Rent-Regulated Housing includes both "rent-controlled" and "rent-stabilized" apartments. Besides the benefit of rent increases that are set by a government agency, tenants in rent-regulated housing also have greater legal protections than those living in market-rate housing. For an apartment to be under rent control, the tenant (or the tenant's family if the apartment has been passed down to a qualified family member) must have been living in that apartment continuously since before July 1, 1971. When a rent-controlled apartment becomes vacant, it either becomes rent stabilized, or, if it is in a building with fewer than six units, it is generally removed from regulation. As a rule of thumb, rent stabilized apartments are in building built before 1974, have six or more apartments, and the new rent is below $2,000 per month. Apartments can also become rent stabilized if a developer utilizes the J-51 or 421-a tax incentive programs. Click here for a list of buildings in New York City with rent-stabilized apartments. Rent stabilized apartments comprise approximately 57% of rental apartments in the Bronx, 42% of apartments in Brooklyn, 59% of Manhattan apartments, 43% of Queens apartments, and 15% of Staten Island apartments.
