Section 497.130 - Airport zoning regulations: Variances1. Any person desiring to erect any structure, or increase the height of any structure, or permit the growth of any tree, or otherwise use the person's property in violation of airport zoning regulations adopted under this chapter, may apply to the board of adjustment for a variance from the zoning regulations in question.2. Such variances shall be allowed where a literal application or enforcement of the regulations would result in practical difficulty or unnecessary hardship, and the relief granted would not be contrary to the public interest but do substantial justice and be in accordance with the spirit of the regulations and this chapter. Any variance may be allowed subject to any reasonable conditions that the board of adjustment may deem necessary to effectuate the purposes of this chapter.12:205:1947; 1943 NCL § 5064.1212:205:1947; 1943 NCL § 5064.12
