How to fix UAD1660

UAD1660 is a Fatal UAD 3.6 edit, so clear it before the appraisal report goes to UCDP.

  1. 01Open the Highest and Best Use › Legally Permissible area of the URAR and find Legally Permissible.
  2. 02Check the condition that triggers UAD1660: LegallyPermissibleIndicator is not provided.
  3. 03Correct the missing, invalid, duplicate, or inconsistent value before submitting to UCDP.
  4. 04Use the official Single-family (SF1) sample value on this page as a reference pattern, then re-run validation.

This fix guidance is derived from the published rule message, trigger logic, report location, field definition, and official sample data available for this rule.
