Laurens County, South Carolina requires residential building permits, and its Building Codes Department reviews plans, issues permits and performs inspections12. Unincorporated Laurens County has no county zoning ordinance, so it imposes no zoning limits on uses such as RV or tiny-home occupancy, but building, septic, subdivision and other non-zoning rules still apply345. SCDES approval is required before the county can issue a building permit for a home without public or community sewer6.

Do you need a building permit in Laurens County, South Carolina?
Yes. Laurens County requires residential building permits, and the Building Codes Department reviews plans, issues permits and performs in-field inspections12. South Carolina's mandatory 2021 building codes took effect January 1, 2023, although local administrative procedures remain the county's responsibility1314.
A property owner may serve as the unlicensed builder of a qualifying one-family or two-family residence for the owner's or family's occupancy9. The owner must personally sign the application, supervise construction, use properly licensed people where required and record the owner-builder notice; offering the property for sale or rent within two years creates evidence that the exemption did not apply9. The exemption does not waive the permit or building codes9.
Who is the Laurens County building department, and how do you reach it?
The Laurens County Building Codes Department is at 100 Hillcrest Square, Laurens, SC 29360, and its phone number is 864-681-56662. The department reviews plans, issues building permits, enforces construction codes and performs in-field inspections2.
The Laurens County Planning Department sends plats, surveys, subdivisions, commercial development, recreational-vehicle parks, manufactured homes and manufactured-home parks to Building Codes15. The available permit-process information is partial: local building application documents, building-permit fees, inspection stages and certificate-of-occupancy details could not be confirmed, so request the current checklist and fee calculation from Building Codes before preparing plans1614.
Does Laurens County have zoning?
Unincorporated Laurens County has no county zoning ordinance3. It therefore has no county zoning minimum for dwelling size or lot size, and no county zoning controls for setbacks, lot coverage or building height1017111819. Accessory dwellings also face no county zoning restriction in the unincorporated area20.
Those answers are limited to county zoning. New subdivisions and commercial development remain subject to Subdivision Ordinance #926, its appendices and other county-code provisions, while building, septic and floodplain requirements can still affect a parcel321. Incorporated municipalities may have their own rules22.
How do septic permits work in Laurens County?
SCDES requires approval and a septic-installation permit for a Laurens County home or manufactured home not served by public or community sewer, and the county cannot issue the building permit first6. Submit the D-1740 application online with a plat or deed and a $150 fee; a Permit to Construct remains valid for five years623.
After approval, use a licensed onsite-wastewater installer and arrange the SCDES final inspection before covering the system2324. If the inspector has not arrived within 30 minutes of the appointment, a licensed installer may self-inspect and submit the required D-4432 documentation24. Alternative off-grid sanitation is not established as a substitute: the confirmed path for a home without sewer is an approved, permitted and inspected septic system25. About 51.1% of county soils avoid severe limitations for a conventional drain field, so parcel-level evaluation matters26.
Can you live in an RV or tiny home on your land in Laurens County?
Unincorporated Laurens County imposes no county zoning restriction on residential or long-term RV occupancy, temporary camping or tiny-home occupancy475. Manufactured homes likewise face no county zoning restriction, and the county has no zoning-based minimum dwelling size810.
No county zoning restriction is not the same as unconditional occupancy. Building, septic, health, subdivision, floodplain and other county-code rules may still apply, and RV parks or manufactured-home parks may receive separate review48. A tiny home used as a dwelling must still meet applicable construction and permitting requirements27. A manufactured home without public or community sewer needs SCDES septic approval before the county building permit can issue8.
Building a home in Laurens County: the steps, in order
- Confirm that the parcel is in unincorporated Laurens County and ask Building Codes whether plat, survey or subdivision review applies215.
- Verify sewer availability; a home without public or community sewer needs SCDES septic approval before the county building permit6.
- Submit the D-1740 septic application online with the plat or deed and $150 fee, then obtain the Permit to Construct23.
- If using a private residential well, submit the state Notice of Intent before construction12.
- Ask Building Codes for the current plan checklist, fee calculation and inspection schedule, then submit the building-permit application214.
- Complete county building inspections and arrange SCDES inspection before the septic system is covered224.
- For frontage on a state highway, confirm residential driveway access with SCDOT before construction28.
What should you check before buying land in Laurens County?
First confirm whether the parcel lies in unincorporated Laurens County or a municipality because municipal rules may differ22. Ask Building Codes about any plat or subdivision review, and verify legal access with the authority responsible for the road frontage215. SCDOT's cited residential-driveway rule applies only within state-highway rights-of-way, not to every county road28.
Verify public sewer availability and septic suitability before treating the land as buildable6. About 51.1% of county soils avoid severe conventional-drain-field limits26. A new private residential well requires a state Notice of Intent before construction12. The county is 75.6% wooded and 79% of its land has slopes of 15% or less, useful screening context before a parcel survey and site work estimate2930.
Watch-outs

- A home or manufactured home without public or community sewer needs SCDES septic approval before the county building permit can issue6.
- Local building-permit fees, application documents, inspection stages and certificate-of-occupancy details could not be confirmed; request the current requirements from Building Codes216.
