Some elevator lobbies have immediate access to an exit stairwell, some do not.
In many buildings, tenants want/need security between the elevator lobby and tenant space, but the codes require a means of egress from the elevator lobby to a stairwell.
When there isn’t direct access from an elevator lobby to an exit stair, the two sets of model codes currently include different mandates for the doors leading out of the elevator lobby into the tenant space.
Elevator lobby doors serve as crucial points for egress and security in buildings. Different model codes such as NFPA 101, IBC 2021, and new 2024 IBC sections outline specific requirements for these doors. They must be equipped with fail-safe hardware, such as electromagnetic locks, to automatically unlock in emergency situations. Compliance with fire safety measures, automatic unlocking mechanisms, and two-way communication systems are essential to ensure occupant safety and code adherence.
