If the Building Official shall find that any sign or other advertising structure regulated hereunder is unsafe or not securely fastened or is a menace to the public, or has been constructed or erected or is being maintained in violation of the provisions of this chapter, the Building Official shall give written notice thereof to the permit holder. Such notice shall include a statement explaining the alleged violations and deficiencies, an order to repair or remove said sign, and an explanation of the consequences of failure to comply with said order. If the permit holder fails to remove or alter said sign so as to comply with the order within ten days after such notice, said sign or other advertising structure may be removed or altered to comply by the Building Official at the expense of the permit holder or owner of the property on which it is located. The permit holder may appeal the order of the Building Official to the Council, and, if such an appeal is on file, the ten-day compliance period shall be extended until ten days following the Council’s decision on the matter. If, however, the Building Official finds that any sign or other advertising structure poses a serious and immediate threat to the health or safety of any person, the Building Official may order the removal of such sign summarily and without notice to the permit holder. Such an order may be appealed to the Council, and if the Council reverses, it shall order restitution at the City’s expense.
