Is my apartment rent stabilized? A step-by-step test
Answer a few questions to see how likely your NYC apartment is rent stabilized: building age, size, tax benefits, the HCR list and your lease. Then confirm.
6 min read · Updated
Your apartment is probably rent stabilized if it is in a New York City building with six or more apartments built before 1974, or in a building that receives a 421-a or J-51 tax benefit. The only official answer comes from New York State Homes and Community Renewal (HCR), which will mail you the apartment's registered rent history if it is stabilized; the test below tells you how likely it is before you ask.
The Rent Guidelines Board estimates that about one million NYC apartments are rent stabilized. Stabilization limits rent increases at renewal to the rates the Board sets, gives you the right to a one- or two-year renewal lease, and limits evictions to grounds allowed by law. If you are paying for an apartment that should be stabilized but isn't treated that way, you may be overpaying.

The official criteria, in plain English
HCR's Fact Sheet #1 says rent stabilization generally covers buildings built after 1947 and before 1974, apartments that left rent control, and buildings that receive J-51, 421-a and 421-g tax benefits (each with its own rules). The city's rent stabilization page adds that stabilized apartments are most often in buildings with six or more units built before 1974. Buildings built before 1947 with six or more units are also commonly stabilized, because apartments that leave rent control generally become stabilized.

|---|---|---|
| Lease rider or “rent stabilized” on the lease | Strong sign. Owners must attach the HCR lease rider to stabilized leases. | Your lease papers |
| Building has 6+ apartments, built before 1974 | Meets the main rule; many units qualify | Roofy building page, NYC property records |
| 421-a or J-51 tax benefit | Stabilized while the benefit applies, under program rules | Lease/rider, building tax records |
| On the HCR/RGB building list | At least one unit was registered as stabilized | RGB borough lists; Roofy building page |
| Rent in dollars and cents (e.g. $2,176.43) | Typical of percentage-based guideline increases | Your lease |
| Annual registration copy from the owner | Owners must give tenants a copy of the yearly registration | Your mail from the landlord |
| Building is a co-op or condo | Mixed: pre-conversion tenants often stay stabilized | Ask HCR |
| 1–2 family house, or 3–5 units built after 1973 with no tax benefit | Generally not stabilized | — |

What changes if your apartment is stabilized
- Renewal increases are capped at the Rent Guidelines Board rates. For leases starting October 1, 2026 through September 30, 2027, the Board voted 0% for both one- and two-year leases. Use the renewal calculator or read about the 2026 rent freeze.
- You have a right to renew for one or two years, your choice.
- Evictions are limited to grounds allowed by law.
- Preferential rents are protected: if you pay less than the legal rent, increases at renewal are based on what you pay. See the preferential rent calculator.
- You can file complaints with HCR for overcharges, lease violations and reduced services.
