A. 
Whenever a nonconforming use has been changed to a conforming use, such use shall not thereafter be changed to a nonconforming use.
B. 
Whenever a nonconforming use has been changed to a more restricted classification or to a conforming use, such use shall not hereafter be changed to a use of less restricted classification unless in compliance with the rules for such change as outlined by this article.
C. 
A nonconforming use may be changed to another nonconforming use only by the granting of a special exception by the Zoning Hearing Board in compliance with this chapter.

Such nonconforming use shall not thereafter be reinstated except in conformance with this chapter.

The applicant shall be responsible to provide evidence that the nonconformity was not abandoned.
B. 
Except for in a mobile home park, the removal of a nonconforming mobile home from the site it occupied (and if such site is not leased, actively marketed, or purchased within one year or less) shall constitute abandonment of the site, and any occupation or subsequent use of said site shall conform with the provisions of this chapter.
C. 
The removal of a mobile home from a residential lot already occupied by a residential building shall constitute abandonment of the nonconforming use and such use shall not thereafter be permitted. (Exception: Mobile homes utilized for temporary housing for farm employees.)
