- Political Maneuvering: mayor mamdani introduced a limited rent increase policy as a performative gesture rather than a structural solution to the city's housing shortage.
- Limited Scope: the program targets a negligible fraction of the city's fifty thousand vacant rent-stabilized units, leaving the vast majority of uninhabitable apartments untouched.
- Regulatory Constraints: current state law restricts allowable renovation cost recoupment to levels far below the actual capital investment required to restore distressed units.
- Capital Inefficiency: systemic rent caps combined with high rehabilitation costs render private ownership of older buildings economically unviable, incentivizing long-term vacancy.
- Administrative Discretion: the policy shifts power to the mayoral housing agency, allowing officials to exercise case-by-case control over property owners instead of implementing market-wide reforms.
- Subsidy Reliance: the proposal lacks a clear path for legal rent increases, necessitating potential reliance on existing federal or state subsidy mechanisms rather than market adjustments.
- Perverse Incentives: rent freezes and discretionary control may intensify owner distress, encouraging the further withdrawal of housing supply from the market.
- Ideological Obstruction: the administration avoids necessary revisions to the housing stability and tenant protection act to satisfy political allies, prioritizing optics over housing availability.
On Tuesday, New York City Mayor Zohran Mamdani announced that owners of vacant regulated apartments would be eligible for a “one-time” rent increase if their units are part of city-financed, city-regulated affordable housing. The announcement was billed as relief for distressed rent-stabilized landlords whose vacant units can’t be economically repaired at current rents.
In reality, the measure is something closer to a political maneuver. It will affect a minuscule share of the city’s long-term vacant apartments, counterproductively create incentives to keep more units off the market, and place owners at the mercy of a mayoral housing agency. The real culprit behind the city’s vacancy crisis is a 2019 state law that created it in the first place—and that Mamdani has no intention of fixing.
Of the city’s roughly 1 million rent-stabilized apartments, an estimated 50,000 units sit vacant because their rents cannot be raised enough to justify costly renovations. (Precise figures aren’t available because the state’s Division of Housing and Community Renewal, which oversees rent stabilization, does not release the data—even though it collects it.) Readers may wonder: How is it possible that there are any vacancies in a city with a severe housing shortage?
To answer that, go back to 2019, when Albany passed the Housing Stability and Tenant Protection Act (HSTPA). Before HSTPA, when a tenant moved out, rent-stabilized landlords were allowed a “vacancy bonus”—a larger rent increase—to compensate for years of below-market raises. Once a unit’s legal rent reached $2,774.76, it could be entirely deregulated upon vacancy.
Tenant activists argued that arrangement created an incentive for landlords to harass tenants into leaving in order to capture the bonus. In response to these allegations, the 2019 law severely restricted owners’ ability to raise rents.
Today, landlords can no longer increase rents between tenancies. And when an apartment requires renovation, they can recoup at most up to $50,000 over 12 years—a maximum monthly rent increase of $347.
Rehabbing an apartment in New York City frequently costs double that or more. According to a 2018 analysis by the city’s Independent Budget Office, bringing highly distressed public-housing buildings in Brooklyn into good repair would cost an average of $260,000 per unit—roughly $325,000 in today’s dollars. Similar math constrains private owners. As a result, tens of thousands of apartments are uninhabitable and economically unviable to renovate.
How does Mamdani’s plan change this equation? By the administration’s description in Tuesday’s press conference, it seems like a longstanding HPD program would expand to a broader set of distressed properties. The mayor’s proposal would allow buildings subject to HPD financing and regulatory agreements to receive a rent bonus on vacant apartments on a case-by-case basis.
It remains unclear how city regulatory agreements can supersede the HSTPA’s restrictions on rent increases. Deputy Mayor Leila Bozorg suggested that federal Section 8 housing vouchers might be used to cover the higher rent.
Another answer may lie in Section 610 of the Private Housing Finance Law, signed by Governor Kathy Hochul in December 2022. Similar to Section 8, it allows owners of affordable housing projects with rental assistance to collect the full subsidy amount even if it exceeds the legal stabilized rent, without affecting what tenants pay out of pocket. While the law requires owners to execute an amendment to their existing regulatory agreement, Section 610 is explicitly a subsidy mechanism, not an authority to raise rents above HSTPA’s limits.
Whatever the mechanism, the Wall Street Journal reports that City Hall “projects that hundreds of apartments could use the rent increase”—a drop in the vacancy bucket. The proposal would do nothing to address the vacancies that are in buildings not subject to HPD financing or regulatory agreements, which make up the vast majority of the city’s 50,000 apartment vacancies. The mayor hasn’t called for overhauling the HSTPA to allow for vacancy bonuses, which would solve the problem for all owners as-of-right, without needing a discretionary review by a city housing authority.
But case-by-case control is politically useful for a mayor who built a campaign on the premise that landlords of rent-stabilized units were profiting too much. It lets him claim credit for returning vacant apartments to use while avoiding any concession that the HSTPA itself is broken. Such a solution will also give reason for far-left housing advocates to push for more public intervention in the housing market.
What’s more, in Tuesday’s press conference, Mamdani said that no tenant would see rents rise beyond what the Rent Guidelines Board determines, even if their apartment is otherwise eligible for a reset under the new program. Current tenants in affected buildings would remain subject to whatever the Rent Guidelines Board sets—including a freeze, if one is enacted in June.
A rent freeze, however, would only accelerate distress in stabilized buildings and force more units into vacancy. Owners might remove units from the market in the hopes of obtaining a vacancy bonus, potentially restricting supply further. Mamdani’s program thus provides an illusion that something is being done to address vacancies, which allows him to delay the reality that stabilized tenants will eventually need to pay more to keep their buildings afloat.
If the mayor were serious about filling vacancies, he would provide political cover for his leftist allies in Albany to amend the HSTPA and allow re-introduced vacancy bonuses. Instead, his program is a fig leaf—a chance to claim credit for “solving” a minuscule slice of a crisis that will only deepen if he achieves his campaign’s rent freeze.
