Determine which USPAP Standards apply — mass appraisal vs. single-property appraisal

Steps

1. Confirm current USPAP numbering: Standards 1 and 2 govern development and reporting of a single real property appraisal; Standards 5 and 6 govern development and reporting of mass appraisals (e.g., ad valorem tax assessment).
2. Confirm which standard applies based on assignment type: mass appraisal (multiple properties valued as of a common date using a systematic, statistically tested approach) uses Standards 5/6; an individual property appraisal uses Standards 1/2.
3. Note that if a specific parcel cannot be credibly valued using the mass appraisal model within an otherwise mass-appraisal assignment, Standards 1/2 may need to apply to that parcel instead — document this determination.
4. Confirm the standard numbering against the current USPAP edition in use, since numbering could change in a future ASB revision.
5. Distinguish this from personal property appraisal standards (a different pair of Standards) if the assignment could be confused with that discipline.
