- Once-skeptical developers now say City Hall is the friendliest in years for building housing, as Mayor Mamdani pairs landlord restrictions with development incentives.
- Manhattan’s rental vacancy rate hit 1.6% in July, extending a shortage that pushed the citywide rate to 1.4% in 2024, the lowest since the late 1960s.
- Proposed housing units surged to nearly 17,000 in the first quarter of 2026, about 250% above the average pace since 2008, signaling accelerating momentum.
New York City Mayor Zohran Mamdani has turned developers into unlikely allies for his citywide housing push, according to The Economist.
After campaigning against landlords and once opposing new construction as a state assemblyman, Mamdani has embraced private developers as partners in solving the city’s housing shortage. Once-wary homebuilders now say City Hall hasn’t been this friendly to new construction in years.

From Foe to Ally
Mamdani built his mayoral campaign around concerns over the city’s cost of living. He promised to freeze rents on the 1 million apartments regulated by the city.
As a state assemblyman, he also criticized a proposed development. He argued it could “accelerate…displacement.”
Developers took the threat seriously. One email circulated among homebuilders last year warned that “the financial capital of the world risks being handed over to a socialist.”
But two weeks before the mayoral primary, Mamdani told The New York Times he had changed his mind. He said the private market has “a very important role to be played” in building housing.
Alex Armlovich of the Niskanen Center describes the resulting bargain as trading socialism on old housing for markets on new housing.
The Details
As mayor, Mamdani has maintained his focus on tenant protections. In June, a city board approved a 0% rent increase for rent-stabilized apartments starting in October.
City Hall has also encouraged tenants to organize. It has held “rental ripoff” hearings for renter complaints.
On development, Mamdani created task forces to identify delays in affordable housing approvals. He also created a task force to find city-owned sites for redevelopment.
In May, he released a plan to build 200,000 affordable apartments over a decade. The plan would loosen regulations and offer incentives to for-profit developers that renovate public housing.
In February, Mamdani traveled to Washington to lobby President Trump for $21 billion in federal funding for Sunnyside Yard. The long-delayed Queens housing megaproject had faced opposition from Representative Alexandria Ocasio-Cortez in 2019.
Trump has yet to commit the money. Still, the trip showed Mamdani’s willingness to seek federal support for new construction.
Zooming Out
The rent freeze fits into a broader pattern of pressure on landlords. At the same time, Mamdani has welcomed developers.
That tension is playing out in a legal challenge that landlords brought against the city’s rent-freeze push.
The debate comes amid a severe housing supply crunch. New York’s rental vacancy rate was 1.4% in 2024, according to the most recent official data.
That was the lowest level since the late 1960s. Corcoran Group data put Manhattan’s vacancy rate at 1.6% in July.
The city has also started losing population again after a post-pandemic rebound.
Mamdani’s housing agenda also has support from outside City Hall. According to The Economist, state reforms to environmental review rules and ballot measures could help speed up approvals.
Why It Matters
“We have a very friendly City Hall when it comes to building housing, which is phenomenal,” said Carlo Scissura, president of the New York Building Congress.
“The mayor is in a good place on this,” added Steven Fulop, president of the Partnership for New York.
Proposed housing units jumped to nearly 17,000 in the first quarter of 2026. City data cited by The Economist puts that figure about 250% above the average pace since 2008.
Molly Wasow Park of the NYC Housing Partnership called the mayor’s 200,000-unit affordability plan “really ambitious, really aggressive.”
The strategy builds on Mamdani’s other development moves. These include his rezoning plan for Central Brooklyn.
The approach also signals that City Hall sees private capital as essential to its affordability targets. It does not necessarily view that capital as a rival to those goals.
What’s Next
Deputy Mayor for Housing Leila Bozorg says City Hall plans to push development near subway stations next.
However, delivering all 200,000 promised affordable units could require public funding. Potential sources include Washington, Albany, or local bonds.
The tension between the city’s landlord and developer policies also remains unresolved.
“We would love for you to build, but once you build…” said Basha Gerhards of the Real Estate Board of New York.
Gerhards then added, diplomatically, that “people have added various adjectives.”
Bozorg counters that building housing is “a long-term goal.” Meanwhile, the city continues to manage a near-term imbalance of power between tenants and landlords.
