The legal regulated rent on a New York City stabilized apartment is the maximum monthly amount your landlord can lawfully charge, as recorded in the unit’s registration with the state Division of Housing and Community Renewal (DHCR).1NYC Administrative Code § 26-512 It starts with the rent in effect when the apartment first entered stabilization and grows only through lawful increases layered on year by year: Rent Guidelines Board percentages at renewal, and approved surcharges for building or apartment improvements. If the number on your lease or the amount you pay each month doesn’t match what DHCR has on file, you may be paying too much.
Is Your Apartment Rent-Stabilized
Rent stabilization generally covers apartments in buildings with six or more units built before 1974, plus newer buildings whose owners receive certain tax exemptions in exchange for keeping rents regulated. Roughly one million New York City apartments fall under these rules. If your building has fewer than six units, or was built after 1974 without a tax benefit program, stabilization likely does not apply, and the rules below don’t govern your rent.
Rent control is a separate, older system for buildings built before February 1, 1947 where a tenant has been in continuous occupancy since before July 1, 1971. DHCR sets a maximum base rent and a maximum collectible rent for each rent-controlled unit individually, rather than through the Rent Guidelines Board process. Once a rent-controlled tenant leaves, the apartment usually converts to rent stabilization.
The fastest way to confirm your apartment’s status is to request its rent history from DHCR. You can submit the request online through the HCR portal, email rentinfo@nyshcr.org, or call 833-499-0343. If the unit is stabilized, a printed history arrives in the mail with every rent the landlord has registered. If it isn’t stabilized, you won’t hear back. The silence is the answer.
How the Legal Regulated Rent Is Built
Under NYC Administrative Code § 26-512, the legal regulated rent is the rent in effect when the apartment first became stabilized, plus every lawful adjustment since.1NYC Administrative Code § 26-512 Each change gets recorded through DHCR’s annual registration process, and that registration is what makes the rent legally what it is.
Landlords must register every stabilized unit with DHCR each year. A landlord who fails to file a timely registration cannot collect Rent Guidelines Board increases during the gap. Filing late removes that penalty going forward, but only if every increase during the missed period was otherwise lawful. The result is a running paper trail: the registration history is the document you use to check whether your rent is right.
What Can Lawfully Raise the Rent
Rent Guidelines Board Increases
The Rent Guidelines Board meets once a year and votes on the percentage a landlord can add when a stabilized tenant renews. Under Order #57, for leases starting between October 1, 2025 and September 30, 2026, the increase is 3% on a one-year renewal and 4.5% on a two-year renewal. A legal regulated rent of $2,000 would rise to $2,060 on a one-year lease or $2,090 on a two-year lease. You have the right to pick either term.
In New York City, landlords must offer a renewal lease in writing between 150 and 90 days before the current lease expires. Outside the city, the window is 120 to 90 days and notice must go by certified mail. You then have 60 days to choose a term, sign, and return the lease. Missing that window can expose you to eviction proceedings.
Major Capital Improvements
Major Capital Improvements (MCIs) cover building-wide work like a new boiler, new windows, or a new roof. The landlord must apply to DHCR for approval before passing any cost through to tenants. Even once approved, the increase is capped at 2% of the tenant’s current rent per year in New York City, down from the 6% cap that existed before 2019.
MCI costs are spread over 12 years for buildings with 35 or fewer units and 12.5 years for larger buildings. After 30 years from the date the increase first took effect, the MCI surcharge must come off the rent entirely. Before 2019, MCI increases were permanent.
Individual Apartment Improvements
Individual Apartment Improvements (IAIs) are upgrades inside a specific unit, such as new kitchen cabinets, a bathroom renovation, or replacement flooring, usually done while the apartment is vacant or with the tenant’s written consent. The total cost is capped at $15,000 within any 15-year period, and no more than three separate IAIs are allowed in that window.
The monthly rent increase from an IAI is the total cost divided over 168 months (14 years) for buildings with 35 or fewer units, or 180 months (15 years) for larger buildings. The surcharge must be removed after 30 years. Landlords have to produce detailed invoices and proof of payment; vague renovation claims will not survive DHCR review.
Preferential Rent
Preferential rent means the landlord is charging you less than the legal regulated rent. Your lease will usually list both figures. The two numbers matter because of what they used to allow, and what they now don’t.
Before 2019, a landlord could pull the preferential rent away at renewal and jump you up to the full legal regulated rent in a single lease cycle. The Housing Stability and Tenant Protection Act of 2019 ended that. If you were paying a preferential rent as of June 14, 2019, your renewal increases apply to the preferential rent, not to the higher legal figure. Once you vacate, though, the landlord can charge the next tenant up to the full legal regulated rent, so the protection follows you, not the apartment. That’s why the legal figure on your lease still matters even when you pay less: it’s the ceiling if the preferential arrangement ever ends.
How to Check Your Rent Against the Records
Start with your lease. A rent-stabilized lease should state the legal regulated rent, and if you have a preferential rent, both numbers should appear. Compare them to what you actually pay each month.
Then pull your apartment’s full rent registration history from DHCR through the HCR portal, by email at rentinfo@nyshcr.org, or by phone at 833-499-0343. The history will be mailed to you. Walk through it line by line. Each year’s registered rent should equal the prior year’s rent plus no more than the applicable Rent Guidelines Board percentage, with any approved MCI or IAI surcharge itemized separately. If a year shows a jump that can’t be explained by a lawful increase, that’s the signal to look closer.
Filing an Overcharge Complaint
If the numbers don’t add up, you can file DHCR Form RA-89, the Tenant’s Complaint of Rent Overcharge. DHCR recommends filing through its online portal. Submit all supporting documentation with the complaint rather than planning to add it later: your current lease, any prior leases, the rent registration history, and bank statements or canceled checks showing what you actually paid. Once DHCR dockets the complaint, you’ll receive an acknowledgment with a docket number for tracking.
How DHCR Calculates the Overcharge
DHCR determines the legal regulated rent by looking at the most recent reliable annual registration filed six or more years before the complaint, then tracing every lawful increase forward from that point. You can file at any time, but recovery of overcharge penalties is limited to the six years preceding the filing date. DHCR can examine any rent history it considers reasonably necessary, including records from other agencies and documents held by the owner or tenant.
If DHCR finds an overcharge, the default penalty is three times the overcharge amount, or treble damages. The landlord can reduce that to the overcharge plus interest by proving, by a preponderance of the evidence, that the overcharge was not willful. Voluntarily lowering the rent or offering a refund after you file does not count as proof the overcharge was unintentional. The landlord may also be ordered to pay your reasonable attorney’s fees and costs.
What to Expect
The review process is slow. Expect anywhere from six months to over a year. DHCR notifies the landlord and gives them a chance to respond with their own records, and the exchange continues until an administrator issues a final determination. If DHCR rules in your favor, it issues an order directing the landlord to drop the rent to the correct level and refund or credit the overcharge. Landlords who ignore these orders face further administrative penalties and potential court enforcement.
Retaliation Is Prohibited
Filing an overcharge complaint is a legally protected action. Under Real Property Law § 223-b, a landlord cannot serve an eviction notice, refuse to renew your lease, or substantially alter the terms of your tenancy in retaliation for a good-faith complaint to DHCR or any government authority about a legal violation.2NY Real Property Law § 223-b
If a landlord takes any of those actions within one year after you file, the law creates a rebuttable presumption of retaliation, and the burden shifts to the landlord to prove a legitimate, non-retaliatory reason. Keep written records of every communication with your landlord: dated emails, letters, and notes of conversations. If the timeline between your complaint and the landlord’s response ever needs to be proven, those records are what you’ll rely on.
