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

UAD1224

FATAL

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

'ServiceType' = 'Inspection' must be delivered no more than once. For assistance with this message, contact the appraisal software vendor.

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

What triggers UAD1224

The published rule logic, verbatim:

If there is more than one instance of SERVICE_DETAIL with ServiceType = "Inspection"

  • Allowed range: 0 to 1.
  • • Bound to MISMO data point ServiceType at ../SERVICE/SERVICE_DETAIL/

How to fix it

This requirement applies to the XML data itself — the field is delivered in the submission file but is not printed on the form. Your form software populates it from the report data; correct the underlying entry, regenerate the package, and re-check.

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

The free UADCheck inspection evaluates UAD1224 automatically — attach your package and see in seconds whether it fires.
