Off-Grid Living in Georgetown County, South Carolina

I've been digging into what it actually takes to live off-grid in Georgetown County, South Carolina, and the short version is: this is a zoned county, which changes the calculus compared to some of South Carolina's unzoned rural counties.

Zoning first. Georgetown County actively administers its own zoning ordinance countywide through its Building, Planning & Zoning Department, and it's currently rolling those rules (plus subdivision regs) into a new Unified Development Ordinance. That means where you can put a dwelling, and what kind, depends on the zoning district your parcel sits in. Big caveat: if your land is inside the City of Georgetown, Pawleys Island, or another incorporated town, that municipality's own zoning code controls instead of the county's. Always confirm which jurisdiction you're actually in before you plan anything.

Dwellings, tiny homes, RVs. The county requires compliance with state-adopted residential building codes. RVs are treated as vehicles, not permanent residences, and county practice generally follows the statewide pattern of not permitting full-time RV living outside licensed RV parks. I've seen commercial sites claim Georgetown County welcomes IRC-compliant tiny homes, but I couldn't verify that on an official county page, so treat it as unconfirmed and call the Building, Planning & Zoning Department directly.

Building permits are mandatory for permanent structures, administered by the county through the state building code adopted by South Carolina's LLR Building Codes Council.

Septic falls under the state agency SCDES (formerly DHEC): you need their approval and permit before the county will issue a building permit for a home not on public sewer. I also found a claim that Georgetown County requires septic transfer inspections at the point of sale, an add-on beyond the state baseline, but that came from a non-official source, so it's not confirmed, call the county's environmental health contact through SCDES to check.

Greywater and rainwater have no county-specific ordinances that I could find; both default to the state SCDES framework, and rainwater harvesting rules in particular are simply not addressed anywhere I could locate. Confirm with the county before building a system tied to potable or greywater use.

Wells are regulated statewide by SCDES. Separately, much of the populated county is served by the Georgetown County Water & Sewer District, a special-purpose district (not part of county government) that draws groundwater on the Georgetown side and surface water on the Waccamaw Neck. If you're not connected to their system, private well permitting still runs through SCDES.

Going fully off-grid? No law forces a grid or utility hookup, but any inhabited structure still triggers septic and building-permit requirements, and municipal boundaries can add their own utility-connection rules the county doesn't have. Figure out your parcel's exact jurisdiction first, it changes everything downstream.
