Section 903.2.8 requires that sprinkler systems be installed throughout all buildings with a group R fire area. The commentary supports this by clarifying that the sprinkler requirement is for the entire structure not just the R occupancy.
In mixed used commercial, mercantile and Business space with a new introduced/ converted R occupancy is there a provision that allows us to divide the building with fire barriers or fire walls to only sprinkler the R area?
A Fire wall would easily divide a structure into two distinct halves. For purposes of converting an upstairs business suite to a residential use, a fire wall is not practical. Sprinkling the entire building due to a small portion of newly added Residential space may also be impractical.
Have you encountered this any what options were discussed? Thanks for your input
