Cal. Government Code § 11524

(a) The agency may grant continuances. When an administrative law judge of the Office of Administrative Hearings has been assigned to the hearing, no continuance may be granted except by him or her or by the presiding judge of the appropriate regional office of the Office of Administrative Hearings, for good cause shown. (b) When seeking a continuance, a party shall apply for the continuance within 10 working days following the time the party discovered or reasonably should have discovered the event or occurrence which establishes the good cause for the continuance. A continuance may be granted for good cause after the 10 working days have lapsed if the party seeking the continuance is not responsible for and has made a good faith effort to prevent the condition or event establishing the good cause. (c) In the event that an application for a continuance by a party is denied by an administrative law judge of the Office of Administrative Hearings, and the party seeks judicial review thereof, the party shall, within 10 working days of the denial, make application for appropriate judicial relief in the superior court or be barred from judicial review thereof as a matter of jurisdiction. A party applying for judicial relief from the denial shall give notice to the agency and other parties. Notwithstanding Section 1010 of the Code of Civil Procedure, the notice may be either oral at the time of the denial of application for a continuance or written at the same time application is made in court for judicial relief. This subdivision does not apply to the Department of Alcoholic Beverage Control.
