The NYC preferential rent loophole works like this: while you live in your rent-stabilized apartment, the discounted rent you pay is locked in as the base for your renewals, but the day you move out, your landlord can reset the rent for the next tenant to the full legal regulated rent that has been climbing on paper the entire time you paid less. The 2019 Housing Stability and Tenant Protection Act closed the version of this loophole that used to hit sitting tenants, but the vacancy reset survived. Understanding how the gap between your actual rent and the legal regulated rent widens over time is the key to protecting yourself, your family, and anyone who might take over your apartment.
What Preferential Rent Is
Every rent-stabilized apartment has a legal regulated rent, which is the maximum a landlord can lawfully charge. That ceiling is registered with the state housing agency each year and grows through the annual adjustments set by the NYC Rent Guidelines Board. A preferential rent is simply a discount below that ceiling, an amount the landlord agrees to accept, often to fill a unit in a soft market.
The Rent Stabilization Code defines preferential rent as the amount “charged to and paid by the tenant” when it falls below the legal regulated rent for that apartment.1Cornell Law Institute. 9 NYCRR 2521.2 – Preferential Rents About 250,000 households across New York City pay a preferential rent.2City of New York. Protections for Rent-Regulated Tenants If you are one of them, two numbers on your lease matter: what you actually pay, and the higher legal regulated rent the landlord could theoretically charge.
The Vacancy Reset Is the Loophole
Every tenant protection around preferential rent is tied to you personally. When you move out, the landlord can charge the next tenant up to the full legal regulated rent that has been accruing on paper the entire time you paid less.1Cornell Law Institute. 9 NYCRR 2521.2 – Preferential Rents
Consider the math. Say you have been paying a preferential rent of $1,400 for a decade while the legal regulated rent climbed to $2,300 through annual adjustments. When you leave, the landlord can offer the apartment to the next person at $2,300. That is an instant $900 monthly jump, entirely legal, with nothing about the apartment changed.
The 2019 law softened one piece of this. Before the HSTPA, landlords could tack a separate vacancy bonus of roughly 20% on top of the legal regulated rent whenever a tenant left. That vacancy bonus no longer exists. The HSTPA eliminated the statutory vacancy rate entirely and does not allow the Rent Guidelines Board to establish a separate one.3New York State Homes and Community Renewal. Fact Sheet #05 – Vacancy Leases in Rent Stabilized Apartments The landlord can still reset to the legal regulated rent, but they can no longer pile additional increases on top of it.
What the 2019 Law Locked In While You Stay
Before 2019, preferential rent was a trap dressed as a deal. A landlord could offer a steep discount, then jack the rent to the full legal regulated amount on your very next renewal. The jump could double or triple your rent overnight. Families got priced out of apartments they had lived in for years.
The Housing Stability and Tenant Protection Act of 2019 ended that practice. Any tenant paying a preferential rent on or after June 14, 2019, keeps that preferential rent as the base for all future renewals, for as long as they remain in the apartment.4New York State Homes and Community Renewal. Fact Sheet #40 – Preferential Rents Rent Guidelines Board percentage increases now apply to the lower amount you actually pay, not the higher number on file.1Cornell Law Institute. 9 NYCRR 2521.2 – Preferential Rents The legal regulated rent remains on the books but stays untouchable while you live there.
One narrow exception: certain government-financed affordable housing programs may not be bound by this rule. If your building operates under a regulatory agreement with a government agency, contact that agency directly to confirm your rights.5Homes and Community Renewal.

Check Every Lease for Both Numbers
Both the preferential rent and the legal regulated rent are required to appear on your lease. The official HCR lease rider for rent-stabilized tenants states that “the legal regulated rent is required to be written into the vacancy lease and all subsequent renewal leases in order to be preserved.”6New York State Homes and Community Renewal. Lease Rider for Rent Stabilized Tenants This requirement applies to every renewal, not only the first lease.
Here is where the loophole can close on the landlord. If the owner fails to list both figures on the initial lease and every subsequent renewal, they may lose the right to charge the legal regulated rent when you eventually move out. The lease rider explicitly conditions the landlord’s ability to reset the rent upon vacancy on having “both the legal rent and the preferential rent listed in the initial lease offering the preferential rent and every subsequent lease offering the preferential rent until the vacancy.”6New York State Homes and Community Renewal. Lease Rider for Rent Stabilized Tenants Pull out every renewal lease you have signed. If the legal regulated rent is missing from any of them, that is worth raising with HCR or a housing attorney.
Succession Rights Can Prevent the Reset
Succession is one of the strongest ways to stop the loophole from ever triggering. Under the Rent Stabilization Code, qualifying family members who have lived in the apartment as their primary residence for at least two years, or one year for seniors and people with disabilities, can take over the lease when the tenant of record moves out or dies.7Homes and Community Renewal. Succession The definition of family member is broad and includes spouses, domestic partners, children, parents, siblings, and other individuals who can demonstrate emotional and financial interdependence.
Because succession is not a vacancy, the apartment stays continuously occupied, and the landlord cannot reset the rent to the legal regulated amount. The successor steps into the existing tenancy rather than starting a new one. If you are paying a preferential rent and a family member lives with you, making sure they meet the residency requirements is one of the most effective protections available.
Increases That Still Apply While You Live There
Locking in your preferential rent as the base does not mean your rent never goes up. Three types of lawful increases can still apply, and each one also raises the legal regulated rent on file, widening the gap the landlord can exploit when you leave.
Rent Guidelines Board Adjustments
Each year the RGB sets the maximum percentage increase landlords can impose on renewed leases. For leases starting between October 1, 2025, and September 30, 2026, the board adopted increases of 3% for a one-year renewal and 4.5% for a two-year renewal.8New York City Rent Guidelines Board. 2025-26 Apartment/Loft Order #57 These percentages apply to the preferential rent you actually pay, not the legal regulated rent. The legal regulated rent gets adjusted by the same percentages on paper, which is how the gap between the two numbers keeps growing year after year.
Major Capital Improvements
When a landlord makes a significant building-wide upgrade such as a new boiler, roof, or elevator modernization, they can pass a portion of the cost to tenants as a rent increase. The amount collected from each tenant is capped at 2% of their rent per year, and the increase must be removed from the rent 30 years after it became effective.9Homes and Community Renewal. Apartment (IAI) and Building (MCI) Improvements MCI increases also get factored into the legal regulated rent.
Individual Apartment Improvements
If the landlord renovates your specific apartment, say a new kitchen, bathroom, or flooring, they can raise the rent to recover part of the cost. The HSTPA capped the total recoverable amount at $15,000 over a 15-year period. The landlord must notify HCR by filing documentation and before-and-after photos through the Owner’s Rent Regulation Application system before collecting the increase.9Homes and Community Renewal. Apartment (IAI) and Building (MCI) Improvements IAIs most often happen between tenancies, when the apartment is empty and the landlord can renovate freely, so these increases usually show up as a higher starting rent for the next tenant.
Pull Your Rent History and File If the Numbers Are Wrong
If any of this makes you wonder whether your landlord has been registering the correct amounts, you can pull your apartment’s full rent history from HCR. The record shows every registered rent amount and service change going back decades, and it is the document that reveals whether the legal regulated rent on your lease actually matches what has been filed with the state.
The process starts with form REC-1, the Request for Records Access. You can submit it by email to ORArecords@hcr.ny.gov or mail it to the DHCR Office of Rent Administration at Gertz Plaza, 92-31 Union Hall Street, 6th Floor, Jamaica, NY 11433.10Homes and Community Renewal. Records Access You can also visit a borough rent office in person by appointment. Bring proof of identity and proof that you live in the apartment, such as a copy of your lease, a rent receipt, or a rent bill.11Homes and Community Renewal. Most Common Rent Regulation Issues for Tenants When records cannot be sent electronically, HCR charges 25 cents per page for paper copies, payable by check or money order.12New York State Homes and Community Renewal. Request for Records Access – REC-1
If your rent history shows you have been charged more than the legal amount, whether because the landlord raised your preferential rent above the allowable base, applied the RGB increase to the legal regulated rent instead of the preferential rent, or tacked on an unauthorized fee, you can file a formal overcharge complaint with HCR. The process uses form RA-89 for rent-stabilized apartments. HCR recommends filing online through their Rent Overcharge Application portal, though you can also submit the paper form by mail.13Homes and Community Renewal. Tenant/Owner Forms If HCR finds an overcharge, they can order the landlord to refund the excess rent and reset the legal rent going forward. Overcharge cases can also result in treble damages, three times the overcharge amount, if the landlord’s conduct was willful.
