Beginning on April 16, 2024, the Office of the Assessor-Recorder will transition to a new main office phone number, 628-652-8100. For the next 12 months, constituents who call the Office’s prior phone number will automatically be transferred to our new line. As part of this transition, the Office is instituting key upgrades to improve the experience that San Franciscans have when calling us. To learn more, click here.

The Assessor is required to assess the property at its current market value when a change in ownership occurs.  This usually results in an increase in property taxes.  However, there are some changes in ownership that are excluded from reassessment.
