How much will it cost to build a prefab in South Carolina?
Many owners budget about $150–$200 per sq ft for prefab construction in South Carolina (home-only), with totals varying by finishes, site work, and location. Coastal areas like Charleston and Myrtle Beach typically add higher permitting and hurricane-zone foundation costs; rural areas may require added expenses for septic systems, well drilling, site preparation, and foundation considerations for South Carolina's varied soil types and climate zones.

Zoning & Permits
South Carolina enforces statewide building codes, with the 2021 International Residential Code adopted effective January 1, 2023. The South Carolina Building Codes Council adopts and modifies model codes for the state. State codes must be enforced in all local jurisdictions. The UpCodes South Carolina Building Codes resource provides comprehensive information. Local municipalities enforce state codes and may have additional local requirements for zoning, setbacks, and land use.
Off-Grid & Rural Builds
For rural builds not connected to public sewer, individual septic systems (onsite wastewater systems) are regulated by the South Carolina Department of Environmental Services under Regulation 61-56. You must obtain a permit before installing a septic system, which your county requires before issuing a building permit. Site evaluations assess soil suitability, and systems must be installed by licensed contractors. Permits are valid for five years.
Energy Code & Efficiency
South Carolina has adopted the 2009 International Energy Conservation Code (IECC) as the state energy standard, effective January 1, 2013. The energy code is adopted by statute through the South Carolina General Assembly and is mandatory statewide. Future updates to the energy code must be adopted by statutory amendment. The Building Codes Assistance Project South Carolina provides detailed information on energy code adoption and compliance. Local jurisdictions may adopt more stringent energy codes.
Local Zoning Tools
Zoning in South Carolina is administered at the municipal and county level. Each jurisdiction enforces its own zoning ordinances for dimensional requirements, setback distances, and land use regulations. While the state building code provides a baseline, local governments enforce these codes and may have additional requirements. Contact your local planning or zoning department for site-specific requirements. Coastal areas may have additional regulations for hurricane zones, flood zones, and elevation requirements.
Tip
If you're unsure about your parcel's status—whether it requires septic system approval through SCDES, falls under local zoning jurisdiction, or needs specific foundation requirements for coastal or hurricane zones—contact your local building department or SCDES directly. In South Carolina, municipalities like Charleston, Columbia, Greenville, and Myrtle Beach all have different local requirements. The resources above are a great place to start.
