Maybe [F] 903.3.1.2 NFPA 13R sprinkler systems. Automatic sprinkler systems in Group R occupancies up to and including four stories in height shall be permitted to be installed throughout in accordance with NFPA 13R.
However, and as noted in the commentary; "it must be noted that although the building would be considered sprinklered throughout in accordance with NFPA-13R, NOT ALL OF THE CODE SPRINKLER ALTERNATIVES could be applied. Any alternative that requires the installation of an NFPA-13 system would not be applicable if a portion of the building utilizes an NFPA-13R system." Again aside from 510 special provisions........... 504.2 Building Height - 903.3.1.1 NFPA-13...........Except Group R - 13R recognized, 20 Feet, 1 Story with a maximum 4 stories and 60 feet. 506.3 Building Area Increase - 903.3.1.1 NFPA-13 508.4 Occupancy Separation - 903.3.1.1 NFPA-13.....however designer could still have separated occupancies with 13R utilizing the non sprinklered column and a 2 hr separation. Theres more....................
