AIA Code of Ethics: Canons, Ethical Standards, and Rules of Conduct

One-line orientation

The AIA Code of Ethics has three levels, from broad to specific:

1. Canons set the broad frame.
2. Ethical Standards state goals.
3. Rules of Conduct are mandatory and enforceable.

Key points

• Three-tier structure:
  • Canon — a broad category of conduct. The current AIA Code has six Canons; older editions may differ. A Canon does not by itself create an enforceable duty.
  • Ethical Standard — a specific goal that members “should” aspire to within a Canon. Aspirational, not mandatory; not directly enforceable.
  • Rules of Conduct — specific mandatory statements (“members shall / shall not”). These are enforceable. Violation triggers review by the National Ethics Council.
• Six Canon areas: General Obligations; Obligations to the Public; Obligations to the Client; Obligations to the Profession; Obligations to Colleagues; Obligations to the Environment.
• Selected Rules of Conduct to know:
  • Rule 1.101 — apply reasonable care and the competence ordinarily used by architects of good standing in the same locality (standard of care).
  • Rule 2.101 — an architect shall not violate the law while practicing architecture.
  • Rule 2.105 — Applies when an architect learns of an employer or client decision that violates law and will materially harm public safety in the finished project. The architect must then refuse consent, report the decision, or terminate services. Not a generic “known building code violation” duty.
  • Rule 4.101 — Requires an AIA member to file a complaint when substantial information supports a reasonable belief that another member seriously violated the Code. The concern must raise a serious question about that member’s honesty, trustworthiness, or fitness.
  • Rule 4.102 — prohibits stamping drawings when the architect was not in responsible control of their production (plan-stamping prohibition).
  • Rule 5.201 — AXP supervisors must assist supervised persons in gaining required AXP experience hours.
  • Rule 6.501 — members shall consider with their clients the environmental effects of their project decisions. (The specific factors — greenhouse-gas reduction, water conservation, climate-change adaptation — live in the aspirational Ethical Standards under Canon VI, not in the mandatory Rule itself.)
• Enforcement body: AIA’s National Ethics Council (a professional-society body, not government).
• Penalties (AIA only): admonition, censure, suspension, or termination of AIA membership. The AIA cannot revoke an architectural license.
• Scope: formally applies to AIA members; broadly treated as the profession-wide ethical standard.
