[Amended 3-24-2022 STM by Art. 14]
The Planning Board may authorize by special permit any extension, alteration or reconstruction of a nonconforming structure or to provide for its use for a substantially different purpose or for the same purpose in a substantially different manner or to a substantially greater extent, provided that no such extension, alteration, reconstruction or change in use shall be permitted unless the Planning Board finds that:
A.
For a change in use, the change, extension or alteration will not be substantially more detrimental than the existing nonconforming use to the neighborhood.
B.
The extended, altered or reconstructed structure will not be in greater nonconformity with open space, yard and off-street parking requirements of this chapter.
C.
The use or structure complies with other findings under § 199-13.4 that the Board deems relevant.
