The New York City Rent Guidelines Board approved Mayor Zohran Mamdani’s key campaign promise to “freeze the rent” on Thursday — in a move landlord advocates slammed as “an absolute farce.” The board passed a rent freeze on both one-year and two-year leases for the Big Apple’s roughly 1 million rent-stabilized units in a 7-1 vote. Arpit Gupta, an appointee of Mamdani’s predecessor Eric Adams, was the one no vote.
