A nonconforming use existing at the time of the passage of this Zoning Code (Ordinance 46-68, passed February 3, 1969), or amendments thereto, may be continued, provided that if said nonconforming use is wholly or substantially discontinued for a period of six months or more from the date that it became a nonconforming use, it shall be deemed to have been abandoned and thereby extinguished. A nonconforming use shall not be extended except as authorized, 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 of the passage of this Zoning Code shall not be deemed the extension of a nonconforming use. A building arranged, designed or devoted to a nonconforming use at the time of the passage of this Zoning Code shall not be reconstructed or structurally altered to an extent exceeding in aggregate cost, during any ten-year period, 50% of the fair market value of the land and building, unless the use of such building is changed to a conforming use. A nonconforming use, if changed to a conforming use, may not thereafter be changed back to a nonconforming use.
