Dead End Corridors

by EVstudio AEP on June 10, 2016

One of the more novice mistakes that are made in the design of commercial buildings is the dreaded dead end corridor. This is a corridor which doesn’t lead to an exit but to a dead end where someone would have to turn around and back-track in order to find a way out. Normally this just encourages a little extra exercise but in the event of a fire or other emergency, can be deadly. This isn’t to suggest that you would build a corridor to nowhere but rather it may be a long corridor to access a single space without an additional exit.

A dead end corridor can’t be more than 20 feet in length. If a building is completely sprinklered then the limit increases to 50 feet in a number of cases. Check 2012 IBC section 1018.4 for specific exceptions. You’ll see that a room itself cannot be a dead end corridor if it is wide enough to be a room rather than a hallway.

However, make note that this requirement is only enforced when more than one exit or exit access doorway is required.
