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.
