Retrofitting Automatic Fire Sprinklers on Townhomes

[Leland S.]

Is anyone familiar with the requirements of the IBC to provide automatic sprinkler systems? I wanted to know if it's feasible to bring lines in for sprinklers to existing townhomes. They are built with open trusses, so water lines could be brought in from the side of the building straight through each ceiling opening. I'm not sure what else is required for these lines or if they just come straight in from the road with a cutoff like regular water mains. Coming through the slab foundation at this point is not possible, but I do have an HVAC closet or laundry room I could put shutoff valves in if they are required to be indoors.
