San Francisco Property Valuation - City Law Guide
Property valuation affects taxes, sales, and permits across San Francisco, California. This guide explains how local valuation works, who enforces assessment rules, how values affect your tax bill, and practical steps for owners, buyers, and agents to check or challenge valuations.
How property valuation works in San Francisco
The San Francisco Office of the Assessor-Recorder determines assessed values for real property used to calculate property taxes and special assessments. Assessed values are based on purchase price, new construction, reassessment events, and statutory limitations such as California Proposition 13; local voter-approved measures and special assessments may also change the tax bill. For official details on assessment methodology and timelines, see the Assessor-Recorder resourcesAssessor-Recorder page[1].
When values change
- Annual tax roll publication and assessment dates are set by the county assessment calendar.
- Events that commonly trigger reassessment: changes in ownership, new construction, certain exclusions or exclusions denied.
- Owners receive notification of assessed value changes and have set periods to review or contest assessments.
How assessed value affects your tax bill
San Francisco property tax bills combine the assessed value with the statutory base rate and any voter-approved local assessments or bonds. For payment schedules, bill breakdowns, and collection policies, consult the Treasurer & Tax Collector property tax informationTreasurer & Tax Collector[2].
