Retaining Wall · Valencia County, New Mexico
In New Mexico, there is no single statewide rule for a Retaining Wall; whether you need a permit is decided locally in Valencia 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 New Mexico leaves this to local jurisdictions, the reliable answer comes from Valencia County Building Permit. Zoning setbacks apply either way.
