Building permits, zoning and land rules in Abbeville County, South Carolina

Unincorporated Abbeville County requires a building permit for a new house and any structure larger than 200 square feet¹. Separate building, electrical, plumbing and mechanical permits follow zoning compliance, required septic documentation and plan approval¹. The county enforces the 2021 South Carolina Building Codes, effective in 2023⁷. The county links a building-permit fee schedule; ask Building and Codes for the current total because the county-hosted 2018 schedule may be outdated^1,8. Inside Abbeville city, the county Building Department and City Zoning Office provide building-construction permits; septic approval remains with the state^1,2.

The Abbeville County Building and Codes Department handles building, electrical, plumbing and mechanical permits, plan review and construction inspections¹. Its office is at 903 West Greenwood St., Suite 2100, Abbeville, SC 29620, and its phone is (864) 366-2400, ext. 2224¹. Applications can begin through the county-linked online permitting portal¹. A Building Inspector reviews plans before permits are issued, and the county asks for at least 24 hours' notice when requesting an inspection¹. Ask the department for the current submittal requirements and fee before filing.

Abbeville County administers zoning in its unincorporated area, and a new-house building permit starts with a zoning-compliance signature^1,4. Inside Abbeville city, the City Zoning Administrator administers the city ordinance; SCDES still handles septic approval^2,9. Ask county Planning and Zoning at (864) 366-2400, ext. 64 for the parcel's district and allowed dwelling count⁴. R-8 setbacks are 25 feet front, 10 feet side and 15 feet rear; GR setbacks are 25 feet front, 10 feet side and 10 feet rear, with a minimum lot size of 8,000 square feet^10,11. In the Manufactured Housing (MH) district, parks need at least 7 acres, and independent mobile-home spaces need at least 5,000 square feet and 100 feet of width¹². We could not confirm complete lot-coverage or height limits; ask Planning and Zoning for the parcel's standards.

For a home or manufactured home without public or community sewer, obtain SCDES approval and a septic installation permit before Abbeville County can issue the building permit^3,9. Apply online with the property plat or deed; the application fee is $150, and an approved Permit to Construct remains valid for 5 years³. A licensed installer must schedule SCDES inspection before covering a new system³. Start with SCDES Onsite Wastewater Customer Support at 1-855-731-2504 or OSWWCentral@des.sc.gov¹³. About 48.5% of county soils lack severe limits for a conventional drain field, so parcel-level evaluation matters¹⁴. SCDES administers installation inspection and approval to operate as well as the Permit to Construct⁹. In Due West, the town building inspector also inspects and approves septic construction and drainage¹⁵.

A camper cannot serve as a primary residence in unincorporated Abbeville County⁴. Periodic camper stays may be approved in the Forest Agricultural district when county conditions are met and Planning and Zoning issues approval⁴. RV use may also be allowed under certain circumstances in the Mobile Home Park district and in business and industrial zones, but occupancy is barred in the R-8 and GR residential districts at any time⁴. A small or tiny home may be occupied as a residence because the county sets no particular minimum floor area, but it must meet the same building-code requirements as any other new home¹. Commercial campgrounds and RV parks, where permitted, need at least 5 acres, with structures and RVs set back 100 feet from street rights-of-way and 50 feet from other property lines; these are park standards, not permission to live in an RV on a private lot¹⁶.

1. Ask Planning and Zoning to confirm the parcel's district and obtain the zoning-compliance signature and address-request form¹.
2. If public or community sewer is unavailable, apply to SCDES for septic approval; an existing system requires an adequacy letter from a licensed contractor^1,9.
3. For owner or family occupancy, an owner-builder must personally sign the application, supervise construction, use licensed contractors where required and record notice with the register of deeds; the exemption does not authorize hiring unlicensed persons⁵.
4. Submit plans for Building Inspector review, then obtain the separate building, electrical, plumbing and mechanical permits¹.
5. Request county inspections with at least 24 hours' notice and arrange the SCDES inspection before a new septic system is covered^1,3.

Start with zoning and septic: confirm the parcel’s district with Planning and Zoning, then determine whether sewer is accessible because SCDES cannot issue an onsite-wastewater permit where public sewer is accessible^4,17. For a private residential well, South Carolina requires a Notice of Intent before construction; the stated fee is $70, and the driller must give SCDES 48 hours’ installation notice⁶. Check road ownership too: a standard residential entrance on a state highway goes through SCDOT, while the county Public Works process for county-road encroachments should be confirmed separately¹⁸. Abbeville County is 73.5% wooded and 80.1% of its land has slopes of 15% or less, but those countywide figures do not replace a survey or site evaluation¹⁴. The effective property-tax rate is about 0.5%, with a median annual bill near $717¹⁴.
