Cal. Rev. & Tax. Code § 4804

The board of supervisors of any county may, by resolution, authorize the county administrative officer, or the county legal advisor, or the county auditor, or any other county officer, or a specified group of any county officers acting as a committee, to perform in its behalf any act required or authorized to be performed by the board of supervisors under this part, if such act is not imposed upon the board of supervisors by the Constitution.

The resolution may, at the request of the county legal advisor, provide for a waiver of the requirement for the written consent of the county legal advisor in any act performed under the provisions of this section.

The resolution shall enumerate those sections or subdivisions, or those portions of sections or subdivisions, to which the authorization is to apply, and shall specify administrative rules and procedures concerning any act performed under the authorization.

The resolution shall require that the county auditor record each act performed under the authorization.

The resolution may provide for review by the board of supervisors of any act performed under the authorization, or for periodic reports to the board of supervisors of any or all acts performed under the authorization, or both.
