Rent stabilization is a New York City housing policy that limits how much a landlord can increase your rent each year and gives you the right to renew your lease. If your apartment is rent stabilized, your rent increases are capped at rates set annually by the NYC Rent Guidelines Board — and your landlord cannot simply refuse to renew your lease or evict you without cause.
Roughly one million NYC apartments are rent stabilized, but tenants often don’t know their apartment qualifies — or discover it only after years of overpaying. This guide walks you through exactly how to find out.
What Is Rent Stabilization?
Rent stabilization applies primarily to apartments in buildings with six or more units built before 1974, where the rent was below a certain threshold when the law was enacted. The 2019 Housing Stability and Tenant Protection Act significantly strengthened tenant protections and made it harder for landlords to remove apartments from stabilization.
Under rent stabilization, your landlord must:
- Renew your lease each year (with limited exceptions)
- Follow annual rent increase guidelines set by the NYC Rent Guidelines Board
- Provide you with a copy of the apartment’s rent history if you request it
- Register the apartment with the New York State Division of Housing and Community Renewal (DHCR)
How to Check If Your Apartment Is Rent Stabilized
Method 1: Check Your Lease
The fastest first step is to read your lease carefully. Rent-stabilized leases are required to include a Rent Stabilization Lease Rider — a document that describes your rights under the Rent Stabilization Law. If your lease includes this rider, your apartment is stabilized.
Look for language referencing “Rent Stabilization Code,” the “NYC Rent Guidelines Board,” or a section labeled “Rider to Lease.” If you’re unsure what you’re reading, the NYC Rent Guidelines Board publishes plain-language guides at rentguidelinesboard.cityofnewyork.us.
Method 2: Look Up Your Building on the NYC Rent Stabilized Buildings Database
The NYC Department of Finance publishes an annual list of rent-stabilized buildings through its Automated City Register Information System (ACRIS). But the most user-friendly tool is the NYS DHCR Rent Stabilized Building Search.
Go to apps.hcr.ny.gov/BuildingSearch/ and enter your building’s address. The tool will show whether your building is registered as containing rent-stabilized apartments. Note: it shows building registration, not individual unit status — your specific unit may or may not be stabilized even if the building is listed.
Method 3: Request Your Apartment’s Rent History from DHCR
This is the most definitive method. Under New York law, you have the right to request the complete rent history for your apartment from the New York State Division of Housing and Community Renewal (DHCR). The rent history shows every registered rent going back years and will make clear whether your apartment has been registered as stabilized.
To request your rent history:
- Go to apps.hcr.ny.gov/RentHistory/
- Enter your building address
- Select your apartment number
- Submit the request — it’s free and processed online
DHCR will mail you the rent history, typically within a few weeks. If your landlord has been overcharging you, the rent history is the document you’ll need to file a complaint.
Method 4: Use JustFix’s Who Owns What Tool
Who Owns What, a free tool from tenant advocacy organization JustFix, lets you look up a building’s ownership history, landlord connections, and rent-stabilized unit count. It pulls from public NYC data and can quickly tell you how many stabilized units a building has. If your building shows stabilized units and you’re not getting stabilization protections, that’s a red flag worth investigating.
What If Your Building Is Stabilized But Your Landlord Claims It Isn’t?
This is more common than you might think. Some landlords — whether through error or intentional deception — fail to register units with DHCR, skip the stabilization rider in leases, or charge market-rate rents on units that should be stabilized. This is called rent overcharge, and it’s illegal.
If your rent history shows the apartment was stabilized but your landlord has been charging higher rents without authorization, you can file a rent overcharge complaint with DHCR. If found liable, your landlord may owe you the overcharged amounts — potentially going back years — plus interest and possibly treble damages if the overcharge was willful.
File a complaint at apps.hcr.ny.gov/webdcs/ or by calling DHCR at (718) 739-6400.
What Protections Does Rent Stabilization Give You?
If your apartment is rent stabilized, here’s what you’re entitled to:
- Limited rent increases: Rent can only go up by the percentage the NYC Rent Guidelines Board approves each year for one- or two-year lease renewals.
- Right to lease renewal: Your landlord must offer you a renewal lease, with very limited exceptions (like owner occupancy or demolition).
- Protection from illegal eviction: Your landlord cannot evict you without cause, and must follow specific legal procedures.
- Right to sublease: In most cases, you have the right to sublet your apartment with landlord consent (which cannot be unreasonably withheld).
- Succession rights: Family members who live with you may have the right to take over your lease if you move out or die.
When Can an Apartment Lose Rent Stabilization?
Since the 2019 Housing Stability and Tenant Protection Act, it is much harder for apartments to leave stabilization. The two prior pathways — high-rent vacancy deregulation and high-income deregulation — were both eliminated. Today, apartments can leave stabilization only in limited circumstances, such as:
- The building leaves a tax incentive program like 421-a (when the benefit expires)
- The building is converted to cooperative or condominium ownership under specific conditions
- An owner occupancy exception applies (rare and legally complex)
If your landlord tells you your apartment is no longer stabilized, get the specific legal reason in writing and consult a tenant attorney before accepting that claim.

Frequently Asked Questions
How do I know if my apartment is rent stabilized if I just moved in?
Check your lease for a Rent Stabilization Rider. Then look up your building at apps.hcr.ny.gov/BuildingSearch/ and request your unit’s rent history from DHCR. These three steps together give you a complete picture.
My building was built after 1974. Can my apartment still be stabilized?
Yes, in some cases. Buildings that received certain NYC tax incentives (like 421-a or J-51 benefits) are required to have rent-stabilized apartments for the duration of those benefits, regardless of when they were built. Check DHCR’s database to be sure.
My landlord raised my rent more than the guideline. What can I do?
File a rent overcharge complaint with DHCR at apps.hcr.ny.gov/webdcs/ or call (718) 739-6400. Gather your lease, any rent receipts, and your rent history document before filing. You may also want to contact a tenant attorney or legal aid organization.
Does rent stabilization apply in all five NYC boroughs?
Yes. Rent stabilization applies citywide — in all five boroughs — as well as in Nassau, Rockland, and Westchester counties. The same DHCR rules and rights apply regardless of borough.
Can my landlord refuse to renew my lease if my apartment is stabilized?
Almost never. Under rent stabilization, your landlord must offer a renewal lease. The narrow exceptions — primarily owner occupancy, withdrawal from the rental market, or demolition — require formal legal processes and DHCR approval in most cases. If your landlord refuses renewal without a valid legal reason, contact DHCR immediately.
What is the difference between rent stabilization and rent control?
Rent control applies only to a small number of apartments in buildings built before 1947 where the same tenant (or their successor) has lived continuously. Rent control typically has even stricter limits on increases. Rent stabilization is far more common and applies to roughly one million NYC apartments. Both are overseen by DHCR.
