Within the zones established by this title, or amendments thereto, there exist lots, structures, and uses of land and structures which were lawful before this title was enacted or amended by ordinance, but which would be prohibited, regulated, or restricted under the terms of this title or amendments thereto. Such uses are generally considered to be incompatible with the permitted uses in the zone in which they are located, and their continuance shall therefore be permitted only in strict compliance with the restrictions of this chapter. However, existing single-family residential uses shall not be treated as nonconforming uses, unless such use is voluntarily discontinued. Subject to the provisions of this chapter, a nonconforming structure or use may be continued and maintained in reasonable repair, but shall not be altered or extended except as provided herein. The extension of a nonconforming use to a portion of a structure, which was arranged or designed for the nonconforming use at the time of passage of the ordinance codified in this title, is not considered an enlargement or expansion of a nonconforming use.

A use or structure which, on the date the ordinance codified in this chapter takes effect and Ordinance Number 146 and amendments thereto are repealed, violates that ordinance as it then reads shall not be regarded as nonconforming but shall remain in violation under this title. [Ord. 817 § 8-3M.210, 2006.]
