California Code, Business and Professions Code - BPC § 2556.1

All licensed optometrists and registered dispensing opticians who are in a colocated setting shall report the business relationship to the California State Board of Optometry, as determined by the board.  The California State Board of Optometry shall have the authority to inspect any premises at which the business of a registered dispensing optician is colocated with the practice of an optometrist, for the purposes of determining compliance with Section 655.  The inspection may include the review of any written lease agreement between the registered dispensing optician and the optometrist or between the optometrist and the health plan.  Failure to comply with the inspection or any request for information by the board may subject the party to disciplinary action.  The board shall provide a copy of its inspection results, if applicable, to the Department of Managed Health Care.
