Zoning regulations are necessarily rigid and meant to be applied uniformly within a district. Still, there are certain instances, due to a unique situation, such as topography, when their strict enforcement would result in an inappropriate hardship to a property owner. In such cases, where a verifiable hardship exists, the property owner or authorized agent may make an application for a variance of the zoning regulations as they apply to the circumstance. Variances are in effect, a relief valve for the Zoning Ordinance, in that they provide limited exemption for unique cases.
