Functions of the Assessor
The Assessor must discover and inventory all taxable real and personal property in the county and determine a fair and equitable value to be enrolled on the annual assessment roll. These functions are largely dictated by the California Constitution, the Revenue and Taxation Code, and the State Board of Equalization.
In order to complete the annual assessment roll, the Assessor must do the following tasks each year:
- Process all real property transfers and building permits that require reassessment.
- Process all exemption claims including homeowners, veterans, welfare, church, and religious.
- Process all mining claim, boat, aircraft, and business property statements.
- Maintain the integrity of the mandatory audit program by keeping up with the statutory requirement to audit all businesses that have a value of more than $400,000 on a rotational four-year basis.
- Process a variety of claim forms for state and county mandated programs such as the Williamson Act, Disaster Relief, Parent/Child Exclusions, and Base Year Value Transfers.
- Complete all mapping duties and assignment of parcel numbers.
