Maneuvering clearance

[Sifu]

In this case, it is likely (since they haven't specified yet) that the stair in question is an AMOE. It is also uncertain (since they haven't specified it yet) whether it is exit only. It may be a restricted entrance. Finally, if it is an AMOE, the 12" push maneuvering clearance has not been satisfied either. The result is they have some explaining to do, and likely a little bit of a redesign.

If it's FHA see below from FHADM.

Good catch on the re-entry in the code commentary. (New code section is 1010.2.7). I'll thankfully concede that, though it remains ambiguous in the code how a stair that is not meet the definition of "Accessible route" is required to have a landing with an accessible route. This should be clarified in future code updates.

Stairway reentry may or may not be a concern (but for this project probably is)

Devils advocate here:
Accessible route & AMOE are separate things.
Door approach is listed under chapter 4, which ties to your accessible route. not the AMOE.
Pullside from inside the stair would not be required since it is not on the accessible route.
Stairway re-entry is for different reasons and would not require to have 18" pull side.
The same way you wouldn't have this scenario on a fire escape as a regular means of egress
The same way for apartments not along the accessible route you don't need pull clearance

Please note that you must allow people to re-enter floors from the stairs. Why would you ever have a sign that says "No Re-entry" in a stair shaft?

Correct me if I'm wrong but if you choose to re-enter the floor and leave your AMOE stair, then you are no longer egressing, you are now accessing or "entering" the floor. You cannot provide an accessible route using a stair (includes a landing). Ever seen an exit sign on the inside of stairway?



Please tell us where in the code stairways are required to be an accessible portion of the building, besides use as AMOE?

I've already provided the code and FHA sections in earlier posts in this thread. Please read those. (there are two pages, maybe you missed the first?)

I don't know how many times it needs to be repeated that AMOE and accessible route are not the same thing.

There are many buildings where the stairways are the only MOE. In CA we have an exception to the door maneuvering space for the entry doors to a stairway. This does not remove the maneuvering space requirement from the doors exiting the stairway. 11B-207.1 exception 4
