UAD 3.6 is the new reporting dataset that prescribes how measured information, as determined by the ANSI standard, is to be formatted, documented, and transmitted electronically to the GSEs.

Fannie Mae and Freddie Mac have lead this initiative to update and modernize the appraisal dataset and align it with the mortgage industry standard, pushing the standardization further.

UAD 3.6 will start being used on the 8th of September 2025 by a limited number of lenders and will be available to all on January 25th 2026. It will become mandatory in November 2026.
​

Cubicasa will let you start using the 3.6 output from September 8 so you can get accustomed to it.

Here are the dedicated GSEs links to get all the information you shall need about it:

With UAD 3.6 there are also expectations on the informations available on the floor plan, and the area information that comes with it. Our new version of the ANSI-Z765 compatible floor plan cover this, and we also provide you with the additional calculation that are expected.

There's a new blueprint legend to clearly identify the different type of spaces. We detail it in our dedicated article but here is a preview of what to expect:
​

New data are expected to be provided for each floor as well as for the property. These set of data aims at a more comprehensive approach especially with the addition of Non-Standard Finished Area. Our report will provide you the following information which are expected, this example matchs the first image above.

As you see, Cubicasa is ready to provide you all the information it can as expected by GSEs. Appraisers can start testing before UAD 3.6 becomes mandatory.

Once this is done, you will be able to download the new UAD 3.6 compatible documents alongside the current version of GLA you already know.

This will give you time to get accustomed to the new layout and to ask questions and give us feedback.
