(a) A legal nonconforming structure shall not be modified in a manner that expands, extends, or enlarges the use in any manner beyond its existing scope upon the effective date of this zoning ordinance, except as follows:
(1) The modifications are, in and of themselves, in conformance with the provisions of this title.
(2) The modifications are limited to minor alterations, improvements, or repairs that do not increase the degree of nonconformity present and do not constitute or tend to produce an expansion or intensification of a nonconforming use.
(3) The modifications are required by other laws.
(4) The modifications are incidental to the public acquisition of a portion of a site, no greater degree of nonconformity will be created other than that caused as a result of the public acquisition, and the changed development will conform to current regulations to the maximum extent feasible.
(b) No change made to any development or use shall be construed as automatically permitting an extension of any time limit for the termination of a nonconformity.
(Ord. 612 Exhibit A (part), 2008).
