IBC 2009: 903.2.6 Group I. An automatic sprinkler system shall be provided throughout buildings with a Group I fire area.
Exception: An automatic sprinkler system installed in accordance with Section 903.3.1.2 or 903.3.1.3 shall be allowed in Group I-1 facilities. 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. 903.3.1.3 NFPA 13D sprinkler systems. Automatic sprinkler systems installed in one- and two-family dwellings and townhouses shall be permitted to be installed throughout in accordance with NFPA 13D. [F] I haven't thought this through completely, but interesting enough, the exception only permits 13R and 13D for I-1. However, 13 permits residential sprinklers.

We have done these many times, but I am getting rejected from a local AHJ that says you can't use residential sprinklers in an I-2 occupancy. This is an identical building to a project that was done about 3 miles away in an adjacent jurisdiction without any issues. I have presented him with: 6.2.4.1 Residential Sprinklers. *Residential sprinklers shall be permitted to be listed for portions of residential occupancies as defined in 8.4.5.1.* 8.4.5.1* *Residential sprinklers shall be permitted in dwelling units and their adjoining corridors, provided they are installed in conformance with their listing*. 3.3.8 Dwelling Unit. One or more rooms arranged for the use of one or more individuals living together, as in a single housekeeping unit normally having cooking, living, sanitary, and sleeping facilities. For purposes of this standard, dwelling unit includes hotel rooms, dormitory rooms, apartments, condominiums,*sleeping rooms in nursing homes, and similar living units*. -- Please feel free to call if you have any questions or comments.
