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

Walls over a certain height typically require an engineered plan and a building permit.
With a population of around 80,172 residents, Chelan County generally runs a more streamlined permitting process than major urban hubs.

Frequently Asked Questions
What happens if I build a Retaining Wall without a permit in Chelan County?

Yes. Washington generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Washington State Building Code.
