If the Building Commissioner shall be informed or have reason to believe that any provision of this bylaw or of any permit or decree thereunder has been, is being, or is likely to be violated, he shall make or cause an investigation to be made of the facts, including an inspection of the property where the violation may exist, and if he finds any violation, he shall give immediate notice, in writing, to the owner or his duly authorized agent and to the occupant of the premises and shall order that any violation of the provisions of this bylaw shall immediately cease. If, after such notice and order, such violation continues, or if any owner, agent or occupant fails to obey any lawful order of the Building Commissioner with respect to any violation or any use contrary to the provisions of this bylaw, the Building Commissioner shall forthwith revoke any permit issued for the occupation of the premises, may make complaint to the Superior Court or any court of competent jurisdiction for an injunction or order restraining the further use of the premises, and shall take such other action as is necessary to enforce the provisions of this bylaw. In the event the Building Commissioner is requested, in writing, to enforce the Zoning Bylaw and he declines to do so, he shall notify, in writing, the party requesting such enforcement of any action or refusal to act and the reasons therefor within 14 days of receipt of the request.
