What Builders Risk Insurance Requirements Apply in South Carolina?

A South Carolina construction site’s permit needs depend on both disturbed acreage and location; in coastal counties, additional requirements may apply. On a lot beside tidelands, the state may require a certified Critical Area Line for a stormwater permit, so settle the work and laydown footprint before finalizing the project schedule and insurance locations.

What Is Builders Risk Insurance?

Builders risk protects the project you are building, including materials meant for it, against physical loss until construction ends. The gaps that cost owners money are materials in storage or transit, the existing building in a renovation, and coverage ending when you occupy early. Read the national Builders risk guide.

What to Watch for With Builders Risk in South Carolina

Coastal county can change the permit path
SCDES says construction requirements depend on disturbance amount and location, and projects in any of eight coastal counties may face different requirements. Confirm the county and applicable coastal requirements before grading or moving stored project materials onto a prepared site. ¹
A parcel beside tidelands may need a certified line
SCDES requires a current certified Critical Area Line for stormwater permits on lots adjacent to tidelands. The line marks upland from tidelands or coastal waters; work seaward of it may require a critical-area permit. Resolve the boundary before choosing where to excavate, stage, or protect project property. ²
Local boundary and buffer review can reach beyond state permit triggers
Local governments may require a certified Critical Area Line for construction with buffers or setbacks, planning, subdivisions, and transactions. A state permit threshold alone therefore does not settle whether the proposed access, storage pad, or work area is usable. ²
