Read this before you act on anything below. This is my researched starting point for Greenville 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 rulesGreenville County, SC

Zoning & raw-land occupancy

Varies locallyGreenville County Planning & Development administers countywide zoning, but some unincorporated areas remain unzoned, and allowed uses (like backyard tiny homes) differ sharply between zoned and unzoned parcels. Municipalities within the county have their own separate codes. source

Dwellings, tiny homes & RVs

RestrictedGreenville County distinguishes RVs (not permitted as permanent dwellings in zoned areas), SC-labeled modular homes (permitted as modular), and compliant stick-built tiny homes (permitted as new residential construction), per county Zoning guidance. source

Building permits & codes

Generally allowedGreenville County has adopted its own building code enforcing state ICC-based standards; building permits and inspections are mandatory for construction countywide. source

Septic & composting toilets

RestrictedSince 2020 all septic applications for Greenville County properties are handled directly by the state agency SCDES (formerly DHEC), not a county office; composting toilet rules are not confirmed. source

Greywater reuse

RestrictedNo Greenville County-specific greywater ordinance was found; this inherits the state SCDES baseline, which generally requires an engineered subsurface reuse system.

Rainwater harvesting

Unclear - verifyNo Greenville County policy on rainwater harvesting, cisterns, or catchment was found; confirm directly with County Zoning or Building Safety before installing a system.

Private wells & water rights

RestrictedPrivate wells are permitted entirely by the state agency SCDES under South Carolina's well permitting regulation, with a required Notice of Intent and a state-certified driller; the county has no separate well ordinance. source

Living disconnected from utilities

Varies locallyNo county rule mandates grid electric connection, but building, septic, and well permitting still apply to off-grid structures, and zoned-area occupancy rules attach regardless of utility hookups. source
