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

UAD1741

FATAL

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

The cooperative proprietary lease expiration date must include year and month (YYYY-MM format).

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

What triggers UAD1741

The published rule logic, verbatim:

If CooperativeProprietaryLeaseExpirationDate is not provided in YYYY-MM format.

  • Checked for the Subject property.
  • Required format: year and month, CCYY-MM (e.g., 2026-03).
  • • Bound to MISMO data point CooperativeProprietaryLeaseExpirationDate (%PV%) at ../VALUATION_ANALYSIS/PROPERTIES/PROPERTY/PROPERTY_DETAIL/

How to fix it

On the URAR, this lives at: Project Information → Cooperative Information → Proprietary Lease Expires (%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.

The free UADCheck inspection evaluates UAD1741 automatically — attach your package and see in seconds whether it fires.
