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

Zoning & raw-land occupancy

RestrictedBeaufort County has full countywide zoning through its Community Development Code, with mapped districts governing land use and setbacks, enforced by County Zoning. source

Dwellings, tiny homes & RVs

RestrictedManufactured/mobile homes need a zoning permit before a placement permit, and are registered by the county Building Codes office; tiny-house-on-wheels/RV occupancy rules are not confirmed, so ask Zoning directly. source

Building permits & codes

Generally allowedThe county Building Codes Office enforces state-mandated building, fire, electrical, and floodplain codes and requires a zoning permit before a building permit. source

Septic & composting toilets

RestrictedSeptic permitting is a state matter handled by SCDES, with the county referring residents there; composting toilets as standalone systems are not confirmed and likely still need SCDES approval. source

Greywater reuse

RestrictedGreywater discharge is regulated by SCDES as a state matter; no county-specific loosening was found. source

Rainwater harvesting

Unclear - verifyNo Beaufort County zoning, building, or health page addresses rainwater catchment or cisterns; confirm directly with County Zoning and Building Codes.

Private wells & water rights

RestrictedPrivate wells are permitted through SCDES at the state level; unincorporated county residents also have the option of connecting to the Beaufort-Jasper Water & Sewer Authority instead of drilling. source

Living disconnected from utilities

Varies locallyNo blanket county ban on off-grid utility living was found, but zoning, building, and either septic/sewer and well/water connection requirements apply to any inhabited structure, per the county's own permit checklist. source
