If, at the time of enactment or amendment of
this chapter, any lot, building or structure is being used in a manner
or for a purpose which does not conform to the provisions of this
chapter and which is not prohibited by some other ordinance, such
manner of use or purpose may be continued, and any renewal or change
of title of possession, or right to possession, or lease of any such
lot, building or structure shall not be construed to prevent the continued
nonconforming use of such lot, building or structure, as herein provided.
A. Any such nonconforming use which is not otherwise
unlawful may be hereafter extended throughout any part of a building
or structure, if indoors, or lot, if outdoors, which was manifestly
arranged or designed for such use at the time of enactment or amendment
of this chapter, provided that the yard, setback and height regulations
of the district in which the use is located are observed. No building
or structure containing a nonconforming use shall be hereafter extended
or enlarged except in conformance with the provisions of this chapter.
B. No building or structure in which active nonconforming
use is discontinued for a period exceeding two years subsequent to
the enactment or amendment of this chapter shall again be devoted
to any prohibited use.
C. Whenever a nonconforming use of a building has been
changed to a more restricted use or to a conforming use, such use
shall not thereafter be changed to a less restricted use, unless such
use would conform to zoning for the area.
