Retaining Wall · Malheur County, Oregon
Set by local rules
In Oregon, there is no single statewide rule for a Retaining Wall; whether you need a permit is decided locally in Malheur 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 Oregon leaves this to local jurisdictions, the reliable answer comes from Malheur County building department. Zoning setbacks apply either way.
