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 rulesWashington County, GA
Zoning & raw-land occupancy
Generally allowedWashington County has no countywide zoning ordinance in unincorporated areas, per the county government. Flood-zone and waterway building restrictions still apply, and cities like Sandersville have their own separate zoning. source
Dwellings, tiny homes & RVs
Generally allowedThe county requires a development permit (in place since 2014) for mobile homes, new construction, RV parks, and outbuildings over a certain size in unincorporated areas. Tiny-house-specific rules are not confirmed; check directly with the county. source
Building permits & codes
Generally allowedThe county's development permit system covers construction, driveways, and manufactured housing in unincorporated areas; within city limits like Sandersville, a separate municipal building permit is required for construction and utility systems. source
Septic & composting toilets
Generally allowedSeptic permits for occupied structures are issued by the Washington County Board of Health / Environmental Health under state regulations, with a required site inspection and percolation testing. Composting toilets are not addressed in official sources found. source
Greywater reuse
Generally allowedNo Washington County-specific greywater ordinance was found; this appears to inherit Georgia's state-level baseline rule, unconfirmed to be modified locally.
Rainwater harvesting
Generally allowedNo Washington County or municipal rainwater harvesting rule was found; this appears to inherit the Georgia state plumbing code baseline, unconfirmed to be modified locally.
Private wells & water rights
Generally allowedWells require a permit through Washington County Environmental Health, including a site evaluation, with construction standards set by Georgia's Water Well Standards Act and enforced by the state EPD. source
Living disconnected from utilities
Unclear - verifyNo Washington County or Georgia state source directly addresses full off-grid utility disconnection as its own legal category; septic and well permitting still apply to any habitable structure regardless of grid connection. Not confirmed, ask the county Environmental Health office.
