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 rulesGwinnett County, GA
Zoning & raw-land occupancy
Varies locallyGwinnett County has a countywide Unified Development Ordinance administered by Planning & Development that applies to unincorporated areas; whether raw land can be occupied depends on the parcel's zoning district (e.g., RA-200 Agriculture-Residence). Incorporated cities in Gwinnett have their own separate codes. source
Dwellings, tiny homes & RVs
Unclear - verifyState law leaves RV/THOW siting to local zoning, and RVs built to ANSI A119.2 are meant for recreational/seasonal use, not permanent occupancy. I could not confirm Gwinnett's specific minimum dwelling size or tiny-house/RV occupancy rules from official sources; ask Planning & Zoning directly. source
Building permits & codes
RestrictedGwinnett's Planning & Development department issues building permits, and if you're not on public sewer, Environmental Health must approve septic before a permit is issued; licensed subcontractors must file affidavits before inspections.
Septic & composting toilets
Generally allowedGwinnett Environmental Health (part of the GNR health district) must approve septic tank and drain field design based on bedroom count before a building permit issues, and since 2022 a Level 3 soil report is required for all septic permits. source
Greywater reuse
Unclear - verifyNo Gwinnett-specific greywater ordinance was found; this defaults to the state Department of Public Health baseline. Not confirmed at the county level. source
Rainwater harvesting
Generally allowedPrivate rainwater catchment for non-potable use doesn't appear restricted; the county rule found only bars rainwater/debris from entering the public water distribution system, an infrastructure rule, not a homeowner catchment rule. source
Private wells & water rights
Generally allowedPrivate wells are legal; state rules require a licensed well contractor to notify the county health department before drilling, and Gwinnett's Water Resources department tracks well use, which may exempt properties from certain public-supply lawn-watering restrictions. source
Living disconnected from utilities
Unclear - verifyNo dedicated Gwinnett ordinance on full utility disconnection was found; standard new-home permits do require electrical, HVAC, and plumbing inspections, which complicates but doesn't explicitly forbid going off-grid. Not confirmed as a standalone rule.
