Except as provided in this section, uses and structures made nonconforming as a result
of a rezoning of property to NC, NAC or NR are subject to the provisions of article
III of Chapter 38.
Destruction of nonconforming signs and the ability to rebuild such signs shall be
subject to the nonconforming use provisions of section 38-53 (b). Nonconforming signage, excluding billboards, on properties that are vacant for
one hundred eighty (180) days or more, as determined by a vacant structure on the
property and sign face copy that is blank or does not advertise current business activity
for that period, shall lose its nonconforming status. A vacant building shall be the
primary factor for determining the expiration of nonconforming status of a sign. This
subsection shall apply to single tenant structures and to multi-tenant structures
where the entire multi-tenant structure is vacant. Upon occupancy of the structure
by a business, signage that has lost its nonconforming status must come into compliance
with this article. Any new signage on the property must be consistent with the signage
requirements of this article.
