2023/2024 Assessment Roll Announced

Today, Don H. Gaekle, Stanislaus County Assessor announced the 2023-2024 Stanislaus County Regular Assessment Roll total of $65,688,700,362. This is a 6.59% increase over the 2022-2023 roll total. The percentage roll growth for 2023-2024 was broad based with all cities and the unincorporated county exceeding 6% roll growth. The increases result from reassessments for new construction, changes in ownership, annual review of decline in value properties and mandated CPI increases on Proposition 13 base values. The 2023-24 inflation adjustment is the maximum 2.00%. Detailed information can be found in the 2023 Roll Press Release

The County Assessor is mandated to annually establish assessed values for all taxable real property, mobile homes, boats, airplanes and business personal property located within the county. This includes review of properties where the market value may be lower than the property’s Proposition 13 factored base value. The current roll reflects activity occurring during calendar year 2022 and the resulting assessed valuations are effective as of the January 1, 2023, lien date.

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.
