Subject to the provisions of this section a use of a building or structure or land, existing at the time of enactment of this Zoning Ordinance, may be continued even though such use does not conform with the provisions of this Zoning Ordinance hereinbefore set forth, provided, however, that no enlargement or expansion thereof shall be permitted except on Resolution passed by a majority vote of Council after a recommendation concerning such enlargement or expansion has been submitted to Council by the Planning Commission. Nothing in this Zoning Ordinance shall prevent the reconstruction or replacement of a building wholly or partially destroyed by fire, explosion, act of God, act of the public enemy, or wholly or partially declared unsafe or condemned because of safety or health reasons; provided, however, that the same has not been abandoned with respect to such nonconforming use; and provided further, however, that such new or repaired buildings shall not contain more than ten percent (10%) more than the original floor space of the replaced building, and such new building or repair, shall be used for no nonconforming use other than that for which the replaced building was used. Such nonconforming uses are to be listed by the Planning Commission as of the effective date of this Zoning Ordinance. A nonconforming use of a building or land which has been abandoned shall not thereafter be returned to such nonconforming use. A nonconforming use shall be considered abandoned as follows: when abandoned for a period of two years as specified in the Laws of Ohio, or when such nonconforming use has been replaced by conforming use.
