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

Zoning & raw-land occupancy

Varies locallyAiken County has countywide zoning through its Land Management Regulations (Chapter 24), administered by Planning & Development, so raw land use is not a free-for-all; unincorporated parcels are subject to district use tables, while the City of Aiken and North Augusta run separate zoning inside their limits. Check your specific parcel's district with Aiken County Planning & Development. source

Dwellings, tiny homes & RVs

RestrictedManufactured/mobile homes must meet SC Manufactured Housing Board habitability standards and county inspection before a Certificate of Occupancy is issued, and a proposed amendment to Chapter 24 to allow tiny homes/RVs conditionally has not been confirmed as finally adopted, so I'd call Planning & Development to check current status before counting on it. source

Building permits & codes

Generally allowedAiken County Planning and Development issues building permits and handles inspections for unincorporated areas, with everything routed through its online Development Services Online Portal; inside the City of Aiken or North Augusta you'd instead go through their own building departments. source

Septic & composting toilets

RestrictedSeptic systems require a permit from the state's SC Department of Environmental Services (successor to DHEC's septic authority), obtained through the local Aiken Environmental Health office, and manufactured home registration requires proof of septic approval; composting toilets aren't addressed at the county level so confirm with SCDES directly.

Greywater reuse

Unclear - verifyNo Aiken County ordinance, form, or guidance on greywater reuse was found, so this defaults entirely to state SCDES rules; not confirmed at the county level, so ask SCDES about engineered greywater reuse requirements.

Rainwater harvesting

Unclear - verifyNo Aiken County ordinance, form, or FAQ on rainwater harvesting, cisterns, or catchment registration turned up in official sources, so this is not confirmed one way or the other at the county level.

Private wells & water rights

RestrictedAiken County sits inside a state-designated Capacity Use Area (created by DHEC in 2018 at the county's own request), and while a typical household well is far below the large-withdrawal permit threshold, all wells still need state well-construction permitting and a licensed SC well driller, plus annual usage reporting for larger users; check with SCDES for specifics. source

Living disconnected from utilities

Varies locallyNo Aiken County ordinance was found mandating grid electrical connection, but obtaining permanent power and a Certificate of Occupancy for a manufactured home is tied to septic approval and county inspection, so those act as practical gatekeepers even for someone planning to go off-grid on electricity. source
