Open air corridors in R-2 occupancy, building type III-A

[Shams Gannon]

I'm looking for any part of the IBC that limits the construction of open air corridors in a Type III-A building used for an R-2 use. Our client wants to do a 5 over 2 mixed use building with fire rated stairway enclosures, but open air corridors as part of the means of egress. I assume there's something in chapter 10 that addresses this, but I'm having trouble locating anything that directly limits the height of an open air corridor or if a means of egress can be open air.

Any help is appreciated!

If it is not in the book you can do it.

Not sure the question, have seen it before

There is no prohibition for open corridors in the IBC. If the corridor is 50% open down the long side, then it is no longer a corridor but rather an egress balcony, which has its own requirements in the IBC.

Thanks RLGA and CDA, both helpful answers!
