How to fix UAD1084

UAD1084 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.

01Open the Other area of the URAR and find LivingUnitCount.
02Check the condition that triggers UAD1084: ImprovementType = "Dwelling" or (ImprovementType = "Outbuilding" and OutbuildingRealPropertyIndicator = "true"), and LivingUnitCount is not provided in a given instance of STRUCTURE_DETAIL.
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.

This fix guidance is derived from the published rule message, trigger logic, report location, field definition, and official sample data available for this rule.
