- 02Check the condition that triggers UAD1164: AccessoryDwellingUnitIndicator is not provided in a given instance of PROPERTY_UNIT_DETAIL when STRUCTURE_DETAIL/LivingUnitCount > 0.
- 03Correct the missing, invalid, duplicate, or inconsistent value before submitting to UCDP.
- 04Use the official Single-family (SF1) sample value on this page as a reference pattern, then re-run validation.
