Type IIIA matches up with your area figure. Others have noted the 55 ft criteria although in my version of the 2006 IBC it is contained in the "windowless story" heading but this is now corrected in the 2009 903.2.11. Also note certain areas may require sprinklers because of their hazard (2006 Table 508.2). Watch out for mixed occupancy conditions such as assembly that can trigger a building wide requirement at a lower area threshold. Your basement might require sprinklers. See 2006 903.2.10.
I don't know of a maximum area number, you have to back into it from other directions. Bill Brooks William N. Brooks, P.E.

I was looking for the section in IBC where they describe the maximum square footage where sprinklers are not required in a Group B occupancy. I could find reference to all of the other occupancy groups, but not B. Am I missing something? Todd G.
