If a lawful use of a structure or of structures and premises in combination exists at the effective date of adoption or amendment of this title that would not be allowed in the district under the terms of this title, the lawful use may be continued so long as it remains otherwise lawful, subject to the following provisions:
(A) No existing structure devoted to a use not permitted by this title in the district in which it is located shall be enlarged, extended, constructed, reconstructed, moved or structurally altered except in changing the use of the structure to a use permitted in the district in which it is located.
(B) Any nonconforming use may be extended throughout any part of a building which was manifestly arranged or designed for such use at the time of adoption or amendment of the title, but no such use shall be extended to occupy any land outside such building. (Ord. 1576, 5-1-1989, eff. 6-15-1989)
(C) If no structural alterations are made, any nonconforming use of a structure or land may be changed to another nonconforming use; provided, that the city commission issues a conditional use permit. In determining whether or not to grant the conditional use permit, the city commission shall find that the proposed use is equally or more appropriate to the district than the existing nonconforming use. In permitting such change, the city commission may require appropriate conditions and safeguards in accordance with the provisions of this title. (Ord. 1576, 5-1-1989, eff. 6-15-1989; amd. Ord. 1664, 1-3-2000)
(D) Any structure or structures and land in combination in or on which a nonconforming use is superseded by a permitted use shall thereafter conform to the regulations for the district in which such structure is located and the nonconforming use may not be thereafter resumed.
(E) When a nonconforming use of a structure or structures and land in combination is discontinued for eighteen (18) months, any subsequent nonconforming use of the structure or structures and land in combination shall be reviewed by the board of adjustment as to whether said structure should conform with the regulations of the district in which it is located.
(F) Where nonconformity use status applies to a structure and land in combination, removal or destruction of the structure shall eliminate the nonconforming status of the land. "Destruction" for the purpose of this subsection is defined as damage to an extent of eighty percent (80%) of the replacement cost at time of destruction. (Ord. 1576, 5-1-1989, eff. 6-15-1989)
