57th Street is a tenement, approximately 130 years old, located in Manhattan’s west side, adjoining the Clinton historic preservation area. The building, predominantly occupied by rent-control and rent-stabilized tenants, is contiguous to two structures also owned by petitioners, 400 and 404 West 57th Street, which contain primarily single-room occupancy units. Although all three buildings have common ownership and are not separated either by open space or zoning lot lines, only 25 feet of 400 West 57th Street is within the Special Clinton District. The owners seek removal of all tenants in advance of major structural alterations and repairs, which they claim to be necessary to rectify the unsafe condition of the building, a condition hazardous to occupants and placing the building in imminent threat of collapse. On December 23,1981, the department of buildings issued an alteration permit following the filing of an application and plans, which proposed major renovation work and the issuance of a new certificate of occupancy for a single building. After an inspection by the department, notices of violation were issued, the inspectors concluding that it was unnecessary to vacate the premises to perform the work. Accordingly, on April 30,1982, the city revoked the alteration permit, asserting that there had been noncompliance with zoning resolution section 96-109, which, for a building located within the preservation area of the Special Clinton District, required prior certification from the housing administrator that there had been no tenant harassment. In that period, petitioners had been found guilty of criminal contempt for harassing tenants (Civil Ct, New York County, Housing Part 49-D, Sept. 21,1981, George, H. J.). During the pendency of this appeal that order was modified by the Appellate Term, First Department (May 24, 1983) to the extent of striking the decretal paragraph finding that the owner was in contempt. Three subsequent inspections by the office of the Manhattan borough superintendent found violations but again concluded that there was no evidence of structural failure so as to warrant evacuation of the building, albeit the violations were found to require immediate remedial work which the department determined could be performed without the tenants vacating the premises. This proceeding was commenced on June 21,1982, the petition seeking a stay of the order of the city to effect immediate repairs and to compel the city to issue a vacate order. Most of the remaining tenants, who moved to intervene, opposed issuance of a vacate order or an alteration permit, contending that such an order or permit would interfere with their occupancy. They argued that the owner did not intend to correct the violations but planned to convert- the premises to luxury housing accommodations and, for that purpose, sought to remove control and stabilized tenants therefrom. In support of their position, the tenants referred to the fact that after the original, August, 1980 application by the landlord to permit the alteration had been denied, 52 holdover proceedings were commenced, all of which were dismissed. They claim that, subsequently, the landlord offered each of the remaining tenants monetary settlements to quit possession. The record reflects that the parties are in agreement as to the need for substantial repairs. They disagree, however, as to whether the extent of the violations rendered the building hazardous to continued occupancy and whether removal of the tenants was necessary to effect structural alterations. Special Term held it was unnecessary for petitioners to exhaust their administrative remedies by pursuing an appeal to the Board of Standards and Appeals from the refusal of the department of buildings to issue á vacate order and the revocation of the alteration permit. Thus, the court sustained mandamus as an available remedy to compel performance of a nondiscretionary act and to correct an emergency situation where there was a possibility of irreparable harm
(Watergate II Apts, v Buffalo Sewer Auth., 46 NY2d 52 ). In so holding, Special Term concluded that the adjoining structures were to be considered as one building for zoning purposes
