2018 IBC 1027.5 Location

[EyeBeeSee]

Does 2018 IBC 1027.5 Location mandate a minimum 10' between the walls of the exterior stair way in plan? I understand the 10' area vertically along the wall the stair but this is written to sound like you can't have 8' between doors.
3story R-2 occupancy type VB fully sprinkled.

I just had a project with a similar situation, assuming the pathway in your situation is an open-ended corridor (i.e., enclosed at the ceiling) and is not open to the sky. I treated both walls as 1-hour fire barriers as required for interior exit stairways per Section 1023.2 but with 3/4-hour unit entrance doors per Table 716.1(2) as "Other fire barriers." The B.O. might require 1-hour openings and treat that as a variation of an interior exit enclosure with each unit entrance door considered an exit.

Is what you have an exterior exit stairway, or is it an egress balcony (IBC section 1021)?
