South Carolina dock permitting, for Hilton Head homeowners
Whether your job is repair or replacement decides the schedule and the paperwork. These guides explain where that line falls and what each side of it requires — and who assembles the package once you know.
Who handles the dock permit package on Hilton Head Island?
Hilton Head Marine Construction prepares and carries the dock permit package across Hilton Head Island and Bluffton — the drawings, the SCDES Critical Area application, the U.S. Army Corps of Engineers notification under SAC-RGP-09, and the architectural review or property owners' association submission a gated community requires alongside it. Call (843) 508-5850. SCDES and the Charleston District decide the applications; what a contractor carries is the preparation, the determination, and the permitted work itself.

What the dock permit package contains, and who carries each part
A Hilton Head dock job runs on three approval tracks at once, not one queue. Running them one after another is the single most common way a project loses a season. We prepare the state and federal submissions and the community's architectural review submission together, because a review condition on one side sometimes changes what the drawings on the other side have to show.
Community architectural review
ASC, ARB, or POA — the community's own committee
Any dock, lift, or bulkhead work inside a plantation or gated community.
- The community's own application forms, at their current revision.
- Site plan and elevations at the detail that committee asks for, which is not always the detail SCDES asks for.
- Submission timed against the committee's meeting calendar, so community review runs alongside state review rather than after it.
Forms, fees, and meeting dates are each community's own and change on its calendar — confirm current ones with that community's office directly.
SCDES Critical Area
S.C. Department of Environmental Services, Bureau of Coastal Management
All dock, bulkhead, and revetment work in South Carolina's tidelands and coastal waters.
- The category determination first: Normal Maintenance and Repair, a general permit, or an individual permit for minor activities.
- Drawings to the standard the category requires — professional-stamped where a Minor Activities permit applies.
- Affidavit of ownership, adjoining-owner notification, and the newspaper public notice with its notarized affidavit of publication where the permit type calls for one.
SCDES decides the application. A contractor prepares it — accurately enough that it goes on notice rather than coming back.
USACE federal authorization
U.S. Army Corps of Engineers, Charleston District
Dock work in federally regulated navigable waters, under regional general permit SAC-RGP-09.
- Pre-construction notification to the Charleston District, filed alongside the state application rather than after it.
- Confirmation that the project sits inside SAC-RGP-09's terms — private, non-commercial piers, floating docks, lifts, mooring piles, minor dredging.
- The district's written verification in hand before construction begins.
SAC-RGP-09 is a five-year regional permit, effective December 2021 and set to expire December 2026 — worth confirming a project's federal authorization is current rather than assuming the same terms hold.
Hilton Head Marine Construction is a marine contractor, not a government agency. SCDES and the Charleston District decide the applications; what we carry is the assessment, the category determination, the package itself, and the permitted work once it is authorized. Hilton Head Marine Construction is South Carolina licensed and insured.
The permit decision matrix
What kind of work triggers what kind of review. Two agencies decide that: the South Carolina Department of Environmental Services (SCDES), which permits construction in the state's tidelands and coastal waters, and the U.S. Army Corps of Engineers' Charleston District, which authorizes dock work in Hilton Head's federally regulated waters under a permit called SAC-RGP-09. Every classification below is checked directly against both agencies. SCDES uses a qualitative standard rather than a fixed percentage: a structure counts as repair while it stays generally intact, functional, and within its original dimensions.
| Work | SCDES Critical Area | USACE SAC-RGP-09 | Note |
|---|---|---|---|
| In-kind repair, same footprint | No permit, no fee — Normal Maintenance & Repair, provided the dock stays generally intact and functional. | Covered under SAC-RGP-09's standing authorization for repair of an existing structure. | The common case for decking and fastener work. |
| Piling replacement, same location and count | No permit, no fee — same Normal Maintenance & Repair standard, since placement and count don't change. | Covered under SAC-RGP-09 as repair, not reconstruction. | Turns on whether the dock overall is still generally intact, not on piling count alone. |
| Reconstruction of a dock that's still generally intact | GP-25-DR reconstruction general permit — $250 fee, 18-month validity, certified-mail and newspaper notice to neighbors required. | Pre-construction notification to the Charleston District required; written verification needed before work begins. | SCDES sets no percentage threshold — this applies once repair exceeds routine maintenance but the dock is still generally intact. |
| Any change to footprint, length, or configuration | Individual Critical Area Permit for Minor Activities — $250 fee ($150 for walkways under 100 ft), professional-stamped drawings, 15-day public notice. | Pre-construction notification required; work outside SAC-RGP-09's terms is referred to individual Department of the Army permit review. | Includes adding a floater, extending a walkway, or any dock larger than what was there before. |
| Emergency stabilization or rebuild after a storm | No-fee Emergency General Permit, available after a declared emergency (S.C. Code §48-39-10(U)) — restores the structure only to its exact prior size, configuration, and location. | Coordinated with the Charleston District alongside the state's emergency permit; federal authorization still applies. | A faster, no-fee lane for restoring what was already there — not a bypass of the permit process. |

What each permit lane waits on
The category determination is the first thing that happens because it is what sets the calendar. These are the Department's own published notice periods and permit terms, not an estimate of how quickly an application will be reviewed — that part is SCDES's to decide, and no contractor expedites it.
| Permit lane | How long | Whose clock | What sets it |
|---|---|---|---|
| Normal Maintenance and Repair | Work can start within days of the determination | Ours | No application and no fee, provided the dock is previously permitted or grandfathered, still generally intact and functional, and the work stays within its original dimensions. What takes the days is scheduling a crew and a tide, not a review. |
| GP-03-001 — minor dock additions | A general permit, with no public-notice period to clear | The Department's | Catwalks to a lift, mooring piles, handrails, and similar additions to an existing, previously permitted or grandfathered dock. Considerably faster than individual review because the terms are pre-approved and narrow. |
| GP-25-DR — reconstruction of an intact dock | Certified-mail neighbour notice and a newspaper public notice each run their own clock; the permit itself is valid 18 months once issued | The Department's | For a dock that is still generally intact and functional but needs more than routine repair. The 18 months are the window to get the work done in, not the wait to start it. |
| Individual Critical Area Permit for Minor Activities | The 15-day public notice alone adds two to three weeks before the rest of review begins | The Department's | New dock construction, or any change to footprint, length, or configuration. Professional-stamped drawings and a notarized affidavit of ownership go in with the application, and the applicant's newspaper notice runs within 15 days of the Department's own. |
| Emergency General Permit | The fastest lane there is — and it still requires an application and Department approval before a rebuild is authorized | The Department's | Available after a declared emergency, and scoped to restoring a previously permitted or grandfathered structure to its exact prior size, configuration, and location. Temporary stabilization that prevents further loss does not wait on it; permanent rebuilding does. |
| USACE authorization under SAC-RGP-09 | Runs alongside the state application, not after it | The Charleston District's | Pre-construction notification is filed with the state package, and the district's written verification has to be in hand before construction begins. Work outside the regional permit's terms goes to individual Department of the Army review instead. |
| Community architectural review | The committee's own meeting calendar | Your community's | A third track, required alongside state and federal review rather than instead of it. Forms, fees, and meeting dates are each community's own — confirm current ones with that community's office directly. |
Nothing here is a promised processing time. Notice periods and permit terms are the Department's own and are published by it; what a contractor controls is which lane the job is correctly in and how complete the file is when it goes in. Confirm current requirements with SCDES and the Charleston District.

Where these rules come from
SCDES writes and administers the state rule; the Charleston District authorizes the federal side. Every category, fee, and notice period stated on this page is checked against these directly — read them at the source rather than taking a contractor's summary for it, this page included.
- SCDES — Critical Area Permitting
The permit categories themselves: General, Minor Activities, Major Activities, and Emergency General.
- SCDES — Normal Maintenance & Repair
The no-permit repair standard: previously permitted or grandfathered, still generally intact and functional, original dimensions only.
- SCDES — General Permits
GP-03-001 dock additions and GP-25-DR dock reconstruction, with their fees, validity, and neighbour and newspaper notice requirements.
- SCDES — Minor Activities
The individual permit path for new dock construction: fees, the professional-drawing requirement, and the 15-day public notice.
- SCDES — Emergency General Permits
The no-fee post-declared-emergency category, limited to the structure's prior permitted or grandfathered condition.
- S.C. Code Regs. 30-12 (LII mirror)
Specific project standards for tidelands and coastal waters: dock size by creek width, setbacks, lot eligibility, and the five-year rebuild window.
- USACE Charleston District — SAC-RGP-09
The federal regional general permit for private docks in SC navigable waters, and its pre-construction notification requirement.
Where the guides go next
The determination is the part worth getting right first, because it decides the fee, the paperwork, and the calendar all at once — and because an unnecessary application and an unauthorized rebuild are both expensive, in opposite directions.
Nothing on this page is legal advice. Confirm current requirements with SCDES and the Charleston District, and confirm community forms, fees, and meeting dates with your own community's office.
Dock permit package FAQ
Do I need a permit to repair a dock in South Carolina?
Often not. SCDES treats in-kind repair of a previously permitted or grandfathered dock as Normal Maintenance and Repair — no permit and no fee — provided the structure is still generally intact and functional and the work stays within its original dimensions. There is no percentage threshold; the test is qualitative. Once the work exceeds that standard, or changes the footprint at all, a general or individual Critical Area permit applies instead.
Who files the dock permit in South Carolina — the homeowner or the contractor?
Either can assemble it, and the owner signs: a Minor Activities permit requires a notarized affidavit of ownership regardless of who prepared the paperwork. What Hilton Head Marine Construction carries is the preparation — the category determination, the drawings, the adjoining-owner notification, and the newspaper public notice where the permit type requires one — so the owner signs a finished package rather than building one. SCDES decides the application. Hilton Head Marine Construction is South Carolina licensed and insured.
Do you prepare the drawings for a SCDES dock permit?
Yes. An Individual Critical Area Permit for Minor Activities requires professional-stamped drawings, and SCDES returns hand-drawn or inexact plans rather than putting them on public notice — which makes the drawing the part of the package that most often decides the calendar. The GP-25-DR reconstruction path is assembled the same way, with its certified-mail neighbour notice and its newspaper affidavit of publication.
Do you handle the POA or architectural review submission as well as the state permit?
Yes. Sea Pines, Wexford, Long Cove, Windmill Harbour, Hilton Head Plantation, Port Royal Plantation, Indigo Run, Palmetto Bay, and the Bluffton communities each run an architectural review or property owners' association process for dock work, separate from SCDES review and required alongside it. We prepare that submission with the state package, because a review condition sometimes changes what the state drawings have to show. Confirm current forms, fees, and meeting dates with your own community's office — those run on each community's calendar, not ours.
How much does a dock permit cost in South Carolina?
The fee follows the category. Normal Maintenance and Repair carries no fee. GP-03-001, the minor dock additions general permit, is $100. GP-25-DR, the reconstruction general permit, is $250 and runs 18 months. An Individual Critical Area Permit for Minor Activities is $250, or $150 where the dock's walkway is under 100 feet. An Emergency General Permit after a declared emergency carries no fee. Those are the Department's fees, separate from what preparing the application costs.
How long does dock permitting take on Hilton Head Island?
It depends which lane the job is in, which is why the determination comes first. Normal Maintenance and Repair work can often start within days of the determination. A Minor Activities permit's 15-day public notice alone adds two to three weeks before the rest of review begins, and GP-25-DR's certified-mail and newspaper notice runs its own clock. Inside a gated community the architectural review calendar is a third schedule to plan against, and federal verification under SAC-RGP-09 has to be in hand before construction begins.
Do I need a permit to replace dock pilings in South Carolina?
Replacing pilings in the same locations and the same count generally reads as Normal Maintenance and Repair — no permit, no fee — because neither placement nor dimensions change. What moves the job out of that category is the condition of the dock overall, not the piling count: once the structure is no longer generally intact and functional, the work is reconstruction and GP-25-DR or an individual permit applies. Cumulative repair counts here too, since pilings replaced a section at a time over several years add up.
Can you tell me which permit my job needs before I commit to anything?
Yes — the category determination happens before a quote is written, not after. It is built from the dock's original permit where one exists, a written description of the proposed work, and dated photographs of the structure's current condition. Older docks on the island sometimes predate readily searchable records, and locating that original approval, or establishing grandfathered status where none was ever issued, is often the first real step. Call Hilton Head Marine Construction at (843) 508-5850.
