Beachfront Jurisdictional Area

South Carolina’s beachfront jurisdictional area is made up of three Beachfront critical areas, Beach/Dune System, Beaches, and Coastal Waters, which are defined in South Carolina Code of Laws §48-39-10. SCDES BCM has authority to review activities within all of these critical areas.

Proposed activities within any of the state’s beachfront critical areas should be coordinated with SCDES BCM to determine if authorization is required. Staff are available to assist citizens in understanding the beachfront jurisdiction and the authorization process associated with property-specific activities.

Beachfront Jurisdictional Lines

S.C. Code Ann. § 48-39-280 requires the South Carolina Department of Environmental Services Bureau of Coastal Management (SCDES BCM or Department) to establish and periodically review two beachfront jurisdictional lines, the baseline and the setback line. The baseline is the more seaward (towards the ocean) line, while the setback line is the more landward (towards the land) line. The setback line delineates the landward extent of the state’s direct permitting authority for activities proposed within the Beach/Dune System Critical Area.  

The jurisdictional lines create a state jurisdictional area where activities associated with habitable structures, pools, renourishment, landscaping, fencing, decks, service lines, and other alterations are reviewed to determine if authorization is required to prevent unwise development and to protect resources along the beachfront. Repairs, reconstruction, and new construction of some structures are allowed under certain conditions and with proper notification to the Department as listed under S.C. Code Ann. § 48-39 and S.C. Code Ann. Regs. 30. The jurisdictional lines enable SCDES BCM to implement laws and regulations that support the state's beachfront management goals, and protect vulnerable shorelines, properties, and natural ecosystems. 

Please be aware that there may be critical areas landward of the jurisdictional setback line that may also require authorization and coordination with SCDES BCM. For questions, please reach out to SCDES BCM’s Beachfront Management section at (843) 953-0200, or visit the Project Manager Finder Application to find contact information for SCDES BCM project managers by geographic area.

Jurisdictional Lines Review Process

South Carolina law requires SCDES BCM to establish and review the position of these beachfront jurisdictional lines every 7 to 10 years. The average annual erosion rate for all oceanfront land that is developed or potentially could be developed is also reviewed during this time frame. 

Using historical and present-day shoreline and beach profile information, SCDES BCM designates a baseline and setback line along the coast. The setback line's distance from the baseline is determined by calculating the long-term annual erosion rate in that particular area. The minimum setback distance is 20 feet. 

For additional information about the technical process associated with establishing the lines, please visit our Jurisdictional Lines Review Technical Process page.

Public Education and Engagement

To assist property owners, local governments, and other interested parties in understanding the state’s jurisdictional line review process, beachfront critical areas, and authorization requirements, SCDES BCM has developed a Beachfront Educational Campaign. This effort will utilize a variety of methods to reach a broad and diverse audience including digital products, print materials, social media, as well as in-person and virtual information sharing opportunities.

Appeal Process

Per Act 146, signed on May 15, 2026 (H.4189) 

Section 48-39-280(F) of the S.C. Code is amended to read: 
(F)(1) A landowner claiming ownership of property adversely affected by the establishment of a baseline or setback line, upon submittal of substantiating evidence, must be granted a review of the baseline or setback line. Alternatively, the municipality or county in which the property is situated, acting on behalf of the landowner with his written authorization, or an organization acting on behalf of the landowner with his written authorization, upon submittal of substantiating evidence, must be granted a review of the baseline and setback line. A review is initiated by filing a request with the Division of Coastal Management via certified mail within one year of the establishment of the baseline or setback line and must include a one hundred-dollar-review fee per property. (2) The landowner or the county, municipality, or organization acting on behalf of the landowner may file a request with the Administrative Law Court, in accordance with Chapter 23, Title 1, for a contested case hearing within thirty calendar days after the Division of Coastal Management issues the final agency decision resulting from the review.

Pursuant to Section 48-39-280(F)(1), any landowner claiming ownership of property adversely affected by the establishment of a baseline or setback line may request a review of the line locations from the Bureau of Coastal Management. Alternatively, the municipality or county in which the property is situated, or an organization acting on behalf of the landowner, all with the landowner’s written authorization, upon submittal of substantiating evidence, must be granted a review of the baseline and setback line. Requests must be made within one year of the establishment of the baseline or setback line via certified mail to: 

SC Department of Environmental Services 
Bureau of Coastal Management
1362 McMillan Ave, Ste 400 
North Charleston, SC 29405 

These requests must be accompanied by a $100 fee per property and substantiating evidence to support the claim of the adverse affect of the established baseline and setback line. The substantiating evidence may include data, photographs, or other evidence which could be considered under the guidance of Section 48-39-280(A) and Coastal Division Regulations R.30-14(E) and R.30-21(H) for the establishment of the baseline and setback line.
