USPAP Standards and Appraisal Ethics: Rules, Conduct, and Discipline

The Uniform Standards of Professional Appraisal Practice, known as USPAP, are the baseline conduct and performance rules every appraiser in the United States must follow when developing and reporting an opinion of value. Federal law requires appraisals for federally related transactions to conform to USPAP, and residential real estate transactions above $400,000 generally trigger that requirement.¹ The current 2024 Edition, published by the Appraisal Standards Board of The Appraisal Foundation, operates on an open-ended model with no fixed expiration date and remains in effect until the Board adopts revisions.

The Financial Institutions Reform, Recovery, and Enforcement Act of 1989 gave USPAP its federal weight by directing every federal banking regulator to require USPAP compliance for appraisals in federally related transactions.² Transactions under the $400,000 residential threshold still require a value evaluation, but that evaluation does not have to come from a licensed appraiser or follow USPAP.³

The Ethics Rule

The Ethics Rule is the backbone of USPAP and governs four areas: conduct, management, confidentiality, and prior services disclosure. Its stated purpose is to promote and preserve public trust in appraisal practice.

Conduct

Every appraiser must perform assignments with impartiality, objectivity, and independence. Advocating for a party’s interest is prohibited, whether that party is the borrower hoping for a higher value or the lender trying to make the deal close. An appraiser cannot accept an assignment that calls for reporting a predetermined opinion of value, and performing an assignment with bias violates the rule regardless of intent.

Management

The management section targets financial incentives that can corrupt an appraisal. Compensation cannot be tied to the value conclusion, the direction of the result, the attainment of a loan amount, or any outcome linked to the assignment’s purpose. An appraiser who pays an undisclosed fee or commission to obtain work also violates this section. Any fee or commission paid in connection with procuring an assignment must be disclosed.

Confidentiality

Appraisers must protect the confidential nature of the appraiser-client relationship. Assignment results and confidential information cannot be shared with anyone other than the client, parties the client specifically authorizes, state enforcement agencies, or entities authorized through due process of law. Applicable privacy laws in the assignment’s jurisdiction apply on top of this.

Prior Services and Interest Disclosure

Before accepting an assignment, an appraiser must disclose any current or prospective interest in the subject property. The Ethics Rule also requires disclosure of any services the appraiser performed on the subject property within the three years immediately before accepting the assignment, whether those prior services were performed as an appraiser or in any other capacity. The signed certification in every report must confirm or specify these interests and prior services.

Nondiscrimination in Appraisals

The Ethics Rule prohibits appraisers from acting in any way that violates or contributes to a violation of federal, state, or local antidiscrimination laws. The reach is broader than avoiding slurs in a report. Using a seemingly neutral factor like neighborhood crime statistics as a pretext for race-based conclusions violates USPAP. Demographic data about protected characteristics, such as Census figures showing a neighborhood’s racial composition, counts as information relating to a protected characteristic and cannot be used in a residential assignment unless an explicit Fair Housing Act exception applies.⁴

The Foundation has warned specifically about artificial intelligence. An appraiser who relies on output from an automated tool or chatbot that incorporates discriminatory data can violate the nondiscrimination section without intending to discriminate.⁴

Enforcement sits with the Department of Justice, which brings Fair Housing Act cases over discriminatory residential valuations and has clarified that mortgage lenders can be held liable under the Fair Housing Act and Equal Credit Opportunity Act for relying on an appraisal they knew or should have known was discriminatory.⁵

Appraiser Independence and Pressure from Lenders

USPAP prohibits bias and predetermined results from the appraiser’s side. Federal consumer protection law adds a parallel prohibition aimed at everyone else. Regulation Z makes it illegal for any covered person to coerce, bribe, intimidate, or otherwise pressure an appraiser into reaching a particular value conclusion on a consumer’s principal dwelling.⁶ Prohibited conduct includes:

Telling the appraiser the value needs to come in at a minimum amount to make the loan work.
Refusing to pay the appraiser because the value came in below expectations.
Implying that future assignments depend on hitting certain value targets.
Removing an appraiser from a rotation because a prior report did not meet a predetermined threshold.
Making the appraiser’s compensation contingent on the transaction actually closing.

These protections extend to appraisal management companies, which coordinate most residential appraisal work today. Federal law requires AMCs to register with state regulators, verify that only licensed or certified appraisers handle federally related transactions, ensure USPAP compliance, and maintain appraisal independence free from inappropriate influence.⁷

The Competency Rule

The Competency Rule requires an appraiser to have the knowledge and experience necessary to complete an assignment competently before agreeing to take it on. Competency can involve a property type, a market, a geographic area, specific laws and regulations, or a particular analytical method. An appraiser comfortable with suburban single-family homes may lack the expertise for agricultural land or industrial property, and the rule requires them to recognize that gap.

When an appraiser lacks the required competency, they must either decline the assignment or disclose the deficiency to the client and take steps to close the gap. Those steps can include personal study, partnering with an appraiser who has the relevant expertise, or hiring someone with the necessary knowledge. The appraiser must actually achieve competency before delivering the final work product, not merely attempt to.

Geographic competency carries real weight. A residential appraiser unfamiliar with a particular market must acquire enough local knowledge to produce credible results for the specific property type involved. Misjudging local market conditions, missing a zoning change, or selecting inappropriate comparable sales from an unfamiliar area are the kinds of errors this rule exists to prevent.

The Scope of Work Rule

The Scope of Work Rule puts the responsibility on the appraiser to decide how much research and analysis a given assignment requires. The client does not dictate it. The appraiser identifies the problem, considers the intended use of the appraisal, and decides what data to gather and which valuation methods to apply. An acceptable scope must produce credible results and meet the expectations of other appraisers who regularly handle similar assignments.⁸

The rule cuts both directions. If an appraiser’s peers would have gathered certain data or applied a particular approach, skipping it undermines the report’s credibility. Running an exhaustive analysis when a more focused approach would do can waste the client’s time and money without producing a better result.

Hypothetical Conditions and Extraordinary Assumptions

Appraisals sometimes have to proceed on information that is either uncertain or known to be contrary to current facts. USPAP draws a line between the two. An extraordinary assumption involves uncertain information the appraiser treats as true for purposes of the analysis; if that assumption later proves wrong, the value conclusion could change. A hypothetical condition is something the appraiser knows is not currently true but assumes anyway, such as valuing a vacant lot as though a proposed building were already completed.

Both must be clearly and conspicuously disclosed in the report, not buried in an appendix. The report must state that the use of these conditions might have affected the assignment results. A hypothetical condition cannot be so far-fetched that it produces results no reasonable person would find credible.

Developing and Reporting the Appraisal

The appraisal work itself breaks into two phases. Standard 1 covers development of a real property appraisal, and Standard 2 covers reporting. Standards 3 and 4 govern appraisal review.⁹

Development

Standard 1 governs the analytical process behind the value opinion. The appraiser must identify the property’s physical and legal characteristics, including easements, encumbrances, and other restrictions that affect value. A central requirement is analyzing highest and best use: the appraiser must weigh the relevant legal, physical, and economic factors to determine what use of the property would produce the greatest value. The appraiser then selects and applies appropriate valuation approaches, such as the sales comparison, income, or cost approach, based on which methods the available data support.

Reporting and Certification

Standard 2 governs how the value opinion is communicated. Every written or oral report must clearly and accurately present the appraisal in a way that is not misleading. It must contain enough information for intended users to understand the rationale behind the final value, including a description of the property, the reasoning for the data selected, and the valuation methods applied.

Every report must include a signed certification. The certification is a series of sworn statements in which the appraiser affirms that the analysis was performed without bias, that the appraiser has no undisclosed interest in the property, and that the appraiser has or has not performed prior services on the property within the preceding three years. These statements expose the appraiser to liability if false, which is why experienced appraisers treat the certification as the most legally significant page in the report.

Record Keeping Requirements

Every appraiser must prepare and maintain a workfile for each assignment. The workfile is the physical or electronic evidence supporting the appraiser’s opinions and conclusions, and it must exist before any report is delivered to the client. Adding documentation to the workfile after the report has been sent is a violation.

The retention period is at least five years after the report is prepared, or at least two years after the final disposition of any judicial proceeding in which the appraiser provided testimony related to the assignment, whichever is longer. State regulators routinely audit workfiles, and an incomplete or missing workfile is one of the most common triggers for disciplinary action.

A digital copy of a report qualifies as a “true copy” under USPAP, but only if it is a complete replica of what the client received, including all addenda and the signed certification page. Internet-based data creates a particular trap. Web links go dead, and the appraiser remains responsible for being able to reproduce the specific data they relied on throughout the entire retention period. Saving a screenshot or PDF of online data at the time of the assignment is far safer than bookmarking a URL. Metadata matters too: a print date or file-creation date that postdates the report delivery can suggest documentation was assembled after the fact.

The Jurisdictional Exception Rule

USPAP applies nationally, but it occasionally conflicts with a state or local law. The Jurisdictional Exception Rule handles that collision. When a law or regulation precludes compliance with a specific part of USPAP, only that part becomes void for that particular assignment. The rest of USPAP still applies in full.

To invoke the exception, an appraiser must identify the specific law or regulation creating the conflict, comply with that law, and clearly disclose in the report which part of USPAP was voided along with the legal authority requiring the exception. Instructions from a client or attorney, customary local practice, published articles, or practices from other jurisdictions do not qualify. The exception exists strictly for binding legal authority.

Discipline for USPAP Violations

State appraiser regulatory agencies are the primary enforcement bodies for USPAP compliance. The Appraisal Subcommittee, the federal agency that oversees state programs, has published a disciplinary framework that categorizes violations into escalating levels, each carrying progressively heavier sanctions.¹⁰

Level I covers minor technical errors and typically results in a letter of warning, censure, corrective education, or a small fine.
Level II addresses carelessness that would benefit from education and can bring a formal reprimand, required coursework that cannot count toward renewal credits, short probation, monitoring, or a small to moderate fine.
Level III covers minor Ethics or Competency Rule violations and can bring a formal reprimand, required coursework, short suspension, medium probation, monitoring, or restrictions on the types of work the appraiser can perform.
Level IV and above covers serious violations and can bring significant suspension, longer probation, large fines, or outright revocation of the appraiser’s credential.

Revocation is generally permanent, though some states allow an appraiser with a revoked credential to reapply after a waiting period. States can also order restitution, requiring the appraiser to compensate anyone harmed by the work. Beyond state proceedings, an appraiser whose report contains material misrepresentations can face civil lawsuits for professional negligence and, in extreme cases, criminal prosecution for fraud.

If You Think an Appraisal Was Wrong

Borrowers who believe an appraisal undervalued their home have a formal path to challenge the result called a reconsideration of value, or ROV. Federal regulators have issued interagency guidance directing lenders to establish clear, accessible processes for consumers to raise valuation concerns early enough in underwriting for errors to be resolved before a final credit decision.¹¹

An ROV request works best when backed by specific, verifiable information the original appraiser may not have considered: comparable sales the appraiser missed, property features that were incorrectly reported, or recent improvements that were overlooked. The lender reviews the request and, if warranted, may ask the original appraiser to reconsider or order a second appraisal. The guidance also directs lenders not to create unreasonable barriers that discourage ROV requests.¹¹

Anyone who suspects an appraisal was influenced by racial or ethnic discrimination can report it to the Department of Justice at 1-833-591-0291 or by email at fairhousing@usdoj.gov.⁵
