Union County, North Carolina
Union County sits southeast of Charlotte along the South Carolina line, anchored by Monroe and defined by fast-growing suburbs like Indian Trail and Waxhaw that have replaced much of its farmland. It is one of the fastest-growing counties in the state, and Charlotte's expansion keeps pressure on new subdivisions, so school attendance zones and each town's growth ordinances weigh on what a parcel can become.
