All exit access doors have to be 32" wide, not just the accessible ones (IBC 1010.1.1). The only significant difference is that maneuvering space isn't required at the ones that don't have to be accessible
1010.1.1 "size of doors" is subordinate to the scoping of 1010.1, which says "means of egress doors shall meet the requirements of this section".1010.1 Doors
Means of egress doors shall meet the requirements of this section.
So we have to assume all these doors (openings, really) are considered Means of egress doors?
1010.1.1 "size of doors" is subordinate to the scoping of 1010.1, which says "means of egress doors shall meet the requirements of this section".
If only one exit is required by code, then only one door needs to be a means of egress door complying with 1010.1.1.
The question is, what are all the other doors for? If you are (voluntarily) providing them as additional means of egress doors, then yes every door that is provided as a means of egress door must be means of egress door with min. 32" clear. Hypothetically, there could be no difference in size or configuration or appearance between a non-egress door and a giant casement window.
Your problem is that all those other doors may look like means of egress doors, setting you up for liability in case someone has a problem in an egress emergency. Suggestion: place a "Not an Exit" sign on the wall next to every non-egress door, and that should help mitigate liability.
Same discussion we have had before and we do not all agree, but I lean hard on the "provided for egress purposes"....The OP did not say what was on the other side of those doors, but since the word”exit” was used, let’s assume for sake of discussion all that these “extra” doors open directly to the exterior.
In that case, I don’t think that stairs are an ideal code analogy, because stairs have a single purpose: a vertical path of travel. Doors are openings that can have multiple purposes:
1. Path of travel.
2. An opening to let light into the room
3. An opening to naturally ventilate a room.
4. An Emergency Escape and Rescue Opening (which can be smaller than 32” wide).
If the sole purpose of the other doors were #2 or #3, they might not need to be considered as exit doors. Maybe they are more analogous to really tall casement windows with a window sill that goes all the way to the floor. I’ve seen this with operable sidelites adjacent to a door; I’ve seen this in restaurants in lieu of an operable wall. Just because it looks like a door doesn’t mean it MUST function as a means of egress.
UPDATE: I overlooked post #3 where the OP clarified that this is a room-within-a-room, so my point #4 above is not applicable to this situation. Piants #1-3 may still be applicable, depending on design intent.
What is applicable is this, in red:
1010.1 GeneralDoors in the means of egress shall comply with the requirements of Sections 1010.1.1 through 1010.3.4. Exterior exit doors shall also comply with the requirements of Section 1022.2. Gates in the means of egress shall comply with the requirements of Sections 1010.4 and 1010.4.1. Turnstiles in the means of egress shall comply with the requirements of Sections 1010.5 through 1010.5.4.Doors, gates and turnstiles provided for egress purposes in numbers greater than required by this code shall comply with the requirements of this section.
So, if the doors are provided FOR EGRESS PURPOSES, then yes they need to be 32" clear. This qualifier in red sentence implies that doors can be also provided for reasons other than means of egress.
Doors, gates and turnstiles provided for egress purposes in numbers greater than required by this code
Yes....yes it does.....But the code does not say "provided for egress purposes," the code says "Doors in the means of egress ..." A room may only require on door, but have three doors that all open to corridors connecting to exits. Which door is "provided for egress purposes" and which doors are surplus"
Whichever one the designer details that meets the code requirements..Which door is "provided for egress purposes" and which doors are surplus"
Whichever one the designer details that meets the code requirements..
Or just put exit signs over the 2 that are exit components....IMHO, that eliminates the other two doors unless they are clearly and permanently marked "NOT AN EXIT." Most architects and most owners will not want such signs on their expensive wood doors in an office setting. And it makes no sense to mark a door "NOT AN EXIT" when it leads directly to an exit or to an exit access corridor. Such signage is usually reserved for doors such as closets, mechanical rooms, or doors leading to dead-end corridors.
It says it in the wording I highlighted in red in post #9. Please respond to that entire statement in red.But the code does not say "provided for egress purposes,"
