There are conditions that apply to the land or structures for which the variance is sought, which conditions are peculiar to such land or structures and not to the personal or financial circumstances of the appellant, and which conditions are not affecting generally the area in which such land or structure is situated. Minor infractions in the location or height of a structure or the dimension or area of a lot, caused by human error, may be considered sufficient cause for an affirmative finding of this subsection, unless, in the opinion of the Board, such infractions can be repaired without impairing the use of the land or structure.
