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.

Frequently asked questions

Do you work in Steilacoom?+

How does the Steilacoom historic district affect my project?+
Projects within the historic district require design-review approval from the Town's Historic Preservation Commission before building permits issue. This covers exterior alterations, additions, and new construction visible from a public way. We prepare submittals that address the Commission's criteria, which reduces revision cycles. Not every Steilacoom parcel is in the district — we'll confirm yours.
How long do permits take in Steilacoom?+
Standard permits in Steilacoom's Town permit office generally run 3–5 weeks for plan review. Projects requiring Historic Preservation Commission review add a scheduling cycle — budget an extra 4–6 weeks for that step depending on the Commission's meeting calendar. We account for this in every Steilacoom project timeline.
Can I add a DADU in Steilacoom?+
Yes, HB 1337 applies. Up to two ADUs per lot are allowed in the Urban Growth Area with no owner-occupancy requirement. If the detached cottage would be visible from the street in the historic district, the design will go through Historic Preservation Commission review. We'll plan the design accordingly from the start to make that review as smooth as possible.
