Do you need a permit for Retaining Wall in Decatur County?
In Tennessee, there is no single statewide rule for a Retaining Wall; whether you need a permit is decided locally in Decatur 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 Tennessee leaves this to local jurisdictions, the reliable answer comes from Decatur County Sheriff Department. Zoning setbacks apply either way.
