Off-Grid Living in Anderson County, South Carolina

If you're eyeing a piece of land in Anderson County, South Carolina for an off-grid setup, the first thing I want you to understand is that this is not a "no rules, do what you want" county. Anderson County has countywide zoning in unincorporated areas, administered through its Development Standards and Building & Codes departments, and it's fairly tightly linked to state environmental permitting on septic and wells. Let me walk through what I found.

Zoning and land use. Anderson County's Code of Ordinances (Chapter 24 Land Use, Chapter 48 Zoning) gives the county Planning Commission and Board of Zoning Appeals authority over what you can do with your land. If you're inside a municipality like the City of Anderson, that city's own zoning takes over instead. Outside city limits, county zoning applies, and it varies by district, so I can't tell you in general terms whether your parcel allows what you want. Confirm with Development Standards.

Dwellings, tiny homes, RVs. Anderson County requires a Land Use Permit from Development Standards before Building & Codes will even issue a building permit. Manufactured and modular homes need a South Carolina Building Codes Council certification label. The county treats mobile homes as their own regulated category with separate set-up guidelines. Whether you can legally live long-term in an RV on raw rural land, outside a campground, is something I could not confirm from county sources, so ask Building & Codes directly.

Building permits. The county enforces the state-modified International Codes, and permits are tied directly to that Land Use Permit for setback verification. This is a real, functioning permit-and-inspection system, not a rubber stamp.

Septic. This is state-regulated through SCDES (formerly DHEC), but processed locally by the Anderson County Health Department. No septic permit, no building permit, full stop, according to the county's own septic application instructions. Composting toilets don't have their own county carve-out that I found; treat them as falling under the same state onsite wastewater regulation until told otherwise by the health department.

Greywater and rainwater. I found no Anderson-County-specific rules on either. Greywater likely falls under the same statewide onsite wastewater framework as septic. Rainwater harvesting doesn't seem to be addressed anywhere at the county level, so this one is genuinely unclear, ask Building & Codes before you install a cistern system.

Wells. Regulated by the state (SCDES) under its residential well permitting rules; there's no separate Anderson County well permit process. If you're sharing a well between structures, the county's Environmental Quality Control office gets involved.

Utilities. Nothing I found forces you to hook up to the electric or public water grid. But "off-grid" here still means you must clear the Land Use Permit, building permit, septic permit, and (usually) a state well permit. Going off-grid legally in Anderson County is a paperwork chain, not a loophole.
