Retaining wall construction in South Carolina is governed by the statewide-adopted International Residential Code and International Building Code under SC Code Title 6, Chapter 9, requiring permits and engineering for walls above specified heights.
Under SC Code Section 6-9-50, the IRC and IBC apply uniformly statewide. The IRC generally exempts retaining walls under 4 feet measured from bottom of footing to top of wall and not supporting surcharge loads from permitting. Walls exceeding this threshold or supporting structures, slopes, or driveways require building permits and signed engineering drawings. Local jurisdictions enforce state minimums and cannot adopt weaker standards. Geotechnical considerations, drainage, and frost-depth footings must conform to adopted code provisions. Soil conditions in coastal counties may require additional site-specific engineering.
Building without a required permit may result in stop-work orders, demolition orders, and civil penalties imposed by the local building official enforcing the state-adopted code.
