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 rulesGlynn County, GA
Zoning & raw-land occupancy
Varies locallyGlynn County has an adopted, countywide Zoning Ordinance and Subdivision Regulations set by the Board of Commissioners and administered by Planning & Zoning, but the ordinance is in the middle of a full rewrite with drafts released into 2026, so current district standards should be verified directly. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official Glynn County source confirms adoption of the state Tiny House Appendix or a specific policy on RVs as permanent dwellings; ADU standards are being refined in the ongoing rewrite, but that's a separate question. Confirm with Planning & Zoning. source
Building permits & codes
Generally allowedGeorgia mandates International Building Codes as amended by the state Department of Community Affairs, and Glynn County Building Inspections enforces them locally through permits and inspections; Jekyll Island enforces the same state codes through its own chapter. source
Septic & composting toilets
Generally allowedSeptic and onsite sewage systems require a permit through the multi-county Coastal Health District's Environmental Health program, which serves Glynn and several neighboring counties; composting toilets aren't separately addressed and appear to fall under the same rule. source
Greywater reuse
Unclear - verifyNo Glynn County or Coastal Health District page specifically addresses greywater reuse; it appears to default to Georgia's statewide baseline rather than a local ordinance.
Rainwater harvesting
Unclear - verifyNo Glynn County-specific rule on rainwater harvesting was found; presumed governed by the statewide plumbing code, with any local amendments running through Building Code Enforcement. source
Private wells & water rights
Generally allowedWells are permitted and inspected locally by the Coastal Health District's Environmental Health program, layered on top of Georgia's Water Well Standards Act administered statewide by EPD. source
Living disconnected from utilities
Unclear - verifyNo official Glynn County ordinance was found requiring grid utility connection, but building permits require an approved well and septic system before occupancy, which limits full off-grid setups in practice.
