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 rulesFlorence County, SC
Zoning & raw-land occupancy
Varies locallyFlorence County (unincorporated) has a countywide zoning ordinance and land development ordinance administered by the Planning Department; specific allowances for off-grid use by district weren't confirmed, so check your parcel directly. Cities/towns within the county have their own separate zoning. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Florence-County-specific rule on RVs or tiny homes as permanent dwellings was found; this needs to be confirmed with County Planning/Inspections since neighboring counties handle it differently. source
Building permits & codes
Generally allowedFlorence County requires a formal building permit process, including zoning compliance, proof of water/sewer arrangements, contractor licensing checks, and plan review, enforcing state-adopted building and residential codes. source
Septic & composting toilets
RestrictedAny dwelling not on public/community sewer needs a septic permit from SCDES (successor to DHEC) before the county will issue a building permit; composting toilets as a standalone option are not confirmed. source
Greywater reuse
RestrictedNo Florence County-specific greywater ordinance was found; this falls back to the state baseline, which requires engineered systems for reuse rather than informal setups.
Rainwater harvesting
Unclear - verifyNo Florence County or confirmed state rule on rainwater harvesting (cisterns, catchment) was found; ask County Planning before installing a system.
Private wells & water rights
RestrictedPrivate wells are regulated statewide by SCDES under its well standards regulation, requiring a licensed SC well driller and a permit before drilling; the county folds proof of water arrangements into its own permit checklist.
Living disconnected from utilities
Varies locallyNo explicit rule forcing grid electrical connection was found, so solar-only power looks workable if the structure meets code, but going without a permitted septic/well setup entirely is not confirmed as allowed. source
