In case any land is used or structure is erected, constructed, altered or maintained in violation of this chapter, any regulation made pursuant thereto or any detailed statement or plan submitted and approved thereunder, in addition to other lawful remedies any appropriate action or proceedings may be instituted to prevent such unlawful use, erection, construction, alteration or maintenance, to restrain, correct or abate such violation, to prevent the occupancy of such structure or land or to prevent any illegal act, conduct, business or use in or about such premises. Whenever the Commissioner of the Department of Housing and Buildings has reasonable grounds to believe that work on any structure is being prosecuted in violation of the provisions of this chapter, or not in conformity with any regulation made pursuant thereto or not in compliance with any detailed statement or plan submitted and approved thereunder, or in an unsafe and dangerous manner, he may issue a stop-work order.
