AS being one that as screamed from his soap box about inappropriate use of 13R with mixed occupancies, this is exactly the type that should allow a 13R system. The building code can not address the nuance of "other occupancies" depending on the sole use of the residential occupants so 13R provided guidance. Are the classrooms expected to remain in use if the roof burns off - NO. They are there just for the residents to use. The exception to this philosophy is when you have a concentrated use (ie bigger assembly uses).

Let's put this in perspective:
One 535 SF classroom
One 312 SF Conf room
One 160 SF Office
Two 106 SF offices
One 118 SF Laundry
That's substantially less than run of the mill hotel back of house.

Are the business offices of a hotel, not to mention their conference rooms, incidental to the running of a hotel? Commercial laundries, not a 7' x 17'
cubby.

To me this sounds like a 13 system. Incidental is defined as "of a
minor, casual or subordinate nature". I'm not sure that offices and
classrooms fall under that category for an otherwise residential
occupancy since that could stand on their own. My thought is that an
incidental occupancy (such as an office or  laundry room for a hotel)
is one that could not reasonably exist without the primary
(residential). I vote for mixed use, hence 13.

We have a project in which the majority of the building is dorm rooms; 2nd flr (top) is all dorms, with a few more dorm rooms and a few classrooms
and offices on the first floor. Small basement is mechanical only.
Entire building footprint is a whopping

The classrooms are for the use of the students that reside in the dorm;
Offices for faculty that teach there.

Overall concept is suburban campus college has this building in the city
for
students to study government and urban life. So the non- residential areas
are incidental to the residential nature of the building.

The Architect has deemed the building A3 for the first floor, R2 on 2nd floor. Naturally the one hour separation is at the first floor ceiling.

If this sounds a little strange, at least it's not #13TR, elderly housing over tire storage:) This IS located in a locale where 13d tank/ pumps feed
3
story office buildings, with poly tanks located in restaurant storage area,
and CPVC in OH2. Sure, that will make the judge understand ?

Anyway, would % of use and other uses being for the occupants make this
look
#13R to any of you?
