When old uses of land or buildings can continue

A nonconforming use of land, buildings, or other structures may continue to the extent that the use existed on September 1, 1972 or any amendment hereto, as provided in this Section, provided that the Planning Commission may, after hearing, order the termination of a nonconforming use that creates substantial danger to public health or safety.If any nonconforming use ceases for any reason for continuous period of 12 calendar months or for one season if the use be seasonal, then the use shall not be resumed and any use of the land or building thereafter shall be in full conformity with the provisions of this Chapter.If the nonconforming use is carried on in a nonconforming building or structure and the portion of the building or structure within which nonconforming use is conducted is destroyed or damaged, the use may be resumed if restoration or reconstruction, as permitted by this Article, is completed within one year from the date of the damage or destruction. If the building or structure may not be restored or reconstructed under the provisions of this Chapter, or if the building or structure was conforming, the nonconforming use may not be resumed and any use of the land or building thereafter shall be in full conformity with the provisions of this Chapter.Any building lawfully in existence and vacant prior to or on September 1, 1972 may within six months thereafter, be occupied by the use for which it was manifestly designed or arranged.
