Des Plaines FAQ
Can I add a deadbolt to my office suite door?
Only if it is interconnected with the latch so a single motion releases both, and the door is not part of a required egress path with more than 50 occupants. Otherwise it violates IFC 1010.
Are classroom barricade devices allowed?
Illinois permits limited classroom security devices but they must allow free egress, not require special tools, and meet state Office of the State Fire Marshal guidance for active-shooter response.
