The Detroit Office of Special Events and Film issues a no-fee general permit for all work being completed in the city of Detroit.  To obtain a DFO Permit, the film company must complete a Location Use Form (please call (313) 224-1606 for application) and submit it to the Film Office one month prior to filming. The DFO also requires all film companies to provide proof of adequate insurance for all film projects (Insurance Requirements ). In addition to DFO requirements, depending on the uniqueness of the project, additional city permits and/or fees may be required. Listed below are DFO answers to frequently asked questions.
