New York is funding 300 new affordable co-op units by 2028. The governance rules have not changed.

In November 2025, the New York City Comptroller found that the city's primary affordable co-op conversion program had completed 13 buildings since 2012, while 81 of 113 buildings in the pipeline had not converted, with delays averaging 6 to 11 years. Six months later, Mayor Mamdani's "Block by Block" housing plan announced "Our Home": $75 million in city loans to add 300 new affordable co-op units by the end of fiscal year 2028. New York still requires no reserve study, licenses no managing agent, and has no state enforcement forum for co-op governance disputes.

What the Comptroller audit found.

The NYC Comptroller's audit of HPD's Affordable Neighborhood Cooperative Program, released in November 2025, examined the Tenant Interim Lease program, which moves city-owned occupied rental buildings toward resident co-op ownership. The numbers were specific: 81 of 113 buildings were still awaiting conversion. Of those, 45 buildings containing 802 units had no assigned developer at all. The 13 buildings that did complete conversion exceeded HPD's own benchmarks by 15 to 87 months, on processes HPD estimated would take 6 to 11 years.

One group of residents entered the Tenant Interim Lease program in September 1997. As of the audit date, they still had no assigned developer. The Comptroller recommended that HPD build a centralized tracking mechanism to identify recurring causes of delay. HPD accepted the recommendation. The audit identified key causes of delay: staffing shortages, difficulties securing financing, outdated data management systems, and inadequate interagency coordination. The governance capacity of the tenant organizations themselves is the structural gap the city has the least institutional capacity to address, because New York has no co-op governance standard to enforce.

"Our Home" scales the pipeline.

On May 26, 2026, Mayor Mamdani released "Block by Block: The Housing Plan for a New Era." Among its affordable homeownership commitments: double the Open Door program and launch "Our Home," a new pipeline providing $75 million in city loans to help renters buy and convert their buildings into co-ops. HPD's projection: 300 new affordable co-op units in fiscal years 2027 and 2028.

In June 2026, the mayor cut the ribbon at ANCP Morningside, where HPD and its partners converted formerly city-owned rental buildings into 36 permanently affordable homeownership opportunities. That project represents the model "Our Home" intends to replicate at scale. The program would need to produce 150 units per year to meet the two-year target. ANCP has historically converted roughly one building per year since 2012.

ANCP's published terms provide up to $200,000 per unit in city capital subsidy, alongside construction and permanent financing from other sources. At $200,000 per unit and 300 units, the city subsidy component alone approaches $60 million. The governance framework those 300 units will operate under once conversion closes is not specified in the program terms. It does not exist in New York statute.

The governance rules these co-ops inherit.

New York's Condominium Act (Real Property Law §339 et seq.) requires no reserve fund and no reserve study for any condominium or cooperative. The Business Corporation Law, which governs co-ops as housing corporations, contains no reserve standard. No New York statute requires a co-op board to commission a professional assessment of its capital needs before or after conversion, to maintain a separate replacement reserve account, or to produce an annual report to shareholders on the building's financial condition.

The managing agent who oversees the building's finances, administers vendor contracts, and coordinates compliance with Local Law 97, Local Law 11, and other city mandates needs no state license. S.71, the managing agent registration bill, last received a committee hearing in the 2009 legislative session. It has no identified sponsor for the 2027 session.

The consequence is documented. In September 2025, Attorney General James, the Adams administration, and HPD jointly announced a technical assistance pilot for low-income HDFC co-op owners across New York City. The program's basis: the AG's office had found that a high number of HDFC co-ops were at high risk of financial and physical failure. The remedy: $750,000 of settlement funds, sufficient for 20 to 30 buildings. There are more than 1,000 HDFC co-ops in HPD's portfolio.

What other states require at conversion.

The enforcement path when governance fails.

As documented on this site, the AG's Real Estate Finance Bureau is authorized to enforce offering plan compliance under the Martin Act and Real Property Law Article 9-B. It is not authorized to intervene when a co-op board ignores its own bylaws, mismanages reserve funds, or fails to maintain capital accounts. That boundary is structural: the statute authorizes post-offering-plan enforcement for fraud in the inducement, not for governance failures after the co-op is operating.

For unit owners in affordable co-ops, the civil court alternative is available in principle and unreachable in practice. A shareholder derivative action under Business Corporation Law §626 requires standing, attorney fees the plaintiff generally cannot recover, and years of litigation. In affordable co-ops where shareholders paid below-market prices, that cost-benefit calculation rarely resolves in favor of suing. The CTAP pilot acknowledged this gap: the program provides technical assistance because enforcement is not available.

The Comptroller audit identified governance capacity as a barrier before conversion closes, not only after. Buildings that struggled to maintain a functioning tenant organization through a six-to-eleven-year pipeline are the same buildings that will face governance instability once they operate as co-ops without a state standard, without a licensed managing agent, and without an enforcement path. New York has no mechanism to assess whether a newly converted co-op has the capacity to sustain itself before $75 million in city loans closes.

Bottom line.

New York City is scaling its affordable co-op creation pipeline at the same time its own Comptroller audit documented governance failure as a conversion barrier and its own AG's office used settlement money to rescue 20 to 30 buildings from a portfolio of more than 1,000. "Our Home" will add 300 units to a program that has completed 13 buildings since 2012. The new units will operate under the same rules as those 13: no reserve requirement, no licensed managing agent, no enforcement forum. That is not a structural inevitability. Massachusetts requires reserve studies and quarterly financial reporting. Oregon has banned votes to leave reserve accounts underfunded since 1999. Washington D.C. licensed community managers and codified their fiduciary duty that same year. It is a policy choice New York has renewed by omission, at $75 million per renewal.
