I received a question from an architect last week, and this is not the first time it has come up.  I’m wondering if any of you have run into this situation, or if you have any thoughts on the intent of the model codes.

Stairwells typically have one door per floor, and for reentry purposes these doors (if locked) are required by the I-Codes to be able to be unlocked remotely.  If you’re not familiar with the stairwell reentry requirements, there is more information in this recent Decoded article.

In some buildings, a stairwell may have more than one door serving a floor.  In that case, are all of the stair doors required to unlock remotely during a fire, or could one door be designated as the reentry door?  Refer to the plan below for an example of this application.
