Every time we have run into this situation it has been with metal framing. The AHJ has looked at it and determined that the space around the unit is considered a non combustible concealed space and thought it equivalent to an air handler unit. In every case we have looked at the clear space between the unit and framing has been a few inches an no sprinklers were required.
From: Sprinklerforum <[email protected]> On Behalf Of Prahl, Craig/GVL Sent: Tuesday, August 21, 2018 9:49 AM To: [email protected] Subject: RE: [EXTERNAL] Re: NFPA 13 Closet Definition Call it a closet or a mechanical space but if your mandate is to provide sprinklers throughout, then that space isn't exempt from being sprinklered. Maybe consider a sidewall from an adjacent accessible space or extend the height of the access panel? If NFPA 13 doesn't' list apartment closets with the hotel/motel exception, it doesn't apply. The hotel/motel closet area is also limited to 24 sq. ft. Most apartment closets are larger than that. D.1.1.6.1 only exempts sprinklers in closets under 12 sq. ft. but still requires sprinklers for closets containing equipment regardless of size. But you need to read the Introduction to Appendix D as this Appendix is for information and is not part of the NFPA 13 Standard requirements. So, unless NFPA 101 is an adopted standard in the Jurisdiction where your project is located or has been otherwise required, Appendix D is not applicable. The Architect of Record should have established the applicable codes to be applied to the project. Check there to determine what is and isn't applicable.

Is it still considered a closet if it does not have a door? There is just a removable panel to access the HVAC unit. There would be no access to the sprinkler at the top of the space. NFPA 13 also requires sprinklers in all closets except hotels & motels. Does Annex D 1.1.6.1 overide this requirement for clothes closets in apartment buildings?
