Mamdani Announces Plan To Address NYC’s Housing Crisis ‘Block by Block’

Mayor Zohran Mamdani announced a sweeping plan to confront New York City’s housing crisis “block by block” on Tuesday, setting a goal of building 200,000 new affordable homes and preserving or stabilizing another 200,000 existing homes over the next decade.

“Block by Block: The Housing Plan for a New Era,” detailed in a 112-page report and backed by more than $22 billion in funding over five years in Mamdani’s first executive budget, represents the most ambitious housing agenda of his young administration—and one of the most expansive City Hall has put forward in recent history.

“This plan meets the housing crisis with the urgency it demands,” Mamdani said in a statement. “We are setting the most ambitious housing production and preservation targets in the city’s modern history—and backing them up with investments to match—while also protecting tenants and homeowners, investing in public housing, and ensuring the workers building that housing have good-paying, safe jobs.”

The press conference announcing the plan carried the mood of a victory lap, with officials and supporters gathering the morning after the Knicks clinched their first Eastern Conference finals berth since 1999.

But behind the celebration is a harder test: whether City Hall can turn its expansive promises into homes New Yorkers can actually afford. The report cites a 1.4% rental vacancy rate, the lowest in a half-century, and says 100,000 New Yorkers sleep in shelters on an average night.

Mamdani framed the plan as an attempt to move past the long-running fight over whether the city should focus on building more housing or protecting the people already struggling to stay housed.

“We must fight for both the tenants of today and the tenants of tomorrow,” the mayor said. “Block by Block shows how New York City can do exactly that.”

Build and preserve

The plan’s production goal would start with a near-term ramp-up at the Department of Housing Preservation and Development.

Under the first executive budget, HPD would receive more than $2.5 billion in additional capital funds for new affordable housing construction in fiscal years 2027 and 2028, bringing total funding for those two years to nearly $5 billion. The administration says that would allow HPD to finance about 8,000 subsidized affordable homes per year, a more than 35% increase from FY24 and FY25.

The plan also attempts to push more of those homes toward New Yorkers with the greatest need. Half of the newly financed units would be reserved for the lowest-income households, including 30% for extremely low-income New Yorkers and 20% for very low-income New Yorkers. 

For extremely low-income households moving into new HPD-financed homes without rental assistance, rent would be capped at 25% of monthly income, rather than the 30% standard commonly used in affordable housing.

These subsidies will build on additional reforms—including zoning changes, faster approvals, transit-oriented development, and the use of city-owned land—to unlock more housing.

The announcement also detailed a preservation side of the plan, aimed at one of the city’s harder housing problems: aging rent-stabilized and affordable buildings where rising operating costs, repair needs, and legal rent limits can make it difficult for owners to bring vacant units back online. To keep these existing units from slipping into distress or disappearing altogether, the city plans to put more than $2 billion toward HPD preservation programs in FY27 and FY28.

Mamdani tied his housing push to labor standards, announcing that targeted city-assisted housing projects covered by the Construction Justice Act would carry a combined wage and benefits minimum of $40 per hour.

What this means for current tenants

For tenants already living with unsafe conditions or rising pressure from landlords, Mamdani promised a more aggressive enforcement posture from City Hall.

The centerpiece is a new “Fix the City” campaign aimed at the landlords with long-standing and egregious violations.

Under the program, HPD would target the most troubled housing portfolios with roof-to-cellar inspections, emergency repairs, and anti-harassment enforcement. In the most serious cases, the city could seek to remove negligent owners or managers and transfer distressed buildings to responsible preservation owners.

Tenant advocates cast that as one of the plan’s most immediate promises.

“The city is finally going to step up in its code enforcement to hold landlords accountable for the conditions in our homes,” said Sumathy Kumar, a tenant advocate who spoke at the announcement. 

She added that the plan would make it easier for tenants to use city tools, “from allowing us to reschedule code inspections to expanding the kinds of violations that justify rent strikes, to making sure every heat complaint gets the attention it deserves.”

Mamdani said those changes were shaped by the city’s Rental Ripoff Hearings, where tenants described myriad problems that were shaping their daily lives.

“When you sit across the table from a tenant who shows you a video of a mother with a young child who's disabled, and how that mother has to carry that child in her bare hands every day from the school bus up the steps of the apartment building, because that elevator is broken,” he said, “you leave that room with an understanding of just how quickly this city needs to move.”

What this means for landlords

For building owners, the plan offers both relief and a warning.

The administration acknowledges that many affordable, rent-stabilized buildings are being squeezed by rising operating costs, especially insurance. To ease that pressure, the city cited its previously announced plan to launch a $100 million city-backed insurance program for regulated housing.

The city also cited additional preservation tools for affordable housing owners, including more flexible reserve rules, faster access to certain property tax exemptions, and pre-development support for nonprofit owners and HDFC cooperatives trying to qualify for long-term city financing.

During a press Q&A, Mamdani pushed back on a Wall Street Journal report suggesting that the plan would exempt some landlords from his likely rent freeze. He said that characterization was inaccurate, and clarified that the referenced policy is a long-standing HPD tool used in limited cases when regulated affordable buildings are in financial distress. 

In some of these cases, HPD can allow the rent on a vacant unit to return to the rent allowed under the building’s regulatory agreement, often while using Section 8 vouchers so that tenants do not pay more out of pocket.

Mamdani said it would not exempt landlords from Rent Guidelines Board limits, and Deputy Mayor Leila Bozorg added that the tool would be used case by case, often with nonprofit owners, and that tenants would not pay more as a result.
