Bingo... Well said .... Would be nice to always have prescriptive formula but truth is that sometimes a principle has to look at a formula and say you are the least not necessarily the best...Kinda like the low bidder

But look at the difference in the design of an Ace Hardware vs a Home Depot. 99% of the products either store sells is available in both and one is designed to .2/1500 and the other sometimes at 1.6/1200 in effect. If you see Lucy, tell her she has some splainin to do!! But in reality, it's not the oil filter or the wedding ring, it is the fact that Ace has a lay-in ceiling at 12 feet above the floor and everything on shelves seven feet high or less, and HD has a roof at 28 feet and a warehouse stored above a retail store. So you would be correct to say a Home Depot is a retail store, but it's also an S 1 occupancy in accordance with IBC. Clear as mud?

To the NFPA 13 fundamentalist, they are both mercantile (which, incidentally, is an adjective - my guess is that the rest of the occupancy descriptions in NFPA 13 are nouns) so therefore OH2.
