UAD1019

FATAL

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

The 'Units Excluding ADUs' does not equal the number of living units delivered in the UAD XML.

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

What triggers UAD1019

The published rule logic, verbatim:

If LivingUnitExcludingADUCount does not equal the number of instances of PROPERTY_UNIT_DETAIL with AccessoryDwellingUnitIndicator = "false"

• Checked for the Subject property.
• Bound to MISMO data point LivingUnitExcludingADUCount (%PV%) at ../VALUATION_ANALYSIS/PROPERTIES/PROPERTY/PROPERTY_DETAIL/

How to fix it

On the URAR, this lives at: Subject Property → Units Excluding ADUs (%PV%). 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.

UAD1019 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.
