New Construction Cost Guide for Isle of Palms, SC

Building on Isle of Palms means building for the ocean environment first — foundation type, elevation, and site work drive cost here more than finishes do.

Foundation and Elevation Requirements Set Your Cost Floor

Coastal construction on the island typically means pilings rather than a slab, and flood zone designation determines required elevation above base flood level. These structural requirements are non-negotiable and should be priced and confirmed with the Building Department before you finalize a design, not discovered mid-permitting.

Permit Review Takes Real Time — Build It Into Your Schedule

The Isle of Palms Building Department states that permit application review can take four to six weeks, on top of the time needed to prepare stamped construction drawings, a scaled survey site plan, and elevation drawings. A DHEC septic permit may also need to run in parallel. Holding costs during this review window are a real, budgetable line item.

Permit Fees Are Tied to Project Value

The town's base permit fee is $60, plus $6 per $1,000 of total project value, with an additional plan submittal fee equal to half the permit fee when construction drawings require review. On a high-value custom build, this is a meaningful line item to budget for, not a rounding error.
