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.
