§ 153.143  NONCONFORMING SIGNS.
   (A)   All existing on-premises freestanding signs that exceed the maximum sign face size, sign height, maximum number of signs or spacing requirements of this chapter shall be brought into compliance with the requirements of this chapter or removed entirely, which means the entire sign and any associated equipment, within ten years of this effective date of this chapter.
   (B)   When two or more signs are made nonconforming because of not adhering to spacing requirements, the age of permit shall determine which sign shall be removed; the sign with the oldest valid permit shall be permitted to stay.
   (C)   Signs not permitted in a zoning district:
      (1)   Advertising signs within the city extraterritorial jurisdiction shall be allowed to continue as nonresidential nonconforming structures as described in § 153.137 of this chapter.
      (2)   If a sign is not permitted use, but is an identification sign for a lawful nonconforming use, the sign may be used for as long as the nonconforming use is allowed to continue; except that the sign, within ten years following the effective date of this chapter or the date the use became nonconforming due to some later amendment to this chapter, shall at a minimum meet all the requirements for the sign as specified for the next descending zone (§ 153.315(G)) permitting the use.
   (D)   All other nonconforming signs not provided for otherwise in this section and prohibited by § 153.167 of this chapter shall be removed entirely or otherwise brought into conformance with this chapter, whichever is applicable, within six months of the effective date of this chapter, except that portable signs shall be removed entirely or otherwise brought into conformance with this chapter, whichever is applicable, within one year of the effective date of this chapter.
