If you're in California (and some other states as well), amendments require that all such systems be per 13. Residential sprinkler provisions still apply, but the design must be based on NFPA 13.

I was playing from memory and thought it was more optional verses a SHALL. Back to the question on type of system. I'm starting with the premise that 903.2.8 dictating protection per 903.3 allows any type of system that complies with the scope of the standard. Since the scope of 13D is for one and two family dwellings and not residential occupancies, it does not cover assisted living facilities. The point to be made is that a large I-1 can use a 13D (due to the IBC exception) so a smaller I-1 that has been assigned a less demanding occupancy classification is quacking like the same duck regarding needed level of protection. Since it is not stated that way in the IBC, one has to discuss equivalencies with the AHJ.
