The Assessor is responsible for determining the assessed value of all taxable property located in San Mateo County. With approximately 236,000 assessments each year, the Assessor's Office creates the official record of taxable property (local assessment roll), shares it with the County Controller and Tax Collector, and makes it publicly available. The local assessment roll is determined by identifying, mapping, inspecting, and calculating the assessed value for all real (land and structures) and business properties. Typically, property tax is 1% of the assessed value, plus an amount to amortize voter-approved bonds, and any fees for special assessments or charges such as mosquito abatement or sewer fees.

 

The Assessor's Office assesses over 217,000 units on the secured roll and 20,000 units on the unsecured roll. In addition, the Office processes approximately 50,000 transfer documents, 24,000 building permits, 143,000 exemptions, and 10,000 business property statements annually.

 

San Mateo County claims within its boundaries a wealth of land, buildings, and taxable property with an assessed value of more than $100 billion. The property tax revenues generated from these assets are vital to maintaining local government operations and public services.
