Thom, I just got off the phone wirth an AHJ moments before I read your comment doing exactly what you are suggesting. In my case it was a three story building (the lowest half below grade) connected to a two story building by a breezeway on a slope with ground level for the two story being at the same level as the roof of three story. Since they were connected and on the same property (essentially the samr building) he started out considering this a five story building with a more complex standpipe system than usually encountered. After a chat about fire department access, hydrant location, and tactics the standpipe completely disappeared. ALWAYS, as you say, discuss your plan with the end user.

As Steve has always reminded me, the "End User" or customer for a Standpipe is the Fire Department. This is one of the few times when the AHJ is also the user. ALWAYS! Ask them what they want, and why. It could be very educational, and save a lot of headache and lost revenue. We had a project today with Split Level access to the stairwell. Went to the AHJ discussed our concerns on standpipe location, Mid vs. Floor landings and which were both, as well as roof access. Guess what? They spotted the standpipe locations on our drawing and we're off to other money making projects. We 'll put them where they asked, and move on. (It makes life so simple when you can just give the AHJ some voice, and give them what they want up front.)
