Rent-stabilized vs. rent-controlled apartments are the two tiers of New York’s rent regulation system, and the practical difference comes down to who qualifies and how rents are set. Rent control is a narrow, shrinking category for tenants in pre-1947 buildings who have lived there continuously since before July 1, 1971, with no lease and rents set by a legal formula. Rent stabilization is far broader, covering just under one million New York City apartments, with formal leases, renewal rights, and annual increases capped by a public board. Roughly 24,000 apartments remain rent-controlled citywide.
Both systems exist primarily in New York City, and the rules below are New York rules. Other states and cities have their own rent regulation schemes, but the specific two-tier “control” and “stabilization” framework is a New York creation.
Who Qualifies for Rent Control
Rent control is the older and stricter of the two systems, rooted in post-World War II housing shortages. Two conditions must both be met: the building was constructed before February 1, 1947, and the tenant (or a qualifying family member) has lived in the apartment continuously since before July 1, 1971. That residency cutoff is why the pool keeps shrinking. When the original tenant dies or permanently moves out, the apartment almost always leaves rent control.
Rent-controlled tenants don’t sign leases. They live under what the law calls a statutory tenancy, meaning the right to remain comes from the statute itself rather than a contract with the landlord. Rents are set by formula, not by market conditions.
What Happens When a Rent-Controlled Tenant Leaves
Once a rent-controlled tenant permanently vacates, the apartment is decontrolled. In buildings with six or more units, the apartment typically rolls into rent stabilization. The landlord can set the initial rent at whatever the market will bear, but the incoming tenant has the right to file a Fair Market Rent Appeal to challenge that figure. In buildings with fewer than six units, the apartment usually leaves rent regulation entirely and becomes market-rate.
Who Qualifies for Rent Stabilization
Rent stabilization generally applies to apartments in buildings with six or more units that were built before January 1, 1974. It also covers units in newer buildings that received certain tax benefits, including the 421-a program, which required all rental units to remain stabilized for the duration of the tax abatement. In some cases, affordable units had to stay stabilized for 35 or 40 years.
Stabilized tenants hold formal leases and have the right to choose between a one-year and a two-year renewal term. Landlords set the rent within annual limits, and they cannot refuse to renew simply because they’d prefer a higher-paying tenant.
Deregulation Is No Longer an Easy Exit
Before 2019, landlords could pull an apartment out of rent stabilization once the rent crossed a certain dollar threshold or when a high-income tenant vacated. The Housing Stability and Tenant Protection Act of 2019 eliminated both high-rent vacancy deregulation and high-income deregulation. Apartments that are currently stabilized stay stabilized regardless of what the rent reaches.
How Rent Increases Work
The mechanics of rent increases are where the two systems diverge most sharply.
Rent-Stabilized Increases
Each year, the New York City Rent Guidelines Board reviews operating costs, inflation, and other economic data, then votes on the maximum percentage a landlord can add to a stabilized lease at renewal. For leases beginning between October 1, 2025 and September 30, 2026, the board approved a 3% increase for one-year renewals and 4.5% for two-year renewals. A landlord cannot charge more than these caps, though they can charge less.
Rent-Controlled Increases
Rent-controlled apartments follow a different formula. The annual increase is capped at the lesser of 7.5% or the average of the five most recent one-year Rent Guidelines Board increases. In practice, this usually produces a smaller bump than the 7.5% ceiling, because recent RGB increases have been modest.
Major Capital Improvements
Beyond the annual guidelines, landlords in both systems can apply for rent increases tied to Major Capital Improvements, meaning building-wide upgrades like a new boiler, roof, or elevator. If approved, MCI surcharges are capped at 2% of a tenant’s rent per year and must be removed from the rent 30 years after they take effect. Before 2019, MCI increases were permanent, so the sunset and the annual cap are relatively recent protections.
Preferential Rent
Some stabilized tenants pay a preferential rent, which is a price below the maximum legal rent the landlord could charge. Before 2019, landlords could jump up to the full legal rent at renewal. The Housing Stability and Tenant Protection Act changed that: any tenant paying a preferential rent on or after June 14, 2019 keeps that lower rate for the entire tenancy. Future RGB increases are calculated from the preferential rent, not the higher legal rent. The landlord can only charge the full legal rent after the tenant permanently vacates.
Lease Renewals and Eviction Protections
Rent-controlled tenants never deal with lease renewals. Their statutory tenancy gives them an ongoing legal right to remain, and the landlord cannot end that occupancy except through narrow legal channels.
Rent-stabilized tenants have a right to a renewal lease, and the process follows a strict timeline. The landlord must send a written renewal offer between 150 and 90 days before the current lease expires. The tenant then has 60 days to sign and return it. A tenant who lets that 60-day window pass without responding can lose the right to renew, and the landlord may begin eviction proceedings after the lease ends.
Under both systems, landlords can only evict on limited grounds. The most common are nonpayment of rent and lease violations such as creating a nuisance. Landlords can also seek to recover a unit for their own personal use or for an immediate family member, and they can refuse renewal if they plan to demolish the building. Each of these grounds comes with strict requirements and is frequently contested.
Succession Rights
Both rent-controlled and rent-stabilized apartments allow a family member to take over the tenancy when the primary tenant dies or permanently moves out. The qualifying family member must have lived in the apartment as their primary residence for at least two consecutive years immediately before the tenant’s departure. If the family member is 62 or older, or is disabled, the required period drops to one year.
The definition of “family member” for succession purposes is broader than many tenants expect. It can include domestic partners and other household members who can show emotional and financial interdependence with the tenant, not only blood relatives or spouses. A family member asserting succession rights should notify the landlord by certified mail and be prepared to document both the relationship and the period of co-residency.
How to Confirm Which One You Have
The most reliable way to confirm whether your apartment is rent-stabilized or rent-controlled is to request its official rent history from the New York State Division of Housing and Community Renewal. You can submit the request through DHCR’s online inquiry portal, by visiting a borough rent office in person by appointment, or by mailing Form REC-1 (the Request for Records Access) to the Records Access Officer at DHCR’s Jamaica, Queens office. The form can also be emailed to ORArecords@hcr.ny.gov.
The rent history shows every rent registered for the apartment over the years, including each increase and the reason behind it. For a stabilized unit, it will show whether the apartment has been consistently registered and whether the increases charged match what the Rent Guidelines Board authorized. Numbers that don’t add up are the starting point for an overcharge complaint, which carries triple damages for a willful overcharge and reaches back up to six years. Rent-controlled apartments won’t appear in the stabilization registration system the same way, but DHCR can still confirm controlled status on request.
