No nonconforming use shall be enlarged, extended, reconstructed, or structurally altered, except as follows:
(a) The Board of Zoning Appeals may permit, on a once-only basis, a building containing a nonconforming use to be enlarged to an extent so the resulting building shall be not more than one-hundred-seventy-five percent (175%) of the ground floor area of the existing building or structure devoted to a nonconforming use at the time of enactment of this Ordinance. The Commission shall not authorize an enlargement, which would result in a violation of the provisions of this Ordinance with respect to a yard or setback affecting any adjoining premises.
(b) No nonconforming building or structure shall be moved in whole or in part to any other location unless such building or structure and the yard and other open spaces provided are made to conform to all of the regulations of the district in which such building or structure is to be located.
(c) Any residential structure that is nonconforming due to the fact of its being in a non- residential zoning district may be enlarged, extended, reconstructed or structurally altered, provided it meets the requirements of the most proximate Residential District. (Ord. 07-8. Passed 3-19-07.)
