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

Zoning & raw-land occupancy

RestrictedGreenwood County has countywide zoning administered by the joint Greenwood City/County Planning Department, unlike many unzoned rural SC counties. A Rural Development District classification exists for formerly unzoned rural land, with its own setback rules. source

Dwellings, tiny homes & RVs

RestrictedMobile homes are treated as conditional or temporary uses requiring Board of Zoning Appeals oversight, with periodic occupancy review for hardship permits, and are prohibited in flood hazard areas outside existing mobile home parks. No county-specific tiny home ordinance was confirmed. source

Building permits & codes

Generally allowedThe county enforces South Carolina's statewide 2021 building and residential codes with local permitting through the Building & Code Enforcement office, now processed online via CitizenServe. source

Septic & composting toilets

RestrictedNo Greenwood-specific septic ordinance was found beyond the state SCDES (formerly DHEC) requirement; the county will not issue a building permit without prior SCDES septic approval. source

Greywater reuse

RestrictedNo county-specific greywater rule was found; this defaults to the state SCDES framework, which generally requires an engineered reuse system. source

Rainwater harvesting

Unclear - verifyNeither Greenwood County nor SCDES materials specifically address rainwater harvesting caps or cisterns, so confirm directly with the Planning/Building Department before installing a system.

Private wells & water rights

RestrictedPrivate wells are regulated statewide by SCDES under its Well Standards and residential well permitting regulations; no distinct Greenwood County well ordinance or well authority was confirmed. source

Living disconnected from utilities

Varies locallyNo law bans off-grid living outright, but Greenwood's mandatory zoning classification, building permit requirement, and state septic/well approval effectively require permitting before you can occupy a structure disconnected from utilities. source
