The DC Fire Marshal requires that all gatherings of 100 people or more to have a floorplan(s) / diagram(s) that has been approved by the Fire Marshal. The floorplan(s) / diagram(s) must match the set up on the day of the event.  In the event you are using an outside production company and they are providing floorplan(s) / diagram(s), it would best for them to submit the permit in case any changes need to be made.  We recommend to submit floorplan(s) / diagram(s) with the maximum number of attendees.  The permit can be submitted online at https://dcwebforms.dc.gov/fems/permit1/ and choose the appropriate option under “Public Assembly”.    If you are not using an outside production company or they are not supplying floorplan(s) / diagram(s), the hotel would be more than happy to submit a floorplan(s) / diagram(s) on your behalf.  There is a cost for each permit in the amount of $150.00 and a $50.00 Administration fee.
