The rent freeze
Mamdani campaigned on a guarantee to freeze rents for the city's roughly 1 million rent-stabilized apartments, home to about 2.4 million tenants, after four straight years of increases under Adams totaling about 12% on one-year leases. The Rent Guidelines Board he appointed delivered the first freeze covering both one- and two-year leases in the board's history on June 25, 2026. Landlord groups say the vote ignored the board's own cost data and are weighing lawsuits, though none had been filed as of early July 2026.

Landlords outside Manhattan told The City Reporter that the rent freeze and the 2019 tenant-protection law made costly repairs financially impossible to recoup, pointing to the vacancy numbers as evidence the laws were hollowing out the stabilized housing stock.
