publicly researched providers
Publicly sourced · organic order is not soldView provider listHow to use this guide
Start with a recognizable place.
Seattle has the directory’s largest concentration of publicly identified offices, so it appears first. The rest of the guide uses recognizable cities and statewide regions instead of expecting visitors to know informal labels such as North Sound or South Sound.
These groups describe published office locations or a published statewide or remote base—not a verified project territory. A nearby office can be a useful starting point, but ask each provider whether it serves the building’s exact city or county and whether travel affects price or scheduling.
Office locations
Seattle first, then the rest of Washington.
Each label includes recognizable cities or a statewide region. A provider may appear more than once when its public office description names multiple locations.
Bellevue / Redmond (Eastside)
Bellevue and Redmond offices east of Lake Washington.
Renton / Kent (South King County)
Renton, SeaTac, Kent, and Tukwila offices south and southeast of Seattle.
Everett / North Puget Sound
Everett, Mukilteo, Snohomish, and Burlington offices north of Seattle.
Tacoma / South Puget Sound
Tacoma, Fife, and Lacey offices in Pierce and Thurston counties.
Southwest Washington
Southwest Washington offices, including South Bend.
Central Washington
Yakima and other publicly identified Central Washington offices.
Eastern Washington
Spokane, Richland, and Tri-Cities offices.
Statewide / remote
Providers publishing a statewide, regional, national, or remote base rather than one nearby office.

Before hiring
Questions worth asking every finalist.
- Which office would serve the project, and where would the assigned team travel from?
- Does the provider regularly work in the building’s city or county?
- Are travel time, ferry costs, or remote work assumptions included in the fee?
- Which tasks require an on-site visit, and which can be completed remotely?
