The NFPA 13 & IBC occupancy classifications approach things very differently and they are different systems.
While the building code does have a separate system for Types of Construction where combustibility of the structure [not the contents] is a factor, its occupancy classification system is based on factors not contemplated by NFPA 13. Such factors that are not part of the NFPA 13 classification system include: 1) whether the occupants are capable of self-preservation[Institutional], 2) whether large numbers of occupants are present [Assembly], 3) whether people use it for sleeping purposes [Residential], etc. A good example of the difference of these two classification systems can be found in the building code's High-Hazard Occupancies in Group H. While a fire protection system is generally required for all Group H occupancies, the NFPA 13 occupancy hazard classification will vary depending on the fire hazard the contents of the building pose, not other hazards to the occupants. The sub-categories of Group H vary with the hazard: 1) a detonation hazard[H-1], 2) a deflagration hazard [H-2], 3) a physical hazard [H-3], 4) a health hazard [H-4], or 5) are a hazardous production material (as in semiconductor fabrication facility) [H-5] So for one example, look at H-3 and the definition of physical hazard, and you will see that a building area could be H-3 due to a chemical which is either a combustible liquid, a cryogenic fluid, explosive, flammable, organic peroxide, oxidizer, oxidizing gas, pyrophoric, unstable (reactive) material, or a WATER-REACTIVE material. For another, consider that the H-4 health hazard includes chemicals that are toxic, highly toxic, and corrosive. I think you can see from the above example, a variety of fire hazards and levels of fire challenge are possible in the Group H occupancy, and within each subcategory of Group H. I don't have time to give a contrast about how storage is treated in each code, but it could be a good example too. It would be best to treat these two classification systems as the separate independent systems they are... I hope this helps y'all, sorry for a late reply... Respectfully, David W. S.

There is no correlation IMHO. That's like saying we ignore 5,000 sq.ft. of rack storage of the plastic packaging where it's in the 100,000 sq.ft. metal widget factory. Protect the hazard not the occupancy classification out of a document that is irrelevant to sprinkler design. Ask the question in an exiting forum and now I'm with you. To the question, I could go either way. Though strong lean to OHII because it may not be a salon for long. Then what is the owner going to do when a real mercantile comes in. I haven't been to one in a while. Aren't there still aerosols? How about the stock room, assuming they have one? If it's truly light amounts of products and the owner understands limitations I could go along with LH.
