Simple Content Summary: New York City Mayor Zohran Mamdani signed the Community Opportunity to Purchase Act on November 10, creating a first-purchase opportunity for qualified nonprofit organizations seeking certain distressed or affordability-restricted apartment buildings. The law is expected to take effect in November 2027.
New York City Mayor Zohran Mamdani signed the Community Opportunity to Purchase Act (COPA) on Tuesday, November 10, turning a long-debated housing-preservation proposal into law and establishing a new process for the sale of certain multifamily properties.
The signing is a new development following the City Council’s October 22 passage of a revised version of the measure. The law is designed to give qualified nonprofit housing organizations and community land trusts a meaningful opportunity to acquire eligible properties before a sale closes with another buyer.
Which buildings are affected?
The enacted measure generally concerns residential buildings with at least four units that meet specific distress or affordability-related conditions. Those conditions can include serious unresolved housing violations, documented tenant harassment or qualifying affordability restrictions. Not every apartment building is covered, and owner-occupied properties with five or fewer units are exempt.
Owners of covered properties must provide notice to the city’s Department of Housing Preservation and Development and eligible organizations when planning a sale. The measure does not require owners to sell and does not guarantee a nonprofit buyer will secure the property.
Purchase rights could change transaction planning
The mayor’s signing remarks describe 20 days to express interest and 70 days to make an offer. The Mayor’s Office describes a broader 145-day purchase process, with a right to match qualifying competing offers during the following year. These periods serve different stages of the transaction, and the enacted law governs their application. The precise statutory timetable, exceptions and notice obligations will be important for owners, brokers, attorneys and lenders to examine before affected transactions begin.
While the law provides a new route to community ownership, qualified organizations will still need acquisition financing and the capacity to manage the properties. Supporters say the process can preserve affordability and reduce displacement. Opponents warn of additional transaction complexity and argue that operating-cost pressures on owners also need attention.
Implementation comes next
The legislation is expected to take effect in November 2027, giving the city time to develop rules and certify qualified purchasing organizations. Owners and investors should watch HPD’s implementation guidance rather than assume the new procedures apply immediately to current sales.
WRE previously covered the City Council’s passage of COPA. The mayor’s signature completes a separate step in the legislative process.
