Off-Grid Living in Dillon County, South Carolina

I've been digging into what off-grid living actually looks like in Dillon County, South Carolina, and the short version is: it's doable, but you're stacking three layers of rules (state, county, and possibly town) depending on exactly where your parcel sits.

Zoning is handled at the county level by the Dillon County Zoning Administrator, under the Planning Commission and County Council, and the county does have a countywide Zoning Ordinance. But if your land is inside the City of Dillon, Latta, or Lake View town limits, that municipality runs its own separate zoning code, and the City of Dillon in particular has its own zoning chapter and administrator. Before you buy or build anything, I'd call the county zoning office (or the relevant town office) and confirm which district you're in and what it allows.

Dwellings, tiny homes, and RVs are trickier here. Dillon County does have a Manufactured Housing chapter in its Code of Ordinances, which tells me the county separately regulates mobile/manufactured homes, but I could not pull the actual siting standards or occupancy limits from the source I found. I'd treat tiny-home and RV-as-residence rules as unconfirmed and call the Zoning Department directly rather than trust a generic "county rules" article floating around online.

Building permits are mandatory. In unincorporated Dillon County, the Building Code Enforcement Department issues permits and inspects construction, electrical, plumbing, and mechanical work. Inside Dillon city limits, you go through the city's own Code Enforcement Department instead.

Septic systems are regulated at the state level now through SCDES (South Carolina Department of Environmental Services, which took over from DHEC in mid-2024), under Regulation 61-56. You need a site approval and permit for any septic system not tied to public sewer, and the county won't issue a building permit without it. Composting toilets aren't addressed anywhere I could find for Dillon County specifically, so ask SCDES directly.

Greywater reuse inherits that same state framework, meaning informal reuse without SCDES approval isn't permitted; there's no Dillon County-specific rule layered on top.

Rainwater harvesting is a genuine gray area. I found no county ordinance or state rule specifically addressing catchment systems, so it likely falls under general plumbing/building code review rather than a dedicated statute. Worth a call before you install anything large-scale.

Wells are governed by state well standards (SCDES, tied to Regulations 61-71/61-44) rather than any Dillon County-specific well office, administered through SCDES's regional office network.

Bottom line on utility disconnection: nothing I found bans living off-grid in Dillon County outright, but you still need a building permit for any inhabited structure, a septic permit if you're not on public sewer, and compliance with state well rules if you're drilling your own water source.
