Off-Grid Living in Lee County, South Carolina

I'll be upfront: Lee County, South Carolina isn't a place where I could find a lot of detailed public ordinance text to dig through. That doesn't mean the county has no rules, it just means the specifics live in documents I couldn't locate on an official host during this research pass. Here's what I could confirm, and where I'm telling you flatly to call and ask.

Zoning. South Carolina's Zoning Enabling Act gives counties the authority to zone, and Lee County does exercise that authority through its Planning and Zoning Department, which handles permitting and code enforcement countywide. What I couldn't find were the actual district maps or text, so if you're eyeing a piece of raw land for occupancy, don't assume anything about minimum lot sizes or allowed uses until you call the county office directly.

Dwellings, tiny homes, RVs. Same story, no official ordinance language on tiny home siting or RV occupancy standards turned up in my search. The Planning and Zoning Department issues all building permits in the county, so they're the ones who'll tell you whether your structure qualifies as a dwelling and what's required.

Building permits. This one's clear: Lee County requires building permits for construction countywide, administered by Planning and Zoning, with inspections handled by a third-party inspection company (except Fire Marshal inspections). You schedule inspections through the county's Evolve portal or by phone.

Septic. This is a state matter, not a county one. As of July 1, 2024, septic permitting authority moved from DHEC to the newly formed South Carolina Department of Environmental Services (SCDES). If your home won't be on public or community sewer, you need SCDES approval and a septic permit before Lee County will issue a building permit. I found nothing addressing whether composting toilets can substitute for this, so ask SCDES directly.

Greywater. No Lee County ordinance here either, this defers entirely to SCDES's statewide requirement that greywater reuse go through an engineered subsurface system.

Rainwater harvesting. No county-specific rule found. The safe move is to check with Lee County Planning and Zoning before installing a catchment system, since the state baseline is what would apply otherwise.

Wells. Also a state function. SCDES governs well construction and permitting standards; I didn't find any Lee County addition to that.

Off-grid utilities. No ordinance mandates grid connection in Lee County. But going off-grid electrically doesn't get you out of building permit, septic, or well requirements, those still apply through the county and SCDES respectively.

Bottom line: Lee County has real zoning and permitting authority, it's not a "no rules" rural county, but a lot of the fine print wasn't available to me in public documents. Treat the offices below as your first stop before you buy land or start building.
