The content on the Thurston County website is currently provided in English. We are providing the “Translation” for approximately 10 languages. The goal of the translation is to provide visitors with limited English proficiency to access information on the website in other languages. The translations do not translate all types of documents, and it may not give you an exact translation all the time. The translations are made through an automated process, which may not result in accurate or precise translations, particularly of technical and legal terminology.


The Thurston County Assessor, Steven J. Drew, is responsible for identifying, locating, and fairly valuing all real or personal property within the county for tax purposes. The "market" value of real property is based on the current real estate market. Finding the "market" value of your property means discovering the price most people would pay for your property in its current condition. Determining a fair and equitable value is the primary role of this office in the taxing process.

2024 Value Change Notice

Due to staffing shortages, this year’s revaluation notices will not be mailed out until late August early September. 

2023 Value Change Notices Mailed June 2

 The following is an image of this year's value change notice mailed to the owners of residential and commercial properties throughout Thurston County. 

By law, values are calculated as of January 1 and this year's notice reflects the change in value between 1/1/2022 and 1/1/2023.

Over the next several weeks you will likely see news coverage about values in King, Snohomish and Pierce Counties. Last year many of the values in these urban counties increases by over 40% and this year values in many of these counties will decrease by as much as 20%. Here in Thurston our values increased by a much lower percentage last year, and this year on January 1 we saw increases mostly in single digits. So please consider these regional differences as you review your property's value change notice.

In 2014, our office was one of 26 jurisdictions out of 13,000 assessment jurisdictions in the United States to be awarded the Certificate of Excellence in Assessment Administration (CEAA) by the International Association of Assessor Officials (IAAO).

This certificate recognizes our outstanding achievement of meeting the requirements for the CEAA, exceeding the guidelines as established for this award by the IAAO in property assessment administration practices.

In 2020, our office received a recertification from the IAAO, demonstrating our ongoing commitment to maintaining these high standards in assessing property, assuring that we are doing as much as we can to achieve fairness and equity in the property tax system.
