FORM UC-36 (REV. 09-2026)UCDP MANDATE: 2026-11-02
UADCHECKPre-submission inspection of UAD 3.6 packages

UAD1126

FATAL

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

Provide the 'Manufactured Home Width' (i.e., Single Wide, Multi Wide).

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

What triggers UAD1126

The published rule logic, verbatim:

If ImprovementType = "Dwelling" and ConstructionMethodType = "Manufactured" and ManufacturedHomeWidthType is not provided

  • Checked for the Subject property.
  • • Bound to MISMO data point ManufacturedHomeWidthType at ../VALUATION_ANALYSIS/PROPERTIES/PROPERTY/IMPROVEMENTS/IMPROVEMENT/MANUFACTURED_HOME/MANUFACTURED_HOME_DETAIL/

How to fix it

On the URAR, this lives at: Manufactured Home → Manufactured Home Width. 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.

UAD1126 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.
