[Amended 4-11-2006 by Ord. No. 2006-11]
The 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.
Normal maintenance is permitted. Any extension or enlargement of a
nonconforming structure is subject to review and approval of the City
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 Board of Zoning 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 Board of
Zoning Appeals.
