Is Your NYC Apartment Secretly Rent-Stabilised? Here's How to Find Out.
Millions of NYC renters are paying more than the legal limit and don't know it. The DHCR rent history check takes 5 minutes and could uncover years of overcharges.
Approximately one million apartments in New York City are rent-stabilised. Hundreds of thousands of tenants living in them do not know it — and a significant fraction of those are paying above the legal regulated rent. This is not a small oversight. Illegal deregulation and rent overcharges are among the most common forms of tenant exploitation in NYC, and since the Housing Stability and Tenant Protection Act of 2019 closed the major loopholes, tenants can now recover overcharged rent going back six years. This guide shows you exactly how to find out if your apartment is stabilised, what your legal rent should be, and what to do if you have been overcharged.
Step 1: Check If Your Building Is Covered
Rent stabilisation applies to apartments in buildings with 6 or more units, built before 1974, in New York City — unless the building received a tax exemption (like 421-a or J-51) that brought it under stabilisation regardless of age. The fastest way to check your specific building:
- Search your address on BuildingHealthX — the building profile shows rent stabilisation status derived from DHCR registration data.
- Search the DHCR Building Search at apps.hcr.ny.gov — enter your address and see if the building is registered as stabilised.
- Check your lease: rent-stabilised leases must use the DHCR standard lease rider and state that the apartment is rent-stabilised. If yours does not mention stabilisation and your building qualifies, that is a red flag.
- Look at your rent history: if the legal regulated rent is not shown in your lease, that is another indicator something may be wrong.
Step 2: Request Your Official DHCR Rent History
Get the apartment's complete registered rent history
Even if you know the building is stabilised, you need the specific apartment's rent history to verify whether you are being charged the legal regulated rent. This history goes back to 1984 and is your most powerful document.
- Go to apps.hcr.ny.gov/BuildingSearch and search your building address.
- Once the building appears, look for your specific unit number and request the rent history — it is free and you will receive it by mail within a few weeks.
- Alternatively, call DHCR directly at (718) 739-6400 to request a rent history over the phone.
- The rent history will show every registered legal rent for your apartment going back to the earliest registration, and any major capital improvement (MCI) increases or individual apartment improvement (IAI) increases that were used to raise the rent.
Request the rent history before you sign a new lease, not after. Once you have signed and moved in, discovering an overcharge becomes a dispute process. Before signing, a discrepancy gives you negotiating power — or a reason to walk away.
Step 3: How to Spot an Illegal Overcharge
Compare the registered rent history against your current lease rent. Allowable increases between tenancies are set annually by the NYC Rent Guidelines Board (RGB) — the board publishes the legal percentages going back decades. Any increase that exceeds the RGB guidelines without a documented MCI or IAI application is potentially an overcharge.
| Legal reason for rent increase | What it requires | Red flag |
|---|---|---|
| Annual RGB guidelines (renewal) | Set each year — typically 1–4% | Any increase above the RGB number without documentation |
| Vacancy bonus (pre-2019) | Was allowed before HSTPA 2019 — now eliminated | Any vacancy increase claimed after June 2019 is illegal |
| Major Capital Improvement (MCI) | Requires DHCR approval and a filed application | Increase claimed without a DHCR MCI order on record |
| Individual Apartment Improvement (IAI) | Post-2019: limited to $15,000 over 15 years max | Any IAI increase without documented renovation receipts |
| High-rent deregulation | Eliminated by HSTPA 2019 — previously allowed at $2,774+ | Any apartment claimed as deregulated via high-rent threshold after June 2019 |
Check your building's full history — violations, rent records, and court filings — in seconds.

Step 4: Filing an Overcharge Complaint
File a DHCR overcharge complaint
If you have identified that you are being charged more than the legal regulated rent, file a rent overcharge complaint with DHCR using Form RA-89. You do not need an attorney to file, and there is no filing fee.
- Download Form RA-89 from hcr.ny.gov or pick it up at any DHCR borough office.
- Attach: your rent history printout, copies of all lease renewals showing rent amounts, and any DHCR correspondence you have received.
- DHCR will investigate and calculate the legal regulated rent. If they find an overcharge, they can order the landlord to refund up to 6 years of excess payments.
- For wilful overcharges (where DHCR finds the landlord deliberately overcharged), you may be entitled to treble damages — three times the amount overcharged per year.
- You can also file in Housing Court instead of DHCR, which is sometimes faster. A tenant attorney can advise on the better route for your specific situation.
If your landlord has told you the apartment is 'market rate' or 'deregulated,' do not simply accept this without verifying. The 2019 HSTPA made most high-rent deregulation illegal going forward, and apartments that were improperly deregulated before 2019 are being restored to stabilisation by DHCR and Housing Court decisions regularly. The DHCR rent history is the ground truth — your landlord's claim is not.
Frequently asked questions about rent stabilisation in NYC
How do I know if my apartment is rent-stabilised if my lease doesn't say so?
Request the DHCR rent history for your apartment at apps.hcr.ny.gov. If the apartment is registered as rent-stabilised, the history will show it. Additionally, search your building address on HPD Online — buildings with six or more units built before 1974 are generally covered unless they received specific exemptions. A missing stabilisation rider in your lease when the apartment should be covered is itself a potential violation worth pursuing.
My landlord says the apartment was deregulated because the rent was above $2,774. Is that valid?
It depends on when the alleged deregulation occurred. The high-rent vacancy deregulation threshold was eliminated by the Housing Stability and Tenant Protection Act of 2019. Any deregulation claimed to have occurred after June 14, 2019 based on rent level is invalid. If the landlord claims deregulation happened before 2019, you can still challenge whether it was properly done — DHCR records and rent histories are the verification tool.
I've been overcharged for 3 years. How much can I recover?
You can recover overcharged rent going back up to 6 years. For each year, you get the overcharged amount. If DHCR finds the overcharge was wilful, you receive treble damages — three times the annual overcharge per year of wilful violation. The landlord is also required to roll your rent back to the legal regulated amount going forward. Depending on the scale of the overcharge, this can be a significant recovery — some tenants have recovered $20,000–$50,000+ in overcharged rent.
Can my landlord evict me for filing a rent overcharge complaint?
No. Retaliatory eviction in response to a rent overcharge complaint is illegal under New York Real Property Law §223-b. If your landlord attempts eviction, raises your rent, or reduces services within 180 days of your complaint, there is a legal presumption of retaliation. Document everything. A retaliatory eviction attempt after a DHCR complaint often strengthens your overall case.
My building got a 421-a tax exemption when it was built. Does that mean I'm rent-stabilised?
Possibly, yes. Buildings that received 421-a tax exemptions are required to register their apartments as rent-stabilised for the duration of the exemption period — which can be 10, 15, 25, or 35 years depending on the specific exemption granted. Many newer luxury buildings in NYC have rent-stabilised apartments because of 421-a, even if the landlord markets them as luxury market-rate units. Check the DHCR registration and HPD's 421-a compliance records for your building.
