How to fix UAD1599
UAD1599 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.
- 01Open the Project Information › Units Rented area of the URAR and find Units Rented.
- 02Check the condition that triggers UAD1599: PropertyInProjectIndicator = "true" and ProjectDwellingUnitsRentedCount is not provided.
- 03Correct the missing, invalid, duplicate, or inconsistent value before submitting to UCDP.
- 04Use the official Condominium (Condo1) 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.
