Does a retaining wall need a permit in Ellensburg?
A retaining wall no more than 4 feet tall, measured from the bottom of the footing to the top of the wall, is on the city's list of work exempt from a building permit. That exemption ends if the wall holds up extra weight above it, like a slope or a driveway, or holds back flammable or combustible liquids. We measure from the footing with you, so you know which side of that line your wall falls on.
