Which codes and exemptions should I review?
Barnwell County states that it adopted the 2021 International Building Code, 2021 International Residential Code, and 2021 South Carolina State Building Codes. South Carolina's 2021 mandatory cycle also governs the fire, plumbing, mechanical, fuel-gas, electrical, and energy codes for 2026 work; the statewide 2024 cycle is scheduled for implementation January 1, 2027. N/A — the county building page did not publish a general minor/cosmetic exemption list. The separate mobile/manufactured-home ordinance identifies limited exceptions for storage-only manufactured homes, certain unoccupied homes held for resale, and construction-related homes or travel trailers when a temporary-use permit is obtained; confirm ordinary repairs and cosmetic work with the Building Inspector and Zoning Department.
