How to fix UAD1774
UAD1774 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.
- 01Open the Sales Comparison Approach › Dwelling(s) › Construction Method area of the URAR and find Construction Method.
- 02Check the condition that triggers UAD1774: @ValuationUseType = "SalesComparable" and ((ImprovementType = "Dwelling" and AttachmentType = "Detached") or (ImprovementType = "Dwelling" and AttachmentType = "Attached" and StructuralDesignType = "RowhouseTownhouse" or "SemiDetached" or "Other")), and (at least one instance of CONSTRUCTION_METHOD is not provided or ConstructionMethodType is not provided in a given instance of CONSTRUCTION_METHOD).
- 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.
