Do I need a permit for retaining wall construction in Lexington?
Most likely yes. Retaining wall construction usually requires a permit in South Carolina. Confirm the specifics with Lexington.
South Carolina's statewide code adoption does not include the codes' administrative chapters (S.C. Code Section 6-9-50 and the Building Codes Council's adoption notice). The list of work exempt from a permit is set by each city or county ordinance, so ask your local building office before assuming an exemption applies. The model IRC permit exemption for low retaining walls (not over 4 feet from the bottom of the footing to the top of the wall, with no surcharge) is part of that administrative chapter, so in South Carolina it applies only where your local ordinance adopts it. Always locate underground utilities before digging a footing, and keep the wall and its drainage on your own property. This wall will hold up a driveway, patio, structure or sloped ground, which puts extra load on it (a surcharge). Model code exemptions for short retaining walls specifically exclude walls supporting a surcharge. Surcharged walls commonly need an engineered design, drainage behind the wall, and an inspection, because a failure can undermine whatever sits above it.
