1147.02 NONCONFORMING USES, BUILDINGS.

   (a)    A nonconforming use existing at the time such use became nonconforming may be continued. A nonconforming use shall not be extended except as authorized by Section 1147.01, but the extension of a use to any portion of a building, which portion was arranged or designed for such nonconforming use at the time such use became nonconforming shall not be deemed the extension of a nonconforming use.

   A nonconforming use may not be changed unless changed to a more restricted use. A nonconforming use, if changed to a conforming use, may not thereafter be changed back to any nonconforming use. A nonconforming use, if changed to a more restricted nonconforming use, may not thereafter be changed unless to a still more restricted use. For the purpose of this Zoning Code, a more restricted use is a use appearing in a prior or preceding classification of uses as set forth in Sections 1141.02 to 1141.08, inclusive, of this Zoning Code.

   (b)    It shall not be unlawful for the owner of any residential dwelling which is nonconforming by reason of a set back or side yard distance at the time of the passage of this section, to extend, enlarge or add to said nonconforming dwelling if the Building Commissioner determines that the extension, enlargement or addition would not result in any additional violation of the Codified Ordinances. This subsection shall apply only to single family residential dwellings and not to any accessory, utility or garage structure or building. (Ord. 1994-45. Passed 12-13-94.)
