A.
The provisions of this chapter shall regulate the continuation, termination, and modification of developments and uses which were lawfully established but which no longer conform to the provisions of this Title due to changes in such provisions. A mere change in ownership or tenancy without any change in use, occupancy, or development shall not affect any of the nonconforming rights, privileges, and responsibilities provided under this chapter.
B.
Any nonconforming situation which becomes specifically authorized under the terms of some approval pursuant to this Title, other than approval of an extension, expansion, change, or early termination of nonconforming pursuant to Section 19.132.020, shall thenceforth be governed by the terms of such approval and shall no longer be considered to be a nonconformity unless and until such approval expires or is revoked.
