I think this might have been posted before but I can't find it.
2009 IBC 1014.2 prohibits egress through a storage room. If there is an office in the middle of a warehouse how should one make an exit access? Would you need to build a horizontal exit?
 
Storage room and storage use are 2 different things, but...

1014.2 Egress through intervening spaces. Egress through
intervening spaces shall comply with this section.
1. Egress from a room or space shall not pass through
adjoining or intervening rooms or areas, except where
such adjoining rooms or areas and the area served are
accessory to one or the other
, are not a Group H occupancy
and provide a discernible path of egress travel to
an exit.
 
Also, 1014.2.1 Exception: Means of egress are not prohibited through adjoining or intervening rooms or spaces in a Group H, S or F occupancy when the adjoining or intervening rooms or spaces are the same or a lesser hazard occupancy group.

Table 508.4 groups B with S-1. S-2 is a lesser hazard than B.
 
It says storage room on the plans. Seams to meet the definition of a room.

I don't understand how you can use table 508.4 to determine which group is a lesser or higher hazard. It says a 2 hour wall is needed between B and S2 when not sprinklered. How do you know which is a higher hazard?
 
As asked earlier

Who is going to use the office

The supervisor for that area

Or

The out side sales division, who have no connection to the people in the warehouse

That is the question


A floor plan might help
 
Define is it a (1) storage room, (2) closet, (3) facility, or (4) warehouse.

Commentary "The concern in kitchens, storage rooms and similar spaces may be subject to locking or blockage of the exit access path. This is not a general provision for all Group S occupancies; therefore, it is not the intent of this provision to address the situation of egress for offices through an associated warehouse space."

2015 Commentary, F-1,S-1 Are moderate hazards, S-2 & F-2 low hazards, therefore the B occ. is more hazardous


Please note that Table 508.4 contains groupings of
some of the occupancies, including:
• A, E
• I-1, I-3, I-4
• R
• F-2, S-2, U
• B, F-1, M, S-1
• H-3, H-4
These are occupancies that share the same level
of hazard with respect to fire safety. It is possible,
therefore, to have two occupancies that comply with
these separated use provisions that require no separation
between them. For instance, a mixed occupancy
of Groups B and M would not be required to
have a separation between them, but the provisions
for calculation of the sum of the ratios of actual areas
to allowable areas would still be applied to this circumstance.
 
Non-separated uses 508.3 would negate Table 508.4
The "B" and the S-1 are the same hazard the S-2 is a lessor hazard so the B is always permitted to exit through an S occupancy.
The office in the middle of the warehouse is the "room" and the surrounding warehouse area is the building not the storage room
A storage room is not an occupiable space where a warehouse is.
OCCUPIABLE SPACE. A room or enclosed space designed for human occupancy in which individuals congregate for amusement, educational or similar purposes or in which occupants are engaged at labor, and which is equipped with means of egress and light and ventilation facilities meeting the requirements of this code.
 
It's an existing warehouse storing many different things including tires. They are taking out the existing offices that are along one exterior wall and building a smaller office over an existing restrooms in the middle of the building to make more storage area.

. The warehouse was built before codes and has no sprinklers but they are thinking about just having sprinklers in the new office. I guess they are worried about the paper records and computers. I do not know who will be using the office.
But by sprinklering this office wouldn't it mean the office would be is less hazardous than the S-1 and you can not exit through a more hazardous space?

This warehouse area probably does not have the egress, light and ventilation requirements of the code so does this mean it is not an occupiable space?

The question is who will be in the office??

If it is the warehouse supervisor no problem

If it is the company president’s chauffeur, PROBLEM.

A warehouse in a way is already a storage room, the main office cannot exit through it,,,

But warehouse workers can,
 
You just indicated that the new office will be built "above" an existing space, will it be open to the space below as in a mezzanine?
How will it be accessed?
 
I have no control of who will use the office. There will be an open stairway from the warehouse floor to get to the office. It will be a enclosed mezzanine with mostly glass.

I understand that

But I would not approve it if anyone besides someone working in the warehouse uses that office.
 
So to clarify

We are talking about an actual warehouse? even though it is labeled as "storage room"

About how many sq ft?

And they want to add an office over an existing bathroom, in about the middle of the warehouse??


My position is the person that uses this office is "accessory to the use" of the warehouse... No Problem, such as a warehouse supervisor, or break room for the warehouse help.


If it is say a salesperson, needing space,, NO, does not normally work in the warehouse!!!!!


And this is the section I would cite::::


2. Egress from a room or space shall not pass through adjoining or intervening rooms or areas, except where such adjoining rooms or areas and the area served are accessory to one or the other, are not a Group H occupancy and provide a discernible path of egress travel to an exit.

Exception: Means of egress are not prohibited through adjoining or intervening rooms or spaces in a Group H, S or F occupancy where the adjoining or intervening rooms or spaces are the same or a lesser hazard occupancy group.
 
Except, you are placing it above a RR, there by requiring a stair to access it, there by making it an inaccessible space unless it is for security personnel only.
 
They told me they are going to rent the building out and the new tenant needed more storage space, that's why they are doing the work. The owners don't know or cares who will use the office.
 
Less than 3,000 sq ft a stair is all that is required to make it accessible.
An an office less than 10% of the warehouse is accessory and code compliant for the B to exit through any S occupancy. I don't care if the office is used by the warehouse manager, bookkeeper, salesman or any other employee of the tenant. If that is where you work every day you will be familiar with the building and exiting.

Ok

What if

100000 sq ft warehouse

Business wants to put a 4000 sq ft office space in the middle of the warehouse.

No rated corridors

If this one office is allowed,, because person knows way out

Will the 4000 sq ft office be allowed??
