The Uniform Standards of Professional Appraisal Practice (USPAP) are the generally accepted standards for professional appraisal practice in North America. USPAP contains standards for all types of appraisal services. Standards are included for real estate, personal property, business and mass appraisal.
The Financial Institutions Reform, Recovery and Enforcement Act of 1989 recognizes USPAP as the generally accepted appraisal standards and requires USPAP compliance for appraisers in federally related transactions. State Appraiser Certification and Licensing Boards; federal, state, and local agencies, appraisal services; and appraisal trade associations require compliance with USPAP.
