[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.
