San Diego County Tax Assessor

The San Diego County Tax Assessor's Office provides essential property valuation and assessment services for all properties within the county. While we're the governmental entity responsible for determining property values, we also assist property owners in understanding their assessments and the appeal process when questions arise. Our role is to ensure fair and equitable property assessments in accordance with California law. We maintain detailed property records, conduct regular revaluations, and provide transparency in our assessment methodologies. When property owners have concerns about their assessments, we offer information and guidance about the formal appeal process through the Assessment Appeals Board.

Our office handles all aspects of property assessment including annual valuations, new construction assessments, and changes in ownership processing. We maintain comprehensive property records and mapping systems. When property owners disagree with assessments, we provide information about the appeals process and assist with understanding assessment methodologies. We process applications for various exemptions including homeowner's exemptions, senior citizen exemptions, and veteran's exemptions. Our staff conducts property inspections when necessary and responds to taxpayer inquiries about assessment procedures. We also handle supplemental assessments for new construction or improvements. Additionally, we provide assessment roll data and property information to authorized users. Our customer service team helps property owners understand their tax bills and assessment notices. We maintain assessment appeal hearing schedules and provide required documentation to the Appeals Board.

Property assessments begin with our annual valuation process where we review all properties in the county using approved assessment methodologies. We use market data, cost approaches, and income approaches as appropriate for different property types. Property owners receive annual assessment notices and have the right to discuss concerns with our staff. If informal discussions don't resolve issues, property owners can file formal appeals with the Assessment Appeals Board. We provide information about appeal procedures and deadlines. Throughout the year, we process change-of-ownership statements and conduct new construction inspections. Our staff is available to answer questions and explain assessment procedures during regular business hours.

We serve all properties within San Diego County boundaries, including 18 incorporated cities and unincorporated areas. Our jurisdiction covers over 4,200 square miles with more than 1.1 million assessed properties. We maintain district offices to serve different geographic areas and provide accessible services to property owners throughout the county.
