and
    workmanlike construction and failed to complete a project he had contracted
    to undertake for the agreed contract price.
    Third, the court rejected Sieg’s defense based on the Disclaimer. The
    court concluded that “[t]he evidence from the record demonstrates that [Sieg]
    was in a superior position to the homeowner in understanding the proper
    steps and requirements when installing a floor”; that Sieg “had decades of
    experience and knowledge and was a licensed contractor”; and that “[t]he
    weight of the evidence established that [Sieg] failed to SUFFICIENTLY
    advise the homeowner that a plastic cover was needed in the crawl space.”
    Based on these findings, the court affirmed the CSLB’s conclusions that the
    Disclaimer was void as an invalid waiver of statutory standards of
    workmanship and unenforceable as an unconscionable contract.
    Finally, the court rejected Sieg’s contention that the manner in which
    the ALJ conducted the hearing violated his due process rights. As explained
    by the trial court, “the Administrative Law Judge took great care and
    extended significant efforts to ensure [Sieg] received a fair and complete
    hearing. The ALJ was patient and took steps to give all parties the
    opportunity to present their cases. This included ongoing opportunities for
    [Sieg] to provide evidence both in person and in writing. The ALJ was fair in
    taking into consideration the availability of [Sieg’s] counsel while he
    addressed important health issues. The record establishes that the ALJ was
    10
    flexible on scheduling and reasonable in the manner in which he conducted
    the hearing.”
    IV. Discussion
    A. Standards of Review
    Upon review of an administrative decision in a professional licensing
    discipline proceeding by petition for a writ of mandamus under Code of Civil
    Procedure section 1094.5, the trial court looks at the entire administrative
    record and makes its own determination (Fukuda v. City of Angels (1999)
    
    20 Cal. 4th 805
    , 811–812 (Fukuda), applying what is known as the
    independent judgment test to both the facts and the law. (Ibid.) Under that
    test, the court will affirm agency findings of fact if they are supported by the
    weight of the evidence (Kazensky v. City of Merced (1998) 
    65 Cal. App. 4th 44
    ,
    51–52), but reviews questions of law de novo, giving respectful consideration
    to an agency’s decision on legal questions to the extent its reasoning is
    persuasive. (Szold v. Medical Bd. of California (2005) 
    127 Cal. App. 4th 591
    ,
    596 & fn. 4, citing Yamaha Corp. of America v. State Bd. of Equalization
    (1998) 
    19 Cal. 4th 1
    , 7–8 (Yamaha).
    In the trial court’s assessment of facts on mandamus review,
    “ ‘independent judgment’ review” does not mean “ ‘the preliminary work
    performed by the administrative board in sifting the evidence and in making
    its findings is wasted effort. . . . [I]n weighing the evidence the courts can and
    should be assisted by the findings of the board. The findings of the board
    come before the court with a strong presumption of their correctness, and the
    burden rests on the complaining party to convince the court that the board’s
    decision is contrary to the weight of the evidence.’ ” 
    (Fukuda, supra
    ,
    20 Cal.4th at pp. 811–812, italics omitted.)
    Then, in this court, on review of the trial court’s decision in an
    administrative mandamus proceeding, “[o]rdinarily, we review the trial
    11
    court’s ruling for substantial evidence 
    (Fukuda, supra
    , [20 Cal.4th] at p. 824),
    but [as in the trial court] we review de novo rulings on questions of law such
    as interpretation of city charters and municipal codes” (Szold, at 596 & fn. 4;
    Hall-Villareal v. City of Fresno (2011) 
    196 Cal. App. 4th 24
    , 29) and other
    matters resting on undisputed facts, giving deference under Yamaha to the
    degree the agency’s decision is persuasive. 
    (Yamaha, supra
    , 
    19 Cal. 4th 1
    ,
    7–8.) Under this standard, our task in this case is to evaluate the entire
    record, interpreting the evidence in the light most favorable to the CSLB and
    drawing all reasonable inferences in its favor, as the CSLB was the
    prevailing party in the lower court. (Diego v. City of Los Angeles (2017)
    
    15 Cal. App. 5th 338
    , 349.) Sieg, as the appellant, bears the burden of
    affirmatively demonstrating error. (Culbertson v. R. D. Werner Co., Inc.
    (1987) 
    190 Cal. App. 3d 704
    .)
    We cannot substitute our view of the evidence for that of the trial court.
    “So long as there is ‘substantial evidence,’ [we] must affirm, even if [we]
    would have ruled differently had [we] presided over the proceedings below,
    and even if other substantial evidence would have supported a different
    result.” (Major v. Western Home Ins. Co. (2009) 
    169 Cal. App. 4th 1197
    , 1208;
    Bowers v. Bernards (1984) 
    150 Cal. App. 3d 870
    , 874.) Substantial evidence
    means “evidence . . . ‘of ponderable legal significance, [which is] reasonable in
    nature, credible, and of solid value.’ ” A single witness’ testimony may be
    sufficient to satisfy the substantial evidence test. (
    Mickelson, supra
    ,
    95 Cal.App.3d at p. 634.) If more than one rational inference can be deduced
    from the facts, we may not replace the trial court’s conclusions with our own.
    (Tellis v. Contractors’ State License Bd. (2000) 
    79 Cal. App. 4th 153
    , 158
    (Tellis).)
    Applying the foregoing principles of review, we conclude that Sieg has
    not borne his burden of demonstrating error. We are satisfied that the trial
    12
    court’s factual findings are supported by substantial evidence and we see no
    error in its legal conclusions.
    B. Violation of Substandard Work (§ 7109, subd. (a)) and Failure
    To Complete Contracted Work at Agreed Price (§ 7113) Provisions of the
    Contractors’ State License Law
    Chapter 9, Article 7 of the Contractors’ State License Law (§ 7000 et
    seq.) governs contractor disciplinary actions against contractors. 
    (Tellis, supra
    , 79 Cal.App.4th at p. 158.) Among the grounds for discipline under
    that chapter are those set forth in section 7109, subdivision (a), which applies
    to any “willful departure in any material respect from accepted trade
    standards for good and workmanlike construction . . . unless the departure
    was in accordance with plans and specifications prepared by or under the
    direct supervision of an architect[,]” and section 7113, which applies to any
    “[f]ailure in a material respect on the part of a licensee to complete any
    construction project or operation for the price stated in the contract for such
    construction project or operation or in any modification of such contract[.]”
    The elements of a section 7109 violation are not identical to the
    elements of a section 7113 violation, and a violation of section 7109,
    subdivision (a) does not necessarily compel the conclusion there was a
    violation of section 7113. But where, factually—as in this case, given the
    persistent nature of Torchia’s floor problems, and Sieg’s failure to address
    them—it is alleged that “a contractor’s failure to take corrective action to
    make an ostensibly completed construction project an acceptable one that
    met trade standards” (Viking Pools, Inc. v. Maloney (1989) 
    48 Cal. 3d 602
    ,
    608), the violation of section of 7113 is tantamount to a lesser included
    offense within the broader ambit of section 7109, subdivision (a). Sieg does
    not argue otherwise. Our resolution of this appeal therefore turns on
    13
    whether facts and the law support the determination that Sieg violated
    section 7109, subdivision (a).
    1. Substantial Evidence Supports the Adjudicated Disciplinary
    Violations
    We conclude the evidence is sufficient to support the finding that Sieg
    willfully departed from accepted trade standards for good and workmanlike
    construction in violation of section 7109, subdivision (a), starting with the
    “buckling, tenting, and. . . crackling noises” observed by Roesner in 2014. To
    explain those conditions, King testified that, among other things, Sieg failed
    to leave adequate expansion space for the wood, failed to follow manufacturer
    and other requirements regarding fastening the wood, and failed to include
    an underlayment under the complete floor, and that these violations, at a
    minimum, contributed to the problems with the floor.
    The workmanship deficiencies King identified in Sieg’s installation
    included violation of the manufacturer’s recommended standard for “exotic
    species,” which required a consistent “nailing schedule” placing nails between
    six and eight inches apart. This failing was consistent with CSLB
    investigator McLung’s observation that Sieg’s lack of familiarity with such a
    rare wood made it all the more important that he strictly follow
    manufacturer instructions. There was also evidence that the problems with
    Sieg’s installation persisted for years. According to Torchia, at the time of
    the hearing, three years after installation, even after he installed a plastic
    liner over the crawl space, the floor still moved when walked upon, had
    tented boards, and emitted loud, cracking noises at random.
    We acknowledge that Sieg firmly disagrees. Emphasizing his 30-year
    discipline-free record as a contractor until this case arose, Sieg argues that
    the problems with the floor were not caused by the workmanship violations
    described above. He contends that what caused these problems was moisture
    14
    coming from the crawl space, which needed a plastic cover over the soil, as he
    repeatedly warned Torchia before the installation began. But this is nothing
    more than an effort to reargue the evidence on appeal. Sieg’s contention that
    Torchia knowingly decided to proceed, having been advised of the risks of an
    installation without a moisture barrier, turns on the factual premise—
    presented by his expert, Karriker—that moisture intrusion was the sole
    cause of the problems Torchia later experienced. Resolving what was
    essentially a battle between experts, the ALJ decided this issue against Sieg,
    and the trial court upheld that decision, employing its independent judgment.
    We cannot revisit these matters here. What is dispositive, at this stage, is
    that the record contains substantial evidence to support Torchia’s side of the
    dispute.
    Sieg makes the fallback argument that there is insufficient evidence to
    support a finding that he acted willfully, a necessary component of discipline
    based on a departure from accepted trade standards under section 7109,
    subdivision (a). We are not persuaded. There is ample evidence to support a
    willfulness determination under the general intent standard of willful in
    section 7109. 
    Mickelson, supra
    , 95 Cal. App. 3d at p. 635, cited by the trial
    court, makes clear that section 7109’s willfulness requirement is satisfied by
    evidence of a general intent to act. “ ‘In civil cases, the word “willful,” as
    ordinarily used in courts of law, does not necessarily imply anything
    blamable, or any malice or wrong toward the other party, or perverseness or
    moral delinquency, but merely that the thing done or omitted to be done was
    done or omitted intentionally. It amounts to nothing more than this: That
    the person knows what he is doing, intends to do what he is doing, and is a
    free agent.’ ” (Suman v. BMW of North America, Inc. (1994)
    
    23 Cal. App. 4th 1
    , 12; see Murrill v. State Board of Accountancy (1950)
    
    97 Cal. App. 2d 709
    , 713; Milner v. Fox (1980) 
    102 Cal. App. 3d 567
    , 573 fn. 9.)

    2. A Private Agreement To Dilute, Circumvent, or Release Away
    Statutorily Imposed Workmanship Standards Provides No Defense
    in Disciplinary Proceedings Under the Contractors’ Licensing Law
    Sieg lays great emphasis upon the argument, made before the ALJ,
    made again in the trial court—and rejected both factually and legally at each
    stage—that in the Disclaimer Torchia released away any basis to complain
    about Sieg’s having installed the flooring without a moisture barrier in place.
    He insists this case must be resolved for him as a matter of law by simply
    enforcing the Disclaimer according to its plain terms. We do not agree.
    Wholly aside from the fact that, here too, Sieg’s contentions reprise his side of
    a credibility contest (this one over when and under what circumstances he
    provided notice to Torchia about the need for a barrier), he misses the
    fundamental point the trial court made with its capitalization of the word
    “SUFFICIENTLY” in its order denying writ relief. The issue here is not that
    Sieg failed to apprise Torchia of the risks of proceeding with a moisture
    barrier, orally and in writing—including in the Disclaimer. It is that Sieg,
    who was in a superior position of knowledge and expertise, failed to apprise
    Torchia adequately of the risks.
    Legally, Sieg frames his Disclaimer argument on the premise that the
    error here is erroneous application of the unconscionability standard
    enunciated in Armendariz v. Foundation Health Psychcare Services, Inc.
    (2000) 
    24 Cal. 4th 83
    . As a statutory limitation on the enforceability of
    private contracts (Civ. Code § 1670.5), unconscionability requires a showing
    of both procedural and substantive unconscionability. (Armendariz, at
    p. 114.) Such a defense to enforcement of a contract may be defeated in
    circumstances where the consumer had genuine freedom of choice. (Freeman
    v. Wal-Mart Stores, Inc. (2003) 
    111 Cal. App. 4th 660
    , 669–670.) Arguing that
    the Armendariz standard cannot be met on this record, Sieg highlights
    16
    Torchia’s familiarity with releases and contends Torchia had options, but
    says “[i]t is clear that he wished to push forward with the project and was
    willing to assume any risks attendant [to it].” According to Sieg, the Torchias
    “insisted on the immediate installation convenient to their vacation schedule,
    ignoring or discounting the potential moisture issue warnings[.] [Sieg] was
    simply following the Torchias’ insistence on doing things ‘their way.’ ”
    Here again Sieg misses what we view as the dispositive point. Both the
    ALJ and the trial court rejected Sieg’s Disclaimer argument on two grounds,
    concluding that the Disclaimer is unenforceable as an illegal contract, quite
    apart from whether Torchia was a sophisticated consumer or had meaningful
    freedom of choice. We arrive at the same result, but on a slightly different
    ground than the ones the trial court and the ALJ articulated. Because this is
    not a private action between Sieg and Torchia, we see no need to address
    matters of unconscionability or contract illegality. Whether the Disclaimer
    was valid and enforceable as a contract is beside the point, since we are
    dealing with a disciplinary enforcement proceeding brought by CSLB on
    behalf of the public. For purposes of licensing enforcement, a homeowner
    cannot consent to a contractor’s departure from accepted trade standards for
    good and workmanlike construction. (Civ. Code § 3513 [a law established for
    a public reason cannot be contravened by a private agreement].)
    Whatever private arrangements may be made between a contractor
    and a client, the contractor has an independent obligation to the public to
    adhere to statutorily established standards of performance. (§ 7109,
    subd. (a); cf. 
    Mickelson, supra
    , 95 Cal.App.3d at p. 635 [rejecting concrete
    contractor’s attempt to defeat willfulness finding in section 7109 enforcement
    proceeding on the ground that “he informed both [clients] that a pour over
    was an improper method of repair, that he read [to the clients] the contents of
    the contract absolving himself of responsibility before proceeding with the
    17
    pour over”].) We base this reading of section 7109, subdivision (a), on the text
    and legislative history of the statute. As the CSLB correctly points out, the
    Legislature amended section 7109, subdivision (a), in 1988, to remove
    language which once made it possible for contractors facing discipline to
    defend accusations of departure from statutory trade standards by arguing
    client consent. (§ 7109, as amended by Stats. 1988, ch. 1619, § 4.) Thus,
    while the governing contract here established the benchmark for Sieg’s
    obligations to Torchia, in discharging those obligations he was bound to
    adhere to statutorily imposed standards of workmanship that could not be
    diluted, circumvented, or released away by private consent.
    C. Sieg Was Afforded Due Process Protections
    Sieg’s briefs are laced with florid innuendo suggesting that the
    Registrar’s disciplinary process is somehow corrupt6 and that the ALJ was
    biased against him.7 Despite the heated rhetoric, we discern few specifics
    and even less substance to these undifferentiated claims of procedural
    unfairness. Sieg failed to present any such attacks on the integrity of the
    administrative process to the trial court—at least not in a sufficiently specific
    6 See e.g., AOB at p. 12 (“The Registrar, a political Appointee, has, like
    all bureaucratic Managers an agenda and constituency. The Registrar is not
    and does not exercise a ‘Judicial’ function, it is prosecutorial. And, not only
    does it enforce its own agenda when it wishes, it imposes the entire cost of
    enforcement on the on the [sic] unfortunate focus of its prosecution. In
    Russia, the family of disfavored political figures similarly receives the bill for
    the cost of the executioner’s bullet.”)
    7 See AOB at p. 13 (“The Registrar has no ethical or internal
    institutional constraints. That is, the Registrar does not take a Judicial Oath
    and may or may not even have any legal training. [¶] . . . The Prosecution
    selects which OAH Hearing Officer will take the CSLB’s evidence. Here,
    Hon. Perry Johnson ALJ, selected by the prosecuting attorney CSLB attorney
    [sic] who[m] it is also undisputed, so warned Sieg’s counsel, this ALJ had
    NEVER recommended contrary to her/CSLB desired result.”)
    18
    way to preserve them for argument on appeal, framed as a basis for relief in
    his writ petition—and, as a result, his broad-sweeping claims of corruption
    and bias have been forfeited in this court. We therefore will not address
    them.
    Beyond his generalized claims that the administrative process was
    stacked against him, we conclude that the specific complaints about
    procedural unfairness that Sieg did preserve for appellate review are
    meritless. Sieg complains, for example, of a series of “patently manifest” due
    process violations, chiefly “[t]he truncated time allowed [Sieg’s] counsel at the
    hearing,” which purportedly “precluded a thorough examination of the
    evidence.” He also complains about having been given an inadequate
    opportunity to cross-examine witnesses and about an “obvious” attempt by
    the ALJ to “cure” an omission in the CSLB’s proof by sua sponte inviting it to
    reopen its case after the second day of hearing, while at the same time
    rejecting Sieg’s effort to add evidence after the second day of hearing.
    On the basis of the record of the administrative proceedings, we reject
    Sieg’s claims of fundamental unfairness. In a multi-day hearing Sieg had
    ample opportunity to call and examine witnesses. Not only did Sieg have the
    opportunity to cross-examine each of the CSLB’s witnesses, he also had the
    opportunity to present witnesses of his own, and to testify on his own behalf.
    The CSLB was within its discretion to decline to receive additional evidence
    from Sieg after he rested his defense case at the end of the second day of the
    hearing. And after the hearing, Sieg exercised his right to submit written
    arguments, filing not one but two sets of written closings. Under the
    circumstances, the idea that he was not afforded sufficient opportunity to
    defend himself (Petrus v. Department of Motor Vehicles (2011)
    
    194 Cal. App. 4th 1240
    , 1245) is wholly unsustainable.
    19
    We also reject Sieg’s claim of unfairness based on events that occurred
    after the two days of hearing before the ALJ. In support of his writ petition,
    Sieg asked that the trial court review evidence obtained after the final day of
    hearing. He proffered the post-hearing evidence that the ALJ had excluded:
    a post-hearing report prepared by King, as well as excerpts of testimony from
    the civil trial in Sieg’s lawsuit against the Torchias. Sieg contended that
    these items of evidence contradicted or undermined testimony given by King
    and by Torchia at the administrative hearing. This effort to present
    additional, extra-record evidence was the subject of the initial evidentiary
    rulings in the trial court’s order denying writ relief.
    “As a general rule, a hearing on a writ of administrative mandamus is
    conducted solely on the record of the proceeding before the administrative
    agency. Code of Civil Procedure section 1094.5, subdivision (e), however,
    allows the trial court to consider evidence not presented at the administrative
    hearing if the evidence addresses the petitioner's claim that he or she was
    denied due process or a fair hearing.” (Richardson v. City and County of San
    Francisco Police Com. (2013) 
    214 Cal. App. 4th 671
    , 702 (Richardson); see
    Morongo Band of Mission Indians v. State Water Resources Control Bd.
    (2009) 
    45 Cal. 4th 731
    , 735, [in opposition to respondent’s writ petition in the
    superior court, agency submitted a declaration describing the agency’s
    internal structure and operating procedures].) “But the trial court may only
    admit relevant evidence that, in the exercise of reasonable diligence, could
    not have been produced at the administrative hearing.” 
    (Richardson, supra
    ,
    at p. 702.)
    Sieg claims the post-hearing evidence he proffered was unavailable at
    the time of the hearing and was relevant to his due process claims. With
    regard to King, Sieg contends the exhibit admitted into evidence before the
    ALJ purportedly as King’s expert “report” was not, in fact, a report authored
    20
    by King, but was instead a document prepared by the CSLB’s investigator,
    McClung. According to Sieg, in September 2016, King prepared an actual
    report for McClung in which he opined that the cupping of the hardwood in
    Torchia’s floor was caused by moisture problems—which is consistent with
    what Karriker opined. With respect to Torchia, Sieg claims there is now
    clear evidence of “perjury” by Torchia based on testimony given by Torchia in
    the course of Sieg’s lawsuit against him and his wife (before it was dismissed)
    in which Torchia admitted to receiving Sieg’s proposed contract in January
    2012 and acknowledged his expectation that Sieg would proceed with the
    flooring installation in June 2012 in reliance on the Disclaimer.
    We need not decide whether it was error to exclude any of this evidence
    under the Richardson standard, because even assuming it was, we think the
    error was harmless. To begin with, we have examined the September 2016
    expert report prepared by King and we are not persuaded that it contradicts
    his testimony at the hearing before the ALJ. King never testified that
    moisture was not a cause of the cupping problems with Torchia’s flooring; he
    testified it was among the causes. There is no reason to believe the outcome
    would have been any different had the ALJ considered Sieg’s proffered post-
    hearing evidence or used it as the basis for reopening the evidence to allow
    further cross-examination of King. Moreover, even assuming Karriker was
    correct, factually, about moisture as the sole cause of the post-installation
    problems Torchia experienced, that was simply the predicate for the
    argument that Torchia released Sieg from any legal exposure by signing the
    Disclaimer. As we have explained, however, the Disclaimer argument fails
    because private agreements to depart from statutorily imposed workmanship
    standards provide no defense to an alleged violation of section 7109,
    subdivision (a), in disciplinary enforcement proceedings. The rejection of
    Sieg’s attempt to introduce an admission from Torchia concerning his receipt
    21
    of other written warnings about proceeding with installation absent a
    moisture barrier is harmless for the same reason.

    The judgment is affirmed. Respondents to recover costs on appeal.
