Where work for which a permit is required by the Codes herein adopted is started or proceeded without first obtaining the required permit, a permit shall not be issued until all past due enforcement costs are paid. The enforcement costs are the actual costs, as specified in the City's Fee Schedule, or other applicable City enactment, and must be paid on demand. The Building Official may use any legal means available to collect enforcement fees. The payment of such enforcement fees shall not relieve any person from fully complying with the requirements of these Codes in the execution of the work nor from any other penalties prescribed herein. Any section in any of the Codes herein adopted which is in conflict with this Section is hereby repealed.
