Roland, I don't know that I am. Look at the requirements of of 903.2.8 for Group R. It mentions that I need to comply with Section 903.3. Under section 903.3 - 13D is also an option. That doesn't mean that 13D is appropriate. It might be, but it would depend on the building height/area and whether it is a hotel, dorm, etc.
I contend that one must go back through the steps of identifying the occupancy and work through the tradeoffs, heights, bldg area, etc. to get to the appropriate section of Chapter 9. In this case the occupant load is part of the driving factor of which way one should turn. And if that leads me into the IRC... then great. But if not of to 13 / 13R land I go. Best Regards, Ken Holsopple Why are you unnecessarily limiting yourself? In other words, I disagree. You are right that 308.2 kicks you to R-3 with fewer than 5 persons but where does 903.2.6 say ANYTHING about using 903.3.1.3 in R-3. It says I-1 can use either 13R or 13D. Granted this undoubtedly stemmed from many houses being converted to a small I-1 but it doesn't say anything about SIZE or construction type. Now I assume that an AHJ could argue that the description of 903.3.1.3 would limit you to something similar to a one-and two family dwellings (which I've heard of houses with 13D systems just over 200,000 sf) but it certainly isn't very strong. I just now got it cleaned up that you actually have to inspect 13D systems in an I-1. Now we'll wait for our AHJ code boys to elaborate.
