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 rulesBarrow County, GA
Zoning & raw-land occupancy
Varies locallyBarrow County (unincorporated) has countywide zoning under its Unified Development Code, administered by Planning & Community Development, with permitted uses and lot sizes varying by zoning district. Incorporated cities within the county may have separate codes. source
Dwellings, tiny homes & RVs
Unclear - verifySpecific standards for tiny homes, minimum dwelling size, or RV occupancy could not be confirmed on an official Barrow County page; the UDC likely covers this but the exact provisions weren't locatable. Ask Planning & Community Development directly.
Building permits & codes
Generally allowedBarrow County requires permits for structural changes and additions through Planning & Community Development, with state minimum codes as the floor. If served by septic, an Environmental Health approval letter is required with the permit application. source
Septic & composting toilets
Generally allowedSeptic systems are regulated under state DPH rules (on-site sewage management regulations) but permitted locally through Barrow County Environmental Health, part of the Northeast Health District. source
Greywater reuse

Rainwater harvesting
Generally allowedNo Barrow County-specific rainwater harvesting ordinance was found; the state plumbing code appendix and related provisions apply by default.
Private wells & water rights
Generally allowedPrivate wells fall under the state Water Well Standards Act with county health department notification through Barrow County Environmental Health. The county's Water and Sewer Authority may also serve as an alternative provider in some areas.
Living disconnected from utilities
Unclear - verifyNo dedicated Barrow County ordinance on full utility disconnection was found; the permitting process accommodates septic-based (non-sewer) properties, but no explicit rule addresses off-grid power or water disconnection.
