(A) Within the districts established by this Zoning Code, or amendments that may later be adopted, there exist lands and land usages which were lawful before this Zoning Code was passed or amended, but which would be prohibited, regulated, or restricted under the terms of this Zoning Code or future amendment, including certain:
(1) Lots,
(2) Structures,
(3) Uses of land and structures.
(B) It is the intent of this Zoning Code to permit these nonconformities to continue until they are removed, but not to encourage their survival. It is further the intent of this Zoning Code that nonconformities shall not be used as grounds for adding other structures or uses prohibited elsewhere in the same district.
(C) Nonconforming uses are declared by this Zoning Code to be incompatible with the permitted uses in the districts involved. A nonconforming set-back of a structure shall not be decreased and a nonconforming use of land or structure shall not be changed after passage of this Zoning Code by the addition of other uses of a nature which would be prohibited generally in the district involved.
