As of Monday, April 29, the Office of the Assessor-Recorder has a new main office phone number, 628-652-8100. For the 12 months following this transition, 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.

Each year the Assessor-Recorder is required by the State of California to value all in-progress new construction. We mail a letter to property owners that have an open permit for new construction as of January 1. This form is for you to tell us what the status of your project is and how much has been completed.

The Assessor-Recorder is required to determine the assessability of all new construction and, if assessable, to value all new construction in progress on each January 1st taxable lien date.

The In Progress New Construction Assessment diagram illustrates the process.
