A permit for a septic system comes from the state, through SCDES, the environmental department that used to be part of SCDHEC before a 2024 split created a separate health department for public health work. Local health departments and county environmental health offices handle this in some other states. Here, it stays with one agency, and here's how we work it for you.
- We contact the SCDES regional office and submit your address or parcel number. This visit carries the state's $150 site evaluation fee.
- We schedule the soil evaluation that checks drainage, depth to rock, and what system type your lot can support under state code.
- We handle the back-and-forth while SCDES reviews and has to approve the layout before issuing the permit.
- We coordinate the final inspection once construction wraps up. An inspector confirms everything matches what SCDES approved before signing off, so the system gets cleared for use without extra delay on your end.
As of August 2026, having Rock Solid manage this whole process runs $1,500–2,500 depending on site conditions.
Older permit files may only go back so far. Records from before the mid-1990s were sometimes hand-drawn, and some parcels near the lakes and mountains were platted before current rules existed. If a lookup turns up nothing, we send a licensed septic contractor to confirm what's actually installed.
