This table has the same occupancy types listed across the top and down the sides and for the most part makes sense. I'm confused about the discrepancies when you get to H occupancies. If I go down to H-3/H-4 then over to H-1 a 1 hour separation is required if the building is sprinklered. If I go over to H-3/H-4 then down to H-1 it's NP, not-permitted. If I go down to H-5 then over to H-2 then no fire rating required if it's sprinklered. Over to H-5 then down to H-2 1-hour rating is required. Do you always go over first, then down? Does this imply, for example, that if you are designing or working on an H-2 (sprinklered) with an H-5 next door then no separation required on your side. If you are on an H-5 (sprinklered) job with an H-2 next door then you are required to do a 1-hour wall? Thanks!
