Dead end corridor

[spabilove]

Hello,

I received the following comments from my reviewer and would like to gain a better understanding of the term 'dead end corridor':


'Please ensure that the corridor(s) do not exceed the maximum limits for dead ends (Ref. VCC 1020.4). See the corridor area by the bathroom.'


I measured the corridor where I believed the dead end was and respond as follows: 'A dead-end corridor is 18'-5" measured, and it complies with the maximum limit requirement.'


For further clarification, this is an assembly use without sprinklers, under VB construction type.


Could someone confirm if I have adequately addressed the reviewer's comment? Thank you

The reviewer may be confusing dead end corridor with common path of travel and measuring from the remote corner of the storage closet at the end of your corridor. If the measurement of your hand-drawn line is under 20 feet, you are correct.

The following is from the 2021 IBC Commentary:

And you also don't want to miss this:

1020.5 Dead Ends​

Where more than one exit or exit access doorway is required, the exit access shall be arranged such that dead-end corridors do not exceed 20 feet (6096 mm) in length.

If you only need one exit, there is no dead end....

And if that area needs only one exit, then as per YC in post #2 the governing factor is Common Path of Egress Travel (CPET) per table 1006.2.1.
