NFPA 13 8.15.3 and 8.15.3.2 Contract FP drawings show sprinklers only at the top of the stairwells....we did put one under the lowest landing. I honestly never really questioned it until now...
They bult the stairs out of wood and put 2 layers of 5/8" gyp board around them everywhere except the landings and treads. The landings get a durarock type treatment while the tread are getting sovered by carpet. IF the building dept declares these are acceptable as non-combustible construction - does NFPA 13 agree? If the tread were covered in a material that was most definitely non-combustible such as concrete woudl it make any difference?
