If a lawful use involving individual structures, or of a structure and premises in combination, exists at the effective date of adoption or amendment of this Zoning Code that would not be allowed in the district under the terms of this Zoning Code, 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 Zoning Code 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 conforming use may be extended throughout any parts of a building which were manifestly arranged or designed for such use at the time of adoption or amendment of this Zoning Code, but no such use shall be extended to occupy any land outside such building;
(c) In no structural alterations are made, any nonconforming use of a structure or structure and premises may, as a conditional use, be changed to another nonconforming use provided that the Planning Commission finds that the proposed use is equally appropriate or more appropriate to the district than the existing nonconforming use. In permitting such change, the Planning Commission may require appropriate conditions and safeguards in accordance with other provisions of this Zoning Code.
(d) Any structure, or structure and land in combination, in or on which a conforming use is superseded by a permitted use, shall thereafter conform to the regulations for the district, and the nonconforming use may not thereafter be resumed;
(e) Where there is a nonconforming use status applied to a structure and premises in combination, removal or destruction of the structure shall eliminate the nonconforming status of the land.
