Occupancy division of space

[eyden]

New to the forum and have read through old threads to answer some of my questions in the past. Couldn't find anything on this though.

I'm designing a bistro/bar and butcher shop in an existing building. The current space is is divided down the middle by a wall, with a 6'5" opening between the two spaces. The plan is to put the bistro/bar on one side of the wall and the butcher on the other so that the butcher can be closed at 6pm, and the bistro can stay open.

-For an occupancy calculation, can I count the butcher and the bistro as separate spaces as is, or would I need to put a door between them in the opening? I'm hoping to get each occupancy under 49 so I don't have to add an exit.

-If this doesn't work, the diagonal length of the space is about 81'. Can I move the existing doors so that they are more than 27' apart, even though they are both on the front wall? (the building will be sprinklered)

I'm in California, by the way.

I can't attach the image, so here's a link.

Two businesses owned by same person???

If so, I am saying exiting would be the total for both businesses, no matter who is open or closed.

if the exits are on the front wall, can people use them when the other business closes?? If so seems legal, you have two exits, properly spaced

Unless it is for business operations, put the two exits on front wall, and opening between them up front??

Not sure what you could use in the opening?? Door, double swing door?? If you wanted something

What is the sq ft of each space

 

[cda]

1004.9 Multiple occupancies. Where a building contains two or more occupancies, the means of egress requirements shall apply to each portion of the building based on the occupancy of that space. Where two or more occupancies utilize portions of the same means of egress system, those egress components shall meet the more stringent requirements of all occupancies that are served.

Yes, two businesses, one person.

When the other business closes, the opening to the butcher would be blocked off, resulting in an occupiable space of fewer than 49. Can the use and occupancy be changed like that?

Thank you for all the quick responses!

As I'm understanding it now:

-The butcher is an M occupancy with an occupancy of 36 (1080sf/30)

-The bistro is a B occupancy with an occupancy of 44 (654sf/15) or 47 (adding 3 for the kitchen)

-Based on Table 508.4, no separation is required between M and B.

-Then based on 508.3.1, 508.3.3, and 1004.9, I can apply the code to each space on its own, even though they are not physically separated.

-Because they are both under 49 occupants, I only need one exit for each.

I would say generally should work.

Indirectly meets code.

As long as no one is in the butcher area, unless the exit door in that space is unlocked.

Seems like you would need a barrier, to keep people from wondering.

Than there are the days when owner wants a big party, so people are on both sides.

Just put panic hardware on the doors, and no problem.

Just have to get the ahj to bless it

Awesome. Thank you so much for the help. There will definitely be a barrier put up at night.

Fortunately, the city actually really wants this project, so I think they'll be willing to work with us on it.
