Tiny Homes in South Carolina

As of March 2026, South Carolina gives foundation tiny homes a better technical code pathway than many buyers realize because the Building Codes Council has continued statewide adoption of the tiny-house appendix in the residential code. That helps local officials approve sub-400-square-foot dwellings with loft and stair provisions tailored to tiny homes.

As of March 2026, the bigger constraint is zoning. THOWs still face the usual RV-versus-dwelling question, while detached tiny homes on foundations must match local land-use, setbacks, utilities, and floodplain rules. Coastal and resort counties can add design and hazard requirements that materially affect project cost.

As of March 2026, Greenville is a useful Tier 1 market because the city-county permitting system is organized and the metro continues to need smaller infill housing, but applicants should still expect full zoning and building review. Verify current requirements with your local planning department.
