Here in Winnipeg (if not Canada), each location must get 1 license per screen, which is a Screen/Movie Theatre License.
One costs about $160.00, plus you need occupancy loads, in which every room has a liscense as to how many it can officially hold, in otherwords, all theatres must display how many each auditorium can hold, how much the lobby can hold, booth, concession, etc... These room occupancy licenses are free, but you must be approved.
