If lawful use involving individual structures with a current replacement cost of $1,000 or more, or of structure and premises in combination, exists at the effective date of adoption of this chapter that would not be allowed in the district under the terms of this chapter, 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 chapter 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; or unless granted permission by the Board of Appeals on Zoning by the authority provided under § 153.584(F) and in accordance with the following requirements:
(1) Any enlarged portion shall conform to the yard and height requirements for the district in which it is located and be situated on land which was under the same ownership as that occupied by the existing building or structure on October 15, 1958, and has continued to be in one ownership;
(2) The total floor area added to any nonconforming use shall never exceed 50% of the floor area occupied by such use on October 15, 1958, and any extension granted shall be entirely within an enclosed building; and
(3) Any Board of Appeals on Zoning action taken in connection with the enlargement of a nonconforming use or building shall conform with the general standards outline in § 153.589.
(B) Any nonconforming use may be extended throughout any parts of a building which were manifestly arranged or designed for such use at the time of adoption of this chapter, but no such use shall be extended to occupy any land outside such building.
(C) If no structural alterations are made, any nonconforming use of a structure, or structure and premises, may be changed to another nonconforming use provided that the proposed use is equally appropriate or more appropriate to the district than the existing nonconforming use. Whenever a nonconforming use has been changed to a conforming use, or to a use permitted in a district of greater restrictions, it shall not thereafter be changed to a nonconforming use.
(D) Where nonconforming use status applies to a structure and premises in combination, removal or destruction of the entire structure shall eliminate the nonconforming status of land.
