CA Gov't Code Section 29550.3

(a)

A city which books or processes persons to a jail administered by it and which does not otherwise incur an administrative fee from the county, may establish and collect an administrative fee for an arrested person pursuant to the same standards and procedures set forth in Section 29550.1.

(b)

Any city whose officer or agent arrests a person is entitled to recover from the arrested person a criminal justice administration fee for administrative costs it incurs in conjunction with the arrest if the person is convicted of any criminal offense related to the arrest, whether or not it is the offense for which the person was originally booked.

(c)

Any booking fee imposed pursuant to this section shall be charged to the person booked and not to the arresting entity.

(d)

Nothing in this section shall be construed to limit the ability of any city to enter into agreements with other local arresting agencies authorizing the imposition of a criminal justice administration fee by that city upon those local arresting agencies for reimbursement of expenses incurred with respect to the booking or other processing of persons into a jail facility operated by that city.
