Within the districts established by this Zoning Ordinance, or by amendments thereto, lots, uses of land, structures, and uses of structures and land in combination exist which were lawful before this Zoning Ordinance was passed or amended, but which would be prohibited, regulated, or restricted under the terms of this Zoning Ordinance. The legitimate interest of those who lawfully established these nonconformities are herein recognized by providing for their continuance, subject to regulations limiting their completion, restoration, reconstruction, extension, and substitution. Nevertheless, while it is the intent of this Zoning Ordinance that legal nonconformities be allowed to continue until removed, they should not be encouraged to survive. Therefore, no nonconformity may be moved, extended, altered, expanded, or used as grounds
for any other use(s) or structure(s) prohibited elsewhere in the district except as otherwise specifically provided for in this Zoning Ordinance.
