California Code, Health and Safety Code - HSC § 114405

(a) A permit may be suspended or revoked by a local enforcement officer for a violation of this part. Any food facility or cottage food operation for which the permit has been suspended shall close and remain closed until the permit has been reinstated. Any food facility or cottage food operation for which the permit has been revoked shall close and remain closed until a new permit has been issued.

(b) Whenever a local enforcement officer finds that a food facility or cottage food operation is not in compliance with the requirements of this part, a written notice to comply shall be issued to the permitholder. If the permitholder fails to comply, the local enforcement officer shall issue to the permitholder a notice setting forth the acts or omissions with which the permitholder is charged, and informing him or her of a right to a hearing, if requested, to show cause why the permit should not be suspended or revoked. A written request for a hearing shall be made by the permitholder within 15 calendar days after receipt of the notice. A failure to request a hearing within 15 calendar days after receipt of the notice shall be deemed a waiver of the right to a hearing. When circumstances warrant, the hearing officer may order a hearing at any reasonable time within this 15-day period to expedite the permit suspension or revocation process.

(c) The hearing shall be held within 15 calendar days of the receipt of a request for a hearing. Upon written request of the permitholder, the hearing officer may postpone any hearing date, if circumstances warrant the action.
