About one million apartments in New York City are subject to rent stabilization. Among rental units in NYC, this is roughly half.
Many tenants don't know whether their apartment is one of them. Some learn after years of paying market-rate rent that they were actually entitled to stabilized rent the whole time. Others discover their stabilized status only when they try to enforce a tenant right that doesn't exist in market-rate apartments — such as the right to lease renewal at a regulated rate.
If you're not certain whether your apartment is rent stabilized, the verification process is straightforward and free. Here's how to do it.

Step 1: Check the building's apparent characteristics
Some characteristics make rent stabilization more or less likely. None of them are conclusive — verification through official sources is the only definitive answer — but they help orient you.
Rent stabilization is more likely if:
— The building has six or more residential units. — The building was built before 1974. — The building has received any form of tax abatement (J-51, 421-a, 421-g, and others) during the tenancy. — Prior tenants you can identify report being rent stabilized.
Rent stabilization is less likely if:
— The building has fewer than six units (most are exempt). — The building was built after 1974 without tax abatements (most are exempt unless there's a specific qualifying program). — The building is a condominium or cooperative (individual unit purchases generally do not preserve stabilization, though there are exceptions). — The rent is above the current statutory deregulation threshold (a path that was largely closed by HSTPA 2019, but historical deregulations may still apply).
These signals are starting points, not conclusions.
A note on condos, co-ops, and tax-abated buildings
NYC housing law is unusually complex around certain building types. Several common situations produce surprising results:
Condos and co-ops with active tax abatements. Some condominium and cooperative units remain stabilized because of tax abatement programs or prior regulatory status. Buildings that converted from rental to condo or co-op may have retained stabilized status for tenants who lived there before conversion. Buildings receiving J-51 or 421-a benefits may have stabilized rental units even within an otherwise condo or co-op structure.
Converted lofts. Some loft buildings, particularly in Brooklyn and Manhattan industrial areas, fall under the Loft Law (Article 7-C of the Multiple Dwelling Law). Loft Law units have rent stabilization protections that operate alongside the standard Rent Stabilization Law.
Sponsor units in co-op buildings. When a rental building converts to a co-op, units owned by the original sponsor that continue to be rented out may retain stabilized status for tenants who lived there before conversion or for certain successor tenants.
421-a and 421-g buildings. These tax abatement programs typically require participating buildings to subject all rental units to rent stabilization for the duration of the abatement. Some of those abatements continue for 20 years or more. A 2010 or 2015 building can be entirely stabilized for this reason.
If you live in any of these building types, the standard tests (six-plus units, pre-1974) may not apply. Verification through DHCR is the only reliable way to know your status.
Step 2: Look for the Rent Transparency Act sign
Effective January 1, 2026, New York City's Rent Transparency Act (Intro. 1037) requires landlords of rent stabilized buildings to post a notice in a visible location in the building informing tenants of their stabilized status.
The notice must specify:
- That the building contains rent stabilized units.
- Where tenants can verify their unit's stabilization status (DHCR contact information).
- That tenants have specific rights including rent overcharge claims and limited rent increases.
The sign is typically posted in the lobby, mailroom, or other common area.
If your building has the sign, that is a strong (though not conclusive) signal that some units in the building are stabilized — though it does not guarantee your specific unit is stabilized.
If your building should have the sign but doesn't, that is itself a violation of the law that can be reported.
Step 3: Check your lease
Examine your current lease. Rent-stabilized leases are required to include specific language identifying them as such. The Rent Stabilization Code lease (RTP-8) is the standard form for rent-stabilized renewals.
If your lease is on the RTP-8 form or includes language stating it is subject to the Rent Stabilization Law, your unit is rent stabilized.
If your lease is a generic market-rate form (often a NY Board of Real Estate "Standard Form Lease" or similar), the apartment may or may not be stabilized. The lease being market-rate does not by itself prove the apartment is market-rate — landlords sometimes provide market-rate leases for units that should legally be on a stabilized lease.
Step 4: Request your rent history from DHCR
This is the definitive verification step. (Full guide: how to request and read your NYC rent history.)
The New York State Division of Housing and Community Renewal (DHCR) maintains a Building Registration database for all rent-stabilized buildings. The database includes the registration history for each apartment.
To request your rent history:
Visit the DHCR website at hcr.ny.gov.
Look for the "Ask HCR" web portal or the rent history request form.
Submit the request, providing your name, the apartment address (including apartment number), and the dates you have lived there.
Alternatively, call 833-499-0343 (the Rental Information Hotline) or email [email protected].
DHCR will provide the registration history for your unit. The records typically show:
- Whether the apartment is registered as rent-stabilized.
- The legal regulated rent for each year covered by the registration.
- Any registered changes (vacancy decontrol claims, MCI/IAI rent adjustments, etc.).
The request is free. Response time varies but typically ranges from a few weeks to a few months.
Step 5: Interpret the rent history
If the rent history shows your apartment registered as rent-stabilized with a legal regulated rent: you are in a rent-stabilized apartment.
If the rent history shows your apartment registered as previously stabilized but currently deregulated: the apartment was once stabilized but no longer is. Many such deregulations occurred before HSTPA 2019, when high-rent vacancy decontrol was still permitted. After HSTPA 2019, deregulations are much harder. The validity of pre-2019 deregulations is sometimes contested.
If the rent history shows no registration record at all: the apartment may genuinely not be rent stabilized, OR the landlord may have failed to register a stabilized apartment. Either possibility requires further investigation.
If you believe your apartment should be stabilized but the records say otherwise, contact a tenant legal services organization. The specific facts will determine the right next step.
Step 6: If you are stabilized — what your rights include
If verification confirms you are in a rent-stabilized apartment, several specific rights apply.
Limited rent increases. Annual increases are capped by the Rent Guidelines Board (RGB) vote. For the 2025-2026 lease cycle (October 1, 2025 through September 30, 2026), the cap is 3 percent for one-year renewals and 4.5 percent for two-year renewals. The 2026-2027 cycle increases will be voted on in late June 2026.
Right to lease renewal. The landlord is required to offer renewal at one of the RGB-authorized rates. Refusal to renew is permitted only for specific reasons defined in the Rent Stabilization Code.
Right to remain. The landlord cannot evict for "no cause" — meaning, in the absence of a specific lawful reason such as nonpayment, breach of lease, or owner occupancy.
Right to rent overcharge claims. If you have been paying more than the legal regulated rent, you may be entitled to refund of the excess plus interest, and potentially treble damages. Claims have specific time limits — generally four years for overcharge claims — so timing matters.
Right to MCI/IAI scrutiny. Major Capital Improvement and Individual Apartment Improvement rent adjustments must follow specific rules. Improperly applied MCI/IAI increases can be challenged through DHCR.
Right to succession. Family members who reside in a stabilized apartment for a qualifying period may have succession rights when the named tenant moves out, dies, or transfers the unit.
Right to a roommate — with a rent cap. Under the Roommate Law you can share your apartment, but in a stabilized unit you cannot charge a roommate more than their proportional share of the legal rent — a limit many tenants don't know they're bound by.
Step 7: If you are stabilized but were charged market-rate — what to do
If your rent history shows your apartment is rent stabilized but you have been charged market-rate rent, you may have a rent overcharge claim.
File a complaint with DHCR. The Rent Overcharge complaint form is available at hcr.ny.gov. The complaint must include the rent history, your lease(s), and documentation of rent paid.
Contact a tenant legal services organization. Overcharge claims are technical and the calculation of damages depends on specific facts. Legal Aid Society, Legal Services NYC, Met Council on Housing, and tenant-side housing attorneys all handle these cases.
Note the time limits. Overcharge claims generally must be filed within four years of the overcharge. Older overcharges may be barred. The calculation method also depends on the timing of the overcharge.
Note the potential damages. Successful overcharge claims may result in refund of overcharges plus interest. In cases of willful violation, treble damages (three times the overcharge) may apply. The financial stakes can be significant.
Step 8: If you are not stabilized — what your rights include
If verification confirms your apartment is not rent stabilized, you are in a market-rate apartment. Different protections apply.
You have rights under:
— Good Cause eviction law (2024). Provides certain protections for tenants in qualifying market-rate apartments, including required notice for lease non-renewal and protection against arbitrary eviction. Coverage depends on building characteristics and rent thresholds.
— HSTPA 2019 rent increase notice rule. Requires 30/60/90 days advance written notice for rent increases of 5 percent or more.
— Federal Fair Housing Act and NYC Human Rights Law. Protections against discrimination based on race, national origin, source of income (including Section 8), family status, disability, and other protected categories.
— Security deposit law (GOL §§ 7-107, 7-108). Same one-month cap and 14-day return rule as stabilized tenants.
Market-rate tenants do not have the right to lease renewal at a regulated rate. Their rent increases are limited by the 5 percent notice rule but not by the RGB's percentage caps.

Frequently Asked Questions
How do I know for sure if my apartment is rent-stabilized? The definitive way is to request your apartment's rent history from New York State's Division of Housing and Community Renewal (DHCR) at hcr.ny.gov — it's free, and it's the actual proof. Use the "Ask HCR" web portal or the rent history request form, or call the Rental Information Hotline at 833-499-0343 or email [email protected]. DHCR returns your unit's registration history, showing whether the apartment is registered as rent-stabilized and the legal regulated rent for each year. Signals like a pre-1974 building with six or more units, or a 421-a or J-51 tax abatement, make stabilization more likely and help orient you — but none are conclusive. Only the official rent history settles it, so when in doubt, request the record.
Does my building's age or size matter? Yes — age and size are two of the strongest orienting signals, though never conclusive on their own. A building built before 1974 with six or more residential units is the most common rent-stabilized category, so those two traits together make stabilization likely. Conversely, a building with fewer than six units is usually exempt (most small buildings are), and a building built after 1974 without any tax abatement is usually exempt too, unless a specific qualifying program applies. Treat these as starting points that tell you where to look, not as proof — a building can defy the pattern, which is why the DHCR rent history is the only definitive answer.
Can a new building be rent-stabilized? Yes — a brand-new building can be entirely rent-stabilized because of a tax abatement. Programs like 421-a and 421-g typically require participating buildings to place all rental units under rent stabilization for the full duration of the abatement, and some of those abatements run for 20 years or more. That means a 2010 or 2015 building — even one that looks and rents like luxury housing — can be fully stabilized for as long as the benefit lasts. This is one of the most common surprises, so the usual shortcuts (pre-1974, six or more units) don't apply to tax-abated new construction. Verify through DHCR, since the abatement status is what controls.
What if I've been paying market rent but I'm actually stabilized? It happens more than people expect — some tenants discover after years of paying market-rate rent that their unit was stabilized the whole time, because a landlord can hand you a market-rate lease for an apartment that should legally be stabilized. Your rent history is how you find out: if it shows the apartment registered as rent-stabilized with a legal regulated rent below what you've paid, you were likely overcharged and are entitled to the regulated rent going forward. That discovery is the start of a separate process — a rent overcharge claim, where you may recover the excess plus interest, and treble damages if the violation was willful. Confirm your status first; the rent history is the evidence.
