(A) Any lawful use of a building existing at the effective date of this chapter may be continued, even though such use does not conform to the provisions hereof. If no structural alterations are made, a nonconforming use of a building may be changed to another nonconforming use of the same or of a more restricted classification. Whenever a nonconforming use has been changed to a more restricted use or to a conforming use, such use shall not thereafter be changed to a less restricted use. The nonconforming use of a building may be extended throughout those parts thereof which were manifestly arranged or designed for such use at the time of adoption of this chapter.
(B) Whenever the use of a building shall become nonconforming through a change in the zoning regulations or in the district boundaries such use may be continued, and if no structural alterations are made, may be changed to another nonconforming use of the same or of a more restricted classification.
(C) Whenever a nonconforming use of a building or portion thereof is discontinued for a continuous period of 2 years, any future use of such building or portion thereof shall be in conformity with the regulations of the district in which the building is located.
(D) A nonconforming building which has been damaged by fire, explosion, act of God or the public enemy to the extent of more than 75% of its reproduction value at the time of damage shall not be restored except in conformity with the regulations of the district in which it is located or as provided in §§ 153.123. When damaged by less than 75% of its reproduction value, a nonconforming building may be repaired or reconstructed and used as before the time of damage provided such repairs or reconstruction are completed within 1 year of the date of such damage.
(E) A nonconforming use in violation of the provisions of the zoning regulations which this chapter supersedes shall not be validated by the adoption of this chapter.
