Welcome
Welcome to the website of the Tuolumne County Assessor-Recorder-Archives. Our mission is to provide concise, accurate information regarding the services available from our three divisions. Please check out the pages that are of interest to you and let us know if you have any questions about any of the topics on those pages. As always, we are available during regular office hours to answer any of your questions, but we hope that our new website will make it easier for you to find out about any of our functions. To see our most recent statistics for the assessment and recording divisions, please click on the link on the right-hand side of this page to view our Annual Report.

The State Board of Equalization has developed a video designed to provide information to taxpayers regarding the appeal process. The video is entitled "Your Assessment Appeal" and was developed as a collaborative effort between the Taxpayers' Rights Advocates Office and the County-Assessed Properties division of the State Board of Equalization. Additionally, assistance and input was provided by many of the counties. The video is divided into segments that can be viewed by clicking on the button below or the link on the right side of this page.
We hope that our website will be a constantly changing and improving method of providing access to all. If you have any suggestions for improving our site, please feel free to contact any one of our three divisions.
Thank You!
