One and two family owners
The zoning changed in your favor, but the money didn’t last. Intake for the city’s Plus One ADU financing closed on June 12, 2026.
Plenty of pages still promise Brooklyn homeowners up to $395,000 to build a basement or backyard apartment. That intake window is shut. What’s still open is the zoning, the free plan library, and the question most owners actually care about: what an extra unit does to a sale.
The city reopened financing for accessory dwelling units in March 2026 and launched an ADU for You toolkit alongside it. Thousands of homeowners responded to the intake survey.
Intake closed on June 12, 2026. The program is now working through those sites for eligibility, and owners who responded hear back either way by email.
So if you’re reading a page that tells you to go get $395,000 today, it’s out of date. That matters, because several owners we’ve spoken with were budgeting a renovation around money that isn’t currently taking applications.
| What you may have read | Where it stands now |
|---|---|
| Up to $395,000 in city and state assistance | Real, but intake closed June 12, 2026. Sites submitted before then are under review. |
| ADUs are legal across the five boroughs | Zoning was expanded by City of Yes, adopted December 2024. Eligibility depends on your zoning district. |
| Pre-approved plans from the city | Available. The plan library launched with nine city-reviewed designs for detached backyard cottages. |

Most calls we get about basements aren’t about building one. They’re from an owner who already has a finished unit downstairs and is thinking about selling.
That’s a real conversation, and it’s different from the construction one. A unit that was never permitted doesn’t disappear at closing. It follows the property, and the buyer inherits it.
Buyers, appraisers and lenders each look at it differently. An unpermitted apartment generally doesn’t count as legal living space in an appraisal, and its rent generally can’t be used to help a buyer qualify. That gap between what the space feels like and what it counts for is where deals get uncomfortable.
Get the certificate of occupancy and the property’s open violations pulled before you price anything. What the record says the house is matters more than what the house looks like.
Then price the house honestly for what it legally is. Marine Park and Midwood have real buyer pools for both a legal two-family and a one-family with finished space, and they aren’t the same buyers.
The Behfar Team has sold houses in this exact situation across Midwood, Madison and Marine Park, and we’ll say plainly when a listing needs the paperwork addressed first. Our Marine Park page covers how we read that market. If you want the sale side in full, start with how we handle a Brooklyn sale.
The City of Yes zoning changes opened accessory units in a range of lower-density residential districts, with limits by district and lot. Your zoning district and lot conditions decide it, so check the property rather than the borough.
A legal, documented unit adds usable income and widens the buyer pool. An undocumented one adds risk that a buyer prices in, or walks away from. The paperwork is most of the difference.
Yes, houses in this condition sell in Brooklyn regularly. It changes how you disclose, how you price and which buyers can finance it. It should never be hidden.
The city hasn’t announced a new intake window. Owners who submitted before June 12, 2026 are still in the eligibility review.
Those are separate rules. The surcharge turns on value and on who lives there, not on how many units you have. Our 2026 rules overview puts all three changes side by side.
We’ll look at the certificate of occupancy, the space and the comparable sales, then tell you what the house realistically brings.
