[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. II)]
A lawful nonconforming structure existing at the time of the
adoption or amendment of this chapter may be continued although its
size or location does not conform with the lot width, lot area, yard,
height, parking and loading, and access provisions of this chapter.
However, it shall not be extended, enlarged, reconstructed, moved
or structurally altered except when required to do so by law or order
or so as to comply with the provisions of this chapter. Any extension
or enlargement of a nonconforming structure is subject to review and
approval of the Plan Commission. This provision shall not be interpreted
to disallow the extension or enlargement of a structure in respect
to those dimensions that are in conformance with this chapter so long
as additional nonconformities are not created thereby.
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.
