Article 7-C of the New York Multiple Dwelling Law, commonly known as the 1982 Loft Law, was designed to protect the residential tenants of certain former commercial buildings in New York City from substandard conditions, eviction, and unfair rent increases. The law affected buildings it defined as Interim Multiple Dwellings (IMDs), commercial or manufacturing loft buildings that had at least three units occupied by residents during the period of April 1, 1980, through December 1, 1981. It required landlords to bring converted residences up to code, and prevented them from charging tenants for improvements until the issuance of a Certificate of Occupancy. The law was administered by the New York City Loft Board.
