A lot of office buildings and public transit depot buildings are being designed with "quiet" or "wellness" rooms for tired employees to take a break and "rest," leading a lot of AHJs to ask if these rooms are R occupancies.
The designed use is not a sleeping room and many clients "prohibit" sleeping but everyone agrees that it could be used as a sleeping room.
Typically they're size for 1-5 people and have lounge chairs (no beds) so they fall under the accessory use category to the rest of the building. For example, assume a multi-story office building where each floor has one of these rooms, less than 500 square feet, no beds just chairs, room is entirely open inside.
How would you treat these rooms and how would you address the requirements for corridors in the building assuming its a sprinklered building?
Thanks in advance.

To date, I have been considering these as standard support spaces for the occupancies for which they are located within.

Mayby I'm missing something.

I think the suppression standpoint is pretty easy to follow, I think the question is more life safety code based. If you have a standard B building and you put sleeping occupants inside of it, what occupancy would you call it and how would it affect the rest of the building? Or would you even need to call it an R occupancy?

See "Regulations, Codes & Standards Q&A: Physician on-call sleep rooms" for a similar interpretation (https://www.healthcarefacilitiestoday.com/posts/Regulations-Codes-Standards-QA-Physician-on-call-sleep-rooms--20603)

Based on that analysis I think its safe to say that a 1/2 hour rated corridor would also be required for the means of egress for the R occupants, would you agree?

It depends ...

These rooms are becoming more common. If located within an office, I would design the room as Light Hazard and ensure corridors (dead-end) are designed per Group B.

As others have said I'd include these as part of the B areas. For FP particularly I'd look at LH not residential protection for the sprinkler system. Might want to bump up the FA to include a horn strob in the room if someone 'forgot' to read the sign about not napping in the room.

I'm not sure about a transit building, but in an office, I would expect the employees to be more-or-less on the clock and only in the building during daytime hours (someone working overtime at night could fall asleep at their desk anywhere in the building), and would not be permitted to take an extended "dead to the world" nap.

These are rooms specifically designed to let employees step away from their work for an extended period of time, mostly geared towards employees who wouldn't be behind a desk all day. Its not intended as a traditional break room, more like a nursing station room; you're not working but you're also not going to spend your entire day in there.

As indicated above, in an office building, I will protect it as the remaining areas as a LH occupancy (minimum).
5/15/2023 10:33:05 am
Agree with everyone else, it's the occupancy of the surrounding (presumably office) area.

Rereading the question again and the replies.... I think this guy is asking more in regards to fire alarm than fire sprinkler.
5/19/2023 08:57:53 am
Your last sentence hit the nail on the head; the intent isn't sleeping but its almost certainly going to occur. Even though its not permitted its one of those things that is going to be difficult to police, like people using wedges on fire doors that don't have hold-opens installed. It a problem than can be engineered around (put the doors on hold opens and they won't get chocked open) but real question is how much additional protection should reasonably applied to protection a potential sleeping occupant? Is the rated corridor that an R occupancy requires really necessary? Is CO detection necessary if there are no CO emitting appliances or equipment?
