- About 57,000 rent-stabilized apartments were reported vacant in 2025, equal to roughly 5.6% of New York City’s approximately 1 million stabilized units.
- The vacancy rate has increased from 3.7% in 2016, although it briefly reached about 7% during the pandemic in 2021.
- Rising taxes, insurance, construction and operating costs are creating tougher economics for owners of older rent-stabilized properties, particularly in the outer boroughs.
What is happening with NYC’s rent-stabilized apartments?
We are looking at an unusual situation in New York City. The city continues to face a severe housing shortage, yet tens of thousands of rent-stabilized apartments are being reported as vacant. Rent-stabilized apartments are homes with legally regulated rents and limits on how much landlords can increase them.
According to landlord filings obtained through a Freedom of Information Law request, approximately 57,000 stabilized apartments were vacant last year. That represents about 5.6% of the city’s roughly 1 million rent-stabilized units.
The rate was 3.7% in 2016 and climbed to around 7% in 2021 when the pandemic disrupted residential demand across the five boroughs.
The latest number does not automatically mean that 57,000 apartments are sitting unused and ready for immediate occupancy. The filings do not identify the reason for each vacancy. Some units may be undergoing renovations, waiting for a new tenant, caught in legal proceedings or part of recently completed buildings that have not yet been fully leased.
What positive developments can we see?
1. Is NYC’s rent-stabilized vacancy rate below its pandemic peak?
Yes.
The reported vacancy rate fell from approximately 7% in 2021 to 5.6% last year. That suggests residential conditions have improved significantly since the height of the pandemic.
Manhattan has also largely returned to pre-pandemic vacancy levels, showing that demand has recovered strongly in one of the city’s most expensive and economically important markets.
2. Does the data show continued demand for NYC housing?
Yes.
A 5.6% vacancy rate means roughly 94.4% of the city’s stabilized units were not reported vacant.
For commercial real estate, that is important context. New York continues to have a massive underlying housing demand base, even as individual properties face operational and regulatory challenges.
3. Could vacant apartments represent future housing supply?
Potentially.
If some vacant units are being held during renovations, legal proceedings or tenant transitions, bringing them back online could add meaningful housing supply without requiring entirely new construction.
For owners and investors, the key question is not simply how many units are vacant. It is how quickly those units can realistically return to the market and what it will cost.
4. Could this create opportunities for investors?
Yes, but selectively.
Older properties with rent-stabilized units may attract investors who understand regulatory requirements, renovation economics and operating costs.
The opportunity may be particularly relevant for buyers who can identify buildings where vacant units can be legally and economically returned to service.
The numbers need to work at the property level rather than simply at the neighborhood level.
5. Does NYC still have strong long-term residential fundamentals?
The broader demand picture remains strong.
New York continues to have a large population, major employment centers, extensive transportation infrastructure and limited developable land.
For commercial real estate investors, these fundamentals can continue supporting multifamily demand even when individual buildings face pressure from regulation and operating expenses.
What challenges are landlords and investors facing?
1. Why are owners struggling to return some apartments to service?
Costs are a major factor.
Older outer-borough properties can face rising insurance premiums, property taxes, maintenance expenses and construction costs while regulated rents remain significantly below market levels.
That creates a difficult equation.
If the cost of renovating a vacant apartment is high but the potential rent increase is limited, the investment may take longer to recover.
2. How has the 2019 Housing Stability and Tenant Protection Act affected the economics?
The law significantly reduced owners’ ability to increase rents following vacancies and limited how renovation costs can be recovered.
For owners of aging buildings, that can make major capital improvements harder to justify.
From an investment perspective, the issue is simple. Higher costs combined with restricted revenue growth can reduce net operating income and property value.
3. Could the rent freeze make the situation more difficult?
It could.
The Rent Guidelines Board recently approved a two-year rent freeze for stabilized apartments.
For tenants, a rent freeze can provide greater affordability and predictability.
For owners, however, it means rental revenue may remain flat while expenses continue increasing.
That gap is especially important in older buildings where maintenance and capital improvement requirements can be substantial.
4. Are all 57,000 vacant apartments actually available?
No.
This is one of the most important qualifications in the data.
Landlords report vacant units each April, but the filings do not explain whether an apartment is being renovated, waiting for a tenant, tied up in Housing Court or simply being held off the market.
The state has also noted that vacant registrations can include newly completed buildings that have not yet been fully leased.
That means we should not treat the 5.6% figure as a direct measure of apartments that could immediately house new tenants.
5. Could Housing Court delays be contributing?
Potentially.
The pandemic created a significant backlog of Housing Court cases, and unresolved cases can affect how quickly landlords regain control of apartments and prepare them for new occupancy.
For owners, every additional month can affect cash flow.
For investors, this makes legal and operational due diligence increasingly important when evaluating multifamily properties.
What does this mean for NYC commercial real estate?
We see the 57,000 vacant-unit figure as both a warning and an opportunity.
The warning is that housing demand alone does not guarantee that every apartment will remain economically viable for its owner. A building can be located in a strong market and still face declining returns when operating expenses rise faster than permitted rental income.
The opportunity is that some vacant apartments may represent underutilized assets that can eventually return to the market.
For commercial real estate investors, owners and brokers, we believe the focus should be on the numbers.
Look beyond the headline vacancy rate.
Analyze the building’s rent roll, stabilized and market rents, property taxes, insurance, maintenance, capital expenditures, renovation costs, legal status and potential timeline for bringing vacant units back online.
A 57,000-unit vacancy figure sounds enormous. But the real commercial real estate story is at the property level.
The question is not simply how many apartments are vacant.
The question is why they are vacant, what it will cost to bring them back, what revenue they can generate and whether the economics justify the investment. For NYC commercial real estate, those calculations will increasingly determine which multifamily assets create value and which ones remain under pressure.
