The Director may, prior to approving an application for license under this chapter and from time to time during the license year, inspect any records of, and obtain information from, any applicant or licensee that the Director may consider necessary or advisable, to determine or verify any of the following:
In connection with the consideration of an application for a license under this chapter, and from time to time during the license year if the application is approved, the Director shall be authorized at any time during regular business hours to inspect the records of an applicant or any licensee and to obtain from the applicant or the licensee any information that the Director may deem necessary to determine whether an applicant qualifies for license, or whether an applicant or licensee has violated any provision of law or of this chapter relating to the qualifications to obtain or to retain a license.
Each applicant or licensee shall make available to the Director those records and furnish such information that the Director may request in connection with making the inspections authorized by this section, and shall, whenever requested so to do by the Director furnish or permit the Director to make one or more copies of the records as the Director may specify.
The failure or refusal of an applicant for a license or a licensee to make available to the Director the records or information authorized to be requested or to permit the Director to make a copy of the records or information, shall be cause for denial, suspension, or revocation of a license for the applicant or of the licensee.
