Notwithstanding Section 14090, the commissioner may establish license periods and renewal dates for all licenses issued pursuant to this chapter so as to distribute the renewal work to permit the most efficient and economical use of personnel and equipment. In such cases, to the extent practicable, provision shall be made for the proration or other adjustment of fees so that no person shall be required to pay more than that which he or she would have been required to pay had no change in license periods or renewal dates been made.
