Unless some other mode of abatement is approved by the building official or PCE Director in writing, abatement of nonconforming signs shall be accomplished in the following manner:

(c) Whenever a sign, other than those on public property or those deemed to be unsafe or abandoned, is found to be erected or maintained in violation of any provision of this chapter or of any other ordinance or law, the building official or PCE Director may order that such sign be altered, repaired, reconstructed, demolished or removed as may be appropriate to abate such condition. Any work required to be done shall, unless a different time is specified, be completed within ten days of the date of such order. Failure, neglect or refusal to comply with such order of the building official or PCE Director shall be sufficient basis for the revocation of any permit or approval granted under this chapter and shall constitute a separate offense. In addition to any other remedies provided by law, the building official may remove, or cause to be removed any such sign erected or maintained in violation of the provisions of this chapter.

(Ord. 5373 § 1 (part), 2016; Ord. 4305 § 1, 1995: Ord. 3559 § 1 (part), 1984)
