A dock is the one part of a coastal Georgia property that the seller may not actually own. It sits over state-owned water bottoms under a state authorization, and the rules governing that authorization are being rewritten right now. If you are buying anything on the marsh in Chatham County this autumn, the timing matters.
Key Takeaways
– A private dock from your own parcel needs a Revocable License from the state, not a marshlands permit.
– Georgia currently has no adopted rules for issuing those licenses. A proposed set is awaiting Board action.
– The federal permit that had set dock standards expired in 2022 and was never renewed.
– A 25-foot buffer runs along coastal marshlands, measured from the jurisdictional determination line.
Who authorizes a private dock?
The state, through its Coastal Resources Division, and the authorization type depends on what the dock serves. The division puts it simply: “If you’re building a dock that originates from a parcel that you own, you must obtain a Revocable License from our office” (Georgia DNR Coastal Resources Division).
Shared structures are a different animal. “If you’re building a community dock or marina that is not intended for single-family private use from a residential lot, you will need to apply for a Coastal Marshlands Protection Act Permit (CMPA).” If you are buying into a neighborhood with a shared dock, you are looking at the second category, not the first.
The word revocable is doing real work. The division describes the instrument as follows: “The Revocable License (RL) authority of the State of Georgia allows for structures to occupy public trust lands water bottoms” (Georgia DNR). The dock structure may belong to the owner. The ground beneath it does not.
What laws are in play?
Two state acts and a buffer rule, each covering different ground. The division explains that “The Coastal Marshlands Protection Act (CMPA) regulates activities and water dependent structures in jurisdictional marshlands,” while “The Shore Protection Act (SPA) regulates activities and structures in jurisdictional beach and shore areas.”
The lists matter when you are planning work. CMPA projects “include marinas, community docks, bridges, dredging, bank stabilizations, modifications to any such structure, and any construction not exempted from the Act.” Shore Protection Act projects “include beach renourishment, rock revetments, landscaping, dune crossovers, any structure in the jurisdictional area and any modification to any such structure.”
Read “bank stabilizations” and “landscaping” twice. Buyers routinely plan erosion work or a cleared view down to the water without realizing either can be a permitted activity.
How close to the marsh can you build?
Twenty-five feet back from the line, and the line is a legal determination rather than where the grass looks like it stops. Georgia’s environmental agency states that “There is established a 25-foot buffer along coastal marshlands, as measured horizontally from the coastal marshland-upland interface (Jurisdictional Determination (JD) Line), as determined in accordance with the ‘Coastal Marshlands Protection Act of 1970′” (Georgia Environmental Protection Division, Buffer Mitigation Guidance).
The practical question for a buyer is whether a jurisdictional determination exists for the parcel, and where it puts the line. On a lot where the buildable area is already tight, 25 feet measured from a line you have not seen can be the difference between the house you are picturing and a much smaller one.
Why is this changing right now?
Because the framework has been informal for four years and the state is closing that gap. The division is blunt about the current position: “Currently, there are no rules for how CRD will issue revocable licenses for private docks that are exempt from other coastal wetland permitting laws like the Coastal Marshlands Protection Act” (Georgia DNR, Private Recreational Dock Rules).
The history explains how that happened. Federal authority over these docks had been delegated to the state: “The Corps delegated their authority over docks to the State through a Programmatic General Permit which established criteria and standards for docks in coastal Georgia. The general permit expired in 2022 and was not renewed by the Corps. Since August 2022, CRD has used a Standard Operating Procedure based on the former federal standards as an interim framework for issuing state licenses.” That arrangement dates back to 1996, when “First Programmatic General Permit issued by Army Corps of Engineers; CRD begins authorizing private docks.”
Now the state is writing proper rules. It “is formalizing standards for private recreational docks over state-owned tidal water bottoms by updating Subject 391-2-1 of DNR rules.”
Where does the rulemaking stand?
At the last step before adoption. The division’s own timeline says the public comment period “began August 26, 2026 and closing at 4:30 p.m. September 30, 2026.” Next comes the decision: “October 27, 2026: CRD will request final action by the Board to adopt rules, anticipated,” followed by “Late 2026: Rules go into effect if approved by the Board.”
So as of this writing, comment has closed and the Board has not yet acted. Anyone buying a dock property between now and the end of the year is buying into a framework that could be replaced within months, if the Board approves. This rulemaking has stalled before: the division’s own timeline records a 2016 proposal that was withdrawn.
What is actually on the table?
Several things a buyer would care about. The division lists its key discussion topics as “Requiring a licensed general contractor for dock construction,” “Clarifying protected-species best practices,” “Easier license transfers,” “Dock builder certification program,” “Dock component sizes and criteria” and “Variance pathways.”
“Easier license transfers” is the line to notice. The fact that making transfers easier is a stated objective tells you transfers are not currently frictionless, which is exactly the assumption a buyer is most likely to make. Do not assume the dock authorization moves with the deed. Ask what authorization exists for that specific structure, what state it is in, and what the transfer process is today.
What should you actually check before you write an offer?
Five things, in this order. Whether a revocable license exists for the dock and is current. Whether the structure as built matches what was authorized, because a dock extended or rebuilt without authorization is a problem you inherit. Whether a jurisdictional determination exists and where the line sits. Whether any planned work, especially bank stabilization or clearing, falls inside a permitted category. And what the adopted rules say, if the Board has acted by the time you are under contract.

Frequently asked questions
Does a dock convey with the property?
The structure and the authorization are different things. A private dock occupies state-owned water bottoms under a revocable license, and the state’s current rulemaking lists “easier license transfers” among its key discussion topics, which indicates transfers are not automatic today. Confirm what authorization exists for the specific dock and how it transfers.
Do I need a marshlands permit for a private dock?
Usually not. Georgia’s Coastal Resources Division says a dock originating from a parcel you own requires a Revocable License from its office, while a community dock or marina not intended for single-family private use from a residential lot requires a Coastal Marshlands Protection Act permit. Which one applies turns on who the dock serves.
How far from the marsh must I stay?
Twenty-five feet. Georgia establishes a 25-foot buffer along coastal marshlands, measured horizontally from the coastal marshland-upland interface, known as the Jurisdictional Determination line, under the Coastal Marshlands Protection Act of 1970. Whether a determination exists for a given parcel is an address-level question worth answering before you offer.
Are Georgia’s dock rules changing?
Yes. The Coastal Resources Division is updating Subject 391-2-1 of the DNR rules to formalize standards for private docks. Public comment closed at 4:30 p.m. on September 30, 2026, and the division anticipates asking the Board of Natural Resources for final adoption on October 27, 2026, with rules taking effect in late 2026 if approved.
Getting this checked for a specific property
None of these questions can be answered from a listing. They are answered by the state’s records for that parcel and that structure, and they are worth answering before an inspection period rather than during one.
