In Auburn, building permits come from the city's Building Services team, which handles permits for building construction, additions and alterations. Footings usually go in as part of that kind of work, but whether your job needs its own permit depends on what's being built, so I don't guess. Before we schedule, we confirm whether your address falls under the city or the county, and we handle the application when your job needs one.
Auburn sits in both King and Pierce counties, and the state's soil maps for each county mark where wet, sandy ground loses strength when an earthquake shakes it, and where soil makes the shaking stronger. Peat is shown on its own, because it can shift for good in a quake and the building code calls for a study of that particular site. That's why I'd like to know what's under your house before we size a single footing.
We're based in Auburn and do the same footing work in the cities around it, including Kent and Tacoma. Most of the footing calls we get are for additions, garages, deck posts and garden walls, and some come from property owners planning a business lot.
