During plan review on a recent project, the inspection department required a switch be installed at each door capable of being used as an entry point to the building. Reference was made to sec. 1006 in the Building Code having to do with egress illumination. I can see that having a switch at every entrnce is good desing practice, but how is it that this portion of the Building Code requires a switch? Are there other portions of the Building Code that address this question?
