The Madison County Livestock & Fair Association owns a tract of land that has been used as the location for county fairs. The tract is now located in an area in which zoning changes prohibit such uses. The use of the tract as a fairgrounds has been a nonconforming use. The Association filed for a permit to build a race track on the tract. Neighbors objected because they said that such a proposed use could not be grandfathered in under the nonconforming use. Review Perkins v. Madison County Livestock & Fair Ass'n, 613 NW2d 264 (Iowa 2000). Discuss the standards for determining whether a nonconforming use may be changed. Based on the holding in Perkins, can a church located in a residential zone that does not permit office uses, lease out a portion of its administration building to a private company for commercial office use? Why or why not
