In my opinion, the question isn't directly an NFPA 13 issue but rather
Building and Fire Code issues in terms of occupancy and allowable amounts of
chemical or hazardous materials within a control area. Normally, the code
exempts (to a degree) mercantile occupancies where products containing
flammables, combustibles or hazardous materials (irritants, toxics,
carcinogens, etc) are stored in the same containers they are sold in.
That's why Costco, Sams, BJ's and similar can store more vegetable oils in
quantity than a manufacturing or storage use building could have in storage
of a product with the same flash point.
That said, at some point in the process of analysis someone has to decide
what the corresponding NFPA 13 occupancy use group or commodity and storage
arrangement is, so sprinkler design criteria can be established... I
suggest this is a job for a consultant or an engineer of record - not the
contractor. (again - just stating my opinion)

Subject: Occupancy
I am working on a project that doesn't have an Eng of Record. The building
contains large individual shell spaces. The original sprinkler system was
designed for a mercantile occupancy. A tenant has purchased a couple of
spaces and is opening a beauty/hair salon. I don't see the fuel load as a
normal mercantile occupancy would have. Light or ord. Please comment.
