How to comply with Local Law 58: the co-op application timeline that takes effect today

Local Law 58 of 2026 (Int. 1120-B) takes effect today, July 28, 2026. Every residential co-op corporation in New York City with ten or more units must now follow a defined timeline when processing purchase applications: 15 calendar days to acknowledge receipt and confirm completeness, then 45 calendar days from a complete application to issue a final determination. The first application submitted on or after today starts the clock. Boards that miss the deadlines face HPD enforcement proceedings before OATH, with penalties starting at $1,000 per violation. This post walks through what the law requires, who it covers, what managing agents must do now, and what the law does not fix.

What the law requires, step by step.

LL58 amends the NYC Administrative Code to impose two sequential timelines on co-op purchase applications.

The first clock starts when an applicant submits a purchase application. The co-op corporation (or its managing agent acting on the corporation's behalf) has 15 calendar days to send the applicant two things: an acknowledgment of receipt, and either a written confirmation that the application is complete or a written list of any missing items needed to complete it. The acknowledgment must go out by email and by registered or certified mail. Both formats are required; one alone does not satisfy the statute. If the co-op sends no acknowledgment within 15 days, the law treats the application as deemed complete as of the submission date, and the second clock begins automatically.

The second clock starts from the date the application is deemed complete. From that date, the co-op has 45 calendar days to issue a final determination: approval, conditional approval, rejection, or a written request that the applicant appear before the board. The 45-day period does not pause while the board waits for a quorum at its next scheduled meeting. It does not extend automatically because a supplemental document arrived late. It runs from the complete-application date to the determination date, and it is the board's obligation to fit its process within that window.

If the co-op misses the 45-day deadline, the applicant may file a complaint with HPD. HPD brings enforcement proceedings before the Office of Administrative Trials and Hearings (OATH). The penalty schedule under the law is $1,000 for a first violation, $1,500 for a second violation, and $2,000 for each subsequent violation.

Who it applies to — and who is exempt.

The law applies to "cooperative corporations," defined in the NYC Administrative Code as corporations organized to own a residential building where shareholders hold proprietary leases. The ten-unit floor excludes very small co-op buildings. A four-unit brownstone co-op is outside the mandate; a twelve-unit co-op building is not.

Three categories of co-ops are expressly exempt: HDFCs (Housing Development Fund Corporations), Mitchell-Lama cooperatives, and limited-equity cooperatives organized under Article XI of the Private Housing Finance Law. Those buildings operate under separate regulatory structures with different application norms, and LL58 does not alter them.

Condominiums are not covered. A condominium does not process purchase applications the way a co-op does. Condos have right-of-first-refusal review processes governed by their offering plans and bylaws, not by city administrative code. If you own a unit in a condominium, this law does not reach your building. As the coop application clock post documented, condo buyers in New York have had no equivalent statutory protection. That gap remains open.

Market-rate co-ops with ten or more units are the primary target population. That covers a substantial share of the 4,226 co-op buildings in New York City's 15,108-building inventory. Buildings with active sponsor sales pipelines and high application volume are the most likely candidates for early HPD enforcement activity.

The managing agent's specific obligations.

The law names the co-op corporation as the liable entity. In practice, the entity that runs the application process is almost always the managing agent. A co-op board that delegates application processing to its managing agent does not thereby transfer liability away from the co-op corporation; the corporation remains the respondent in an HPD enforcement proceeding, but the managing agent is the operational point where the clock is either tracked or missed.

What that means in practice: the managing agent must now maintain a dated intake log that records the exact date each application arrives. The 15-day acknowledgment window starts from that date, not from when the board next convenes or when the managing agent circulates the file to board members. The managing agent must also have a procedure for sending dual-format acknowledgments (email and registered or certified mail) within the 15-day window. A verbal confirmation or an email alone does not satisfy the statute.

There is a structural gap worth stating plainly. The managing agent executing this compliance workflow — tracking intake dates, sending registered mail, preparing completeness determinations, managing the 45-day calendar — is a person or firm with no required license, certification, or state examination in New York. As the LL58 liability post covered, a barber in New York needs a state license. The person running the application process for a 200-unit building, under a law that carries $2,000-per-violation OATH penalties, does not. Senate Bill S.71 (Kavanagh) would create managing agent licensure. It has not received a floor vote. LL58 adds a new penalty surface on top of that existing gap.

The summer recess mechanism.

Co-op boards that adopted a written summer recess policy before today may be able to pause the LL58 determination clock during July and August. The July board recess post covered this mechanism in detail. The short version: if a board had a written policy in place before LL58's effective date stating that it does not conduct business during July and/or August, the days falling within the covered recess period may toll the 45-day determination clock.

The operative phrase is "adopted before." A board that attempts to create a recess policy today, after the law has taken effect, cannot use it to extend the deadline on applications submitted on or after July 28. If your building's managing agent did not have a written recess policy in place before today, the full 45-day clock runs from the complete-application date for every application submitted starting today. A board that takes its customary summer recess without a valid written policy and returns in September faces OATH enforcement proceedings on any application that aged past 45 days during its absence.

What LL58 does not require.

LL58 imposes a timeline. It does not impose a disclosure obligation on rejection.

A co-op board that rejects an applicant within the 45-day window does not need to explain why. The rejection letter can say "the board has determined not to approve this application" and nothing more. The board's obligation under LL58 is timing, not transparency. As the rejection-reason post documented, the no-reason-required norm has been a feature of the co-op application process for decades, and LL58 does not change it.

A separate bill, Intro 0774, would require boards to provide written reasons for rejection. That bill, Int. 0774-2026, was introduced in the 2026 council session. It has not received a floor vote. The 2026 Albany reform round-up covers the full list of bills that did not advance before the session closed on June 17.

The combination has a predictable shape from a buyer's standpoint. An applicant rejected without explanation within 45 days has no claim under LL58; the board complied with the statute. An applicant rejected after 45 days has a potential HPD complaint but still no right to know why the rejection was issued. The timeline gap and the transparency gap reinforce each other.

Bottom line.

LL58 creates a defined compliance clock for co-op purchase applications. The timeline is 15 days to acknowledge and assess completeness, 45 days from complete application to determination, with $1,000-to-$2,000 OATH penalties for boards that miss the window. Applications submitted on or after July 28, 2026 are subject to the law.

Boards that have not yet updated their application intake procedures should do so before processing any new submission. Managing agents that do not maintain a dated intake log should not accept applications on informal receipt; every submission needs a timestamped record. Buildings without a written summer recess policy adopted before today cannot use a retroactive recess to extend the deadline clock.

What LL58 does not close: the licensure gap (the managing agent executing this compliance still needs no credential in New York State), the rejection-reason gap (boards still do not need to say why an application was denied), and the condo gap (buyers in condominium units have no equivalent protection). Those three gaps sit alongside the new timeline requirement as the current state of co-op purchase regulation in New York City. The issues index tracks each gap and the legislative vehicles, if any, currently aimed at it.
