ASA is diligent in its efforts to ensure ethical practices and procedures on the part of its members. The Society has developed a mechanism for the enforcement of its Code of Ethics whereby clients may file an official, written complaint if they feel an appraisal rendered by an ASA member violates sound professional practice.

To file a complaint,  e-mail or mail your signed, written complaint to:
Attention: Chief Executive Officer
2121 Cooperative Way, Suite 210
Herndon, VA 20171

In July 2023, ASA's Board of Governors amended the Principles of Appraisal Practice and Code of Ethics to (1) reiterate to members that ASA’s Administrative Rules require compliance with USPAP or other relevant standards when performing an Appraisal or an Appraisal Review and (2) require members who are practicing outside of the United States and using other standards to include the following statement in any Appraisal report:

 “I hereby certify that, to the best of my knowledge and belief, the statements of fact contained in this report are true and correct, and this report has been prepared in conformity with the [applicable standards that were followed] and the Principles of Appraisal Practice and Code of Ethics of the American Society of Appraisers.”

ASA and more than 100 property professional bodies worldwide make up the International Ethics Standards Coalition (IESC), who believe that creating a universally applicable set of ethics values will help assert the role of ethics and help ensure greater professionalism. The group has published the first set of ethics principle for professionals working in land, property, construction, infrastructure, and related professions.
