Exiting from 4th floor single tenant elevator lobby - California - non high rise

[JPohling]

I must be having a brain fart or something..............We have done many a single floor tenant spaces within high rise buildings where we make accommodations to be able to exit back into the suite in an emergency situation from the locked elevator lobby in order to provide exit access to the stairs per CBC 1010.2.12.1 Access-controlled elevator lobby doors in high-rise office buildings.

I now have a non high rise building where they would like to have a full floor tenant. The stairs are not near the elevator lobby. I am not finding a code section that addresses this condition. We clearly need exit access from the elevator lobby if someone were to find themselves stuck in the elevator lobby. What am I missing? The building is fire sprinklered.

Are you looking for the requirement that establishes MoE from the elevator lobby?

or

Are you looking for a provision that parallels CBC 1010.2.12.1 and allows for controlled access from the elevator lobby to the exit?

2022 CBC 1010.2.12.1 Access-Controlled Elevator Lobby Doors in High-Rise Office Buildings​

For elevator lobbies in high-rise office buildings where the occupants of the floor are not required to travel through the elevator lobby to reach an exit, when approved by the fire chief, the doors separating the elevator lobby from the adjacent occupied tenant space that also serve as the entrance doors to the tenant space shall be permitted to be equipped with an approved entrance and egress access control system provided all of the following requirements are met:

1. The building is provided throughout with an automatic sprinkler system in accordance with Section 903.3.1.1.
2. A smoke detector is installed on the ceiling on the tenant side of the elevator lobby doors along the center line of the door opening, not less than 1 foot and not more than 5 feet from the door opening, and is connected to the fire alarm system.
3. A remote master switch capable of unlocking the elevator lobby doors shall be provided in the fire command center for use by the fire department.
4. Locks for the elevator lobby shall be U.L. and California State Fire Marshal listed fail-safe type locking mechanisms. The locking device shall automatically release on activation of any fire alarm device on the floor of alarm (waterflow, smoke detector, manual pull stations, etc.). All locking devices shall unlock, but not unlatch, upon activation.
5. A two-way voice communication system, utilizing dedicated lines, shall be provided from each locked elevator lobby to the 24-hour staffed location on site, annunciated as to location. Operating instructions shall be posted above each two way communication device.
   Exception: When approved by the fire chief, two-way voice communication system to an off-site facility may be permitted where means to remotely unlock the access controlled doors from the off-site facility are provided.
6. An approved momentary mushroom-shaped palm button connected to the doors and installed adjacent to each locked elevator lobby door shall be provided to release the door locks when operated by an individual in the elevator lobby. The locks shall be reset manually at the door. Mount palm button so that the center line is 48 inches above the finished floor.
   
   • Provide a sign stating:
   • "IN CASE OF EMERGENCY,
     PUSH PALM BUTTON,
     DOOR WILL UNLOCK
     AND SECURITY ALARM
     WILL SOUND."
   • The sign lettering shall be 3/4-inch high letters by 1/8-inch width stroke on a contrasting background.
7. Loss of power to that part of the access control system which locks the doors shall automatically unlock the doors.

Could you use delayed egress (1010.2.13)?

Classic, I was looking for something similar to the High Rise requirement for a non high rise building that would detail what is required to allow someone in the elevator lobby to access the exit stair that is located within the full floor tenant area that would be potentially locked. I am sure we could exceed the code by using the High Rise code section but I was thinking I am missing it somewhere.....................

potentially access controlled elevators after hours? but someone, somehow could find themselves in the secure elevator lobby without access to an exit.........

Perhaps! somewhat compromised suite security but may be the best solution.

Not by code they can't....
