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

Edgefield County requires building permits for regulated construction, and permits for all trades on a new home must be issued before work begins^1,8. The county residential packet lists the 2021 South Carolina Building and Residential Codes, the 2020 National Electric Code and the 2009 International Energy Conservation Code⁸. A qualifying owner-builder must build for personal or family occupancy, personally sign the application, supervise construction, use licensed contractors where required and record the statutory notice⁶. Sale or rent within two years after completion or issuance of the certificate of occupancy creates a presumption that the project was built for sale or rent⁶. A farm structure receives no building inspection or owner-builder disclosure, but licensed contractors still need permits and inspections for its electrical, mechanical and plumbing work⁸.

The Edgefield County Building and Planning Department handles building permits, code enforcement and land-development applications². Reach the office at 210 Penn St, Edgefield, SC 29824 or 803-637-4073⁹. Apply online; the county publishes separate application guides for residential homes, manufactured homes, land development, subdivisions and zoning². Building fees may depend on project valuation; the published schedule lists a $10 zoning verification letter and reinspection fees of $40, $80 and $120 for successive reinspections¹⁰. Ask Building and Planning for the complete project fee before submitting the application¹⁰. County-road work orders go through Planning at 803-637-4073 or gwall@edgefieldcounty.sc.gov¹¹. We could not confirm the complete county driveway-approval requirements; ask Building and Planning which road authority controls the parcel's access.

Edgefield County administers zoning in areas delineated on its official maps, and the ordinance also recognizes unzoned areas^3,9. The county rules here concern unincorporated land; North Augusta, a city mainly in Aiken County that reaches into Edgefield County, has its own zoning inside city limits¹². North Augusta also requires a city septic-tank permit after state approval when the city is unable or unwilling to extend sewer; SCDES remains the state septic authority^4,13. County zoning districts govern land use and building placement, spacing and size, with a table of permitted and conditional uses^3,9. On unpaved roads in unincorporated Edgefield County, dwelling lots generally need at least one acre where the right-of-way is at least 50 feet, with larger minimums for narrower or more isolated roads³. Dividing land requires the appropriate minor- or major-subdivision review; ask Planning to classify the proposed split before commissioning the plat^2,14.

For an Edgefield County home or manufactured home without public or community sewer, obtain SCDES approval and a septic installation permit before the county building permit⁴. Apply online with the property plat or deed and the $150 fee; under traditional permitting, SCDES visits the site and issues a Permit to Construct if the site is suitable⁴. The Permit to Construct lasts five years; renewal or approved modifications require a new application and fee⁴. Before covering the system, the installer must schedule the SCDES inspection; a licensed installer may self-inspect using the required form if the inspector has not arrived within 30 minutes⁴. SCDES issues approval to operate after a compliant installation¹⁵. For permit follow-up, Edgefield County falls within SCDES's Sandhills coverage area; contact the Aiken office at (803) 642-1637 or BRLS-OSWW-Field-Admin@des.sc.gov⁴. About 63.1% of county soils are rated without severe limits for a conventional drain field, but SCDES's parcel-specific review controls^4,16.

Edgefield County allows an RV or mobile office during a project's construction phase for no more than one year unless re-permitted, on the property to which the unit relates⁵. We could not confirm a current rule for long-term private-land RV living or one countywide classification for tiny homes; ask Building and Planning about the parcel and exact dwelling type. A residential-designed manufactured home is a specific category requiring at least 900 square feet of enclosed living area, width over 20 feet, a minimum 3:12 roof pitch, specified exterior materials and a roof overhang of at least eight inches³. That definition does not establish a minimum floor area for site-built dwellings or other tiny homes³. Separately, county-regulated manufactured-home park lots must be at least 7,000 square feet and 50 feet wide, with additional space possible for wastewater disposal; those are park-lot standards¹⁷. Confirm the applicable zoning, building-permit path and wastewater approval before placing a dwelling^1,3,4.

1. Ask Building and Planning to identify the parcel's jurisdiction, zoning-map status, allowed use and dimensional standards³.

1. Confirm legal access and any required plat approval; unpaved-road dwelling lots have acreage, right-of-way and emergency-access standards^3,8.

1. Where sewer is unavailable, obtain the SCDES septic Permit to Construct before the county building permit⁴.

1. Submit plans, application, utility authorization and contractor-license information online, then pay the building-permit fee⁸.

1. If using the owner-builder exemption, personally sign, supervise construction, use licensed trades where required and record the notice⁶.

1. Schedule residential inspections at least 24 hours ahead; building permits remain valid for 180 days from issuance or an inspection, with a further 180-day extension available on a written request showing justifiable cause⁸.

1. Obtain final septic approval and submit required closeout documents for the certificate-of-occupancy inspection; occupy the home only after the certificate is issued⁸.

Start by confirming the governing jurisdiction, zoning-map status, legal access and wastewater path; Edgefield County's maps distinguish zoned and unzoned areas³. Unpaved-road lots in unincorporated areas have acreage and access rules tied to right-of-way width, and each dwelling needs driveway access adequate for emergency vehicles³. Special configurations can add requirements: zoned corner lots need room for front setbacks on both streets, and some residential double-frontage lots beside primary state or U.S. highways require a 50-foot rear yard and a 20-foot non-access planting-screen easement³. Edgefield County is 80.7% wooded, so budget for a survey and clearing rather than assuming the homesite is ready¹⁶. A driveway opening onto a non-controlled-access highway in the state primary system requires a Department of Transportation driveway permit¹⁸. Before constructing an individual residential or irrigation well, submit a Notice of Intent to SCDES and use a South Carolina certified well driller⁷. We could not confirm current floodplain-development requirements; ask Building and Planning before purchase.
