Thurston County Property Records
Thurston County property records are maintained by the county Assessor, Auditor, and Treasurer, all based in Olympia, the state capital. With about 298,000 residents, Thurston County covers a mix of urban, suburban, and rural parcels in the south Puget Sound region. You can search property records online through the Assessor's property search tool, review deed filings at the Auditor's office, and pay taxes through the Treasurer's portal. This page explains where to find Thurston County property records and how to use each county office's resources.
Thurston County Overview
Thurston County Assessor Property Records
The Thurston County Assessor is responsible for identifying, locating, and fairly valuing all real and personal property in the county for tax purposes. The current Assessor is Steven J. Drew. The primary goal of the office is to find the market value of each property, which means the price a typical buyer would pay in the current market with the property in its present condition. This value drives the property tax levies paid by landowners throughout Thurston County.
The Assessor's website provides access to several key resources. These include tools for the appraisal of residential and commercial property, information on business personal property, property tax relief programs, and levy process details. The site also has publications, forms, and a Property Tax Analysis Tool you can use to review your current value and understand how it compares to recent sales. Under RCW 84.40.020, all assessment records are public and available for inspection.
In 2025, the Assessor mailed change of value notices to owners of residential and commercial properties throughout the county. The notices show the new appraised value used for 2025 taxes. If you received a notice and believe the value is incorrect, you can appeal to the Board of Equalization. The county website has the full appeal process and forms. Under RCW 84.41.030, the assessor must revalue all property on a continuous basis.

The Thurston County Assessor's site gives access to property tax analysis tools, exemption programs, and the online property search for all parcels in the county.
Thurston County Property Search Tool
The Thurston County property search is accessible through the Assessor's website. You can look up parcels by address or parcel number. The search results show assessed values, ownership information, legal descriptions, and property characteristics. This is the primary self-service tool for Thurston County property records and can answer most basic questions about a parcel's tax status and assessed value.
The Assessor's website also mentions a Property Tax Analysis Tool. This tool helps property owners see how their assessment compares to similar properties in the area. It can be useful when deciding whether to appeal your value. All searches on the county's system are for reference only, and the county notes that results may not reflect recent changes.
For older historical records, the Washington State Archives Digital Archives covers Thurston County. Historical real property record cards and other documents are searchable by parcel number or address. These records go back decades and can help with title research or establishing a property's history.
The Thurston County property search portal provides online access to parcel data, assessments, and ownership details for all properties in the county.
Thurston County Auditor and Deed Recording
The Thurston County Auditor records all real property documents in the county. Deeds, mortgages, deeds of trust, liens, and easements are all filed with this office. Under RCW 36.22.010, the auditor is the official recording officer for the county. Documents submitted for recording must meet formatting requirements under RCW 65.04.045 and the proper fee must be paid.
Recording is what makes ownership public. Under RCW 65.08.070, conveyances include any instrument that creates, transfers, or mortgages an interest in real property. A deed or mortgage that is not recorded may be valid between the two parties involved, but it is not effective against a later buyer who records without knowing about the earlier document. When you buy property in Thurston County, you depend on the auditor's records to confirm a clean chain of title.
The Real Estate Excise Tax under RCW 82.45 must be paid before the auditor can record a deed. The Treasurer handles this collection. This requirement links the two offices in any property sale transaction.
The Thurston County Auditor records all deeds, mortgages, and other instruments affecting title to real property in the county, maintaining the official recorded document index.
Thurston County Treasurer Tax Records
The Thurston County Treasurer collects property taxes, manages tax foreclosure proceedings, and handles real estate excise tax collection on property transfers. Property taxes in Thurston County are due in two installments: first half by April 30 and second half by October 31. You can pay online, by mail, or in person at the Treasurer's office. The Treasurer's website has links to the online payment system and details on accepted payment methods.
The Treasurer also maintains records of tax payment history for all parcels. These records are useful when buying property because they confirm whether any taxes are delinquent. If taxes go unpaid long enough, the Treasurer can initiate foreclosure. The county then acquires the property and may offer it for sale. Information on tax foreclosure auctions and tax title properties is available through the Treasurer's office.
Tax records at the Treasurer's office connect to the assessor's parcel data, so you can cross-reference a parcel's assessed value with its tax billing history. The Washington Department of Revenue directory links directly to the Thurston County assessor and treasurer sites for convenience.
The Thurston County Treasurer handles tax billing and collection for all parcels in the county, with online payment options and foreclosure information available on their site.
Property Record Law and Public Access
Thurston County property records are governed by the same Washington State statutes that apply to all 39 counties. Chapter 36.21 RCW sets the assessor's responsibilities. The assessor must value all taxable real and personal property in both city limits and unincorporated areas to make sure taxes are levied fairly. Taxpayers who think their value is wrong can appeal to the county Board of Equalization.
The Public Records Act, Chapter 42.56 RCW, applies to all county offices in Thurston County. Most property records are public. Ownership data, tax information, assessed values, and the recorded document index at the Auditor's office are all available to the public. Some confidential income data submitted with exemption applications may be withheld, but general parcel data is not restricted.
Being the location of the state capitol means Thurston County also has more state-owned property than most counties. State trust lands managed by the Washington Department of Natural Resources are a significant part of the land base. The MRSC county officials guide provides helpful background on how each county office handles property records under Washington law.
