Each state has its own set of appraiser regulations. Although there are substantial similarities, they can vary. The Appraisal Institute has assembled a document titled “Provisions of State Appraiser Licensing and Certification Laws Applicable to Appraisal Review” which is available free to its members and may be purchased by non-AI professionals. The document provides information on state agencies, definitions, certification and/or licensing requirements, as well as appraisal management company requirements.
