Do you need a building permit in Greenville County, South Carolina?
Unincorporated Greenville County requires a permit for a new building, a structural change inside a building or an addition to an existing structure1. Specified electrical, plumbing and mechanical work also requires permits1. Greenville County inspectors enforce the adopted building, residential, plumbing, mechanical, fuel-gas, fire and energy codes12. New-home permit fees depend on heated, garage and basement area, and separate trade and septic fees may apply13. Residential and commercial building-permit fees increased by 20 percent on July 1, 202513. South Carolina's current statewide code edition took effect in 2023, and the next adopted edition is scheduled for implementation in 20271415.
Who issues Greenville County building permits, and how do you reach them?
Greenville County Building Safety & Permitting accepts and processes residential and commercial applications at 301 University Ridge, Greenville County Square, Suite S-3100, Greenville, SC 29601; call 864.467.706016. All county building-permit applications must go through eTRAKiT1116. Greenville County publishes a 5-day processing period for building permits11. Inside Fountain Inn, the city issues building permits; SCDES still handles septic approval where public or community sewer is unavailable1718. Where the permit application requires a Certificate of Occupancy, the building may not be occupied until the county issues it19. For parcel uses, district rules and setbacks, contact Zoning Administration at 864.467.7425 or zoning@greenvillecounty.org8.
Does Greenville County have zoning?
In unincorporated Greenville County, the county administers zoning, but a parcel may be zoned or unzoned; unzoned property is not subject to the county zoning ordinance's use-table restrictions202. Fountain Inn administers its own zoning inside city limits, while SCDES remains the septic authority where public or community sewer is unavailable2118. On zoned land, uses and dimensional standards vary by district3. For example, an R-S lot requires at least 25,000 square feet with public water, and at least 37,500 square feet without public water and sewer22. The AG district may allow one detached accessory dwelling with a principal dwelling, capped at 50 percent of the primary dwelling's gross area and subject to location, driveway and other conditions23. Setbacks on zoned land come from Table 7.3 of the county zoning ordinance and may be supplemented by the plat24. Zoning Administration can verify which of these rules applies at 864.467.7425 or zoning@greenvillecounty.org8.
How do septic permits work in Greenville County?
The South Carolina Department of Environmental Services handles septic permitting for Greenville County homes and manufactured homes without public or community sewer; SCDES approval must precede the building permit5. Submit the Onsite Wastewater System Application (D-1740), a property plat or deed and the $150 application fee5. Traditional permitting includes a site evaluation, with backhoe pits required above the South Carolina Fall Line5. An approved site receives a Permit to Construct, valid for 5 years; renewal after expiration or modifications require a new application and fee5. A licensed installer must install the system and schedule SCDES inspection before covering it; if the inspector does not arrive within 30 minutes of the scheduled time, the licensed installer may self-inspect and must submit Form D-44325. Countywide soil mapping rates about 54.2% of land as free of severe limitations for a conventional drain field, but the SCDES site evaluation controls the actual lot255.
Can you live in an RV or tiny home on land in Greenville County?
In zoned areas of Greenville County, a tiny house on wheels or otherwise movable is classified as an RV and is not permitted for habitation6. Recreational vehicles can be occupied in an approved recreational vehicle park, where each unit must be licensed and ready for highway use, occupancy follows the manufacturer's label, and the park needs an approved water supply and sewer system7. We could not confirm a rule for living in an RV on your own unzoned acreage or for temporary camping outside a park, so ask Zoning Administration about the parcel, duration and utility plan before relying on an RV during construction8. A fixed tiny house is allowed inside a planned residential pocket neighborhood of 4 to 30 houses, which needs a preliminary plan approved by the Planning Commission and, where public sewer is unavailable in unzoned areas, may not exceed 10 houses26. A tiny home built as a stand-alone dwelling still needs the permits required for a new building1. The zoning ordinance sets a 900-square-foot minimum floor area for a multi-section manufactured home, but that standard does not establish a minimum for every house27. A manufactured home without public or community sewer also needs SCDES septic approval before the county building permit45.
What are the steps to build a home in Greenville County?
- Ask Zoning Administration to verify whether the parcel is zoned and which district or municipal rules govern it238.
- Ask Floodplain Administration about flood status and Engineering & Maintenance about road access2829.
- If sewer is unavailable, obtain the $150 SCDES septic Permit to Construct before seeking the county building permit5.
- For a private residential well, file the Notice of Intent before construction and pay the $70 fee10.
- Submit the building-permit application through eTRAKiT and budget for square-footage-based building fees plus any separate trade fees111316.
- Complete the required building and septic inspections before covering the wastewater system3031.
- Obtain the Certificate of Occupancy before moving in when the permit application requires one19.
What should you check before buying land in Greenville County?
Start by determining whether the parcel lies in a municipality, a zoned unincorporated area or an unzoned unincorporated area, because land-use rules differ23. Confirm sewer availability early; SCDES cannot issue an onsite wastewater permit where public sewer is accessible32. Ask Floodplain Administration about flood status and Engineering & Maintenance whether planned access needs an encroachment permit2829. A division into 7 or more lots, or one involving specified street, utility or drainage work, is a major subdivision subject to county review in zoned and unzoned areas33. About 66.8% of Greenville County land has a slope of 15% or less, and about 74.6% is wooded, so examine clearing, driveway grade and usable homesite area on the actual parcel3435. The median property-tax bill is about $1,445 per year, with an effective rate near 0.5%3637.
Watch-outs
- Do not assume every unincorporated Greenville County parcel is zoned; unzoned property is outside the county zoning use table, while zoned property follows district-specific rules23.
- Greenville County requires a paid Greenville Water receipt for all new construction within the county beginning in 2023; confirm how that applies if the parcel is served by another water provider or a private well38.
- A qualifying owner-builder must personally supervise the work, use licensed contractors where required, build for personal or family occupancy and record the required notice; a sale or rental within 2 years creates a presumption against the exemption9.
- A standard qualifying residential driveway within a state-highway right-of-way may be built and permitted by SCDOT, but commercial, speculative and resale projects are excluded39.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
