Glynn County, GA Environmental Rules: Boat Dock Permits (2026)

1(i) of the Glynn County Zoning Ordinance lists private boat docks and boat houses among the uses customarily accessory to a residential dwelling, meaning a homeowner does not need a separate zoning district change to add one. 2(1) separately makes a private, non-commercial dock or boat house a permitted use, by right, in the CP Conservation Preservation District, the zoning classification the county applies to marsh, wetland and other environmentally sensitive water-adjacent land. Both provisions get an exception from Section 610's ordinary accessory-use setback: while sheds, garages and other accessory structures must sit at least five feet from any property line, Section 610 expressly excludes boat houses and boat docks from that five-foot floor, since a dock has to physically reach open water or the marsh edge at the property boundary.

That zoning-level permission does not replace environmental review. Section 618, Environmental Protection, requires all development to satisfy the Georgia Department of Natural Resources Environmental Protection Division and the Glynn County Board of Health, and sets a minimum 15-foot setback along marsh boundaries subject to tidal influence, certified under the Coastal Marshland Protection Act, on top of a vegetated buffer required around freshwater wetlands. 1 requires for construction of any structure in unincorporated Glynn County.
