Docks and Permits

Every waterfront property in this market touches at least three governments before a dock gets built, and often a fourth. The Georgia Department of Natural Resources Coastal Resources Division licenses the structure itself, since it sits on state-owned tidal water bottom. The U.S. Army Corps of Engineers, Savannah District, reviews it separately under federal navigable-waters authority. Your county adds its own buffer and zoning rules on top of both. And if the lot sits in a mapped flood zone, FEMA's rules follow the house, not just the dock. None of these four talk to each other automatically. That is the part worth understanding first, more than any single rule in isolation.

Who actually qualifies for a dock

The state piece is a Revocable License from Georgia DNR's Coastal Resources Division, which the agency's own marsh and shore permitting page (opens in a new tab) describes as authorization for a private structure to occupy public trust water bottom, and one that can be withdrawn if the owner stops meeting the conditions it was issued under. It is issued alongside CRD's Individual Permit process, which CRD's own authorization page (opens in a new tab) states is required for private recreational docks, submitted to both CRD and the Corps' Savannah District office at the same time. A shared dock serving more than four waterfront residents, or any non-waterfront residents, is routed through the separate Coastal Marshlands Protection Act process instead, the same page notes, which is a longer review built for marina- and community-scale projects, not a single-family dock.

Eligibility itself comes down to the lot. Georgia Conservancy, a conservation nonprofit that has tracked this process closely through the current rulemaking, states in its FAQ on private docks in Georgia's coastal marshes (opens in a new tab) that a qualifying lot generally needs at least 50 feet of marsh frontage plus upland suitable for a single-family home where building is not otherwise prohibited. That is Georgia Conservancy's description of the standard, not DNR's own published rule text, so I am flagging the figure rather than stating it as settled. What is well documented is that the old joint federal-state permit expired in 2022, the same FAQ notes, so today's applicant needs the state license and the federal authorization as two separate steps, not one combined form the way it worked before.

The size of a dock you can build is changing this fall

This is worth knowing before you write an offer with dock plans in mind. Georgia DNR CRD is in the middle of formally writing its private dock standards into rule for the first time since the 2022 federal permit expiration, and the numbers have moved during the process. CRD's own announcement of the draft rules (opens in a new tab) describes it as codifying the standards the agency has already been using informally, plus a new formal variance process. Georgia Public Broadcasting's reporting on the current draft, published September 11, 2026 (opens in a new tab), puts the current proposal at a 1,500-foot walkway, 6 feet wide, with a variance allowance up to 1,650 feet, up from an earlier June 2026 draft of 1,000 feet and well above the old informal cap of 3,000 total square feet. That same reporting notes 84 of 103 public comments opposed the larger size as excessive. Public comment closes September 30, 2026, and the Board of Natural Resources is expected to vote on final adoption October 27, 2026. Whatever number is true when you read this, it will be more current than what I could write here, so check CRD's own notice page (opens in a new tab) directly before you plan a dock around a specific length.

The federal layer

Alongside the state license, the Corps' Savannah District reviews the same structure under Section 10 of the Rivers and Harbors Act, since it sits in a navigable water of the United States. Straightforward single-family docks in the eleven coastal counties are typically handled through a Corps general or regional permit process rather than a full individual permit, but which track applies is a project-specific determination the Corps makes, not something to assume from a neighbor's experience. The Savannah District Regulatory Division's own permitting pages (opens in a new tab) lay out the current permit types. I would rather send you there directly than guess at which one fits a lot I have not seen.

What the county adds

In unincorporated Chatham County, the zoning ordinance's Environmental Overlay District sets a 35-foot riparian buffer measured from DNR's jurisdictional marsh line, and I read the actual ordinance text rather than a summary of it. Section 4-12(f) of Chatham County's zoning ordinance (opens in a new tab) states the buffer "must remain undisturbed at all times," but the same section carves out an exception that matters here: "the minimum building setback from the marsh line shall not apply to any type of marina, commercial marine use, or docking facility." A dock is expected to cross the buffer, since that is the entire point of a dock. What the buffer restricts is the house and other structures behind it, not the walkway out to the water. The Environmental Overlay District also only applies to parcels within its mapped boundary, the Islands and Southeast communities specifically, so whether it touches your lot at all is a question for Chatham County Planning and Development, not something to assume from the address.

Bryan County, which covers the Ogeechee River side of this market, publishes its ordinances through the same Municode system the other coastal counties use, but I was not able to locate a specific published marsh or dock setback figure the way I could for Chatham. Treat Bryan County's shoreline setback rules as unconfirmed until you have them in writing from Bryan County Community Development (opens in a new tab). This is a real example of the parcel-by-parcel rule, not a gap in my research. Two counties inside the same market genuinely publish this information differently.

Flood zone and elevation, even for a dry lot

A dock decision does not happen in isolation from the house's flood status, because both come out of the same site review. Chatham County's Department of Engineering explains its flood zones plainly (opens in a new tab): Zone X is low risk, Zone AE and VE are high risk with a published Base Flood Elevation, and new construction in unincorporated Chatham must be elevated three feet above that BFE. An Elevation Certificate records the actual finished-floor elevation against that number and is what your insurer uses to rate the policy, not a guess. You can request one for a specific parcel free from the county's Floodplain Administrator, or look up the underlying flood map yourself at FEMA's Flood Map Service Center (opens in a new tab), the official public source for these maps. I would do this before writing an offer on anything close to the marsh, not after.

What if the dock is already there

If the property you are considering already has a dock, the question changes. It is no longer whether the state will license one, but whether the one already there has the paperwork to back it up, and that deserves its own answer.

Whether the Revocable License itself passes to you automatically at closing is not clearly spelled out anywhere I could find in plain language. What I can point to is the actual license paperwork. I read GA DNR CRD's own Revocable License Request form (opens in a new tab) directly: it requires "a copy of the Deed and Plat of the subject parcel," states "the applicant must be the current owner," and the license itself is granted to a named applicant, not to the parcel in the abstract. The related Private Dock Construction Notification Form has the signer certify "I am the current owner of the project property." None of that is the same as an explicit transfer rule, so treat whether the license needs to be formally reissued in a new owner's name as an open question, not a settled one, and ask CRD's coastal permit coordinator directly rather than assume the paperwork simply carries over with the deed.

What the same license document does make explicit is the maintenance condition attached to it: the licensed dock "must be maintained in serviceable condition," and if it is not, "action will be initiated to revoke this license and all structures must be removed immediately at the licensee's expense." Ordinary repair and upkeep is not optional under an existing license, it is one of the conditions that keeps the license valid. Where the line falls between routine repair and a change big enough to need a new or modified application is not something this page can state precisely, since the old general permit and the Individual Permit process are meant for different scales of work, and I would confirm any specific repair or rebuild with CRD before assuming it is covered.

Buying a property with a dock that was never licensed at all, or one that was built larger or differently than what is on file, is a real exposure, not a hypothetical one. GA DNR's own Compliance and Enforcement page (opens in a new tab) states its Compliance and Enforcement Unit investigates alleged violations that include "placement of an unauthorized structure," and that "corrective action is taken to bring the facility or structure into compliance," which can mean a retroactive application, a forced modification, or removal at the owner's expense, and once you own it, that cost is yours, not the prior owner's. Before closing, ask the seller directly whether the dock has a current license and permit on file, request copies, and compare the built structure against what those documents describe. You can also search CRD's own Coastal Permitting Database (opens in a new tab) yourself, by address or by map, to see what the state has on record for the parcel. A dock that looks fine from the water is not the same thing as a dock that is fine on paper.

The honest counterpoint

A marsh view is not the same thing as a marsh dock. A lot with a wide water view can still fail on any of three counts: the buildable upland can sit well back from the DNR-jurisdictional line, the marsh in front can be too far from a channel to reach with any reasonable walkway, or the lot may not carry the frontage a revocable license requires. None of that shows up in listing photos. A wide, pretty marsh view can be the exact same feature that keeps a boat off the property forever. The way to find out is not to hope during due diligence, it is to ask CRD directly, before you write the offer, whether the specific parcel is dock-eligible. That is a phone call and sometimes a site visit, not a guess from the plat.

The practical sequence

Before you write an offer: find out whether the lot already carries a permitted dock and a revocable license, or whether one has never been applied for. Ask the seller for the DNR revocable license or permit documents, any Corps correspondence, the Elevation Certificate if one exists, and a current survey showing the marsh line. If any of those are missing and a dock matters to your decision, that is a reason to request a jurisdictional determination from CRD's coastal permit coordinator before closing, not after.

A new dock application itself is a dual submission: the state Individual Permit and revocable license application to CRD, and a parallel federal review from the Corps' Savannah District, built around a current survey and a dock plan drawing. I do not have a reliable current figure for the application fee or the typical review timeline, and this page will not invent one. Both change, and both are worth asking CRD's coastal permit coordinator about directly for your specific lot before you count on a dock being usable by a particular season.
