I am working on a remodel to an existing building under the 2015 IEBC. Change of use, unsprinklered. It is necessary to revise the layout such that we are creating 2 new dead end corridors that are between 20 feet and 35 feet long. In the existing layout one of these corridors was 20 feet long to a dead end, the other continued to an exit (the exit is not required, other existing exits satisfy requirements).
By my reading of IEBC Section 805.6, 35 foot dead end corridors are allowed. There is no distinction as to whether or not this applies to new or existing corridors (there is a distinction between new, existing, and extended corridors in the subsequent exceptions). There is some debate in the office with others suggesting that the 35 foot rule only applies to existing corridors and new would have to comply with the 20 foot length called out in the IBC.
Is it an accurate interpretation to proceed with a new 35 foot dead end corridor?
