UAD1420

FATAL

Official message text · Appendix H-1: UAD Compliance Rules — URAR, v1.5

Provide the interior quality rating.

Fatal — a single unresolved Fatal makes the entire submission come back NOT SUCCESSFUL (UCDP Hard Stop 401).

What triggers UAD1420

The published rule logic, verbatim:

If @ValuationUseType = "SalesComparable" and (ImprovementType = "Dwelling" OR (ImprovementType = "Outbuilding" and OutbuildingRealPropertyIndicator = "true" and AccessoryDwellingUnitIndicator = "true")), and InteriorQualityRatingCode is not provided in a given instance of PROPERTY_UNIT_DETAIL

• Checked for every Sales Comparable in the report.
• Bound to MISMO data point InteriorQualityRatingCode at ../VALUATION_ANALYSIS/PROPERTIES/PROPERTY/IMPROVEMENTS/IMPROVEMENT/PROPERTY_UNITS/PROPERTY_UNIT/PROPERTY_UNIT_DETAIL/

How to fix it

On the URAR, this lives at: Sales Comparison Approach → Interior Quality and Condition; ADU Interior Quality and Condition → Quality. Complete or correct that field in your form software, regenerate the package, and re-check before submission.

Because this is a Fatal edit, do not submit until it is resolved — one Fatal bounces the whole package.

UAD1420 is in UADCheck's reference library; automated coverage for it is on the roadmap. The inspection already runs the full GSE schema, the package-integrity layer, and every auto-checkable compliance rule — each report states exactly what was covered.
