(A)   The lawful use of a building or premises existing on 5-27-1957 may be continued although the use does not conform to all the provisions of this chapter, except as hereinafter provided.
      (1)   A non-conforming use may be extended throughout a building; provided, no structural alterations other than those required by law are made therein.
      (2)   A non-conforming use may be changed to another non-conforming use of the same or greater restrictions; provided, no structural changes are made in the building. Whenever a non-conforming use has been changed to a conforming use or to a use permitted in a district of greater restrictions, it shall not thereafter be changed to a non-conforming use of a less restricted one.
      (3)   No building shall be erected upon any premises devoted to a non-conforming use, and no building located upon such premises which has been damaged by fire or other causes to the extent of more than 75% of its appraised valuation shall be repaired or rebuilt, except in conformity with the regulations of this chapter.
      (4)   The Board of Zoning Appeals may authorize by written permit, in a residence district for a period of not more than one year from the date of the permit, a temporary building for commercial or industrial use incidental to the residential construction and development of the district.
      (5)   In the event that a non-conforming use of any building or premises is discontinued for a period of two years, the use of the building or premises shall thereafter conform to the uses permitted in the district in which it is located.
      (6)   The use of land for storage purposes which may become a non-conforming use by reason of an amendment to this chapter, shall be discontinued within five years from the date of passage of the amendment.
   (B)   These provisions apply in the same manner to a use which may become a non-conforming use due to a later amendment to this chapter.
