Change of use

A nonconforming use shall not be changed to another nonconforming use, but may be changed only to a use that conforms to the regulations of the district in which it is located, unless a special use permit is obtained pursuant to Article XIV hereof. In addition, the Zoning Board of Review must made a determination that the proposed use will have the same or a lesser undesirable impact upon the surrounding area than the former nonconforming use. When a nonconforming use is changed to a conforming use, it may not thereafter be changed back to a nonconforming use.
