Your Complete Guide to the UAD 3.6 Updates Follow
On Tuesday, October 27, 2026, Doorify MLS will add and update several Listing Manager fields to support the Uniform Appraisal Dataset (UAD) 3.6, the standard Fannie Mae and Freddie Mac use for appraisals.
Most new fields stay hidden until an answer unlocks them, so most listings only get one or two new questions.
You'll notice these updates at the following times in your workflow:
| When you… | What's new | Applies to |
|---|---|---|
| Close a listing | Concessions is now required; new Concession Type field; three new Buyer Financing choices | Concessions: all property types. Buyer Financing: Res, Res Income, Land, Comm Sale |
| Enter a Residential listing | New Accessory Dwelling Unit (ADU) question, with up to nine detail fields if you answer Yes | Res |
| Enter other listing details | Primary Bedroom Main Floor (new required search filter), Power Production Ownership for solar, and an ADU choice for Residential Lease | Res; Lease |

How to Read the Updated Field Guide
| Term | What it means for you |
|---|---|
| Required | Must be filled in. |
| Required when… | Only required after a specific earlier answer (for example, ADU = Yes). |
| Optional | Fill it in if you know it; you can save without it. |
| Shows when… | The field stays hidden until the earlier answer is picked. |
| Property types | Res = Residential, Res Income = Residential Income, Comm Sale = Commercial Sale, Lease = Residential Lease. |
1. When you close a listing
Concessions
Concessions is now required on every closing, and "Call Listing Agent" is no longer a choice. Have the settlement statement handy before you change the status to Closed.
| Field | What changed | Choices | Shows when… | Required? | Property types |
|---|---|---|---|---|---|
| Concessions | Now required. "Call Listing Agent" is removed. | Yes, No | Always, when changing status to Closed | Required | All |
| Concession Type (New) | New pick-all-that-apply field | Interest Rate Buydown; Closing Costs; Condo / HOA Fees or Assessments; Non-Realty Items; Home Warranty; Builder Financing; Builder Incentive; Repairs or Repair Allowance; Seller Credit; See Comments/Other | Concessions = Yes | Required when Concessions = Yes | Res, Res Income, Land, Comm Sale |
| Concessions Amount | New rule on existing field | Dollar amount | Concessions = Yes | Required when Concessions = Yes | All |
| Concessions Comments | New rule on existing field | Free text | Concessions = Yes | Required when Concession Type includes "See Comments/Other" | All |
| Quick path: Concessions = No → done. Concessions = Yes → pick the type(s) and enter the amount. Picked "See Comments/Other"? → explain it in Concessions Comments. |
When you close a listing: Buyer Financing (three new choices)
Buyer Financing is still pick-all-that-apply, and nothing else about the field changes. Applies to Res, Res Income, Land and Comm Sale.
| New choice | Use it when… |
|---|---|
| 1031 Exchange | The buyer is using a like-kind exchange. |
| Construction to Permanent | One loan covers the build and converts to a mortgage. |
| Special Funding | The seller may be interested in a special funding arrangement. |
2. When you enter a Residential listing: Accessory Dwelling Unit (ADU)
Every Residential listing now asks one Yes/No question about an ADU. Answer No and move on; answer Yes and up to nine detail fields open.
| Field | Choices or format | Shows when… | Required? |
|---|---|---|---|
| ADU Y/N | Yes, No (starts blank) | Always | Required |
| ADU Type | Attached, Detached, Within | ADU = Yes | Required when ADU = Yes |
| ADU Sub-Type | Basement, Attic, Addition, Garage Conversion, Above-Garage, Converted Outbuilding, Purpose Built, Residential Lease, Other | ADU = Yes | Required when ADU = Yes |
| ADU Bedrooms | Whole number | ADU = Yes | Required when ADU = Yes |
| ADU Bathrooms | Number, decimals allowed; minimum 1 | ADU = Yes | Required when ADU = Yes |
| ADU Living Area (SqFt) | Whole number, greater than 0 | ADU = Yes | Required when ADU = Yes |
| ADU Year Built | 4-digit year, 1800 to next year | ADU = Yes | Required when ADU = Yes |
| ADU Permitted | Yes, No (starts blank) | ADU = Yes | Required when ADU = Yes |
| ADU Rentable | Yes, No (starts blank) | ADU = Yes | Optional |
| ADU Current Rent | Dollar amount | ADU Rentable = Yes | Optional |
| Quick path: ADU = No → done. ADU = Yes → type, sub-type, beds, baths, square feet, year built and permitted. Rentable and rent are optional. |
3. More listing changes: Primary Bedroom, Solar, and Lease ADUs
Buyers can now filter for a primary bedroom on the main floor, so every Residential listing asks. Solar listings get a new ownership field, and Residential Lease listings can now be marked as an ADU.
| Field | Choices | Shows when… | Required? | Property type |
|---|---|---|---|---|
| Primary Bedroom Main Floor Y/N (New search filter) | Yes, No (starts blank) | Always | Required | Res |
| Power Production Ownership (New) | Seller Owned, Third Party Owned | Power Production YN = Yes | Required when Power Production YN = Yes | Res |
| Property Sub Type (New choice) | Adds "Accessory Dwelling Unit" | No change | No change | Lease |
4. For Appraisers: What's New in the Data
Starting October 27, closed and active listings carry more of the detail UAD 3.6 asks for. Here's where to find it when you pull comparables.
| What you're checking | Where to look | What you'll find |
|---|---|---|
| Seller concessions | Concessions, Concession Type, Concessions Amount, Concessions Comments | A required Yes/No on every closing. When Yes: the type(s), a dollar amount, and comments when "See Comments/Other" is picked. |
| Financing | Buyer Financing | Three new choices: 1031 Exchange, Construction to Permanent, and Special Funding. |
| Accessory dwelling units | ADU Y/N and ADU detail fields | Every Residential listing answers ADU Y/N. When Yes: type, sub-type, bedrooms, bathrooms, living area (SqFt), year built and permit status. Rentable status and current rent may also be filled in. |
| Lease ADUs | Property Sub Type (Lease) | "Accessory Dwelling Unit" is now a choice on Residential Lease listings. |
| Main-floor living | Primary Bedroom Main Floor Y/N | A required Yes/No on every Residential listing. |
| Solar | Power Production Ownership | Seller Owned or Third Party Owned, whenever Power Production YN = Yes. |

- These rules apply to listings entered or closed on or after October 27. Older listings may not have these fields filled in.
- ADU Rentable and ADU Current Rent are optional, so they may be blank even when an ADU exists.
