Retaining Wall · San Miguel County, New Mexico
Set by local rules
In New Mexico, there is no single statewide rule for a Retaining Wall; whether you need a permit is decided locally in San Miguel 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 San Miguel Planning & Zoning. Zoning setbacks apply either way.

Walls over a certain height typically require an engineered plan and a building permit.
With a population of around 26,850 residents, San Miguel County generally runs a more streamlined permitting process than major urban hubs.
