§ 152.178  NONCONFORMING USES OCCUPYING A STRUCTURE.
   If any lawful use occupying a structure exists on the effective date of this chapter but would not be allowed under the terms of this chapter, such use may lawfully continue, subject to the following provisions:
   (A)   Maintenance.  Any structure housing a nonconforming use may be maintained through ordinary repairs.
   (B)   Enlargement, alteration, reconstruction, relocation.  No structure housing a nonconforming use shall be enlarged, structurally altered, reconstructed or relocated unless 50% of the structure is changed to a permitted use.
   (C)   Extension of use.  No nonconforming use may be extended to any part(s) of the structure not intended or designed for such use, nor shall the nonconforming use be extended to occupy any land outside such structure.
   (D)   Change of use.  A nonconforming use occupying a structure may be changed to a similar use, to a more restrictive use, or to a conforming use.  Such use shall not thereafter be changed to a less restrictive use.
   (E)   Discontinuance of use.  When a nonconforming use of a structure, or of a structure and premises in combination, is discontinued for 12 consecutive months or for 18 months during any three-year period, the nonconforming use shall not thereafter be resumed.  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.
