An industry update from Inspection.re, premium home inspections across California.
A Contra Costa County agent gets an appraisal back and sees the exterior condition rated differently from the interior. The agent calls the home inspector. Why did the appraisal find something the inspection missed?
It probably did not. The two documents were never measuring the same thing. The appraisal characterizes the property for valuation. The inspection operates systems and reports visible conditions for the buyer or seller. Starting November 2, 2026, that distinction will become easier to misread because the appraisal will report update status and condition status for specific property components.
This is a composite of a common question, not a specific Inspection.re job. The call usually starts with two reports that use similar words such as “condition,” but those words are doing different work.
November 2, 2026 is a submission deadline, not an inspection deadline
UAD 3.6 is mandatory for all new appraisal reports submitted to UCDP on or after November 2, 2026. UAD means Uniform Appraisal Dataset. UCDP means Uniform Collateral Data Portal.
The controlling event is the initial UCDP submission date. It is not the loan application date. It is not the date the appraiser visited the property. It is not the appraisal’s effective date. This is the detail agents get wrong.
A UAD 2.6 appraisal must be submitted to UCDP before November 2, 2026. If it is not, it must be converted to UAD 3.6. That can affect a transaction already in flight during the final days of October. The appraisal may have been completed under the older system, but the lender’s submission can place it on the other side of the deadline.
The agent does not control that submission. Neither does the appraiser on the agent’s timeline. If timing matters, ask the lender when the initial UCDP submission will occur. Do not work backward from the inspection date or the effective date printed on the appraisal.
The transition has already been underway for more than a year. The Limited Production Period started September 8, 2025. The Broad Production Period began January 26, 2026. On that date, Fannie Mae and Freddie Mac said, “All lenders are now permitted to submit UAD 3.6 appraisal reports to the Uniform Collateral Data Portal.” They also said submission “is not yet mandatory.”
That optional period ends with the November deadline. The GSEs have encouraged lenders to work with an appraisal software provider whose software has been verified for UAD 3.6.
The form number everybody quotes is going away
The familiar appraisal form numbers are being retired. That includes the Uniform Residential Appraisal Report, commonly called the 1004 or 70, and the Individual Condominium Unit Appraisal Report, commonly called the 1073 or 465.
The list goes further. Exterior-only inspection report variants are retired. So are the Manufactured Home Appraisal Report, 1004C or 70B, the Appraisal Update and/or Completion Report, 1004D or 442, and the Single Family Comparable Rent Schedule, 1007 or 1000.
Agents have said, “It’s a 1004,” for decades because the form number told everyone what kind of report was in front of them. The form selected the boxes and the structure that followed.
That shorthand stops working under UAD 3.6. Fannie Mae and Freddie Mac describe the replacement as “a single data-driven, flexible, dynamic structure for appraisal reporting.” The property data will determine what appears in the report.
You will need a different sentence. Instead of asking whether the appraiser is using a 1004 or 1073, ask whether the report is UAD 2.6 or UAD 3.6 and when it will first be submitted to UCDP.
The report is now built from the property, not from a form
The subject property now drives the appraisal report. Fannie Mae and Freddie Mac state it directly: “the data that describes the subject property drives the appraisal report.”
Under the legacy approach, the property type pointed the appraiser toward a particular form. The form then supplied the structure. A single-family residence and an individual condominium unit appeared in different documents because the form number came first.
UAD 3.6 reverses that order. The redesigned URAR, or Uniform Residential Appraisal Report, uses one dynamic reporting structure. The relevant property data determines the content that appears.
Two appraisals on different property types will therefore no longer present themselves as two separate legacy forms with different numbers and fixed boxes. They will use the same reporting structure, populated differently according to the properties being appraised.
The better question is no longer, “Which form did they use?” It is, “What property data drove this report?”
Interior and exterior condition are now rated separately
UAD 3.6 adds separate Interior Condition and Quality Ratings and Exterior Condition and Quality Ratings. Freddie Mac describes the purpose as providing “a distinction when there are significant differences in the condition status between interior and exterior.”
That distinction reflects houses agents and inspectors see every week. A property can have a clean, well-kept interior under a failing roof covering, with rotted exterior trim plainly visible. Another can have fresh exterior work while the interior systems and finishes show years of deferred attention.
The remodel does not settle the question. A fully rebuilt kitchen can sit inside a house whose foundation and drainage were never touched. In a market like Pleasant Hill, where most of the stock came out of one wartime and postwar building wave, that pattern shows up constantly: a current interior over original systems.
The legacy single condition rating could flatten those differences into one overall characterization. Separate ratings let the appraisal state that the interior and exterior do not present the same way.
If the exterior rating is lower, the appraisal has not replaced the roof evaluation, attic evaluation, or drainage observations in the inspection report. It has recorded a valuation-related condition distinction. Similar vocabulary does not create identical scope.
Component-level condition reporting is the change agents will feel
The redesigned appraisal records an “Update Status” and a “Condition Status” for specific property elements. Those entries support the appraiser’s opinion of the overall condition ratings.
This is the part agents will see in the report and then compare directly with the inspection. More property details will appear connected to the appraiser’s condition analysis. A buyer may assume that each entry represents a test. A seller may read an update status as approval of the work. Neither assumption follows from the reporting structure.
On October 21, 2025, Fannie Mae and Freddie Mac jointly published “UAD 3.6 and Forms Redesign: Inspection and Reporting Tips.” The UAD and Forms Redesign team created that document “to highlight notable differences in information collected between the legacy forms (UAD 2.6) and the redesigned Uniform Residential Appraisal Report (URAR) (UAD 3.6).”
The GSEs say appraisers can use it “as a job aid.” They also say it “focuses on new information requirements when physically inspecting the property or when researching property information and completing the URAR.”
That phrasing matters. The redesign requires more specific information connected to the appraiser’s physical observation and property research. It does not turn the appraiser into a home inspector.
More granular reporting is not diagnostic reporting. A condition status does not tell you that a component was operated. An update status does not tell you why something failed, whether a repair corrected the underlying issue, or what may be concealed behind finished surfaces.
A more detailed appraisal is still not a home inspection
A more detailed appraisal is still an opinion of value prepared for the lender. The lender is the client.
A home inspection is a condition assessment prepared for the buyer or seller. The buyer or seller is the client. That client difference is the cleanest explanation for why the reports can discuss the same house and still produce very different information.
The appraiser is characterizing the property for valuation. The home inspector is evaluating visible and accessible conditions and operating systems. Those are separate assignments, and the scope we actually work to is written around the second one.
An appraiser can record a roof condition from the ground without walking the roof or entering the attic. That may be sufficient for the appraiser’s valuation work. It is not the same as an inspection that evaluates the roof by walking it or by another method and enters the attic where access allows.
The same distinction applies inside. A home inspection runs the furnace and air conditioning. It fills and drains plumbing fixtures. It tests every accessible receptacle. It opens the electrical panel. It enters the crawlspace where access allows.
An appraiser may observe a system, describe its condition, and account for it in the value analysis. That does not mean the system was operated or tested. It does not mean the appraiser diagnosed why it failed.
Where the two documents will look like they disagree, and why they do not
The reports will appear to disagree whenever a broad valuation characterization sits beside a specific inspection finding. Both statements can be accurate because they answer different questions.
An appraisal might characterize a system as adequate for valuation. The inspection might report that the same system did not operate as expected during testing. The appraisal describes how the property is treated in the value analysis. The inspection records what happened when the component was operated.
An appraisal might record that a component has been updated. The inspection might call out visible work that looks unpermitted or identify a defect within that work. “Updated” describes status. It does not mean the installation was tested, approved, or found free of visible defects. This comes up on older stock constantly, and the Martinez housing core, where a great deal of the downtown fabric predates the automobile suburb, is exactly the kind of market where a century of undocumented work sits behind newer finishes.
The appraisal might give the exterior a worse rating than the interior. The buyer may care most about the remodeled interior and wonder why the appraisal sounds negative. The separate rating is doing exactly what it was designed to do. It preserves the difference instead of compressing both areas into one condition rating.
The reverse can happen too. A polished exterior does not settle what is happening at the furnace, receptacles, plumbing fixtures, electrical panel, attic, or crawlspace. It also does not settle what is happening in the ground underneath, which in a market like Antioch, where part of the city sits over a nineteenth century coal field, is a genuinely separate question from anything either document rates.
These are not competing verdicts on the house. One document supports a lender’s valuation decision. The other gives the buyer or seller a visual, non-invasive condition assessment.
A home inspector cannot and should not reconcile an appraisal. We do not know how the lender used particular property data in its process, and we do not set the condition ratings used for valuation. Questions about the appraisal, its ratings, or its effect on the loan go to the lender.
Use the inspection report to discuss observed conditions. Use the appraisal process to discuss value and lending. Combining them produces bad questions and worse expectations. If a client has never read a condition report closely, our guide to how to read a home inspection report in California is a better starting point than a side-by-side comparison with the appraisal.
What an inspection still does that no appraisal does
A home inspection operates accessible systems and evaluates accessible areas for the buyer or seller. It is not a value report.
The inspector runs the furnace and air conditioning. The inspector fills and drains fixtures, rather than simply noting that they exist. Every accessible receptacle is tested. The electrical panel is opened. The roof is walked or otherwise evaluated. The attic and crawlspace are entered where access allows. What a finished report contains is a record of those specific actions and what they produced.
The limits matter just as much. A home inspection is visual and non-invasive. We do not open walls. We cannot report what finished surfaces conceal. The report is a snapshot of one day, not a prediction of future performance.
A home inspection does not predict remaining life. It does not say how many months or years a roof, furnace, air conditioner, or other component will continue to serve. It does not provide an opinion of value.
Inspection.re does not perform appraisals. We do not set value, and we cannot tell a client what a property is worth. Our report answers a different question: what visible and accessible conditions were present when we inspected and operated the systems within the inspection’s scope? The same boundary applies on a brand new house, which is why new construction still gets its own inspection rather than resting on the lender’s paperwork.
That question remains necessary after UAD 3.6. More fields in an appraisal do not operate a furnace, open a panel, test a receptacle, drain a fixture, enter an attic, or evaluate a crawlspace. Agents tracking what else shifted this year will find the rest of it in our roundup of the California laws and rules affecting inspections.
Quick answers
Does this change what a home inspection covers?
No. Nothing about UAD 3.6 changes an inspection’s scope or standard of practice. The appraisal redesign applies to appraisal data and reporting for loans sold to Fannie Mae or Freddie Mac. The separate question of what inspectors themselves adopted this year is covered in our summary of the 2026 ASHI standard of practice changes.
My appraisal came back on a 1004. Is it invalid?
The controlling fact is the initial UCDP submission date. UAD 3.6 is mandatory for new appraisal reports first submitted on or after November 2, 2026. The loan application date and appraisal effective date do not decide the issue. Ask the lender when the appraisal was first submitted to UCDP.
Will the new appraisal find defects the inspection missed?
Not necessarily. An appraiser records condition information for valuation. An inspector operates accessible components and reports visible conditions. A component-level appraisal entry is not proof that the component was tested or that a failure was diagnosed.
Should a buyer skip the inspection now that the appraisal is more detailed?
No. The appraisal is prepared for the lender, which is the client. The home inspection is prepared for the buyer or seller, who is the client. More appraisal detail does not change that division or replace system operation and accessible-area evaluation. Our common questions page covers what a buyer should expect to happen on the day.
Does this apply to every loan?
No. This change applies to loans sold to Fannie Mae or Freddie Mac. Do not assume the same rule applies to another loan type. Direct loan-specific questions to the lender.
The honest summary
On November 2, 2026, UAD 3.6 becomes mandatory based on the appraisal’s initial UCDP submission date. The old form numbers retire, interior and exterior receive separate ratings, and specific property elements receive update and condition statuses.
For late October transactions, ask the lender for the planned UCDP submission date. Send appraisal questions to the lender. Keep the home inspection focused on observed conditions and operated systems. The appraisal answers the lender’s question about value. The inspection answers the buyer’s or seller’s question about condition. A more granular appraisal does not merge them. If you work Contra Costa County listings around Concord and Walnut Creek, or anywhere else we cover, that division is the one thing worth repeating to every client before the file opens.
