Escape rooms are a great exercise in supervisory control, fire safety planning, evacuation, etc. We worked with our local escape room (along with the Building Department (change of use)) to ensure there was adequate warning and evacuation. We viewed the property as an assembly occupancy and ensured all requirements were met (the OBC was helpful in our circumstance). We are treating it on a case by case basis should a new one open up.  We treat them as we would any other assembly occupancy under the OFC.
