Signed into law by Mayor Adams in late 2024, the Community Opportunity to Purchase Act (COPA) will reshape how multifamily buildings change hands in New York City, with full implementation expected by 2027. If you own a building with six or more units, or plan to buy one, this law directly affects your timeline, your closing process, and your legal obligations.
In my 25 years working multifamily sales across all five boroughs, I have watched tenant protection laws come and go, but COPA carries more structural weight than anything since rent stabilization expanded in 2019. The mechanics are borrowed from Washington DC's TOPA, a law that has preserved roughly 5,000 affordable units since 1980.
What COPA Actually Does
COPA creates a right of first refusal for qualified entities when a covered building is listed for sale. Qualified entities include tenant associations, nonprofit housing organizations, HDFCs, and designated community land trusts. The seller must give these entities a formal opportunity to purchase at the same price and terms as any accepted third-party offer.
