- The Rent Guidelines Board voted 7-1 to freeze rents on about 1M stabilized apartments, effective Oct. 1, after 3% and 4.5% increases a year earlier.
- Five small landlords sued in July to nullify the vote, alleging the board manipulated its data, and a judge has ordered City Hall to release communications with the board.
- The board found owner expenses up 5.3% against income up 6.2%, but landlord groups say energy costs and 7.03% mortgage rates have pushed costs higher and strained debt service.
New York City’s rent freeze on about 1 million rent-stabilized apartments took effect Oct. 1, and landlords are fighting it in court while operating costs climb, Commercial Observer reports.
The Rent Guidelines Board voted 7-1 on June 26 to halt increases on one- and two-year leases. A lawsuit now seeks to undo that vote and force the board to take another one.

How the Freeze Happened
Mayor Zohran Mamdani promised the freeze on the campaign trail, and the board delivered it. Last year’s vote allowed 3% on one-year leases and 4.5% on two-year leases, effective Oct. 1, 2025.
Owners who expected relief heading into 2027 got the opposite. The board based its decision on data showing landlord expenses up 5.3% in 2026 and owner income up 6.2%.
Costs Keep Rising
The New York Apartment Association says that math is already stale. In a late-September analysis, the group found oil and gas heating costs running 28% above the board’s estimates for 2027, measured against 2025.
The 30-year mortgage rate is 7.03%, up from 6.3% a year earlier. NYAA CEO Kenny Burgos told Commercial Observer the board overlooks at least 130 expenses imposed by city and state rules, and that city assessments disregard buildings whose costs run far above their benchmark.
Burgos also pointed to bank pullbacks, including Flagstar, as evidence of capital flight from the housing stock. Board spokespeople didn’t respond to Commercial Observer’s request for comment.
City Offers Insurance Relief
In April, the city said it would build a program linking owners to cheaper insurance, with a target of 20,000 homes covered by 2027, rising to 100,000 by 2030.
RLTYco co-founder Dan Kennedy told Commercial Observer insurance may not move the needle since debt service eats up most of owners’ costs. Many landlords lack enough income to pay that debt service, he said, and the city will need other ways to hold rents down without pushing owners into financial trouble.
Inside the Court Fight
Five small landlords with rent-stabilized buildings sued in July. Their attorney, former first deputy mayor Randy Mastro, wants the freeze voided and a new board vote. The suit alleges the board manipulated its own data and that the administration packed the board with loyalists.
In September, the judge told City Hall to hand over its communications with the board to test whether it was improperly influenced. At a hearing on Oct. 13 in front of Justice Brendan Lantry, Mastro asked for access to city officials’ phones.
Corporation Counsel Steven Banks countered that judging normal contact between a mayor and the board would mean examining Adams-era communications too. Mastro himself reportedly communicated with then-chair Doug Apple before the 2025 increase.
Mayors appoint board members as a matter of routine. Still, pro-landlord member Christina Smyth resigned the day of the vote, and turnover let Mamdani choose six of nine members, which has fueled doubts.
Zoom Out
The uncertainty isn’t new. When the rent freeze took effect, CRE Daily reported, it was unclear what would happen to leases signed in the meantime if a judge ruled against it, and landlord-side attorney Sherwin Belkin called it uncharted territory, according to The Real Deal.
Why It Matters
Owners can’t raise rents on about 1 million apartments while insurance, fuel and debt costs rise, which tightens cash flow just as lenders and buyers reassess rent-stabilized assets.
Industry attention is high. At The Only Brooklyn conference, the freeze was one of two topics that dominated, as CRE Daily noted in its recap of the Brooklyn panels.
What’s Next
The court fight is ongoing. A ruling for the landlords would send the question back to the board for another vote. Until then, the freeze stands and owners are carrying costs they can’t pass on.
