I would like to install a door in an existing building for deliveries. It is not to be an egress door for the public; the egress route and doors are already accounted for in the building. The code interpretation has been this door must have a level landing on each side. My contention is that this is a requirement for only egress doors - since it is in the egress chapter, and not every door would require a level landing on each side. Any comments?
