(B) No structure partially occupied by a non-conforming use shall be moved, altered or enlarged in such a way as to permit the enlargement of the space occupied by the non-conforming use.
(C) No non-conforming use shall be enlarged or extended in such a way as to occupy any part of the structure or site or another structure or site which it did not occupy on the effective date of the ordinance codified in this title or of the amendment thereto which caused it to become a non-conforming use, or in a way as to displace any conforming use occupying a structure or site.
