What Is UAD 3.6?
UAD 3.6 Explained
A California Guide to the New Residential Appraisal Report
By Guaranty Escrow | Guidance checked September 30, 2026
Uniform Appraisal Dataset (UAD) 3.6 is Fannie Mae and Freddie Mac’s updated standard for residential appraisal data. It supports a redesigned Uniform Residential Appraisal Report (URAR) that adapts to the property and assignment instead of relying on separate, fixed forms. The dataset follows MISMO Reference Model 3.6. See Fannie Mae’s UAD overview.
For California buyers, sellers, and real estate agents, the practical question is how the appraisal fits into the financing and closing schedule. This guide explains what to ask your lender, what information to organize, and where escrow coordination can help.
UAD 3.6 is a national mortgage-industry standard, not a California-only law or an escrow service. Guaranty Escrow administers real estate escrows; your lender and appraiser address appraisal requirements and valuation.
When Does UAD 3.6 Become Mandatory?
The November 2, 2026 mandate has not been cancelled. A September 30 announcement introduced temporary exceptions for approved mortgage Sellers that need more implementation time. Here, “Seller” means a lender selling loans to a GSE, not the homeowner selling a property. Exceptions must be obtained from each applicable GSE. Read the joint policy announcement.
- November 2, 2026: UAD 3.6 mandate; eligible Sellers need an approved exception to continue new UAD 2.6 submissions.
- March 1, 2027: Reduced collateral-review functionality applies to UAD 2.6 reports during the exception period.
- May 20, 2027: New UCDP appraisal submissions must use UAD 3.6.
- June 28, 2027: UAD 2.6 is retired; legacy resubmissions are no longer accepted.
Source: official transition timeline. The mandate is tied to the appraisal’s initial submission to the Uniform Collateral Data Portal (UCDP), not simply your loan application or closing date. Confirm the applicable process with your lender. Official implementation FAQs.
UAD 2.6 vs. UAD 3.6: What Changes?
| Topic | Legacy approach | Redesigned approach |
|---|---|---|
| Report format | Separate forms identified by form number. | A dynamic URAR driven by property characteristics. |
| Property description | Form selection provides much of the context. | Structured property data determines relevant report sections. |
| Reading the report | Readers recognize familiar fixed layouts. | Readers follow applicable sections within one reporting framework. |
The GSEs’ legacy-form mapping guide explains this shift. That guide describes reporting, not automatic loan eligibility.
UAD is the underlying dataset; URAR is the appraisal report it supports. Neither is the Closing Disclosure. Knowing the distinction helps you direct questions to the right member of your transaction team. Freddie Mac’s UAD resources explain the redesigned reporting framework.
What California Buyers, Sellers, and Agents Should Consider
The following are planning examples, not reports of completed Guaranty Escrow transactions. They show how to prepare useful questions without assuming that a reporting change determines a property’s value or financing eligibility.
A Los Angeles Home With an ADU
The updated reporting captures more ADU detail, including separate interior information and measurements. Organize available plans, permits, rental information, and access arrangements, then ask the lender or appraiser which records are needed. A report entry is not a substitute for confirming permits or lawful use. See the GSE inspection and reporting tips and our ADU escrow services.
A South Bay Condo Purchase
Keep the lender’s appraisal request, association-document requests, and escrow milestones on one checklist. Ask who owns each outstanding item and when it is expected. Do not assume that receiving an appraisal also resolves every other lender condition. Your agent and lender can identify the property and financing questions that remain.
A Home With Solar or Recent Improvements
The new reporting includes more detail about renewable-energy components and their ownership, as well as interior updates. Keep available solar agreements, improvement records, and relevant contractor documents organized. Ask what must be reviewed and avoid promising that an upgrade will produce a particular appraised value. Official reporting guidance.
A Sale With Outstanding Repairs
If repairs remain, clarify whether completion is required before funding. An agreed repair escrow holdback may be an option only when the transaction and lender requirements permit it. Escrow cannot override those requirements, inspect the property, or guarantee workmanship.
How Appraisal Questions Connect to Escrow
The most useful distinction is between appraisal work and escrow work. Ask the lender about the required reporting format, appraisal review, and remaining financing conditions. Ask the appraiser questions through the appropriate transaction channel. Ask your escrow officer about instructions, documents, funds, and closing coordination.
Guaranty Escrow can help keep the escrow side organized as the parties address outstanding requirements. We do not determine property values, submit appraisals for lenders, approve loans, or guarantee a closing date. A clear plan identifies the next action, the responsible person, and the information needed to move forward.
For example, if a repair-completion document is outstanding, ask the lender what evidence it requires and ask escrow whether any related instructions remain incomplete. Treat those as separate tasks. A payment receipt should not be assumed to resolve an appraisal or funding condition.
A Practical UAD 3.6 Closing Checklist
- Confirm the appraisal process early. Ask your lender which reporting standard applies, when it expects the appraisal, and who will handle follow-up questions.
- Organize property information. Gather available improvement records, ADU documents, solar agreements, and access contacts. Supply requested records through the lender’s or appraiser’s appropriate channel.
- Separate the milestones. Track appraisal delivery, lender review, any requested corrections, financing approval, and escrow readiness individually. “Appraisal received” should not be your only status update.
- Address changes in writing. If the transaction timeline or repair arrangement changes, ask the relevant parties what amendments or approvals are needed before relying on a revised closing plan.
- Confirm the remaining closing items. Before making moving or funding arrangements, request a current status from your lender, agent, and escrow officer. Use your established secure process for financial instructions.

UAD 3.6 Frequently Asked Questions
1. Is UAD 3.6 a California requirement?
No. It is a national GSE appraisal-reporting initiative. California transactions can be affected when the relevant lender and loan requirements call for it.
2. What is the difference between UAD 3.6 and the new URAR?
UAD 3.6 defines the appraisal data; the redesigned URAR presents the report. They are related parts of the same modernization effort.
3. Did the November 2026 deadline move?
The mandate remains November 2. Approved exceptions allow new legacy submissions through May 19, 2027. This is not an automatic extension for everyone; ask your lender about its implementation.
4. Will every mortgage use UAD 3.6 on the same date?
Do not assume so. The GSE FAQ directs readers to FHA, VA, and USDA for those agencies’ implementation plans. Your lender should confirm the requirements for your loan.
5. Does UAD 3.6 automatically change my home’s value?
No specific value increase or decrease should be inferred from a new reporting format. Direct valuation questions to your lender and appraisal professional, rather than treating the version number as a price signal.
6. Should I expect a longer escrow?
There is no closing-time promise in this guide. Ask about appraisal scheduling, review, and outstanding conditions early. Share material timeline changes with your agent and escrow officer.
7. Can a home with an ADU use the redesigned report?
The URAR includes ADU reporting. That does not itself establish zoning compliance or financing eligibility. Ask which property records and lender reviews apply to your transaction.
8. Can a repair holdback solve an appraisal condition?
Not automatically. Obtain the required lender and transaction approvals before relying on a holdback. Its instructions must specify how funds are held and released.
9. Does Guaranty Escrow prepare or approve UAD appraisals?
No. Our role is neutral escrow administration. Lenders and appraisal professionals handle appraisal reporting and review; GE coordinates the escrow tasks within its instructions.
10. What should I ask before scheduling my closing?
Ask whether appraisal review is complete, which lender conditions remain, who is responsible for each item, and whether escrow has the required instructions and documents. Confirm status before making irreversible plans.
For official answers on implementation, consult the joint UAD FAQs and Freddie Mac’s UAD resource center.
