Housing Platform

The rent freeze that defined the campaign — what was promised, what the independent board did, and where it stands.

The campaign promise

Housing was the center of Mamdani’s 2025 platform, rooted in his years as a foreclosure-prevention counselor in Queens. The headline pledge: freeze rents on the city’s roughly one million rent-stabilized apartments. Around it sat tenant-protection enforcement and, later, an ambitious construction agenda.

The rent freeze — and who actually froze the rents

On June 25, 2026, the city’s independent Rent Guidelines Board voted 7–1 to freeze rents on one- and two-year rent-stabilized leases for October 2026 through September 2027, covering about a million apartments and two million New Yorkers. Mamdani celebrated: “This is the relief that working people across our city deserve.”

The framing matters: the Rent Guidelines Board is an independent nine-member body (two tenant seats, two owner seats, five public members), not a mayoral department. The freeze was its vote, fulfilling Mamdani’s campaign pledge — not the mayor setting rents by decree. Reporting on the vote noted it was the first freeze since the de Blasio era.

The lawsuit

In July 2026, a landlord group — represented by former first deputy mayor Randy Mastro — sued to block the freeze, alleging the board’s process was a “sham.” A judge declined to rule before the October 1 start date; a decision was expected by the end of 2026. As of the September 24, 2026 reporting date, the freeze was scheduled to take effect October 1 with the litigation unresolved. (The City Reporter, September 24, 2026.)

Building: Block by Block

Alongside the freeze, 2026 reporting described a “Block by Block” construction initiative — a plan for 200,000 new homes on public land, tied to a rezoning of East Harlem. The detail comes from Wikipedia’s tracking of 2026 events (accessed September 26, 2026) and should be confirmed against primary city reporting as the plan develops.

Status as of September 2026

Dating honesty. Housing policy moves through boards, courts, and budgets. Every status above carries its reporting date; nothing is asserted beyond it.
