Real Property Assessments

The Assessor's Office is dedicated to ensuring fair and accurate property assessments, which are essential for determining property taxes that fund vital community services. California law requires that property assessments be based on the ownership, possession, or control of the property as of January 1 each year.


Proposition 13

On June 6, 1978, California voters overwhelmingly approved Proposition 13, a property tax limitation initiative. This amendment to California’s Constitution was the taxpayers’ collective response to dramatic increases in property taxes. Prop. 13 rolled back local real estate assessments to 1975 market value levels, limited the property tax rate to 1% (plus the rate necessary to fund local voter-approved bonded indebtedness) and capped future property tax increases at 2%.


Three Approaches to Value

The three major appraisal approaches for estimating value are cost, comparative sales (or sales comparison), and income.

1. The Cost Approach

This method calculates the cost to replace a property, including:

  • Current labor and materials costs

  • Indirect costs like architectural fees, land development, and construction financing

  • Adjustments for depreciation

2. The Income Approach

Used for income-producing properties (e.g., apartments, hotels, business properties), this approach considers:

  • Operating expenses (e.g., maintenance, insurance, taxes)

  • The financial risk involved in generating income

  • Expected return on investment

3. The Sales Approach

  • Commonly used for single-family homes, this method compares the property to similar properties recently sold in the same or nearby areas. It reflects real market conditions by analyzing validated sales data to determine a property’s market value.


Supplemental Assessment

When a property undergoes a reappraisal due to a change in ownership or the completion of new construction, state law requires county assessors to determine a new base year value for the property. Unlike annual tax bills, supplemental assessments are not typically prorated in escrow during the purchasing process, nor are they paid by lenders through impound accounts. Supplemental assessments were established by California Senate Bill 813 in 1983.

  • Supplemental assessments reflect changes in a property’s value for the remainder of the fiscal year (July 1 – June 30).

  • If changes occur between January 1 and May 31, two assessments are issued:

    • One for the current fiscal year

    • One for the following fiscal year

  • Changes between June 1 and December 31 result in a single assessment for the remaining fiscal year.

  • Negative assessments result in a refund issued by the Tax Collector's Office.
