Nonconforming signs are hereby declared a nuisance. The provisions of the article
on Nonconformities at Section 153.390 et seq. shall apply to all existing exterior signs rendered nonconforming by the
provisions of this chapter, provided, however, that no exterior sign may be enlarged,
reconstructed, altered to identify a different business, owner, tenant, operator,
agent, or use, or structurally altered unless conforming to the provisions of this
chapter and any other applicable sections of this Zoning Code. The Board of Zoning
Appeals shall not permit the replacement, installation, enlargement, reconstruction,
or alteration of any exterior sign unless it conforms to the provisions of this chapter.
Minor repair, cleaning, or change of copy for the same business or use, however, shall
be permitted regardless of the conforming or nonconforming status of the exterior
sign. Penalty, see § 153.199.
