Researching Recorded Documents

You do not need an appointment to visit the Archives during lobby hours to research recorded documents. The lobby is equipped with microfilm readers/scanners for self-service research of recorded documents.

The recorded documents collection consists of property ownership records such as deeds, easements, surveys, short plats, and mortgages. We hold recorded documents from 1853 to July 31, 1991, which are available on microfilm only.

Researching Other Records

For other types of records, the Archives research room is open by appointment only.

Please contact the Archives at least 48 hours in advance to access archival records other than recorded documents. This gives our staff time to identify and retrieve records that are most responsive to your research topic.

Construction near the archives building

If you are planning a trip to the King County Archives, please be aware that there is construction on either side of the Archives building, so you may have a bit of trouble finding us. Please look for the building with the graffiti art on it. If a construction worker stops you because part of the street is closed, just let them know that you're visiting the Archives.
