The Board of Fire Commissioners, with the concurrence of the City Administrative Officer, shall determine on a regular basis the verifiable costs to the City for the inspection and enforcement activities, and the administration of the Unified Program elements, associated with the businesses plus the applicable State service charges. The Board shall use said costs to develop or to amend a Schedule of Fees, hereinafter referred to as “Schedule,” so as to recover City costs in connection with the administration of this section and any other section of this Code for inspection and enforcement activities, and the administration of the Unified Program or any of the elements, associated with the businesses, and to collect any State mandated fees. Said Schedule shall be no higher than necessary to recover such costs. The Board may amend the Schedule based upon changes in City costs at any time during the fiscal year.
