Violations and penalty. Violation shall be determined by the Planning Administrator by an investigation of the fact and inspection of the premises, after which he shall give notice thereof in writing to the owner or to his duly authorized agent and to the occupant of the premises, and shall order that any use of any premises contrary to the provisions of Chapter
70, Zoning, shall immediately cease. Whoever violates any provision of Chapter
70, Zoning, or any of the conditions under which a permit is issued by the Building Commissioner, following certification by the Planning Administrator, permission granted by the Board of Appeals, or any decision rendered by the SPGA, or DPRA, shall be liable to a fine as provided in the Noncriminal Disposition Bylaw for each violation. Each day of violation after such written notice will be considered a separate offense. If, after such notice, the premises continue to be used in a manner contrary to the provisions of Chapter
70, Zoning, or if any such owner or occupant shall fail to obey any law, or if any such owner or occupant shall fail to obey any lawful order of the Planning Administrator in respect to any violation or use contrary to the provisions of this chapter, the Planning Administrator shall institute appropriate legal proceedings to enforce the provisions of this chapter or to restrain by injunction any violation thereof, or both.
