Landlords ask a court to strike down the rent freeze

Seven landlord entities filed an Article 78 petition in Richmond County Supreme Court on 22 July. The case asks the court to annul Rent Guidelines Board Order 58, which set zero percent increases for covered one year and two year rent stabilized leases beginning between 1 October 2026 and 30 September 2027.

The petitioners say the board reached a predetermined result, did not act independently and failed to weigh building costs rationally. They also challenge the board's treatment of operating cost, income and debt information. Those statements are the landlords' case, not findings made by a judge.

City Hall says the board considered the relevant data and the pressures facing both tenants and owners. The Law Department is preparing to defend the decision. Until a court orders otherwise, tenants should use Order 58 and current NYC311 guidance rather than assume that the lawsuit has changed their renewal rate.

What the landlords allege

The petition says Mayor Mamdani appointed members who were already inclined to support the campaign promise and used city offices to encourage tenant participation at board hearings. It argues that this compromised a body that is required to exercise its own judgment.

The filing also says the board's own operating cost index showed costs rising 5.3 percent in the latest year and projected further increases. It argues that the board overstated owner income, understated expenses and gave too little weight to debt service and the condition of heavily regulated buildings.

What is established now

Order 58 is an official Rent Guidelines Board order dated 25 June 2026. It sets a zero percent adjustment for covered one year and two year apartment and loft leases beginning from 1 October 2026 through 30 September 2027.

The board is a nine member body with tenant, owner and public representatives. The legal dispute is about whether its process and reasoning met New York law. The lawsuit does not by itself suspend the order or decide that the mayor acted unlawfully.

The public argument on both sides

Owners say insurance, utilities, taxes, repairs and financing have risen and that a uniform freeze may weaken maintenance in financially stressed buildings. The court filing asks for a new process that produces rent increases.

Tenant advocates say households needed relief after repeated increases and that board data also showed improved citywide net operating income. The city's defence is expected to focus on the full administrative record, including tenant affordability as well as owner costs.

What tenants and owners should do

Tenants receiving a renewal should check the lease start date, confirm that the apartment is rent stabilized and compare the proposed increase with current NYC311 guidance. Individual rent history and overcharge questions belong with New York State Homes and Community Renewal or a qualified housing adviser.

Owners should follow the court docket and official board guidance. A later court order could change the position, but political claims and press headlines do not replace a filed judgment or updated city rule.
