Article 210 Illegal Conversions

It shall be unlawful, except in accordance with all requirements of this code, to convert any dwelling for occupancy by more than the legally authorized number of families or to assist, take part in, maintain or permit the maintenance of such conversion. Upon the finding of such violation and the imposition of punishment for such violation as set forth in this code the department or if applicable the environmental control board shall forward to the internal revenue service, the New York state department of taxation and finance and the New York city department of finance the name and address of the respondent or defendant, the address of the building or structure with respect to which the violation occurred and the time period during which the violation was found to have existed.

Upon receiving a complaint of a condition relating to a building or part thereof that would, if observed by the commissioner, be identified by the commissioner as a violation of section 28-210.1 involving the illegal conversion, maintenance or occupancy of three or more dwelling units than are legally authorized by the certificate of occupancy or if no certificate of occupancy is required as evidenced by official records, the commissioner shall attempt to enter and inspect such building or part thereof. After two unsuccessful attempts to gain access to such building or part thereof, the commissioner shall request the corporation counsel to make an application in any court of competent jurisdiction for an ex parte administrative warrant directing the entry and inspection of such premises or location and to issue violations found upon access to such premises or locations. In preparing such requests, priority may be given by the commissioner to requests based on the degree of hazard to safety or property that the commissioner believes present. Such counsel shall promptly consider such request, and where such counsel determines that there is appropriate basis to obtain such an order, shall seek such an order. The commissioner shall promptly execute any such order in accordance with its terms.
