South Carolina Septic Regulations

South Carolina septic systems are regulated by the Department of Health and Environmental Control (DHEC) under the Onsite Wastewater Systems standards (R.61-56). Permits are required for the installation, alteration, and repair of onsite wastewater systems. Time-of-transfer inspections are not mandated statewide, though lenders may require one.

• Onsite wastewater permits are issued by DHEC's regional environmental health offices and require a site evaluation and soil analysis.
• South Carolina requires licensed installers for onsite wastewater system installation and major repairs.
• DHEC rules establish minimum setback distances from wells, surface waters, marshes, and property lines for all onsite wastewater systems.
• South Carolina does not mandate a statewide time-of-transfer septic inspection, though coastal counties may have additional requirements for properties near tidal waters.
• Systems must be designed to meet DHEC standards based on site and soil conditions, with special attention to high water tables in coastal and Lowcountry areas.
• DHEC regional offices maintain records of permitted systems — contact the local DHEC office for records before purchasing property.
