residential sprinklers are allowed in a 13 system. So, if you use
residential sprinklers in the dwelling units and adjoining corridors,
you should be fine. I am afraid this one will get into a battle with
the plan reviewer. I live in this jurisdiction and try to get along
with the reviewers, but sometimes, you just have to stand up for your
customers.

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.

Subject: Residential Sprinkler in I-2
Is there anything in NFPA 13 that states you can NOT use residential
sprinklers in an I-2 occupancy? 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*.
