Shed structure indoor or outdoor classification

[nicolai]

Hi Folks
as what is an IBC storage area cover with an overhead roof (but not on the side walls) classified outdoor or indoor
I am considering a sprinkler system in accordance with NFPA 400 and NFPA 13

for fire sprinkler protection at appear no other choice than deluge sprinkler over entire area ( automatics sprinkler with glass bulb will not result in reliable detection activation due to open side of shed.)
Deluge system will have drastic impact on the water demand

I did not check the rest of the book

But unless there is something else in IFC or local requirement check your IFC edition for this

5004.13 Weather Protection
Where overhead noncombustible construction is provided for sheltering outdoor hazardous material storage areas, such storage shall not be considered indoor storage where the area is constructed in accordance with the requirements for weather protection as required by the International Building Code.
