The following provisions shall apply to all buildings and uses
existing on the effective date of this chapter which do not conform
to the requirements set forth in this chapter and to all buildings
and uses that become nonconforming by reason of any subsequent amendment
to this chapter:
A. Any nonconforming use of buildings or open land may be continued,
except that the same shall not be:
(1) Enlarged, altered, extended, reconstructed or restored, except as provided in Subsection
A(5), or placed on a different portion of the lot or parcel of land occupied by such use on the effective date of this chapter, nor shall any external evidence of such use be increased by any means whatsoever.
(2) Moved to another location where such use would be nonconforming.
(3) Changed to another nonconforming use without approval by the Board
of Appeals, and then only to a use which, in the opinion of the Board
of Appeals, is of the same or of a more restricted nature.
(4) Reestablished if such use has been discontinued for any reason for
a period of one year or more or has been changed to or replaced by
a conforming use. Intent to resume a nonconforming use shall not confer
the right to do so.
(5) Restored for other than a conforming use after damage for any reason
exceeding 75% of its assessed value or its bulk. If the restoration
of a building whose damage does not exceed 75% of its assessed value
or its bulk is not completed within a one-year period, the nonconforming
use of such building shall be deemed to have been discontinued.
Nothing in this article shall be deemed to prevent normal maintenance
and repair, structural alteration in or the reconstruction or enlargement
of a noncomplying building, provided that such action does not increase
the degree of or create any new nonconformity or noncompliance with
regard to the regulations pertaining to such buildings.
