Building Code (1022.4 in 2012) prohibits openings into exit enclosures from all but normally occupied spaces. So how does one exit from normally unoccupied spaces?
Consider an entire upper floor of normally unoccupied spaces (mechanical, toilets, etc.) in construction that requires rated exit enclosures; there appears to be no way to exit the floor.
Consider an unoccupied roof; there appears to be no way to exit the roof using an interior stair, even though code requires extending a stair to the roof if you're over 3 stories.
We have been allowed to access the stairs via a corridor or vestibule in the past, but that is not how the code is written, and certain officials won't use logic.
