(A) The Board shall not vary the regulations of this chapter, as authorized in this section, unless there is evidence presented to it in each specific case that:
(1) Because of the particular physical surroundings, shape or topographical conditions of the specific property involved, a particular hardship to the owner would result, as distinguished from a mere inconvenience if the strict letter of the regulations were to be carried out;
(2) The conditions upon which a petition for a variation is based are unique to the property for which the variance is sought and are not applicable, generally, to other property within the same zoning classification;
(3) The purpose of the variance is not based exclusively upon a desire to make money out of the property;
(4) The alleged difficulty or hardship is caused by this chapter and has not been created by any persons presently having an interest in the property;
(5) The granting of the variance will not be detrimental to the public welfare or injurious to other property or improvements in the neighborhood in which the property is located;
(6) The proposed variance will not impair an adequate supply of light and air to adjacent property, substantially increase the congestion of the public streets, increase the danger of fire, endanger the public safety or substantially diminish or impair property values within the neighborhood; and
(7) The purpose of the variance shall not be to establish a use otherwise excluded from the particular district in which it is requested.
(B) The Board may impose such conditions and restrictions upon the premises benefitted by a variance as may be necessary to comply with the standards established in this section.
