Search Washington Property Records

Property records in Washington are maintained at the county level. The County Assessor handles property valuations and assessment data. The County Treasurer handles tax bills and payments. These are separate offices with separate databases.

What this page covers: Washington property assessment lookups, tax record searches, and parcel/ownership data. What it does not cover: Recorded documents like deeds and mortgages (those are on the Recorded Documents page) or property transfer history.

Where to start: For property values and tax assessments, start with the County Assessor. For tax payment history and bills, go to the County Treasurer. For ownership verification, you may need both the assessment records and the recorded documents.

Common mistake: Property assessment records (values and taxes) and recorded documents (deeds and liens) are maintained by different offices in Washington. The County Assessor handles assessments; the County Auditor handles recordings. Search both if you need the full picture.
