(a) Substitution: When authorized by the Planning Commission, the substitution of a non-conforming use for another less objectionable non-conforming use.
(b) Non-Conforming Use Made to Conform: Whenever a non-conforming use has been changed to a conforming use, such use shall not thereafter be changed to a non-conforming use.
(c) Expansion: The Planning Commission shall have the authority to grant an expansion or permit completion of a building devoted to a non-conforming use upon a lot occupied by such building or on a lot adjoining and where such extension is necessary and incidental to the existing use of such building provided, however, that the floor areas of such extension shall not exceed in all one hundred percent (100%) of the floor area of the existing building or buildings devoted to a non-conforming use.
