UAD 3.6 is the updated Uniform Appraisal Dataset from Fannie Mae and Freddie Mac. It replaces fixed appraisal forms, such as the 1004, 1073, and 2055, with one dynamic Uniform Residential Appraisal Report (URAR). Report data follows the MISMO 3.6 standard and is delivered as a ZIP package with XML data, a PDF report, and images.

UAD 3.6 is mandatory for all new appraisal reports submitted to UCDP on or after November 2, 2026. The rule is based on the first UCDP submission date of each report. Revisions to UAD 2.6 reports first submitted before November 2 are accepted until May 3, 2027.

UAD 3.6 replaces the form set with one dynamic report, moves appraisal data to MISMO 3.6, and delivers each report as a ZIP package. Appraisers give separate interior and exterior condition and quality ratings. Above-grade and below-grade finished area replace gross living area, measured under ANSI Z765-2021.

Confirm that your appraisal management software, appraisal form software, UCDP and EAD integrations, and QC tools all handle UAD 3.6, and test UAD 3.6 submissions. UAD 2.6 appraisals must be submitted to UCDP before November 2, 2026 or converted to UAD 3.6.

Yes. For new UCDP submissions from November 2, 2026, the redesigned Uniform Residential Appraisal Report (URAR) replaces the 1004, 1073, 2055, and the other legacy forms. The property type and the assignment decide which sections the report includes. The GSEs publish a mapping of the legacy forms to the new URAR.

If a submission triggers a Fatal message, UCDP marks it Not Successful and the appraisal cannot be used to deliver the loan. The data is corrected and the report is resubmitted. From November 2, 2026, every new UAD 2.6 submission receives a Fatal message.

Yes. Connexions accepts UAD 3.6 and UAD 2.6 orders in one pipeline and submits to UCDP and EAD. Fannie Mae lists Connexions Software on its Integrated Vendor List for the Uniform Collateral Data Portal for UAD 3.6, and Freddie Mac lists it on its Software Providers List for UCDP.

From November 2, 2026, UCDP returns a Fatal message on any new UAD 2.6 submission, and that report cannot be used to deliver the loan. Every part of the chain has to be ready: appraisal management software, appraisal form software, and the UCDP and EAD integrations. Ask each vendor for its go-live date and a successful test submission.
