Why Assessed Value May Increase More Than 2%

By law, the Assessor must annually enroll either a property’s Prop 13 value (factored for inflation by no more than 2% annually), or its current market value on the lien date (January 1), whichever is less. When a property’s current market value falls below the Prop 13 value, that lower value is commonly referred to as a “decline in value” assessment, or simply the “Prop 8 value.” Prop 8 assessments, are TEMPORARY reductions for one year. Once a Prop 8 reduced value has been enrolled, that property’s value must be reviewed on the subsequent January 1.

As the real estate market begins to recover, the temporary Prop 8 value will be increased until it is restored back to its Prop 13 factored base year value. Increases to a Prop 8 assessment are not subject to the 2% increase limitation as are Prop 13 values. A Prop 8 value may be increased or decreased, depending on the market activity in your neighborhood. However at no point can the value be increased above your factored Prop 13 value.

Attention!A Message to Boat Owners

Dear Alameda County Residents:

Many vessel owners will see an increase in their 2022 property tax valuations!
 
The valuation factors calculated by the State Board of Equalization and provided to California County Assessors through LTA 2022/003 indicate an increase in 2022 values between 20-24% depending on the type of vessel. The State Board of Equalization reviews average retail sale prices for new and used powerboats, sailboats, and personal watercraft annually to develop the valuation factors. Per their research, these vessels have experienced large appreciation in value compared to 2021.

Sincerely,

The Alameda County Assessor’s Office
