2021-22 Assessment Roll

The Assessor has announced the $57.69 Billion 2021-22 annual Property Assessment Roll which reflects a 4.80% increase in value compared to the prior roll. The real estate part of our economy has made it through the difficult last year in fairly good shape, with the residential market being very strong. The 2021-22 roll valuations reflect 2020 calendar year events and market conditions as of the January 1, 2021 lien date.

Property owners may review their specific 2021-22 assessed value information from this webpage by using the “Services” drop down menu and clicking Assessor Value Notice Inquiry

If you have questions regarding your assessed value(s) you are encouraged to contact the Assessor’s office for an explanation or to request an informal review. If you are unable to resolve your concerns in discussions with the Assessor’s office, you can file a formal Assessment Appeal between July 2 and November 30, 2021, by contacting the Clerk of the Board of Supervisors.

2021-22 roll values have been delivered to the Auditor-Controller's office where tax rates will be applied to the assessed roll values to calculate the tax amounts due. The Treasurer-Tax Collector will send unsecured tax bills in July and will send out secured property tax bills in the fall.

As the elected Assessor of Stanislaus County, it is my sworn responsibility to uphold the State's Property Tax Laws. Our website is an ongoing part of my commitment to keeping you informed of your rights and responsibilities as property owners in Stanislaus County. To contact our office directly please call (209) 525-6461, 8:00 AM to 4:30 PM, Monday through Friday.

Thank you,

About Us

Who We Are

The Assessor is primarily responsible for preparing an annual assessment roll upon which property tax revenues are generated. The County, Public Schools, Cities, Redevelopment Agencies, and Special Districts all rely on this revenue for funding operations.

What We Do

All property, excluding supplies, movable equipment, boats, and aircraft, are assessed based upon their market value when purchased or newly constructed. The Assessor determines the market value for the ownership changes and new construction. The supplies, movable equipment, boats, and aircraft are assessed based upon their annual market value on January 1 of each year. The Assessor also maintains property parcel maps. These maps are available to the public in the Assessor's Office or at the County's web site (GIS Maps Viewer). The property tax assessment roll, property ownership information, and some property characteristics are also available to the public at the Assessor's Office.

What We Offer

The mission of the Stanislaus County Assessor's office is to produce a fair, accurate and timely assessment roll while providing excellent customer service.
Fee-based annual data subscriptions are also available. See "Assessor Services" for more information.
The Assessor's Office is open Monday-Friday, 8:00 am to 4:30 pm.
