I know that if it is combustible and the FP System is per NFPA #13 the hair we are splitting is if it is LH or OH but, wouldn't whether it is considered a story or not be something decided by the architect and the local building department? If the plans call it an attic or don't call it anything at all and it's not calculated as part of the total square feet of the building then it should be an attic. By calling the attic a an occupied space a three story building with an accessible attic would be 4 stories and require a standpipe system.

Additionally, 302.1 of IBC 2009 say's "A room or space intended to be occupied at different times ---- " With a door, how can it be a concealed space. Even a locked door does not create a concealed space, just one with limited access. The fact that the roof goes to 0'-0" at the eaves, only means that there is not true wall, similar to the ever popular A-frame. I say you've got a "Room", determine the occupancy and provide appropriate protection as required by the applicable standard. My farthing's worth. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Greg McGahan Sent: Wednesday, January 19, 2011 8:19 PM To: [email protected] Subject: DEFINITION OF A CONCEALED SPACE Is a large are with a concrete floor, exposed roof trusses with a door for access so the area can be utilized as a room (for storage presumably), considered a room or a combustible concealed space?
