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

Zoning & raw-land occupancy
Varies locallyRichland County (unincorporated areas) has its own countywide zoning administered by Planning and Development Services, with multiple district types; whether off-grid occupancy is allowed depends on the specific parcel's district. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official Richland County text on tiny home minimum size or RV-as-dwelling rules was found; commercial sources make claims that are not confirmed by the county. Verify with the county Zoning Office for your parcel. source
Building permits & codes
Generally allowedRichland County requires building permits under the statewide code adopted by the SC Building Codes Council, administered by the county's Building Permitting and Inspections department. source
Septic & composting toilets
RestrictedSeptic approval is controlled by the state (SCDES, formerly DHEC), not the county, but Richland County will not issue a building permit without SCDES septic approval where no public sewer exists. Part of the county is in the Sandhills soil region, which can require enhanced treatment systems. source
Greywater reuse
RestrictedNo Richland County ordinance modifies the state baseline; engineered greywater reuse generally requires a licensed SC engineer's design under state rules.
Rainwater harvesting
Unclear - verifyNo county or state-specific rule on rainwater harvesting caps or registration was found; confirm with county building/zoning before installing a system. source
Private wells & water rights
RestrictedPrivate wells fall under statewide SCDES well standards; no Richland County-specific well ordinance was found. source
Living disconnected from utilities
Varies locallyNo county ordinance bans grid disconnection outright, but occupying a habitable structure still requires zoning compliance, a building permit, and (if applicable) a septic permit. source
