Landlord Suit Seeks Depositions After City Emails Reveal Rent Freeze Coordination

Key points

• The 0% rent increase for one- and two-year leases in rent-stabilized apartments began on October 1, 2026.
• Attorney Randy Mastro, representing landlords, submitted emails and texts as evidence in his lawsuit to block the freeze.
• The documents show coordination between the mayor’s office and board members regarding appointments, meeting agendas, and presentations on the 'True Cost of Living.'
• Mastro argues these communications prove the Rent Guidelines Board acted as a puppet for the mayor, violating its independence.
• Mamdani’s office counters that the board is independent and cites past instances where Mastro lobbied for lower rent increases.
• The landlord’s attorney is asking Judge Brendan Lantry to compel depositions of 13 city officials and board members.

Background

This dispute follows a series of legal challenges to the Rent Guidelines Board’s decision in June 2026 to implement the first-ever freeze on two-year leases. Previous coverage noted that a Manhattan judge had already ordered the release of communications between City Hall and the board in September 2026, narrowing the scope of discovery to written exchanges between January 1 and June 25. The current development involves the actual submission of these documents and the push for live testimony.

How outlets are covering it

Gothamist reports that the submitted emails and texts show 'shocking' coordination, including the mayor greeting a new board member and staff arranging presentations on living costs that were not previously considered. The outlet highlights Mastro’s argument that this coordination constitutes a 'sham process.' In contrast, Mamdani’s office, as reported by Gothamist, defends the board’s independence and points to Mastro’s own past lobbying efforts as evidence of his bias. NBC 4 New York provides a broader context of October 2026 rule changes, confirming the 0% increase for 1 million units but does not delve into the legal dispute or the specific content of the released communications, focusing instead on the practical impact of the freeze on tenants.

Why it matters

The outcome of this legal challenge could set a precedent for the independence of the Rent Guidelines Board and the extent to which city officials can influence housing policy. If the court rules that the board was improperly influenced, the rent freeze could be overturned, potentially leading to significant rent increases for millions of New Yorkers. Conversely, if the freeze stands, it will remain a key policy achievement of the Mamdani administration, impacting the cost of living for a large segment of the city's population.

What to watch

The next step is for Judge Brendan Lantry to rule on Mastro’s request to compel depositions of the 13 city officials and board members. If granted, these depositions could provide further evidence of collusion or independence. The court will also need to decide whether to block the rent freeze or require the board to vote again. Tenants are advised to contact the city’s tenant helpline to confirm if the freeze applies to their specific lease.
