New York Rent Increase Rules for Landlords

Understanding Rent Stabilization Coverage

New York's rent stabilization system is the largest regulatory framework of its kind in the United States, covering approximately one million apartments in New York City alone. Rent stabilization applies to apartments in buildings with six or more units built between February 1, 1947, and December 31, 1973, or in buildings constructed after 1973 that received certain tax benefits such as 421-a or J-51 abatements. Buildings with six or more units built before 1947 may fall under the even more restrictive rent control system.

The Housing Stability and Tenant Protection Act of 2019 permanently eliminated two key provisions that previously allowed landlords to deregulate apartments: high-rent vacancy decontrol and high-income decontrol. Before the HSTPA, apartments that reached a threshold rent could be deregulated upon vacancy. Now, once an apartment is stabilized, it remains stabilized permanently regardless of the rent level or tenant income. This change has significant long-term implications for property valuations and investment returns.

Landlords can determine whether a specific unit is rent-stabilized by checking the building's registration with the New York State Division of Housing and Community Renewal (DHCR). Every rent-stabilized unit must be registered annually, and the landlord must provide each tenant with a copy of the apartment registration showing the legal regulated rent. Failure to register can result in rent freezes and penalties.

Rent Increase Guidelines

Annual rent increases for rent-stabilized apartments are set by the Rent Guidelines Board (RGB), which issues an order each year specifying the permissible percentage increase for one-year and two-year lease renewals. The RGB considers factors including the Consumer Price Index, operating cost increases, vacancy rates, and available housing data. Recent RGB orders have typically permitted increases ranging from 1% to 5% for one-year renewals.

The HSTPA eliminated vacancy bonuses and longevity increases that previously allowed landlords to raise the legal regulated rent by 20% upon vacancy and an additional percentage based on the time since the last vacancy increase. These provisions had been the primary mechanisms landlords used to increase rents toward the decontrol threshold. Their elimination means regulated rents increase much more slowly over time.

Individual Apartment Improvements (IAIs) remain available but are significantly restricted under the HSTPA. Landlords may increase rent to recover the cost of qualifying improvements to individual apartments, but the increase is limited and spread over the useful life of the improvement (generally 15 years in buildings with 35 or fewer units, or 12 years in larger buildings). The total IAI increase over any 15-year period is capped at $15,000. All IAI work must be documented and the tenant must consent to the improvements.

Lease Renewal Requirements

Landlords of rent-stabilized apartments must offer lease renewals on the same terms and conditions as the expiring lease, with the rent increase limited to the RGB guidelines. The renewal offer must be served between 150 and 90 days before the existing lease expires, using the DHCR renewal lease form. The tenant has 60 days to accept the renewal. If the tenant fails to respond within 60 days, they are deemed to have accepted the renewal on the same terms.

Landlords cannot refuse to renew a rent-stabilized lease except on limited grounds including owner occupancy (limited to a single unit per building), demolition with appropriate permits, and nonprimary residence by the tenant. The nonprimary residence ground requires the landlord to prove that the tenant does not use the apartment as their primary home, which typically requires evidence that the tenant lives elsewhere for the majority of the year.

Any changes to lease terms at renewal must be consistent with the Rent Stabilization Code. Landlords cannot add unreasonable or burdensome new provisions. Services provided under the existing lease must be maintained; any reduction in services constitutes a rent overcharge and can be challenged by filing a complaint with DHCR. Tenants who believe their renewal terms are improper should seek guidance from DHCR or a tenant rights organization.

Record-Keeping and Compliance

Landlords of rent-stabilized properties face extensive record-keeping requirements. Annual apartment registration with DHCR is mandatory, and the registration must reflect the current legal regulated rent and all adjustments made during the year. Landlords must maintain complete rent histories and documentation supporting every rent increase, including RGB orders, IAI documentation, Major Capital Improvement (MCI) approvals, and any preferential rent agreements.

The HSTPA extended the lookback period for rent overcharge claims from four years to six years, and in some cases courts may examine the entire rent history if fraud is alleged. This expanded lookback means landlords must retain records going back at least six years to defend against overcharge claims. Failure to produce documentation supporting a rent increase creates a rebuttable presumption that the increase was improper.

Compliance with rent stabilization is enforced by DHCR through tenant complaints and periodic audits. Violations can result in rent rollbacks, treble damages for willful overcharges, and civil penalties. Landlords who consistently fail to comply with registration and record-keeping requirements may face additional enforcement actions. Given the complexity of rent stabilization law, many landlords engage property management companies or attorneys who specialize in regulated housing to ensure compliance.
