- New York City’s freeze on rent-stabilized apartments applies to leases starting on or after Oct. 1, 2026, while landlords continue challenging it in court.
- Landlords are already sending renewal offers at frozen rents and tenants are signing them, raising questions about retroactive increases if the court rules against the city.
- With discovery ordered and appeals likely, the case could take months, leaving owners of stabilized buildings unable to underwrite near-term rent income with confidence.
New York City’s rent freeze for rent-stabilized apartments took effect Oct. 1, 2026, even as a group of landlords continues to fight it in court, according to The Real Deal.
What happens to leases signed in the meantime, or if the judge rules against the freeze, remains unclear. Landlord-side attorney Sherwin Belkin called it uncharted territory with countless possible outcomes.

How the NYC Rent Freeze Got Here
Mayor Zohran Mamdani campaigned on a rent freeze, and the Rent Guidelines Board voted in June to freeze rents on stabilized apartments. The order applies to leases that take effect on or after Oct. 1.
The freeze rolls out gradually. As leases expire, landlords must offer renewals at frozen rent levels, and they’re required to send those offers at least 90 days before expiration.
The Details
Judge Brendan Lantry has so far declined to halt the freeze or carry over the prior year’s allowable increases, saying at a hearing the week of Sept. 21 that he didn’t see authority to apply a past year’s increase to this year. Landlord attorneys discussed whether the court could pause the renewal-offer requirement, but haven’t formally requested that relief.
Meanwhile, landlords have started delivering renewal offers at frozen rents and tenants are signing them. Belkin said those leases are binding, but if the judge sends the decision back to the board, he’ll likely need to address whether landlords can break those contracts or recover increases retroactively.
A Different Fight Than the De Blasio Era
When landlords sued over a rent freeze under Mayor Bill de Blasio, the judge took about seven months to rule and sided with the city, sidestepping the lease renewal questions.
This time, landlords may have better odds. Lantry has ordered discovery, a rare step in this type of case, and has flagged several aspects of the board’s decision he found peculiar, building on earlier signs that the rent freeze challenge would face close scrutiny.
Why It Matters
For owners of stabilized buildings, the uncertainty makes near-term rent income hard to underwrite. Herrick litigation partner Andrew Wagner said he expects any increase that results from the case to be retroactive, meaning tenants could owe back rent for months already paid.
Collecting those amounts may not be practical, as Wagner questioned whether landlords would sue to recover a few hundred dollars. The added uncertainty compounds concerns that the freeze could pressure multifamily bank credit tied to stabilized properties.
What’s Next
The case will likely take several more months, especially if the losing side appeals. Belkin noted that a city notice of appeal would automatically stay any ruling against the freeze, adding another layer of delay.
Even a landlord win would bring disruption to the rental market, with Belkin predicting it will be a mess.
