The North Andover Zoning Bylaw shall be enforced by the North Andover Building Inspector. The Building Inspector, upon being informed in writing of a possible violation of this bylaw or on his own initiative, shall make or cause to be made an investigation of facts and an inspection of the premises where such violation may exist. If the Building Inspector is so informed in writing and declines to act, he/she shall, within 14 days of his receipt of such information, give to his informant, in writing, his reasons for refraining from taking any action. The Building Inspector, on evidence of any violation after investigation and inspection, shall give written notice of such violation to the owner and to the occupant of such premises, and the Building Inspector shall demand in such notice that such violation be abated within such reasonable time as may be given by mail addressed to the owner at the address appearing for him/her on the most recent real estate tax records of North Andover, and to the occupant at the address of the premises of such seeming violation. If, after such notice and demand, such violation has not been abated within the time specified, the Building Inspector or the Selectmen shall institute appropriate action or proceedings in the name of the Town of North Andover to prevent, correct, restrain, or abate any violation of this bylaw.
