If a nonconforming use is discontinued or terminated for a period
of 12 months, any further use of the structure, land or water shall
conform to the provisions of this chapter.
Additions and enlargements to existing nonconforming structures
with a conforming use are permitted and shall conform to the established
yard/setback, height, parking, loading, and access provisions of this
chapter. Existing buildings and their additions shall not be permitted
to encroach further upon established yard/setback and height requirements
than the existing encroachment. The provisions of this section with
respect to additions or enlargements are applicable only if the lot
is served by public sanitary sewer or, if relevant, conforms to existing
sanitary code requirements for private on-site sewage treatment systems
(POWTS).
In any district, any permitted or permissible structure may
be erected on a single lot of record at the effect date of adoption
or amendment of this chapter. This provision shall apply even though
such lot fails to meet the requirements of lot area, lot width, or
both, for the district in which the lot is located, as amended, as
long as the lot lawfully existed at the time of the adoption of or
amendment to this chapter.
Once a nonconforming use or structure has been changed to conform,
it shall not revert back to a nonconforming use or structure. Once
the Zoning Board of Appeals has permitted the substitution of a more
restrictive nonconforming use for an existing nonconforming use, the
substituted use shall lose its status as a legal nonconforming use
and become subject to all the conditions required by the Zoning Board
of Appeals.
