Revenue and Taxation Code § 3384

The board of supervisors may provide by order for mailing to each assessee on the published delinquent list a copy of the items delinquent assessed to him and, if so ordered, the copy shall be mailed to the assessee at his address as shown on the roll. This section gives no one any right to receive the copy of items delinquent, and neither the county nor any office or employee is liable for failure of the assessee to receive the copy or for any mistake in connection with the mailing.
