California Code, Health and Safety Code - HSC § 1591

(a) When the director intends to seek the suspension or revocation of a license, the director shall notify the licensee of the proposed suspension or revocation and, at the same time, shall serve the person with an accusation. Upon receipt of a notice of defense from the licensee, the director shall set the matter for hearing within five days. The director shall make a final determination as to whether to suspend or revoke the license within 30 days after the original hearing has been completed.

(b) The director may temporarily suspend a license prior to a hearing when he or she determines that the suspension is necessary to protect the health and safety of the participants. In the event of a prehearing suspension, the director shall notify the licensee of the suspension and its effective date and, at the same time, shall serve the licensee with an accusation. Within 15 days of receiving a notice of defense from the licensee, the director shall set the matter for a hearing that shall be held as soon as possible, but not later than 30 days after receipt of the notice. The temporary suspension shall remain in effect until the hearing is completed and the director has made a final determination on the merits, which shall be made within 30 days after the hearing has been completed.
