A nonconforming use, building or structure may not be enlarged, extended or structurally altered in any manner unless the nonconforming use, building or structure after so enlarged, extended or altered is made to conform to all the regulations of the district in which it is located or unless a special permit is issued therefore pursuant to § 162.030. Whether a change to a nonconforming use, building or structure is to be considered an enlargement, extension or structural alteration of a nonconforming use is to be liberally construed in favor of a conclusion that the change is an enlargement, extension or structural alteration, it being the purpose and intent hereof that all nonconforming uses shall be eventually eliminated or strictly regulated. Notwithstanding anything herein to the contrary, normal maintenance of a building or structure containing a nonconforming use or being nonconforming is permitted provided there are not enlargements, extensions or structural alterations.
