Who inspects or services a septic system in South Carolina?

A contractor licensed by SC DES under Regulation 61-56. South Carolina licenses septic professionals as Installers (Tier I, II, or III), Pumper/Haulers, and Tank Manufacturers; there is no separate state 'inspector' license, so buyers hire a licensed installer or pumper to evaluate the system. Each professional listed here carries a DES permit number you can verify.

A visual inspection typically runs a few hundred dollars and a tank pump-out is similar; a combined inspect-and-pump costs more. See the cost table on this page.

What do the installer tiers mean?

South Carolina grades septic installer licenses by the complexity of systems they may install. Tier I covers the most basic systems, Tier II conventional systems, and Tier III the full range including complex and alternative systems.

Summary of record

Is an inspection required?

South Carolina does not require a statewide point-of-sale septic inspection. Onsite wastewater systems are regulated under DES Regulation 61-56, administered by the South Carolina Department of Environmental Services (DES, formerly DHEC). New construction and repairs require a permit, and the licensed installer submits a final inspection form (DES 4432) to the Department. For a home sale, a septic inspection or pump-out is typically a lender or buyer requirement, performed by a DES-licensed septic contractor rather than mandated by the state.

Typical inspection cost

$250 to $500 for a standard inspection. See the cost breakdown.

Who may inspect

Only a Licensed OSWW Contractor (Installer / Pumper / Manufacturer). Every inspector below lists the license number you can confirm against the state roster.
