A. If within the districts established by this title or amendments that may later be adopted there exist lots, structures, and use of land and structures which were lawful before this title was passed or amended, but which would be prohibited, regulated, or restricted under the terms of this title or future amendments, it is the intent of this title to permit these nonconformities to continue until they are removed, but not to encourage their survival. Such uses are declared by this title to be incompatible with permitted uses in the districts involved.
B. It is further the intent of this title that nonconformities shall not be enlarged upon, expanded or extended, nor be used as grounds for adding other structures, signs or uses prohibited elsewhere in the same district.
C. To avoid undue hardship, nothing in this title shall be deemed to require a change in the plans, construction, or designated use of any building on which actual construction was lawfully begun prior to the effective date of adoption or amendment of this title and upon which actual building construction has been diligently carried on. "Actual construction" is hereby defined to include the placing of construction materials in permanent position and fastened in a permanent manner; except that the demolition or removal of an existing building has been substantially begun preparatory to rebuilding, such demolition or removal shall be deemed to be actual construction; provided, that work shall be diligently carried on until completion of the building involved.
