What Is Rent Stabilization?
Rent stabilization is a NYC law that limits how much landlords can raise rent each year. It applies to about 1 million apartments—roughly 44% of all rental units in the city.
Rent Stabilization vs. Rent Control
These are different programs. Rent control is much rarer (only ~16,000 units) and applies to tenants who have lived in buildings built before 1947 since before 1971.
| Feature | Rent Stabilized | Rent Controlled |
|---|---|---|
| Units in NYC | ~1,000,000 | ~16,000 |
| Building age | Before 1974 | Before 1947 |
| Rent increases | RGB sets annually | MBR formula |
| Succession rights | Yes | Yes |
Which Buildings Are Rent Stabilized?
Generally, a building is rent stabilized if:
- Built before January 1, 1974 AND has 6 or more units
- OR built after 1974 with tax benefits like 421-a or J-51
- OR converted to co-op/condo but tenant remained as renter
Important: Before 2019, apartments could be deregulated when rent exceeded $2,774/month and the tenant moved out. The 2019 Housing Stability and Tenant Protection Act (HSTPA) eliminated this. Now, once stabilized, always stabilized.
How to Check If Your Apartment Is Rent Stabilized
Method 1: Request Your Rent History from DHCR (Most Reliable)
The Division of Housing and Community Renewal (DHCR) maintains records of all rent stabilized apartments. You can request your apartment's rent history for free.
How to request:
- Go to
hcr.ny.gov - Search for "Request for Rent History"
- Fill out the form with your address and apartment number
- Mail, fax, or submit online
- Wait 2-4 weeks for response
The rent history will show every registered rent since 1984, any legal rent increases, and whether the apartment is currently registered as stabilized.
Method 2: Check Your Lease
Rent stabilized leases must include specific language and a rent stabilization rider. Look for:
- "This apartment is subject to the Rent Stabilization Law"
- A separate rent stabilization rider (additional pages)
- Information about the Rent Guidelines Board
Warning: Some landlords illegally omit this language. If your building qualifies but your lease doesn't mention stabilization, the apartment may still be stabilized.
Method 3: Check Building Registration
You can look up if a building is registered as rent stabilized:

- NYC Open Data: Search "rent stabilization" datasets
- DHCR Building Search: Check registration status
- DOF Property Records: Shows tax abatement status (421-a, J-51)
What Rent Stabilization Means for You
Rent Increase Limits
The Rent Guidelines Board (RGB) sets maximum rent increases each year. For 2025-2026:
- 1-year lease: 2.75% increase
- 2-year lease: 5.25% increase
Your landlord cannot charge more than this unless they've made major capital improvements (MCIs) or individual apartment improvements (IAIs)—and even those are now capped.
Lease Renewal Rights
Landlords must offer you a lease renewal 90-150 days before your lease expires. They can only refuse renewal for specific legal reasons (non-payment, illegal use, owner move-in).
Succession Rights
If you've lived in a rent stabilized apartment for 2+ years, family members who've lived with you can "succeed" to your lease if you move out or pass away.
Preferential Rent
Some landlords charge less than the legal maximum rent—this is called "preferential rent." Before 2019, landlords could raise preferential rent to the legal rent upon renewal. Now, preferential rent is permanent for the duration of your tenancy.
Check your lease: If your lease shows both a "legal rent" and a lower "preferential rent," your rent can only increase by the RGB percentage from your preferential rent, not the legal rent.
Common Rent Stabilization Scams
Unfortunately, some landlords illegally deregulate apartments or overcharge tenants. Watch for:
Illegal Deregulation
Landlord claims apartment was "deregulated" before 2019. This was only legal under specific circumstances (rent over $2,774 AND high-income tenant). Many deregulations were fraudulent.
Inflated IAI Charges
Landlords claim they made improvements worth $50,000 between tenants to justify rent increases. Request receipts and verify work was actually done.
Missing Rent Stabilization Rider
Landlord "forgets" to include the rent stabilization rider in your lease, then claims the apartment isn't stabilized. The apartment's status is based on the building, not the lease language.
What to Do If You're Being Overcharged
If you believe your rent is higher than legally allowed:
- Request your rent history from DHCR
- Compare your current rent to the legal rent shown
- File a complaint with DHCR if there's a discrepancy
- You may be entitled to a rent reduction and refund of overcharges
Overcharge complaints can go back 6 years (or longer in cases of fraud). Tenants have recovered tens of thousands of dollars in overcharges.

Can my landlord refuse to renew my rent stabilized lease?
Only for specific legal reasons: non-payment, illegal use of apartment, nuisance behavior, or owner/family move-in (with restrictions). They must provide proper notice and you have the right to challenge in housing court.
What if my building was built after 1974?
It might still be stabilized if it received 421-a or J-51 tax benefits. Check DOF property records or request the rent history from DHCR.
Can I inherit a rent stabilized apartment?
Yes, through succession rights. Family members (including non-traditional family) who have lived in the apartment for 2+ years can succeed to the lease.
What's the difference between legal rent and preferential rent?
Legal rent is the maximum allowed under rent stabilization. Preferential rent is a lower amount the landlord agreed to charge. Since 2019, preferential rent is locked in for your entire tenancy.
My landlord says the apartment was deregulated. How do I verify?
Request the rent history from DHCR. It will show if and when any deregulation occurred. Many "deregulations" before 2019 were done improperly and can be challenged.
