Mamdani makes it clear. They are no longer “your homes”, even if you own it, in a move to abolish private property.
Mayor Zohran Mamdani has signed a new housing law giving selected nonprofit organizations priority when certain private apartment buildings are sold. Supporters call it affordable housing reform. Critics see another expansion of government control over private property.
New York City has taken another significant step toward changing how private property can be bought and sold.
On November 10, Mayor Zohran Mamdani signed the Community Opportunity to Purchase Act (COPA) into law, giving city-approved nonprofit organizations preferential purchasing rights over certain privately owned apartment buildings.
The legislation, championed by Council Member Sandy Nurse, passed the City Council on October 22 by a vote of 38–9.
Supporters say the law will protect tenants from negligent landlords, prevent displacement and preserve affordable housing. But pro-liberty opponents argue it creates a troubling precedent: the government can now deciding who gets the first opportunity to purchase property that belongs to someone else.
What exactly is COPA?
Under COPA, owners of certain multifamily buildings must provide qualified nonprofit organizations with an opportunity to purchase their property before completing a sale to another buyer.
The law primarily targets buildings with four or more residential units that meet specific distress criteria or are covered by qualifying city-managed affordable housing agreements.
Another big issue with the plan is that the city is the one creating the criteria and can force multiple summons on buildings to make them qualify for being “distressed”, targeting landlords who the city doesn’t like and forcing them into a sale.
Here's what that means in practice:
Government-approved buyers get priority. The city's Department of Housing Preservation and Development will certify nonprofit organizations eligible to participate. This means Mamdani’s friends in non-profits who often receive city funding and most likely make donations to his campaign will be the first to get access.
Property sales face additional procedures. Qualified organizations receive an initial period to express interest and submit purchase offers.
Nonprofits can match competing offers. In qualifying circumstances, organizations receive a right of first refusal when another buyer makes an acceptable offer.
Owners face substantial penalties. Violations of the notification requirements can result in penalties of up to 15% of the sale price.
The law is expected to initially affect approximately 2,100 buildings, substantially fewer than the roughly 10,000 properties contemplated under an earlier proposal. Its provisions are scheduled to take effect one year after enactment.
The Bigger Question: Who Really Controls Private Property?
Private property ownership has traditionally included several fundamental rights: the ability to possess, use, improve and sell an asset, subject to applicable laws.
COPA introduces another restriction on that final right.
A building owner who wants to sell an eligible property must now navigate a process that gives a government-certified class of purchasers preferential access. This means if you’re a non-government organization which is potentially close to the Mayor, you get first dibs on units.
Critics argue that this changes the relationship between private owners and City Hall.
Rather than simply regulating the condition and safety of buildings, the city is intervening in the process of determining who gets an opportunity to own them.
The concern is not that COPA immediately eliminates private ownership.
The concern is whether laws like COPA establish a framework through which government increasingly controls the decisions traditionally reserved for property owners.
From 2,100 Buildings to What Comes Next?
The latest version of COPA is narrower than the original legislation, which was vetoed by former Mayor Eric Adams in December 2025.
Adams argued that the earlier proposal went too far by restricting the potential buyers of buildings, including some with relatively minor maintenance problems.
The revised law removes several controversial provisions and prevents the housing department from unilaterally expanding covered property categories through administrative rules.
Those limitations matter.
Nevertheless, opponents raise a broader concern about legislative precedent.
If New York can require owners of distressed apartment buildings to offer preferential purchasing opportunities to approved organizations, could future lawmakers extend similar requirements to additional types of housing?
Such an expansion would require further legal or legislative action. It is not something the current law automatically authorizes.
But the question illustrates why property-rights advocates are paying attention.
What begins as a targeted housing preservation program could become a model for more extensive government involvement in private real estate transactions.
The Nonprofit Question: Who Gets to Own New York?
One of COPA's most consequential features is the power it gives to organizations certified by the city.
These nonprofits, community land trusts and other qualified entities must demonstrate experience and financial capacity to acquire and manage affordable housing.
Supporters believe these organizations can provide more stable, community-focused ownership than speculative investors.
But critics question whether preferential access should depend on government certification rather than open competition among qualified buyers.
There are also practical concerns.
Nonprofits still need money to purchase buildings, repair aging infrastructure, pay operating expenses and maintain safe housing.
A nonprofit designation does not automatically guarantee better property management or lower maintenance costs.
Even the New York City Council's review of the legislation acknowledged that nonprofit purchasers can face substantial financing challenges, which means they will need to get even more money from the government to purchase and maintain buildings, money that comes from tax payer dollars.
Affordable Housing or Greater Government Intervention?
New York's housing affordability crisis is real.
High rents, deteriorating buildings, housing shortages and displacement have created enormous pressure on working families.
COPA supporters argue that giving community organizations a better chance to purchase vulnerable buildings can prevent further deterioration and keep existing affordable apartments available.
They point to similar policies in San Francisco as evidence that nonprofit acquisitions can preserve housing and protect tenants.
Opponents, including organizations representing smaller property owners, argue that additional sales restrictions may discourage investment, complicate transactions and reduce the value of affected buildings.
They also contend that rising insurance, maintenance, tax and financing costs deserve more attention than restrictions on property sales.
These are competing theories about how to improve housing affordability.
One emphasizes preserving existing buildings through nonprofit ownership. The other emphasizes maintaining private investment incentives and owners' flexibility in a difficult housing market.
The slow creep toward a different housing system
The debate over COPA is ultimately about more than 2,100 buildings.
It raises a fundamental question about the future of private property in New York City.
Why should the government be allowed to intervene in a transaction between a willing seller and a willing buyer?
At what point do restrictions intended to protect tenants become excessive limitations on ownership?
And how should New York balance the legitimate need for affordable housing against the rights of people who have invested in, maintained and owned property for generations?
For critics, COPA represents an incremental shift toward a housing system in which government-approved organizations receive advantages over other private purchasers.
For supporters, it represents a limited intervention designed to preserve affordable homes without abolishing private ownership or preventing voluntary sales.
COPA does not mark the end of private property in New York City. But it does create a new legal precedent for government-directed purchasing priorities.
Whether that precedent remains narrowly focused on distressed and regulated housing, or eventually inspires broader restrictions, will be an important question for New Yorkers to watch.
The future of property ownership may not be determined by one sweeping law. It may instead be shaped by a series of smaller decisions about who has the right to buy, sell and control the buildings that make up the city.
