In the BOMA definition of floor rentable area for a typical ground level floor, it states that the â€œfloor rentable area shall mean the result of subtracting from the gross measured area of a floor, the area of the major vertical penetrations on that same floor.â€ The definition of typical ground level does not indicate if thereâ€™s a basement.
I am looking at a two story office building that is slab on grade (no basement). Access to the second floor is provided by an elevator and two stairwells. Under your BOMA definition of floor rentable area, should I deduct the area of the elevator and stairwells on the first floor (ground level) and second floor? Or should the second floor areas just be deducted since it is the only floor that is vertically penetrated?
