Seven NYC landlords sue Mayor Mamdani over rent freeze for stabilized apartments

A coalition of seven New York City landlords filed a lawsuit Wednesday challenging the city's recently approved rent freeze for rent-stabilized apartments.

The Rent Freeze Policy

The Rent Guidelines Board (RGB) voted 7–1 in late June to freeze rents for one- and two-year leases signed between October 1, 2026, and September 30, 2027. The decision affects approximately 1 million rent-stabilized apartments across the city.

Landlords' Legal Challenge

The lawsuit alleges that the RGB vote was the product of a "sham process with a predetermined outcome" that will place a financial burden on property owners.

Mayor's Affordability Goal

Freezing rent had been a key affordability pledge for Mayor Zohran Mamdani since the early days of his campaign. While a single landlord lawsuit is unlikely to overturn the policy, the mayor may face challenges maintaining the freeze beyond a year or two. Past attempts to cap rents in New York City and other cities — including St. Paul, Minnesota — have struggled to sustain the necessary economic support or political will over the long term.

Mayor's Office spokesperson Matt Rauschenbach said the city's law department is prepared to defend the policy in court, adding that "the Mamdani administration remains committed to the success of the rent stabilization system, which has prevented displacement and provided stability to generations of New Yorkers."

Historical Precedent

Similar rent freezes have faced legal challenges before:

• St. Paul, Minnesota won a lawsuit against landlords in 2023 after a challenge to its 3% annual rent cap ordinance was dismissed.
• New York City under Mayor Bill de Blasio successfully implemented one-year rent freezes for leases in 2015, 2016, and 2020. The 2016 freeze was challenged in court but the lawsuit was unsuccessful.

Legal Arguments

Deborah Riegel of Rosenberg & Estis, co-counsel for the landlord plaintiffs, told Business Insider that the 2016 lawsuit centered on whether the RGB could consider tenant affordability in granting a freeze. The current lawsuit presents a different argument, she said, based on rising costs for landlords and alleged misuse of the city's bureaucratic approval process.

"Whether or not you consider tenant affordability, your data on the cost side is so clear — it is so irrefutable that owners' costs are increasing," Riegel said, noting that other city-controlled costs like local property taxes are also rising. "They're still taking the position that the owners should absorb those increases without any corresponding increase in their income."

Financial Risks

A June Moody's Ratings report found that a hypothetical five-year rent freeze could put 6% of NYC multifamily loans in commercial mortgage-backed securities at risk of default.

Next Steps

The city and the landlords are scheduled to appear before a judge in September.

Potential Market Impact

The landlords' suit argues that a rent freeze would make it difficult for owners to survive amid rising costs.

Jake Krimmel, a senior economist at Realtor.com, said the debate is not about "tenants versus landlords" but about analyzing the policy's effects on the rental market. Key observations include:

• Rent-stabilized tenants will benefit directly.
• Market-rate apartments will face increased pressure, as New York City's housing supply is low and stabilized tenants will be less willing to move out.
• New construction is unlikely to be discouraged, as the freeze applies only to existing units.

Market pressure will also depend on how landlords adjust to rising operational costs — including high energy prices, property taxes, insurance, and general inflation. Landlords with both rent-stabilized and market-rate units may raise rents on market-rate apartments to offset costs. Those who primarily own rent-stabilized units might reduce maintenance or leave apartments vacant, as it can be less costly than managing tenants.

Similar ripple effects occurred in St. Paul and surrounding areas, prompting the city to roll back its rent cap.

"Ultimately, there's a balancing act," Krimmel said. "The landlord is going to have to balance the income that they get coming in."
