Mayor Zohran Mamdani unveiled his solution to New York City’s housing crisis, a nod to his signature campaign promise to boost Gotham’s housing supply.“Block by Block: The Housing Plan for a New Era” calls for a five-year, $22 billion capital investment to build 200,000 new “affordable” units, preserve another 200,000, and repair city public housing over the next decade. It’s a modest revision of his original $100 billion commitment on the campaign trail.The self-proclaimed Democratic socialist prefaced his announcement with an invocation of Austin, Texas, where the inflation-adjusted rent average fell 19% from 2021 to 2025 despite a population boom. Economists surely gleamed at Mamdani’s free market flattery.

But Mamdani’s homage to Austin ends there. New Yorkers, whose median rents are soaring to all-time highs, must be dismayed by Block by Block’s fine print.

New York City’s newly built units will be rent-stabilized. It’s true that Austin offered density bonus programs, awarding additional square footage to developments that included income-restricted units. The difference? Austin treated those units as an incentive for more free-market activity. Mamdani’s plan, by contrast, presents rent-stabilized apartments as the city’s chief housing solution.
