Message from the Assessor:

As the current elected Assessor of Stanislaus County it is my sworn responsibility to uphold the State's Property Tax Laws. This site is an ongoing part of my commitment to keeping you informed of your rights and responsibilities as property owners in Stanislaus County.

As our economy continues to recover and market values increase, more of you will see your property values stabilize as the assessments are returned to their Proposition 13 values. Under Proposition 13 assessed value increases are limited to a maximum of 2% a year. However, if your assessment is currently reduced to reflect a market value that is less than your Proposition 13 value, then your assessment may be subject to annual increases that exceed this 2% limit. For more information, click on the following link: "About Value Increases."
