A. The owner of any sign as defined and regulated by this title, including supporting structures, shall keep the same in a safe condition at all times.

B. If the planning commission shall find that any sign regulated herein is unsafe or insecure, or is a menace to the public, they shall give written notice to the sign owner and to the property owner. If such sign owner fails to remove or alter the sign so as to comply with the standards herein set forth within thirty days after such notice, the planning commission may cause such sign to be removed or altered to comply at the expense of the sign owner or owner of the property upon which it is located. The planning commission may cause any sign which is an immediate danger to persons or property to be removed summarily and without notice. (Ord. 89-3 (part), 1989)
