I have two buildings on one site.
The main building is 65000 square feet two stories Type II B.
The second building is U occupancy - 1000 square feet. Also Type II B.
Scenario A- Combining both under one building. This eliminates the fire separation requirement between the two buildings.
The combined square footage after considering the frontage addition falls under the allowable total for the B occupancy structure. The code does not explicitly state that the total allowable should be based on the more restrictive occupancy. Would U be considered the more restrictive occupancy?
Scenario B - If we consider them as separate buildings then the fire separation code requirements do apply.
So I draw an imaginary line between these two buildings. I place the line on the exterior wall of the main Type IIB building. This wall is concrete with a four hour rating.
Now if the U occupancy building is less than 5' from the imaginary line then it needs to be 1 hour rated and 0 hour rated if 10'.
I want to confirm that BOTH BUILDINGS NEED to adhere to the fire separation requirements.
