Do you need a building permit in Pickens County, South Carolina?
Unincorporated Pickens County, South Carolina requires a building permit for new construction, enforced by the Pickens County Building Codes Administration1. The current statewide code set is the 2021 South Carolina Building Codes, effective since January 1, 20239. The 2024 codes have been adopted but do not take effect in local jurisdictions until January 1, 20278. A qualifying owner may act as the unlicensed builder of a one- or two-family home intended for the owner or the owner's family, but must personally supervise the work, appear to sign the permit application and record the required notice5. A nonresidential farm structure may instead qualify for the agricultural exemption if the owner files an affidavit describing its intended use before construction; residences and structures attached to residences do not qualify6.
Who is the Pickens County building department, and how do you reach them?
Pickens County Building Codes Administration enforces the adopted building codes and county ordinances10. Reach the department at 222 McDaniel Avenue, B-10, Pickens, SC 29671, phone (864) 898-595010. Office hours are 8:00 am to 5:00 pm, Monday through Friday, but permit issuance ends at 4:30 pm even though applications are accepted until closing10. Ask Building Codes which application materials, plan details, inspections and fees apply to the proposed work; the available material does not confirm a complete local permit checklist or fee schedule. Owners pursuing the farm-structure exemption should file the required affidavit with the building-code official before construction begins6.
Does Pickens County have zoning?
Pickens County's Unified Development Standards Ordinance applies to all unincorporated areas of the county2. The published ordinance structure includes a General Development District and separate lot and building standards, but the available material does not establish the detailed use table or the dimensions that apply to a specific parcel11. Pickens County also regulates conventional subdivisions, open-space subdivisions and master planned developments under the ordinance, although the exact thresholds and review steps were not confirmed12. Call the Pickens County Planning Department at (864) 898-5956 to identify the parcel's district and ask about permitted uses, setbacks, minimum lot or dwelling size, subdivision approval and floodplain review before committing to a design or land division13. Municipal parcels can be governed by city rules rather than the county's rules for unincorporated land, so first confirm which jurisdiction controls the address2.
How do septic permits work in Pickens County?
SCDES, not Pickens County, administers onsite wastewater approval, permitting and inspection for property without public or community sewer3. Without an SCDES septic permit, Pickens County cannot issue a building permit, and a Permit to Construct remains valid for five years before renewal or an approved change requires a new application and fee14. During installation, the installer must schedule an SCDES inspection before covering the system; if the inspector does not arrive within 30 minutes of the appointment, a licensed installer may self-inspect on the approved form4. SCDES issues approval to operate when the system meets state standards4. Public sewer accessibility must be checked first because SCDES cannot issue an onsite wastewater permit where public sewer is accessible15. Only about 31.2% of county soils lack severe limits for a conventional drain field, while about 37.7% of the land has a slope of 15% or less, so make the site evaluation an early contingency1617. Reach SCDES at (803) 898-343218.
Can you live in an RV or tiny home on your land in Pickens County?
The available rules do not confirm that long-term RV occupancy or a tiny home is allowed on private land in unincorporated Pickens County. The county's zoning ordinance covers every unincorporated parcel and publishes a General Development District plus lot and building standards, but the detailed use table and parcel-specific dimensions were not established here211. South Carolina's 14-day campsite limit concerns state parks and does not answer private-land occupancy19. Before buying or moving a unit onto land, call the Pickens County Planning Department at (864) 898-5956 and ask whether the parcel's district allows the proposed RV, tiny home or manufactured home as a residence, as well as what setbacks and minimum sizes apply13. A home on land without public or community sewer also needs SCDES approval for its septic system3.
Building a home in Pickens County: the steps, in order
- Call the Planning Department at (864) 898-5956 to identify the parcel's zoning district and ask about use, dimensional, subdivision and floodplain requirements131112.
- Confirm public sewer availability; if sewer is not accessible, apply to SCDES for a septic Permit to Construct before seeking the county building permit1514.
- If you need a well, submit SCDES's Notice of Intent before drilling; the fee is $70 for a residential well and $50 for an irrigation well7.
- Apply to Pickens County Building Codes Administration at 222 McDaniel Avenue, B-10, Pickens, and ask what plans, fees and inspections your project requires10.
- If building under an owner-builder exemption, personally sign the application, supervise construction and record the required notice; if claiming the farm-structure exemption, file the affidavit before construction56.
- Have the septic installer schedule SCDES inspection before the system is covered, then complete the county's required construction inspections410.
What to check before you buy land in Pickens County
Soils and septic: only about 31.2% of Pickens County's soils carry no severe rating for a conventional drain field, and the county is mountainous, with just 37.7% of land at 15% slope or less, so a steep or poorly drained lot may need an engineered septic system that SCDES will approve only after a site evaluation1617. Water: a private well needs an SCDES Notice of Intent and a $70 fee before drilling starts7. Access: a standard driveway onto a state highway is capped at a 16-foot paved throat width unless SCDOT approves more, and additional driveways need separate approval20. Cover and distance: about 80.4% of the county is wooded, and it sits roughly 74 miles from the nearest city of 100,000 or more people2122. Taxes: the effective property tax rate runs about 0.4%, with a median annual bill near $8212324.
Watch-outs
- South Carolina's 2024 building codes were adopted August 26, 2025, but they do not take effect in Pickens County until January 1, 2027, so the current 2021 codes still apply for now8.
- Without an SCDES septic (or sewer) approval, Pickens County will not issue a building permit, so start with the state, not the county, if the land has no sewer connection14.
- South Carolina's owner-builder exemption requires personal supervision, the owner's signature on the permit application and a recorded public notice; sale or rent within two years is evidence that the project was undertaken for sale or rent unless the commission approves otherwise5.
- The farm-structure exemption does not cover a residence or a structure attached to one, and the owner must file an affidavit with the building-code official before construction6.
