NYC Rent Freeze Lawsuit Scrutinizes City Hall Communications

The Rent Guidelines Board voted to freeze rents on more than one million New York City stabilized apartments in June. That unprecedented 0% increase for one- and two-year leases is now being contested in court by landlords who claim the board's process was illegally influenced by Mayor Zohran Mamdani's office. A judge-ordered release of nearly 1,000 documents, spanning 3,000 pages of emails and texts, has intensified the legal battle over the board's independence.

Landlords sued the city and published correspondence between officials and board members. They claim the communications prove Mayor Mamdani, who made a four-year rent freeze a central campaign issue, used the board to execute his political will. The RGB had cited the city's historic vacancy rate and a cost-of-living crisis in its decision. If the judge sides with the landlords, the freeze would be canceled and the RGB would have to restart its process.

Communications under scrutiny

Court filings reveal extensive emails and texts between city officials and RGB members. The search produced 101 emails between RGB Chair Chantella Mitchell and Arvind Sindhwani, the Deputy Chief of Staff to the Deputy Mayor for Housing. Text messages indicate Mitchell and Sindhwani spoke multiple times by phone between February and April, discussing scheduling for hearings and key reports.

On April 3, Sindhwani wrote to Mitchell regarding the RGB’s Price Index of Operating Costs report, a key data point. He stated, 'Sending my PIOC notes now, please take a look before we chat, if at all possible.' Other reports discussed included the RGB’s Income and Expense Study and the Mayor’s True Cost of Living Report. A draft of the RGB’s explanatory statement was sent by Chair Mitchell to Sindhwani on June 16, more than a week before the official vote.

The documents also show texts between Cea Weaver, director of the Mayor's Office to Protect Tenants, and newly appointed RGB member Brandon Mancilla. Weaver encouraged Mancilla to join the board, stating his participation was 'very very critical for us.' Mayor Mamdani also texted Mancilla to congratulate him on his appointment. In one exchange, Mamdani texted, 'Hi Brandon, this is my new work number, Mayor Mamdani.' When Mancilla asked if the mayor wanted to call him back, Mamdani replied, 'No need my man but thank you! Hope you’re well.' The messages do not indicate any further communication.

Last week, Richmond County Supreme Court Judge Brendan Lantry ordered more than two dozen top city officials and RGB members to turn over their phones and emails. The resulting documents appear largely logistical, covering meeting schedules, announcements, and board report data. Nothing in the uploaded court docket shows administration members explicitly pushing for a rent freeze.

Official responses and conflicting narratives

City officials maintain the rent freeze was based on data and conducted with integrity. Matt Rauschenbach, a spokesperson for the mayor, said the level of communication shown is standard. 'This year, communications were limited, non-substantive, and in no way reflect any attempts to influence the outcome of the vote,' Rauschenbach said. He called the plaintiffs' filing 'pure misdirection.'

Steven Banks, the city’s top attorney, wrote that there is 'absolutely no merit' to the accusations and that the process was conducted with 'utmost honesty, integrity, and independence.' He described Sindhwani as the designated City Hall liaison for RGB logistics. Banks also characterized the discovery order as a 'fishing expedition.'

In contrast, attorney Randy Mastro, representing the landlords, called the contacts substantial and shocking. Mastro stated the communications show coordination and collaboration to deliver a preordained outcome promised in Mamdani's campaign. He drew a distinction with his own interactions with the previous administration. 'There is a world of difference between conveying to the Board Chair that the Mayor disagreed with the Board’s decision and orchestrating a sham process with a preordained outcome to do exactly what the Mayor dictated,' Mastro stated.

Mastro is a former first deputy mayor under ex-Mayor Adams and has filed at least five actions against the Mamdani administration. He cited a February text exchange between Mamdani and RGB member Brandon Mancilla among the evidence. The suit was originally filed on Staten Island but was moved to Manhattan state court, where the assigned judge is a former Staten Island GOP chairman.

What happens next

The legal challenge places the historic rent freeze in jeopardy. The freeze took effect recently, meaning lease renewals through October 2027 must remain at last year’s rent price. Mayor Mamdani expressed confidence in the RGB’s independent decision and the Law Department’s defense at a Brooklyn press conference.

He referenced a quote from the rapper Fat Joe, stating, 'You know, Fat Joe once said, “Yesterday’s price is not today’s price.” This is one of the places where it’s not correct.' The future of rent stabilization for over one million apartments now hinges on the court's review of the nearly 1,000 disclosed documents. If the judge sides with the landlords, the freeze would be canceled and the RGB would have to restart its process.
