New York City Mayor Zohran Mamdani's newly announced multi-year rent freeze is drawing praise from tenant groups and left-wing activists, but critics warn it amounts to an unconstitutional seizure of private property and is likely to be struck down by the U.S. Supreme Court. The freeze denies landlords any rent increases for at least two years, with the mayor promising to extend it as long as he is in office.
Justice Thomas signals readiness to hear challenge
In 2023 and twice in 2024, the Supreme Court declined to hear challenges to New York's rent regulations. However, Justice Clarence Thomas wrote at the time that the constitutionality of the regulations was “an important and pressing question” and that he looked forward to a case clearly demonstrating the government was going too far in taking an owner's property. According to former New York Lieutenant-Governor Betsy McCaughey, writing in the Toronto Sun, Mamdani's rent freeze gives Thomas precisely that case “on a silver platter.”
Rent freeze defies state law and economic reality
Under New York State law, the Rent Guidelines Board (RGB) must determine allowable rent hikes based on specific costs landlords incur. But Mamdani's handpicked RGB members ignored the law, voting for zero increases despite fuel costs rising 11% and insurance costs climbing 10.5% over the past year. RGB member Christina Smyth, appointed by former mayor Eric Adams, resigned in protest hours before the vote, stating the freeze “was decided last year on the campaign trail.” She pledged to assist anyone willing to wage a legal battle against the scheme.
Property confiscation as hidden agenda
McCaughey argues that the rent freeze is deliberately designed to force buildings into disrepair, creating conditions for widespread confiscation. On May 29, Mamdani announced that when landlords fail to keep buildings up to code, “we will take aggressive legal action” to “transfer ownership to responsible stewards that include community land trusts, non-profits and even the tenants themselves.” New York law already allows such transfers under extreme circumstances—applying to fewer than 30 properties in 2024—but the rent freeze would turn many more landlords into targets by depriving them of revenue needed for maintenance.
“Think Bolshevik Moscow in 1917, when the communists annulled private property rights, seized buildings and decreed them communal living spaces,” McCaughey wrote. “Lefties now become the new land barons.”
Legal battle already underway
A lawsuit filed in the U.S. District Court for the Southern District of New York against the city and the RGB challenges the rent freeze, focusing on “zombie” apartments—units that cannot be rented because a 2019 state law caps owner recovery for repairs at $50,000, far below actual costs. The state's Division of Housing and Community Renewal estimates 57,000 such units are vacant and worthless to owners. McCaughey says this case or a new challenge to the freeze could reach the high court in two to three years.
“If the justices slap down Mamdani's rent freeze, the confiscations or any portion of the city's rent regulatory scheme as an unconstitutional 'taking,' as they're likely to do, Mamdani will have to comply, no matter what the throngs of left-wing tenant advocates shout in the streets,” McCaughey wrote.
Broader implications for property owners
McCaughey warns that the rent freeze threatens not just landlords but all property owners in New York. “Everyone who owns anything—a home, a rental property, a diner, a bodega or other business—has a stake in this legal fight. Mamdani's scheme to seize rental properties is a red flag that all property rights are in peril. He's going after landlords first, but you could be next.”
