(A) This chapter or any later amendments may create situations where structures, buildings or uses of the land previously permitted may become prohibited, regulated or otherwise restricted. It is the intent of this chapter to permit the continuance of these non-conforming structures or uses until they are removed, but not to encourage their survival.
(B) These uses are declared by this chapter to be incompatible with the permitted uses in the districts involved:
(1) Any existing building or premises devoted to a use not permitted by this chapter in the district in which the building or premises is located, shall not be enlarged upon, extended, reconstructed or structurally altered, nor be used as grounds for adding other buildings or structures prohibited elsewhere in the same district, except when required to do so by law or ordinance, unless the use is changed to one permitted in the district in which the building or structure or land is located;
(2) A non-conforming use of a building may be replaced with another non-conforming use; provided, no structural alterations are made;
(3) No change from one non-conforming use to another shall be made without first applying to and receiving from the Planning Commission a permit to make the change;
(4) A non-conforming use may be changed to a more conforming use at any time;
(5) Whenever a non-conforming use has been changed to a conforming use, the use shall not thereafter be changed to a less conforming use;
(6) The extension or addition of a lawful use to any portion of a non-conforming building or structure or land shall not be deemed as the extension of the non-conforming use;
(7) Where non-conforming status applies to a building or structure, the removal or destruction of the same shall eliminate the non-conforming status of land;
(8) If a building or structure is moved for any reason for any distance whatever, it shall thereafter conform to the regulations for the district in which it is located after it is moved;
(9) All uses which lawfully exist on the effective date of this chapter and are classified as a conditional use by this chapter for the district in which they are located, shall be considered lawful conditional uses; and
(10) Whenever the boundaries of a district shall be changed so as to transfer an area from one district to another district of a different classification, the provisions of this subchapter shall also apply to any non-conforming uses developing as a result of the action.
