Starting July 28, 2026, most co-op boards in New York City must follow mandatory timelines when reviewing purchase applications. The law — formally titled the Cooperative Application Timeline Law, Local Law 2026/058, and known in its legislative history as Intro 1120-B — represents the first time the city has imposed enforceable deadlines on how co-op boards process buyer applications. For buyers, sellers, and brokers, it changes the calculus of every co-op transaction submitted on or after that date.

A Long Time Coming

New York City has more co-ops than any other municipality in the country — over 6,800 buildings encompassing roughly 450,000 occupied units. For most of that history, boards have operated with near-total discretion over the admissions process: who reviews applications, when they review them, and what they say afterward. 

That opacity has drawn criticism for decades, and not only on efficiency grounds. Fair housing advocates have long argued that the unstructured process created cover for discrimination. Because boards were not required to explain their decisions, applicants had no way to assess whether a denial reflected a financial concern or something else entirely.

The legislative effort to address this gained meaningful traction in 2023, when Public Advocate Jumaane Williams and Council Member Pierina Sanchez introduced a package of three bills aimed at co-op reform. One bill — Intro 914, the precursor to 1120-B — targeted the application timeline. A companion bill, Intro 915, would have required boards to provide written reasons for turndowns. A third would have required financial disclosure to prospective buyers. The timeline bill ultimately advanced. The other two stalled.

Majority Leader Amanda Farías sponsored the version that passed, framing it plainly: "In the cooperative housing process, buyers are often left without any response at all, creating uncertainty, financial strain, and a system where discrimination can persist without accountability."

The City Council passed the bill in December 2025, 46 to 2. Mayor Adams vetoed it on December 31. On January 29, 2026, the Council overrode the veto, and the law took effect with a 180-day implementation window.

What the Law Requires

The law applies to co-op buildings with 10 or more residential units. It covers not only standard purchase applications but all board-approved transfers, including trust transfers, gifts, family transfers, and estate transfers. Condominiums are exempt. So are HDFC cooperatives and Mitchell-Lama developments.

The 15-day acknowledgment window.

Within 15 days of receiving an application, the co-op — meaning the board or its managing agent — must send written acknowledgment by both email and registered mail. That acknowledgment must state whether the application is complete. If it is not complete, the co-op must identify specifically what’s missing.

If no acknowledgment is sent within 15 days, the application is deemed complete by operation of law. That triggers the 45-day decision clock immediately, regardless of whether the board has actually reviewed the package.

The 45-day decision window.

Once an application is complete — either because the board said so or because the 15-day window lapsed — the board has 45 days to notify the applicant in writing whether the application is approved, conditionally approved, or denied.

Extensions.

The board may extend the 45-day window once by 14 days without the applicant's consent, provided it gives notice before the original deadline. If additional information is requested during review, another 14-day extension is available. Further extensions require the applicant's written consent.

Summer recess.

Boards that do not meet during July or August may pause both clocks during those months — but only if the recess is documented in a written policy maintained in the building's records and disclosed to applicants in advance. The recess cannot be invoked informally.

Standardized application package.

Boards must maintain and provide on request a written application package and a complete list of transfer requirements: all forms, fees, disclosures, interview procedures, and submission instructions. These materials must reflect the co-op's actual current practices, not an outdated or aspirational version of them.

Managing Agents Are On the Hook

One of the most consequential — and least-discussed — features of the law is that managing agents carry direct statutory liability, not just a delegated obligation from the board.

The 15-day acknowledgment clock starts when the application is received by the co-op entity, which in practice means the managing agent's office. A managing agent who receives a package on a Monday and holds it for three weeks before forwarding it to the board has not paused the clock. The clock was running the entire time. If no acknowledgment went out by day 15, the application may already be deemed complete before the board has seen a single page.

This is a real operational shift. Managing agents will now need intake protocols that track receipt dates, systems for issuing registered mail acknowledgments, and workflows for completeness review — all within a two-week window that includes the time required to actually prepare and mail a certified letter.

Enforcement

The Department of Housing Preservation and Development (HPD) enforces the law. Violations are adjudicated at the Office of Administrative Trials and Hearings (OATH). Penalties are $1,000 for a first violation, $1,500 for a second, and $2,000 for each subsequent violation.

One clarification worth noting: missing the 45-day deadline does not result in automatic approval. The law does not grant deemed approval on the back end the way it does on the front end (the 15-day completeness window). A missed deadline triggers an HPD complaint and potential fines — not a transfer of shares.

What This Means If You're Buying or Selling a Co-op

For buyers, the most immediate benefit is timeline clarity. Under the old system, a buyer could submit a package with no idea whether the board had received it, whether it was complete, or when a decision might come. Mortgage rate locks routinely expired during indefinite review periods, forcing buyers into costly resets or exit clauses. That uncertainty is now bounded.

For sellers, the carrying cost argument is equally concrete. Every month of board limbo is another month of maintenance, mortgage, and unresolved plans. The law doesn't guarantee a fast decision — boards can still use the full 60-day window (45 days plus a unilateral 14-day extension) before responding — but it ends the open-ended waiting.

For brokers, the practical change is documentation. The date an application is submitted to the managing agent is now a legally significant event. Confirm delivery in writing. Keep the record.

One caveat the law does not address: the interview process. Boards are still free to schedule interviews whenever they choose within the 45-day window. For a volunteer board with limited availability and a compressed calendar, that coordination can be genuinely difficult. The timeline is bounded; it is not frictionless.
