Real estate in California is assessed in accordance with Proposition 13, which mandates that rate of the general levy be equal to assessed values be at 1% of a property's market value and restricts the increase in assessments to 2% per year. When a property sells in an arm-length transaction, its purchase price is generally considered its market value, and the Assessor will usually use the price to determine the assessment.

When there is a decline in value, Proposition 8 allows the assessor to temporarily lower the assessed value of your property. Proposition 8 requires the Assessor to annually enroll the lesser of a property's Proposition 13 value or its current value.
