Homeowners’ Exemption

Homeowners who own and occupy a dwelling on January 1st as their principal place of residence are eligible to receive a reduction of up to $7000 off the dwelling’s full cash value.

The law provides that once you file a homeowners’ exemption and receive the exemption it is not necessary to file each year as long as you continue to occupy the residence on which the exemption is claimed.

“Dwelling” means a building, structure or other shelter (including boats) constituting a place of abode, whether real or personal property.

If you feel you qualify and are unsure whether you already have the homeowners’ exemption you may inquire by going to the Property Assessment Information section of our web site.

If the exemption was previously granted and you no longer qualify for the exemption, the law requires that you notify the Assessor’s Office as soon as possible. To download and print a Request to Remove Homeowners’ Exemption Form, click here  (PDF) or go to Forms.

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.
