Variances. To vary strict application of the requirements of this chapter in the case of exceptionally irregular, narrow, shallow or steep lots or other exceptional physical conditions, whereby strict application would result in practical difficulty or unnecessary hardship that would deprive the owner of the reasonable use of the land or building involved. No variance shall be granted which permits a use otherwise not permitted in that district. In granting any variance, the Board shall prescribe conditions that it deems to be necessary or desirable. No variance in the strict application of any provision of this chapter shall be granted by the Board unless it finds that:
(1)
Strict application of the chapter would produce undue hardship and that the hardship is not self-created, nor an economic hardship.
(2)
The hardship is unique and is not shared by all properties alike in the immediate vicinity of the property and the district.
(3)
The variance would observe the spirit of the chapter and would not change the character of the district, be injurious to the neighborhood or otherwise detrimental to public welfare.
(4)
The variance would observe the intent of the Comprehensive Plan.
(5)
The variance is the minimum necessary to grant relief.
