Any lawful use of the land which exists prior to the date of adoption of the Development Code but which would not be permitted under the terms of this Code may lawfully continue; provided that, the nonconforming use of the land shall not be:
(A) Intensified or extended to occupy a greater area of land than already occupied;
(B) Moved, in whole or in part, unless the use, upon relocation, will conform to all the regulations of the zoning district in which it is located;
(C) Changed, except to a permitted use; and
(D) Discontinued longer than 12 consecutive months, or it shall not thereafter be allowed to resume; any discontinuance caused by government action and without any contributing fault by the nonconforming user shall not be counted in calculating the length of discontinuance.
