If you are selling a Manhattan co-op, the new city review deadlines can make one part of the transaction easier to track. They do not start when you list, accept an offer, or sign a contract. Under New York City’s Local Law 58 of 2026, the key dates concern the buyer’s application to the cooperative and the point at which that application is complete. A seller still needs a building-specific plan for the package, financing, contract dates, and closing.
Check whether the law covers your building
The law took effect July 28, 2026, for applications made on or after that date. It generally covers New York City cooperative corporations with at least 10 residential units when a transfer requires the co-op’s consent. The law excludes certain housing development fund companies and co-ops whose transfers require government housing-agency approval. Ask your attorney and managing agent to confirm how your building and sale fit the law before treating its deadlines as your calendar.
Know when the two clocks start
The co-op must provide a written acknowledgment within 15 days after receiving an initial application or later submission. That acknowledgment must say whether the application is complete and identify missing items if it is not. Once the application is acknowledged as complete, or is deemed complete because the co-op did not acknowledge it on time, the co-op generally has 45 days to notify the buyer or buyer’s agent whether it consents, conditionally consents, or denies consent. The law allows one extension of up to 14 days with timely notice; a buyer can also agree in writing to more time. A properly noticed July or August summer recess can pause certain deadlines.
These are board-review rules, not a promise that the apartment will close within 45 days. The law does not make a missed deadline an automatic approval, and it does not eliminate the board’s ability to deny an application lawfully. Financing, contract conditions, and closing arrangements can add time outside the board’s decision window.
Prepare the seller side before offers arrive
Request the building’s current application and complete transfer requirements early. Confirm the submission method, fees, interview process, and whether management has a stated summer recess. Keep a dated record of when the buyer’s package and any follow-up materials are delivered. If the buyer or management flags an incomplete item, ask for the specific missing requirement and the next submission date.
Your own records matter too. Have your attorney review the proprietary lease, share information, any building charges due on transfer, and the contract’s board-approval provisions. If you are also buying another home, plan that move around actual milestones rather than an assumed board decision date. Our guide to comparing Manhattan co-op offers explains why a buyer’s ability to meet the building’s requirements matters alongside price.
Keep the contract calendar aligned
Before signing, ask your attorney how the contract defines package submission, board approval, cancellation rights, and any outside date. A statutory review deadline and a contract deadline may be triggered differently. When the package is submitted, track the co-op’s acknowledgment and any extension in writing, then have the attorneys address a conflict before a date expires.
