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 rulesBryan County, GA
Zoning & raw-land occupancy
RestrictedBryan County has a countywide Unified Development Ordinance (UDO), administered by the Community Development Department, governing land use, lot occupancy, and accessory structures. This differs from Georgia counties with no zoning at all. source
Dwellings, tiny homes & RVs
Varies locallyCompact homes, ADUs, and RVs are reviewed case-by-case against zoning district standards and the UDO; a claimed size-percentage cap for accessory dwellings comes from a non-official real estate source and is not confirmed. Confirm specifics with Community Development. source
Building permits & codes
RestrictedBryan County enforces the International Building Code and International Residential Code (2024 editions with Georgia Amendments, effective January 1, 2026) through its Building and Codes Division. Permits are required for most structures, including fences over seven feet and buildings over 200 square feet. source
Septic & composting toilets
Generally allowedSeptic systems are permitted and administered by the Georgia Coastal Health District's Environmental Health program, not the county directly; a building permit can be applied for before septic approval but won't be issued until Public Health notifies Community Development. Composting toilets are not separately addressed in any official county or district source found. source
Greywater reuse
Generally allowedNo Bryan County-specific greywater ordinance was found; the state standard under Georgia law applies by default. Not confirmed whether the county has added local restrictions.
Rainwater harvesting
Generally allowedNo Bryan County-specific rainwater harvesting ordinance was found; state plumbing code appendix standards apply as the baseline. Confirm any UDO stormwater provisions with Community Development.
Private wells & water rights
Generally allowedPrivate wells are governed by Georgia's statewide Water Well Standards Act rather than a Bryan County-specific ordinance, with notification generally routed through the Coastal Health District's environmental health office. source
Living disconnected from utilities
Unclear - verifyNo official Bryan County page directly addresses full disconnection from water, sewer, or electric utilities; the building code's Certificate of Occupancy requirement implies some water supply and sewage disposal method is needed. Ask Community Development directly about going fully off-grid.
