Aurora, CO Building Safety: Door Locking Hardware (2026)

Aurora amends IRC Section R311.2 to require a deadbolt on every exterior door of an individual dwelling unit or guestroom in a group R occupancy (except hotels and motels), including the door between an attached garage and the home. The deadbolt must be a springless lockbolt operable by key from outside and a knob or thumb-turn inside. Exterior sliding glass doors instead need a locking bar, pin, or bolt device. No deadbolt or other security device may be mounted higher than 48 inches above the finished floor. The rule applies to structures with building permits issued on or after September 1, 1983, and does not bar adding extra devices like night latches or security chains.
