Key takeaways: New York City’s 0% rent freeze for roughly a million rent-stabilized apartments took effect on October 1, 2026, and it covers one-year and two-year leases that begin through September 30, 2027. Landlords are already sending renewal offers at frozen rents while suing to overturn the vote, and a Manhattan judge has ordered City Hall to hand over its communications with the Rent Guidelines Board. For Brooklyn multifamily owners, rent growth is now a court case, not a spreadsheet assumption.
A zero percent year for stabilized rents
The Rent Guidelines Board voted 7 to 1 on June 25 to hold increases at 0% for both one-year and two-year leases. It is the first two-year freeze in the board’s history.
The order covers roughly a million rent-stabilized apartments across the city. It applies to leases that begin between October 1, 2026 and September 30, 2027.
The freeze rolls in gradually. As each lease expires, the owner must offer a renewal at the frozen rent, and those offers go out at least 90 days before expiration.
Renewal offers at frozen rents are already landing in mailboxes, and tenants are signing them. Whatever the courts decide later, a year of flat regulated revenue is already being written into leases.
Operating costs did not get the same memo. Insurance, property taxes, fuel, and repairs keep climbing, which squeezes the spread on every stabilized building in the borough.
Brooklyn investors feel it first
A large share of the city’s stabilized housing sits in Brooklyn, from Crown Heights and Flatbush to Williamsburg. That concentration is why the freeze dominated the borough’s own industry gathering this month.
At the Only Brooklyn Real Estate Conference in Downtown Brooklyn, the “Future of Brooklyn Multifamily” panel took the freeze head-on. As Commercial Observer reported, panelists from firms including Z+G Property Group, Camber Property Group, and PH Realty Capital questioned the legality of the vote and warned about the strain on affordable housing.
TerraCRG’s Matthew Cosentino argued the freeze may ultimately be found unlawful. He also cautioned that even a reversal would likely produce only a small increase, not enough to change the math for owners of thousands of units.
The timing adds to the whiplash. Brooklyn’s median sale price just hit a record $1.2 million in the third quarter, up 14.3% in a year, even as the national market sits at a 13-year extreme with sellers outnumbering buyers by 63%.
Investors are still paying up for assets with a growth story, the way buyers did in the recent $32 million Evanston apartment deal. Stabilized Brooklyn buildings now have to be priced on frozen income instead.
The court fight that could unwind it
A group of landlords sued in July, asking the court to annul the board’s vote. The case argues the outcome was decided before the board ever weighed the owners’ financial data.
Two facts give the claim its edge. Mayor Zohran Mamdani, who campaigned on a promise to freeze the rent, appointed six of the board’s nine members in February, and board member Christina Smyth resigned before the vote, saying the result was predetermined.
Judge Brendan Lantry has so far declined to halt the freeze. In September, he ordered the city to turn over written communications between City Hall and the board covering January through the June vote.
The messiest question is what happens to leases already signed at frozen rents if the freeze falls. Landlord attorney Sherwin Belkin calls it uncharted territory, and the city would likely appeal any loss, adding months of uncertainty.
What Brooklyn owners should watch
The discovery fight comes first, and a final ruling could take months. Until then, the frozen renewals being signed every week are binding contracts.
The city is pushing the other side of the ledger at the same time. Deputy Mayor Leila Bozorg used the same conference to promote a $5.6 billion housing plan aimed at creating 200,000 affordable homes and preserving 200,000 more, plus faster land-use reviews in 12 council districts.
That supply-versus-regulation tension is playing out nationally, too, in projects like the Dallas office property being flipped into mixed-income housing.
For underwriting, the practical move is simple. Price stabilized units at 0% growth for this lease year, document every renewal offer, and treat any post-lawsuit upside as a bonus, not a basis for the purchase price.
