40-8-5   NONCONFORMING USE OF LAND.
   Any lawful use of land existing on the effective date of this Code that would not be permitted under the terms of this Code may lawfully continue, subject to the following provisions:
   (A)   Intensification or Extension of Use. A nonconforming use of land shall not be intensified or extended to occupy a greater area of land than was occupied by such use on the effective date of this Code.
   (B)   Relocation. No nonconforming use of land shall be moved, in whole or in part, unless such use, upon relocation, will conform to all pertinent regulations of the district in which it is proposed to be located.
   (C)   Change of Use. Whenever a nonconforming use of a building has been changed to a more restrictive use or to a conforming use, such use shall not thereafter be changed to a less restrictive use. If no structural alterations are made, a nonconforming use of a building may be changed to another nonconforming use of the same or more restricted classification.
   (D)   Discontinuance. When a nonconforming use of land is discontinued for a period of twelve (12) consecutive months or for eighteen (18) months during any three (3) year period, it shall not thereafter be resumed, and any subsequent use of such land shall conform to the applicable district regulations. Any discontinuance caused by government action and without any contributing fault by the owner or operator shall not be counted in calculating the length of discontinuance.
