North Carolina Tiny House Zoning Laws Overview
North Carolina organizes local land‑use authority under **Chapter 160D**, which unifies city and county powers to plan, zone, and regulate development. The **NC Office of State Fire Marshal** publishes the state building codes and effective‑date bulletins; the **2024 NC State Building Code** (based on 2021 ICC) includes **Appendix AQ: Tiny Houses** with published effective and mandatory dates, though subsequent bulletins may adjust timing. There is no statewide ADU mandate, so eligibility for a small home on a foundation depends on the local ordinance/UDO in your jurisdiction. By contrast, tiny houses on wheels (THOWs) are handled as vehicles for DMV purposes unless a city/county reclassifies them for residential use. The practical path is to determine whether your parcel is inside city limits/ETJ or in the unincorporated county, read the zoning text for ADU allowances, and work with Planning & Inspections to confirm setbacks, utilities, stormwater, and fire access.

NC has no statewide ADU mandate; tiny houses on wheels are generally treated as vehicles unless locally authorized as dwellings.
