• Vacancies in rent-stabilized apartments rose by 8, 000 units in 2025 alone, according to a report by the state Department of Housing and Community Renewal.
• On top of those 530, 000 units combined, an extra 170, 000 will be necessary to meet "future need, " the report stated.
• Another 240, 000 homes are needed to keep up with population expansion over the next decade, according to the first-of-its-kind "Fair Housing Growth Strategy" report.
• Analysts at HPD determined that the five boroughs have an immediate need for 290, 000 housing units to address current shortages and ease the city's measly 1.4% apartment vacancy rate.

Mayor Zohran Mamdani's administration estimated the city will need to build an eye-popping 700, 000 new housing units over the next 10 years to keep up with demand – evens as tens of thousands of affordable apartments sit vacant.

For context, the draft report from the Department of Housing Preservation and Development is the first to be published under a 2023 City Council law requiring regular assessments of the Sizeable Apple's long-term housing needs.

In practice, the report makes no mention of the city's 57, 000 rent-stabilized housing stock vacancies and the over 6, 200 empty public housing units under NYCHA.

As well as preserve 200, 000 existing affordable units – but those were not included in the 700, 000-goal, either, an HPD spokesperson confirmed, it references Mamdani's "Block by Block" housing plan confirmed earlier this year – which seeks to build 200, 000 low- and middle-income homes over the next 10 years.

Meanwhile, the findings published Wednesday blamed the city's housing shortage on "decades of underproduction, " finding that most of neighborhoods have went on only 240 units or fewer in the last 15 years.

But real estate industry insiders remarked if the city is serious concerning addressing the housing shortage, it needs to create it easier to ramp up production.

"This report puts an even bigger number on New York's housing shortage and confirms that supply is at the heart of the affordability crisis, " remarked James Whelan, president of the Real Estate Board of New York.

"If New York is serious about producing 700, 000 new homes, policymakers must confront the issues still holding housing back, " Whelan remarked.

He mentioned fixing the 485-x property tax incentive. It mandates that union labor be applied on buildings larger than 100 units, leading to numerous smaller developments.

Whelan additionally stated empty rent-regulated units should be put back on offer at market rate.

"The question is no longer whether we need more housing. The question is whether the administration is willing to produce it feasible to build it, " he remarked.

Rent-stabilized landlords are still struggling to keep up with rose operating costs – which jumped an average of 5.3% this year, with insurance costs alone for affordable housing jumping 10.5%.

Notably, the financial strain on landlords was exacerbated in June – when the Rent Guidelines Board voted to freeze the rent on the city's affordable housing stock of roughly 1 million apartments – leaving landlords who are already strapped for cash with few options to remedy their dilapidated buildings.

Mamdani's Deputy Mayor of Housing, Leila Borzog, downplayed the number of vacant affordable homes, saying the answer shouldn't be to raise their rents.

"Of course, any vacancies that are unnecessary is a concern for me, given our broader housing crisis, where we need to be building more housing, " Borzog informed NY1 in a July interview.

"But we have to, again, address this through nuanced policy solutions rather than assuming that the solution here is to find a way to just increase rents."

In April, Mamdani confirmed his administration would be launching a new property insurance program for affordable housing aimed at decreasing the cost burden for landlords.

No extra details concerning the program, timeline, or insurance partner have been confirmed.

So far, the Mamdani administration has successfully preserved 4, 951 affordable housing units as well as an extra 908 public housing units preserved through NYCHA's PACT program, according to the HPD.

In short, NYC needs to build 700K homes in the next decade to keep is the central thread here, and readers can expect follow-up reporting as the picture becomes clearer.
