   (E)   No building, structure, or premises where a non-conforming building or structure which has been or may be discontinued for more than one year, or has been or may be changed to a use permitted in the district in which it is located, shall again be devoted to a non-conforming use.
   (F)   Any building or structure devoted to a non-conforming use with a fair market value of less than

   (G)   (1)   Any legal, non-conforming use shall be enclosed in all sides by a solid wall or tight board fence not less than eight feet high if said use includes storage, repair or maintenance of vehicles, equipment, or materials on the premises and not within the building.

   (J)   No non-conforming building in any Residential District shall be so altered as to increase the number of dwelling units therein.
   (K)   No non-conforming use may be enlarged or extended in such a way as to occupy any required usable open space, or any land beyond the boundaries of the zoning lot as it existed at the effective date of this chapter, or to displace any conforming use in the same building or the same parcel.
   (L)   Where a use is classified as a special use under this chapter and exists as a special use or permitted use at the date of the adoption of this chapter, it shall be considered to be a legal special use.
   (M)   Where a use is not allowed as a special or permitted use under this chapter or at the date of the adoption of this chapter and exists as an additional use as provided in the County Zoning Ordinance adopted July 1995, as amended, it shall be considered to be a non-conforming use and shall be subject to the applicable non-conforming use provisions of this section.
