Jet City ADU specializes in building accessory dwelling units and detached cottages — new builds and conversions — in the Everett and Snohomish County region. We deliver quality ADU’s and DADU’s on schedule, and with a local crew you’ll know by name.

We build the kind of homes that quietly outlast trends — a place for a tenant, a parent moving closer, a grown child landing, or a backyard cottage that pays for itself.

Run by Matt Matysik, Jet City ADU has spent the last decade focused on a narrow set of project types: accessory dwelling units and DADUs — new builds and conversions — plus additions, new construction, and whole-home renovations. That focus is on purpose. It lets us run a single crew, keep schedules honest, and finish with the attention to detail this work deserves.

The trades who finish your house should be the same ones who started it.

We work with a small set of trades we've known for years — framers, electricians, plumbers, tilesetters — and we plan the schedule around their availability instead of hopping between subs. The result is a quieter site, fewer surprises, and finish work that looks like it was always supposed to be there.
