Elevator

See attached quick photo-FACTS-

- 3-story building.
- Mixed Occupancy, second and third floor R-2 Occupancy.
- 2 Exits and Elevator Shaft (prev owner never installed)

PROPOSED-
- 3-Story Building
- Mixed Occupancy, second and third floor R-2 Occupancy.
- 5 Dwelling Units per floor (2nd and 3rd)
- Eliminate 1 exit, install Elevator and keep existing staircase
- Automatic Sprinkler System will be installed.

I understand typically a single exit is permitted for a maximum of 4 units as indicated in table IBC 1006.3.3(1)

• R-2 Occupancy
• 4 Dwelling Units Maximum
• equipped with automatic sprinkler.
• 125 feet Max Travel

My question is regarding an Elevator being used as an accessible means of egress in place of the second staircase. I understand this would require Standby Power and I have an exception with Area of Refuge due to Automatic Sprinklers.

I know there are 3 elements of a means of egress, so in my case-

• Exit Access - Hallways - Distance Travel will be 100 ft or less
• Exit- Standby Power Elevator and Staircase
• Exit Discharge - Elevator and Staircase exiting to public way.

One other point is the elevator and the staircase are in the same area. Issues there?

Thank you

The elevator and stair are way too close together to be 2 exits...

I should add that I could rebuild the other staircase to meet code and eliminate the staircase hugging the elevator.

How is the stair you want to remove in any way an exit?

Worse, they are both off the same lobby, and there's only one door from the space into that lobby. No matter what you do to the elevator, that stair and elevator will only be one means of egress.
