Mayor Zohran Mamdani’s appointees to the New York City Rent Guidelines Board delivered a 7-1 vote in late June 2026 approving zero rent increases on one- and two-year leases for roughly one million rent-stabilized apartments. The policy takes effect October 1, 2026, and runs through September 30, 2027, directly implementing a central campaign pledge on housing affordability. Landlords have filed lawsuits alleging improper influence over the board process, creating residual uncertainty around implementation. Traders have incorporated this confirmed board action, alongside the administration’s control over the relevant regulatory body, into the current 79.7% implied probability for a freeze before 2027, while pricing in risks from litigation or potential delays.
