Unincorporated Anderson County, South Carolina requires a county building permit before any building goes up, issued by the Anderson County Building & Codes Department in Anderson12. Zoning is patchier: Anderson County zones by voting precinct, and only precincts whose voters approved zoning in a referendum are zoned3. On land without sewer, get the SCDES septic permit first, because the county cannot issue a building permit without it4.

Do you need a building permit in Anderson County, SC?
Yes. In unincorporated Anderson County, South Carolina, no building may be erected until a building permit is granted1. Anderson County enforces the 2021 International Building Code and 2021 International Residential Code with South Carolina modifications12. The Anderson County Building & Codes Department issues building, electrical, mechanical and plumbing permits through its OpenGov online portal13. The 2024 state codes take effect for local jurisdictions on January 1, 202714.
Mobile homes need a set-up permit plus an electrical permit7. Owner-builders can build their own one- or two-family home to live in, but must personally supervise the work and use licensed contractors where the law requires them8. Anderson County's owner-builder form asks you to list those licensed contractors before the permit issues9. Selling or renting within two years undercuts the exemption15.
Who is the Anderson County building department, and how do you reach them?
The Anderson County Building & Codes Department is at 401 East River Street in Anderson, phone (864) 260-4158, email [email protected], open Monday to Friday 8:30 a.m. to 5:00 p.m.2. Building, trade, compliance and land-use applications go through the county's OpenGov permitting portal13.
Anderson County publishes Development Standards and Building & Codes fee schedules that took effect July 1, 2026162. A residential building permit costs $110 plus $2.80 per $1,000 of construction cost over $10,000, and plan review adds half the building permit fee7. The county values new homes at a minimum of $150 per heated square foot and garages or storage buildings at $60 per square foot7. Re-inspections cost $657.
Does Anderson County, SC have zoning?
Only in parts of the county. Anderson County practices referendum-based zoning by voting precinct: a precinct is zoned only after 15% of its registered voters petition and a majority votes for zoning3. Check your precinct before you assume a parcel is unzoned; the Planning & Development office at (864) 260-4720 can issue a zoning letter3.
Even in unzoned precincts, the county's Chapter 24 Land Use ordinance applies, and Development Standards reviews land uses, site plans and plats under Chapter 24 and Chapter 4817. In 2026 the county adopted Ordinance 2026-001 increasing minimum lot areas for single-family and twin-home lots, so confirm current lot minimums before you split land17. South Carolina treats a division into parcels of five acres or more with no new street as an exception to subdivision review18.
How do septic permits work in Anderson County?
In Anderson County, septic applications are processed by the South Carolina Department of Environmental Services (SCDES), not the county19. On land without public or community sewer, you must get the SCDES Permit to Construct before the county can issue a building permit4. Apply online; the application fee is $150, an inspector visits the site, and once the permit is issued a licensed installer puts the system in6. For questions before you apply, call SCDES at 1-855-731-250420.
Sites above South Carolina's Fall Line need backhoe pits for the soil evaluation, and you must hire the operator to dig them6. Wet soil can delay the evaluation6. About 80.6% of Anderson County's soils are free of severe limits for a conventional drain field11. SCDES cannot issue a septic permit where public sewer is accessible21. Anderson County Development Standards processes sewer permits only for property served by Anderson County Wastewater22.
Can you live in an RV or tiny home on your land in Anderson County?
We have not confirmed an Anderson County rule on living full time in an RV or a tiny home on your own land. The county has an RV Park Design Ordinance (2023-017), but park rules are not the same as a family living in an RV on its own parcel17. Call Planning & Development at (864) 260-4720 and ask what your precinct's zoning, if any, allows3.
A tiny home built as a house is a dwelling that needs a building permit1. On a septic lot it also needs an SCDES septic permit before the building permit, and SCDES's permit requirement applies to manufactured homes too4. A mobile or manufactured home needs a county set-up permit and electrical permit7.
Building a home in Anderson County: what are the steps, in order?
- Call Planning & Development ((864) 260-4720) to learn whether your precinct is zoned and what lot rules apply3.
- Determine whether the parcel has accessible sewer; Anderson County Development Standards handles permits for Anderson County Wastewater service22. If no public or community sewer is available, apply online to SCDES for the $150 septic permit and arrange backhoe pits when required46.
- If you need a well, file an SCDES Notice of Intent before drilling; the fee is $70 for a residential well10.
- For a driveway onto a county road (a "C" road), get an encroachment permit from Roads & Bridges through the county portal2317. State roads ("S" roads) belong to SCDOT, at (864) 260-221523.
- Apply to Building & Codes through OpenGov; owner-builders also file the subcontractor listing139.
- Request each required building inspection before 4:00 p.m. for scheduling the next business day, and have the permit number ready24.
- Do not occupy the home until every inspection is approved and Anderson County issues the Certificate of Occupancy25.
What should you check before you buy land in Anderson County?
Ask whether public sewer and water reach the parcel; without them you need a septic system and a well26. A septic system must sit at least 75 feet from a private well and 5 feet from property lines, and rocky or shallow-bedrock ground can make land unsuitable26. If a conventional system fails, an engineered system can cost thousands more, and not all property qualifies26.
Check the precinct's zoning status and any pending referendum: Broadview precinct votes on a proposed zoning map on November 3, 20263. Anderson County land is mostly gentle, with 89.7% at 15% slope or less, and 57.4% wooded2728. Farmland averages $7,011 an acre29. Property taxes are low: an effective rate of about 0.5% and a median bill of $985 a year3031.
Watch-outs
- Anderson County zoning can change by vote: Broadview precinct holds a zoning referendum on November 3, 2026, so check whether land you are buying sits in a precinct about to be zoned3.
- Anderson County's building and planning fees rose on July 1, 2026, so older fee quotes are out of date23.
- In Anderson County, the SCDES septic permit must come before the county building permit on any lot without public sewer4.
- Anderson County raised minimum lot areas for single-family and twin-home lots in 2026 (Ordinance 2026-001); confirm current minimums before you split or buy a small lot17.
- Whether you can live in an RV or tiny home on your own Anderson County land is unconfirmed; ask Planning & Development at (864) 260-47203.
