Dead-end corridor interpretation in a story, unsprinklered I-4

[Ryan Schultz]

I have a 1story, unsprinklered I-4 Daycare (probably an E, based on 308.6.1 Classification as Group E).

Clients want to add another room as illustrated below.

Question: I assume the corridor, highlighted in yellow, is not a dead-end corridor because all the rooms have 2 means of egress. Is that a correct interpretation?

Thanks, Ryan

Yes, it is a dead end corridor.

Interesting question

I am thinking no

1. since each room has two ways out.

2. With the addition of the new room,,,

a. if that door swing into the room meets code????

b. Put and exit sign, on the corridor side, directing into the new room.

c. intervening room rule, and if it was a dead end, not any more???????????????

Maybe for the individual rooms that have doors into the corridor; however, the Sitting Area appears to need two means of egress. Thus, the corridor leading from that space would be considered a dead end if it does not lead to an exit. If it is a Group E with a sprinkler system, this could be as long as 50 feet.

I agree with Ron. If it is longer than 50 feet, you could add in some cross corridor doors to reduce the length of the corridor...

Doors 100'a/b and door 106a/b????????????

Asked same question to our AHJ. Their response...

"2015 IBC 1020.4 addresses the limitations of dead ends as related to corridors. If the two rooms you reference have access to the same corridor, but have the access doors located between the room and the corridor capable of being locked, the limitations for a dead end corridor needs to be examined, if appropriate. If either one of the two doors will not be capable of being locked, AND there is an exit sign above the non lockable door, AND the egress through an intervening space meets the requirements of IBC 1016, one may be able to address the openable door as an exit. Without plans, a specific answer cannot be provided at this time."

In this scenario, I have a feeling section1016 would not be satisfied.

maybe yes. Maybe no

 

[Ryan Schultz]

whether a space is accessory to another, has always seemed to blurry to me and open to interpretation.

Common tenant, or individual subleases?

 

[Ryan Schultz]

One daycare tenant throughout.

So, you are seeking to create a room within rooms?
