New York City’s recently enacted rent freeze policy, championed by Mayor Mamdani, is facing mounting legal challenges and criticism from landlords and housing experts who warn of unintended consequences for both tenants and property owners. The freeze, passed by a 7-1 vote of the Rent Guidelines Board (RGB) on June 25, 2026, prohibits rent increases on one- and two-year leases for approximately one million rent-stabilized units from October 1, 2026, through September 30, 2027. A subsequent vote will determine whether the freeze extends into 2028.

Critics argue the decision, a key promise from Mamdani’s campaign, disregards rising operating costs faced by landlords. Real estate lawyer Massimo D’Angelo noted that building owners could contest the freeze on grounds that it fails to account for higher expenses and disrupts their investment expectations. He further suggested landlords might argue that the RGB neglected due process by overlooking data on increased building and insurance costs prior to enacting the freeze. One RGB member, Christina Smyth — appointed by former Mayor Eric Adams and a landlord advocate — resigned in protest, claiming the board abandoned its fact-finding role to fulfill a preordained political mandate. Smyth accused the RGB of ignoring evidence of landlords' rising expenses and criticized the move as politically motivated.

Landlords themselves have expressed concerns that the freeze will exacerbate financial strains, leading some to consider selling their properties or reducing maintenance. Violet Zharku, who owns several rent-stabilized buildings in Queens, said the freeze comes amid ongoing financial distress despite recent investments in her properties. Similarly, Frank Velovic, a property owner and doorman, called the policy a “disaster,” emphasizing that limiting landlord income undermines their ability to maintain buildings, potentially degrading housing quality for tenants.

Supporters of the freeze view it as a necessary measure to protect renters amid rising living costs and housing insecurity. The policy aligns with Mayor Mamdani’s advocacy for tenant protections and reflects a broader push for affordability in a city grappling with housing challenges. However, housing data indicates that approximately 41% of stabilized units are occupied by single adults without children, and about 30% of tenants earn over $100,000 annually, raising questions about the policy’s reach and effectiveness for lower-income households.

Beyond rent-stabilized units, experts warn that the freeze may prompt landlords to increase rents on market-rate apartments to offset lost revenue, potentially driving up rents for tenants not covered by stabilization laws. This dynamic could limit mobility within the rental market and reduce vacancy rates, complicating access to affordable housing for new or relocating residents.

The legality of the freeze is expected to be vigorously contested in court, with observers noting the potential for the issue to reach the U.S. Supreme Court. Previous rulings have upheld rent regulations when based on decisions by ostensibly independent bodies like the RGB. However, allegations that political influence dictated the recent vote could challenge this precedent, putting the future of rent control laws in New York at risk.

As the city awaits the legal outcomes and further measures from the RGB, stakeholders remain divided over the policy’s implications for tenants, landlords, and the wider housing market.
