I agree with the AHJ. Exception to closets on exterior balconies presumes they are within (or directly communicating with) dwelling unit. If you agree that the contested closets are outside of the dwelling unit, where is the exception in 13 that would not require sprinklers in these compartments? Methinks you're trying to split hairs with the "design criteria" intent argument - what do you mean by that, exactly? If hydraulics, then the answer is yes, but 13R also states that areas outside the dwelling unit shall be protected per 13, so I think that Chapter 8 of 13 applies, period.
The foregoing is my opinion only, and does not necessarily represent the opinion or intent of the Technical Committee on Residential Sprinkler Systems.

No fuel fired equipment. No heating or air conditioning equipment. Had it in my mind that these closets would not have to be sprinklered. Fire marshal is disagreeing. After review I am not so sure. Seems like the intent is to not require protection but by the letter I can't quite get there. Am I missing something? 2007 NFPA 13R 6.9.6 - "Sprinklers shall not be required in............(last sentence) ... "and other concealed spaces that are not intended for living purposes or storage and do not contain fuel fired equipment." - He pointed out that a closet is not a concealed space...... Ok then..... 2007 NFPA 13R 6.9.7 " Sprinklers shall not be required in closets on exterior balconies, regardless of size, as long as there are no doors or unprotected penetrations from the closet directly into the dwelling unit. - His point is that these closets are not on exterior balconies.... He says that it is outside the dwelling unit and therefore protected by NFPA 13. My comment is that I believe 2007 NFPA 13R only requires the "design criteria" of 13 to be followed for areas outside the dwelling unit. Clarified in section A.6.8.2. He says show me in 13R where you can exclude..... Thoughts?
