In case any building or structure is erected, constructed, reconstructed, altered, converted, located or maintained or any building, structure, land or premises is used or any land is divided into lots in violation of this chapter or any regulation made under authority conferred thereby, the Town Board or any Town officer designated by said Town Board or the Zoning Administrator, in addition to other lawful remedies, may institute any appropriate action or proceedings to prevent such unlawful erection, construction, reconstruction, alteration, conversion, repair, maintenance or use or division of land, to restrain, correct or abate such violation, to prevent the occupancy of such building, structure or land or to prevent any illegal act, conduct, business or use in or about such premises. Whenever either the Building Inspector or the Zoning Administrator has reasonable grounds to believe that work on any building or structure or land or use thereof is being performed in violation of the provisions of the applicable building laws, ordinances or regulations or not in conformity with the provisions of the application, plans or specifications on the basis of which a building permit or certificate of occupancy was issued or in an unsafe and dangerous manner, the Building Inspector or the Zoning Administrator shall notify the owner of the property, the owner's agent or the persons performing the work to suspend all building activities or uses specified in the stop order until the stop order has been rescinded. Such order and notice shall be in writing, shall state the conditions under which the work or use may be resumed and may be served upon a person to whom it is directed either by delivering it personally or by posting the same upon a conspicuous portion of the building or premises and sending a copy of the same by registered mail.
