Asking a question on a building in NYS. It is 4 stories of B occupancy over 1 basement story of S-2 parking.
Table 504.3 allows for a type IIIB occupancy as long as the building is only 75' above the grade plane. The mechanical penthouses are pushing this limit. They are code-defined penthouses, only air handlers and nothing else in them. They are also less that 30% of the roof area.
I can't find anywhere in the code that states the penthouse area can be exempted from the building height. It would seem logical though based on all the other exceptions and limitations on the penthouse per code. Didn't see anything on commentary either.
Does the penthouse height count against the building height in table 504.3?
