About King County Archives


Government records are essential for increasing government transparency and protecting the rights of citizens. King County Archives holds historically relevant records created by King County government employees, offices, and agencies. Records range from County Council meeting minutes, County Executive orders, photographs, reports, maps, and project files.

Records at Other Agencies

King County Archives holds many county records, but not all of them. We don't hold name change records, divorce decrees, birth and death certificates, and court case files. Visit the Records at Other Agencies page for more information about documents held by other offices and how to access them.

Research Guides

King County Archives created research guides that recommend archival records, additional resources, and search strategies to help you locate information on a specific topic. The Seattle / King County Building History guide was produced by Seattle Public Library in collaboration with the Archives.

2023: New Year, New Look

2022 was a year full of change and transformation for King County Archives. We moved back into our renovated building, moved 8,000 boxes of records back on-site, opened to the public for limited in-person research, welcomed two new Assistant Archivists, and increased access to the recorded documents collection for the Racial Restrictive Covenants Project researchers.

This year, to match our renovated building, we've renovated our website with more information about the records in our holdings and beautiful images of our collections. These images are courtesy of Records Center Technician Matthew S. Browning. In addition to working for King County, Matt is a professional photographer with more than 15 years of experience. He specializes in event, portraiture, and editorial photography, and since 2014, he is a frequent contributing photographer for Real Change Newspaper.

We are thrilled to feature Matt's photos of our historical records and newly renovated space, and we appreciate the teamwork and support of the entire King County Records Center team: Matt, Coley, Patrick, and Scott.
