  • Building/fire codes are set statewide, but whether an ADU is allowed is local zoning.
  • There is active proposed legislation (H627 / S495, "Regulation of Accessory Dwelling Units") that would create G.S. 160D-917 and require local governments to allow at least one ADU in certain single-family areas, but it is not enacted.
