New York City Mayor Zohran Mamdani has signed a landmark housing law giving nonprofit organizations and community groups priority when purchasing certain distressed apartment buildings, marking a significant change in how the city approaches affordable housing preservation.
Signed on November 10, 2026, the Community Opportunity to Purchase Act (COPA) aims to prevent tenant displacement, improve deteriorating properties and reduce speculative investment in vulnerable neighborhoods.
The legislation could affect approximately 2,100 properties across New York City’s five boroughs. Under COPA, qualified nonprofit housing organizations, tenant associations and community land trusts will receive an opportunity to purchase eligible residential buildings before they enter the conventional real estate market.
The law primarily covers multifamily buildings containing at least four apartments that have fallen into significant disrepair, along with certain properties subject to affordable housing restrictions.
Supporters argue that these buildings are particularly vulnerable to speculative investors who purchase properties, increase rents or postpone essential maintenance. By allowing community-focused organizations to compete for ownership, city officials hope to preserve affordable apartments and improve living conditions.The legislation establishes a structured process intended to give nonprofit organizations enough time to evaluate properties and arrange financing.
When an eligible building becomes available for sale, qualified organizations must receive notification. They have 20 days to express interest and 70 days to submit a competitive purchase offer. The broader process provides an exclusive 145-day period to pursue an acquisition.
If an owner rejects a nonprofit’s offer and subsequently receives another offer during the following year, eligible organizations may exercise a right of first refusal by matching the competing proposal. Importantly, the legislation does not automatically transfer ownership or require landlords to sell properties below market value.
The city’s Department of Housing Preservation and Development will oversee implementation and determine which organizations qualify. Mamdani presented the legislation as part of his administration’s broader effort to address New York City’s housing affordability crisis.
He argued that too many residents experience deteriorating living conditions while landlords prioritize financial returns over necessary repairs. Supporters believe nonprofit ownership could create more stable housing arrangements and encourage long-term investment in building maintenance.
Council Member Sandy Nurse, who sponsored the legislation, described its approval as the culmination of six years of advocacy by tenants and community organizations. An earlier version of COPA was vetoed by former Mayor Eric Adams in December 2025. The City Council approved revised legislation in October 2026, clearing the way for Mamdani’s signature.
The legislation has generated opposition among property owners and real estate industry representatives. Critics worry that additional purchasing procedures could delay transactions, discourage investment and complicate the sale of financially distressed buildings.
Some argue that nonprofit organizations may struggle to secure financing quickly enough to compete with established private investors. Others question whether the policy could reduce market flexibility without substantially increasing the city’s housing supply.
These concerns highlight the tension between protecting existing tenants and maintaining an active real estate investment market. COPA complements Mamdani’s broader housing agenda, which aims to construct 200,000 affordable homes and preserve another 200,000 over the next decade.
His administration has also committed $22 billion in affordable housing capital over five years. However, the law’s success will depend on effective implementation, adequate financing and the capacity of nonprofit organizations to manage acquired properties.
The legislation represents an effort to shift housing preservation toward community-based ownership. For tenants, it could provide greater protection against displacement and deteriorating conditions. For investors and property owners, it introduces new requirements that may reshape transactions involving distressed residential buildings.
New York City’s new housing law reflects a growing debate over whether affordable housing should be treated primarily as a financial investment or as essential community infrastructure. Its long-term impact will depend on how successfully nonprofit ownership improves housing stability without discouraging necessary investment.
