Read this before you act on anything below. This is my researched starting point for Anderson County, SC, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesAnderson County, SC

Zoning & raw-land occupancy

Varies locallyAnderson County has countywide zoning outside municipalities, administered by the county Planning Commission, Board of Zoning Appeals, and Development Standards under Chapters 24 and 48 of the county code. Incorporated cities like Anderson have their own separate zoning. source

Dwellings, tiny homes & RVs

RestrictedA Land Use Permit from Development Standards is required before Building & Codes issues a building permit, and manufactured/modular homes need state Building Codes Council certification labels. Long-term RV living on raw land outside a campground is not confirmed by county sources; ask Building & Codes. source

Building permits & codes

Generally allowedAnderson County Building & Codes enforces the state-modified ICC codes and ties permit issuance and inspections to the Land Use Permit's setback verification. This is an active permit-and-inspection process. source

Septic & composting toilets

RestrictedSeptic systems require a state (SCDES, formerly DHEC) permit, processed locally through the Anderson County Health Department, and a building permit will not be issued without it. Composting toilets aren't separately addressed and likely fall under the same state onsite wastewater rule. source

Greywater reuse

RestrictedNo Anderson County-specific greywater ordinance was found; it appears to fall under the same statewide onsite wastewater regulation (Reg. 61-56) that governs septic systems. source

Rainwater harvesting

Unclear - verifyNo county ordinance or guidance on rainwater harvesting was found. This is not confirmed either way, so check directly with Anderson County Building & Codes before installing a system.

Private wells & water rights

RestrictedPrivate wells are regulated entirely by the state (SCDES) under its residential well permitting rules; there is no separate county well-drilling permit. Shared wells serving multiple structures involve the county's Environmental Quality Control office. source

Living disconnected from utilities

Varies locallyAnderson County does not appear to mandate connection to public electric or water utilities, but occupying a dwelling still requires the Land Use Permit, building permit, septic permit, and often a state well permit to be legally satisfied. source
