Cal. Food and Agricultural Code § 11708

The director may refuse to grant any license and may revoke or suspend any license if the applicant or licensee: (a) Does not have, or has not maintained at its principal office and at each branch location, a person who holds a qualified applicator license issued pursuant to Chapter 8 (commencing with Section 12201) to actively supervise all operations performed for each such location as prescribed by regulations of the director. This subdivision does not apply to businesses that are licensed only in the maintenance gardener category. (b) Does not have, or has not maintained, adequate safe equipment and facilities to perform the operations undertaken or to be undertaken. (c) Does not have adequately trained personnel to perform the operations undertaken or to be undertaken. (d) Violates or permits the violation of any provision of this division and Division 7 (commencing with Section 12501) pertaining to pesticides or of any regulations adopted pursuant thereto by the director or any commissioner or any industrial safety order relating to pesticides issued by the Department of Industrial Relations. (e) Fails to maintain and report to the director or commissioner, as required, information concerning pest control performed or authorized to be performed by the license or the registration of the commissioner. Any hearing to deny, suspend, or revoke a license shall be heard under the Administrative Procedure Act, Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code. However, if the director finds on the basis of affidavits submitted to him or her by the enforcement personnel provided in Section 11501.5, or by injured parties, that the protection of the public welfare or safety requires immediate action, the director may, without hearing, temporarily suspend or condition the license of any pest control operator and shall forthwith schedule the matter for hearing. The director may terminate the suspension of, or any condition placed upon, a license upon correction of the defects of equipment, establishment of adequate safety practices, or any other corrective action as he or she deems satisfactory to assure compliance with the requirements of statutes and regulations. In that event, the matter may proceed to hearing as though the license had not been suspended or the conditions placed upon it.
