(a) Within the districts established by this Zoning Ordinance or amendments that may later be adopted there exists lots, structures, uses of land and structures, and characteristics of use 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 or future amendments. It is the intent of this Zoning Ordinance to permit those nonconformities to continue until they are removed, but not to encourage their survival.
(b) It is further the intent of this Zoning Ordinance that nonconformities shall not be enlarged upon, expanded or extended, rebuilt after near total destruction, nor be used as grounds for adding other structures or uses prohibited elsewhere in the same district, except as hereby provided in Chapter 1181
