Retaining Wall · Oglala Lakota County, South Dakota
Set by local rules
In South Dakota, there is no single statewide rule for a Retaining Wall; whether you need a permit is decided locally in Oglala Lakota County.
Most jurisdictions exempt a retaining wall up to 4 feet tall (measured from the bottom of the footing) with no surcharge, following the IRC baseline; over 4 feet, or any wall holding back a slope, driveway, or structure (a surcharge), needs a building permit and engineered drawings. Many cities lower the threshold to 3 feet, concrete or masonry walls often need a permit at a lower height, and tiered walls count as one combined wall. Because South Dakota leaves this to local jurisdictions, the reliable answer comes from Pine Ridge Building Products. Zoning setbacks apply either way.
