How to fix UAD1166
UAD1166 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.
- 01Open the Unit Interior › Ingress/Egress area of the URAR and find Ingress/Egress.
- 02Check the condition that triggers UAD1166: AccessoryDwellingUnitIndicator = "true" and AccessType is not provided in a given instance of PROPERTY_UNIT_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.
