A. A nonconforming use of a structure, a nonconforming use of land or a nonconforming use of a structure and land shall not be extended or enlarged after the provisions of this title or its amendments became applicable to such land, structure or use. Among other things, the attachment on a building or premises of additional signs intended to be seen from off the premises or the addition of other uses constitutes such an extension or enlargement.

B. To avoid undue hardship, nothing in this title shall be deemed to require a change in the plans, construction or designated use of any building on which actual construction was lawfully begun before the provisions of this title or its amendments became applicable to such building and upon which actual building construction has been diligently carried on. “Actual construction” is defined to include the placing of construction materials in permanent position and fastened in a permanent manner. In addition, where demolition or removal of an existing building has been substantially begun in preparation of rebuilding, such demolition or removal shall be deemed to be actual construction; provided, that work shall be diligently carried on until completion of the building involved. In no event shall the time of such construction exceed a period of one year except for a demonstrated cause approved in writing by the commission. (Ord. 609 § 5, 2004)
