The building code and NFPA 14 both state that where required, standpipe hose connections shall be installed on every floor level landing of every required exit stair. There are obviously additional considerations, such as whether the local FD prefers connections on intermediate landings instead of floor level, or if a stair goes to the roof or not. In this case, you’ve ID’d a condition where there’s no access to the first floor from the stairs (if I’m understanding correctly), so there’s not any value to the FD if valves are located there.
Some FD’s will waive hose connections on the level of apparatus access as they can pull attack lines directly into the building from their pumper. Some FD’s may want a valve or valves in another location on that ground floor. Bottom line is (broken record here) that you should consult with the responding FD to place the valve or valves in a location that they approve and for which they can pre-plan and ultimately, use the valve as safely and effectively as possible. The foregoing is my opinion only and does not represent NFPA or the NFPA 14 Technical Committee, nor intended to serve as an interpretation of the standard.

I am working on a small 4 story building where we are required to install a standpipe (as well as a full 13 sprinkler system). The first floor consists of a conference area, office space and various mechanical and storage rooms. The conference space and office area have direct access to the outside, but there is no communicating space between them. The 2 stairways lead to an outside access only. The elevator lobby has an outside door but does not connect to the stairways or conference and office spaces. The total footprint of the building is less than 3000 sqft. Where do you put the hose valve on the 1st floor?
