Change of use
a. A nonconforming residential use may change only to a use that conforms to the provisions of this ordinance.
b. A nonconforming agricultural, commercial or industrial use may be changed only to a use that conforms to the provisions of this ordinance unless one of the following occurs:
(1) A special use permit is issued by the zoning board of review under the provisions of article XVI, for a change to a similar nonconforming use; or
(2) A use variance is granted by the zoning board of review under the provisions of article XVII, for a change to any other nonconforming use.
In all cases, the zoning board of review must make a determination that the proposed use will have the same or a lesser undesirable impact upon the surrounding area than the former nonconforming use.
c. When a nonconforming use is changed to a conforming use, it may not thereafter be changed back to a nonconforming use.
