(A) If a nonconforming use exists on the effective date of this chapter that would be allowed under the terms of this chapter, the nonconforming use may be continued so long as it remains otherwise lawful, subject to the following provisions:
(1) A nonconforming use may be changed to a conforming use. Thereafter the property may not revert to a nonconforming use.
(2) A nonconforming use may be changed to another nonconforming use only in accordance with a nonconformity permit issued by the Board of Zoning Adjustment. The Board shall issue such permit if it finds that the proposed use will be in the same or more restricted use classification.
(B) If a nonconforming use and conforming use, or any combination of conforming and nonconforming uses, or any combination of nonconforming uses exist on one lot, the use made of the property may be changed substantially (except to a conforming use) only in accordance with a nonconformity permit issued by the Board of Zoning Adjustment. The Board shall issue such a permit if it finds that the proposed use will be in the same or more restricted use classification.
