Construction & Remodeling in Steilacoom, WA
Historically sensitive construction and remodeling in Washington's oldest incorporated town.
Steilacoom was incorporated in 1854 — the first incorporated town in Washington Territory — and that history is visible in the built environment. Victorian and craftsman-era homes, a small-town grid laid out before the automobile, and residents who care deeply about what new construction and renovation look like next to their historic neighbors. Work here is not difficult, but it requires knowing what the local review process expects and how to present a project that fits the character of the street.
We've done projects in Steilacoom and are familiar with the historic-district design-review process. If you're planning a remodel, addition, or DADU here, the permit path needs to be handled carefully from the start — and we can walk you through it.

Permits & zoning
Building in Steilacoom
Permit authority in Steilacoom is the Town of Steilacoom. The Town is an incorporated municipality with its own permit office for properties within city limits. Some parcels in the surrounding area on the Steilacoom plateau and adjacent to Fort Steilacoom Park may fall in unincorporated Pierce County, in which case permits route through Pierce County PALS — we confirm your jurisdiction from your parcel number before anything starts.
Steilacoom is a GMA-planning jurisdiction and subject to HB 1337 (RCW 36.70A.680). Two ADUs per lot are allowed in the Urban Growth Area; no owner-occupancy requirement; conversions of existing detached structures must be allowed even where they fall outside current setbacks; impact fees for ADUs are capped at 50% of principal-unit rates. DADU permits typically follow the 4–8 week timeline HB 1337 requires.
Steilacoom has a formally designated historic district covering much of the core residential and commercial area. Projects within the historic district — including additions, new construction, demolition of contributing structures, and exterior alterations visible from a public way — require design review by the Town's Historic Preservation Commission before building permits issue. This is a substantive review that evaluates materials, massing, window proportions, and compatibility with the surrounding historic character. We prepare submittals that address these criteria directly, which reduces the chance of revision requests. If your property is outside the historic district boundaries, standard Town permit review applies without the additional design-review step.
