The material and construction of any sign and intermediary surface, and the manner of affixation of the sign to the intermediary -36- surface, and the intermediary surface to the wall of the building, shall be in accordance with any applicable provisions of the Building Code of the Town of Canton, and, otherwise, with the reasonable requirements of the Building Commissioner. All signs, together with their structural elements, shall be kept in good repair and in a proper state of preservation to the reasonable satisfaction of the Building Commissioner. The Building Commissioner may order the removal of any sign that is not maintained in accordance with the provisions of this By- law.
