Investigation. If the Inspector of Buildings shall be informed, or have reason to believe, that any provision of these Bylaws or any permit or decision thereunder has been, is being, or is about to be violated, he shall make or cause to be made an investigation of the facts, including the inspection of the premises where the violations may exist. The Inspector of Buildings shall take action upon written complaint and shall report such action or refusal to act, and the reasons therefore, in writing to the complainant within fourteen days of receipt thereof.
