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