Unincorporated Laurens County requires residential building permits, and the Building Codes Department reviews plans, issues permits and performs in-field inspections1. South Carolina's 2021 building codes took effect January 1, 2023; ask Building Codes which edition applies to a new application because the currently enforced Laurens County edition could not be confirmed7.
South Carolina's owner-builder exemption allows a property owner to serve as the unlicensed builder of a qualifying one-family or two-family residence for the owner's or family's occupancy5. The owner must personally appear to sign the building-permit application, supervise construction, use properly licensed people where required and record the owner-builder notice; failure to record revokes the exemption, and offering the property for sale or rent within 2 years after completion or issuance of a certificate of occupancy creates evidence against the exemption unless the commission approves otherwise5. A separate state provision narrowly exempts listed building, electrical, gas, mechanical and plumbing improvements performed by the residential property owner; it does not establish a blanket exemption for a new home5.

How do septic permits work in Laurens County?
SCDES is the septic authority for Laurens County properties not served by public or community sewer.
SCDES is the septic authority for Laurens County properties not served by public or community sewer4. SCDES requires approval and a septic-installation permit for a home or manufactured home on such property, and the county cannot issue the building permit first3. Submit the D-1740 application online with a plat or deed and a $150 fee; a Permit to Construct remains valid for five years3.
The installer must arrange the SCDES inspection before covering the system3. If the inspector has not arrived within 30 minutes of the appointment, a licensed installer may self-inspect and submit the required D-4432 documentation3. Off-grid sanitation is therefore limited: a home or manufactured home without public or community sewer still needs an approved, inspected onsite system3. About 51.1% of county soils avoid severe limitations for a conventional drain field, so parcel-level evaluation matters16.
