No variance in the provisions or requirements of this chapter shall be effected by the Board of Appeals unless it finds from reasonable evidence that such variance will not be of substantial detriment to adjacent property and will not materially impair the intent and purpose of this chapter or of the public health, safety and welfare and, further that, at least two of the following facts and conditions exist:
(A) There exists exceptional or extraordinary circumstances or conditions applying to the specific property that do no apply generally to other properties in the same zone;
(B) Such variance is necessary for the preservation and enjoyment of a substantial property right similar to that possessed by other properties in the zone; provided that, increased financial return shall not be deemed sufficient to warrant a variance; and
(C) The condition or situation of the specific property or the intended use is not of so general or recurrent a nature as to make reasonably practical a general regulation as part of this chapter.
