NCARB Model Rules of Conduct

The NCARB Model Rules of Conduct establish the mandatory professional conduct framework that state licensing boards use to regulate and discipline architects, centered on protecting public health, safety, and welfare through five core rule areas.

Overview

Every architect in the U.S. practices under rules that trace back to a single source: the NCARB Model Rules of Conduct. These aren't suggestions. They're the mandatory framework that state licensing boards adopt (in whole or with modifications) to regulate professional behavior and enforce discipline.

NCARB first developed these rules in 1975 and gained member board approval in June 1977. The latest revision dates to July 2023. The rules exist for one reason: protecting the public's health, safety, and welfare. Not advancing the profession. Not boosting architects' reputations. Public protection.

The five core rule areas cover competence, conflict of interest, full disclosure, compliance with laws, and signing and sealing documents. A sixth rule addresses further obligations to the profession and the public, including responsibilities for AXP supervisors.

Here's what catches candidates off guard on the ARE: these rules are mandatory and disciplinary, not aspirational. That distinction from professional association codes (like the AIA Code of Ethics) shows up in exam questions regularly. A violation can trigger suspension, revocation, reprimand, civil penalties, or restriction of your license. A single instance of misconduct is enough.

You also carry a duty that extends beyond your own practice. Architects must report known violations by other architects to their state board. That obligation isn't optional, and failing to report is itself a violation.

Essential

The NCARB Model Rules of Conduct form the backbone of professional regulation for architects across the United States. Understanding their structure, scope, and practical application is critical for the ARE and for your career. ## Origin and Purpose NCARB developed these rules starting in 1975 after studying conduct rules from various jurisdictions and other professions, interviewing government consumer affairs officials, and conducting extensive research. The first version was finalized in February 1977 and approved by member boards in June 1977. They've been revised multiple times since, with the most recent update in July 2023. The foundational principle: these rules protect the public, not the profession. That matters because it shapes everything about how they work. When your client's interests conflict with public safety, public safety wins. Always. Seven guiding principles underpin the rules. The ones that trip up candidates most often: - The rules are mandatory and disciplinary, not aspirational.

Professional

The NCARB Model Rules are straightforward on paper. In practice, they create situations where architects face genuinely difficult judgment calls. ## Scenario: The Client Who Won't Listen Consider an architect working on a commercial renovation who discovers that the client's preferred structural modification would violate the building code. The architect notifies the client, provides documentation, and recommends an alternative approach. The client insists on proceeding with the original plan because it's cheaper. Under Rule 1.2, the architect took the right first step by not knowingly designing in violation of building laws. But this scenario triggers Rule 3.5's three-step escalation. The architect must refuse to consent to the decision, then report to the building code enforcement official, and if the client appears likely to continue making similar decisions, terminate services on the project. That termination step creates real business consequences. Lost revenue. A potentially unhappy client who tells other potential clients.

TLDR

Mandatory, not aspirational. The Model Rules are enforceable disciplinary rules adopted by state boards. Violating them puts your license at risk. Professional association codes (like the AIA's) are aspirational. Know the difference.
Five core rules: (1) Competence, (2) Conflict of Interest, (3) Full Disclosure, (4) Compliance with Laws, (5) Signing and Sealing Documents. Rule 6 adds AXP supervisor obligations.
Public protection comes first. The rules exist to protect the public's health, safety, and welfare. When client interests conflict with public safety, the public wins. Period.
Rule 3.5 three-step escalation: If a client decision violates building code and endangers public safety: (1) refuse to consent, (2) report to enforcement official, (3) terminate services if the pattern continues.
You must report violations. Rule 3.9 requires you to report other architects' violations to the board. Self-reporting your own violations is also required under the Model Law. Both failures are separately disciplinable.
Conflicts of interest need written disclosure and waiver. No accepting supplier kickbacks for specifying products. Customary business hospitality is the exception, not the loophole.
Responsible control governs sealing. Only sign and seal documents prepared under your responsible control, with narrow exceptions for reviewed third-party information and jurisdiction-compliant prototypical documents.
Cross-jurisdiction consequences are real. Discipline in one state can trigger discipline in every other state where you hold a license. NCARB certificate holders face separate revocation proceedings.
Board discipline doesn't require a criminal conviction. The board can act independently of any court proceeding.
Firm leaders carry personal liability. Any architect in charge of a firm's practice is deemed to have violated the rules if the firm violates them.

ELI5

Think of the NCARB Model Rules of Conduct like the rules of the road for architects. Just as you need a driver's license and must follow traffic laws to drive, architects need a license and must follow these professional conduct rules to practice. The organization that created these rules is NCARB, which stands for the National Council of Architectural Registration Boards. They're the group that coordinates all 55 state and territory licensing boards across the U.S. They wrote a set of model rules that each state can adopt for their own licensing requirements. So what do the rules actually cover? Five main areas. Competence is about making sure you only take on work you're qualified to do. Imagine a doctor who specializes in dermatology performing brain surgery. That wouldn't be okay.
