Mamdani wins rent freeze for stabilized NYC apartments

New York City Mayor Zohran Mamdani delivered on a key campaign promise to freeze rents for many residents.

The Rent Guidelines Board gave him what he sought last night. It froze rents on one-year leases and, for the first time, two-year leases in rent-stabilized apartments. Those units make up roughly 41% of the city’s apartment stock.

“This is a historic victory for New York City tenants,” Mamdani said in a statement. “This is the relief that working people across our city deserve.”

Mamdani campaigned on stronger tenant protections, and the board’s decision gives apartment tenants short-term relief. But it could deepen a crisis already straining the city’s housing supply.

A 2019 state law that strengthened rent stabilization statewide unintentionally took units off the market and has drawn lawsuits. Affordability also depends on preserving what already exists.

Realtor.com senior economist Jake Krimmel said landlords are already dealing with higher energy, insurance and property tax costs.

“Frozen revenues against rising costs is a math problem,” Krimmel said. “Should buildings go underwater operationally, the first casualties are maintenance, capital improvements and vacant units that get held off market rather than re-rented at a loss.”

Vacant units pile up

Thousands of rent-stabilized apartments already sit empty across New York City. Under the 2019 rent stabilization law, rent increases are capped at 3% to 4.5% when a tenant renews or a unit turns over. That limit makes it difficult for landlords to recoup renovation costs before re-renting a vacant apartment.

Census data cited in a federal lawsuit filed last November show at least 26,000 rent-stabilized units were vacant and unavailable to renters. Other estimates put the number closer to 100,000.

A group of New York City landlords sued the state in federal court in November over the 2019 law. They are not challenging rent stabilization for existing tenants. Instead, they argue the law unconstitutionally prevents landlords from charging market rent on vacant, renovated units.

Mamdani’s balancing act

When Mamdani was elected, New York City voters also approved charter amendments in November to speed up affordable housing development.

His administration has celebrated wins on accelerated developments that include affordable housing units. But those units won’t enter the market for two to three years because of construction timelines. The housing push also includes accessory dwelling units that have shorter completion timelines.

A favorable ruling in the landlord lawsuit could unlock thousands of vacant units, although they would no longer be rent-stabilized. Apartment industry economists who have argued against rent stabilization say additional supply alone will hold rent prices in check. Legal analysts give the lawsuit better odds than previous U.S. Supreme Court challenges because it is narrowly focused on vacant units.

“New York needs housing for the future,” Krimmel said, adding that it must come through both new construction and the responsible preservation and modernization of buildings already standing. “Right now, the cost side of that equation is rising faster than either tenants or owners can absorb.”
