The right to a nonconforming use will terminate upon the following events:
(a) Voluntary Discontinuance or Abandonment. Whenever a nonconforming use has been discontinued for a period of six (6) months or more, a presumption of abandonment of the nonconforming use shall be established and any further use shall be in conformity with the provisions of this UDO. The individual or entity claiming the continuance of the nonconforming use then bears the burden of proving the use has been continuous by a preponderance of the evidence. For purposes of determining whether a right to continue a nonconforming situation is terminated, all of the nonconforming buildings, activities, and operations maintained on a lot are generally to be considered as a whole.
(b) Where a nonconforming use is changed to a more conforming use, the use shall not later be changed back to a less conforming use, as determined by the Planning Commission.
(c) Determination of Public Nuisance. If the planning commission or court of law finds that a particular nonconforming use constitutes an actual nuisance which immediately or directly affects public health, safety, morals, or general welfare.
(d) If a nonconforming building or structure is destroyed more than fifty (50) percent of the appraised valuation of the structure to be renovated. All costs resulting from such appraisal shall be incurred by the owner of such nonconforming lot.
