Tiny home rules in York County, SC — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
A tiny house in York County is a legal dwelling only if built to the 2021 SC Residential Code, which adopts Appendix AQ for homes 400 square feet or less. A tiny house on wheels is treated as an RV, not a permanent dwelling.
South Carolina's 2021 Residential Code includes Appendix AQ, which applies to tiny houses used as single dwelling units and defines a tiny house as a dwelling 400 square feet or less excluding lofts; it relaxes stair, loft, and emergency-escape rules for such homes. York County permits a tiny house built to this code on a foundation, with zoning review and, off public sewer, a SCDHEC 61-56 septic permit. A tiny house on wheels is a recreational vehicle and cannot be permitted as a permanent dwelling; the county grants no certificate of occupancy for it.
Placing a tiny house without a building permit is illegal construction. Living permanently in a tiny house on wheels or an RV is prohibited; the county grants no occupancy for it.
