On Sunday, March 15, 2020 the Los Angeles County Board of Supervisors, following an announcement by California Governor Gavin Newsom, announced that all Los Angeles County facilities will be closed to the public beginning March 16, 2020 until further notice in response to the evolving coronavirus (COVID-19) emergency. This is a precautionary measure intended to help slow the spread of COVID-19 in Los Angeles County.

At this time the Assessment Appeals Board, based upon the directive of the Board of Supervisors, is currently postponing hearings through
May 1, 2020 or until Los Angeles County facilities are open pursuant to a Board of Supervisor's directive, whichever is later in time.

Assessment Appeals Applications can be submitted on-line at https://lacaab.lacounty.gov or downloaded and mailed to:
Los Angeles County Assessment Appeals Board
500 West Temple Street, Room B4
Los Angeles, CA 90012

Please check back as this notice is subject to change as the COVID-19 emergency evolves.

Our Mission Statement

Acting on behalf of the Board of Supervisors (Board of Equalization), in a judicial capacity, and acting on the basis of relevant evidence submitted at the hearing, make a fair, impartial decision within two years of filing, on all property assessment disputes between taxpayers and the Assessor.

An impartial decision is one that is based on the facts presented at the hearing, and not on personal knowledge of an individual Board Member; and one that does not for any reason give special favor to the Assessor or the taxpayer.
