NYC Rent Stabilization FAQ

Rent stabilization limits the amount landlords can increase rent for covered apartments. Annual increases are set by the Rent Guidelines Board (RGB). Tenants in stabilized apartments have the right to lease renewal and cannot be evicted without cause.

Generally: buildings with 6+ units built before January 1, 1974, and buildings that received 421-a or J-51 tax benefits. Some newer buildings have stabilized units through regulatory agreements. Individual apartment deregulation has been largely eliminated by HSTPA 2019.

HSTPA 2019 eliminated vacancy decontrol (no more deregulation at $2,774 threshold), eliminated vacancy bonuses, severely limited Individual Apartment Improvements (IAI) to $15,000 over 15 years, limited Major Capital Improvements (MCI) increases, and made preferential rent the base for future increases.

The Rent Guidelines Board (RGB) sets maximum increases annually for one-year and two-year lease renewals. Recent increases have ranged from 0% to 5% depending on the year. These limits apply only to lease renewals — initial rents may be negotiated.

A preferential rent is a rent charged below the legal regulated rent. Under HSTPA 2019, the preferential rent (not the legal rent) becomes the base for calculating future increases, significantly limiting a landlord's ability to raise rents to the legal maximum.

IAI allows landlords to increase the legal regulated rent after making improvements to individual apartments. Under HSTPA 2019, IAI is capped at $15,000 over 15 years, with the increase limited to 1/168th (or 1/180th for buildings with 35+ units) of the cost per month.

MCI allows rent increases for building-wide improvements like new boilers, roofs, or plumbing. Under HSTPA 2019, MCI increases are capped at 2% per year, with total increases limited over 30 years. The increase is now temporary, not permanent.

Check the HPD building registration, request a DHCR rent history, review DOF tax bills for stabilized unit counts, and check for 421-a/J-51 benefits. RegWatch includes building characteristics and tax benefit data that help identify stabilized buildings.

Under HSTPA 2019, high-rent vacancy decontrol was eliminated, meaning apartments generally remain stabilized regardless of rent level. The only path to deregulation is typically co-op/condo conversion (with tenant consent) or demolition.

HSTPA 2019 significantly impacted multifamily property values by limiting income growth potential. Below-market rents with restricted increases mean lower net operating income and higher cap rates. Investors must carefully analyze rent rolls and stabilization status.

The RGB is a nine-member board appointed by the Mayor that sets maximum rent increases for stabilized apartments annually. Members include tenant representatives, landlord representatives, and public members. Hearings are held each spring.

RegWatch includes building characteristics, unit counts, tax benefit data (421-a, J-51), and HPD registration information that help identify rent-stabilized buildings. This is essential context for evaluating residential investment properties.
