— Our Story
Built by locals, for locals.
NW ADU Builders was formed by a team of Pacific Northwest builders who saw a problem: homeowners wanted to build ADUs, but the process was fragmented, confusing, and full of hidden costs.
We created a one-stop solution — design, permits, and construction under one roof — with transparent, fixed-price contracts. No subcontractor finger-pointing. No surprise change orders. Just honest building.
Since then, we've completed 93+ ADU projects across King, Pierce, and Snohomish counties. We know every permit office, every inspector, and every zoning nuance in the region. That local knowledge is our biggest advantage — and it saves our clients time and money on every build.
