1A, non-separated mixed use building under 2009 IBC. Four floors will contain only hotel guestrooms and four floors above that will contain only condominiums or apartments. Access to each from the ground floor is by way of separate lobbies. Would the occupant loads of either (or both) lobby be calculated on one of the assembly functions of Table 1004.1.1 rather than the residential function? Unfortunately I thought to ask this question from home so I don't have the square footage of the areas in question. I can tell you that the condo/apartment lobby (which also includes a vestibule against the weather) is relatively small and won't include furniture. It is possible that the mailboxes will be located there but that hasn't been determined. Otherwise, it's only going to be used for people to stand while they wait for the elevator. Even if it were 800 SF, at 5 SF/occ that would result in an occ load of 160 and would require two exits. That's absurd. The hotel lobby may be another matter. There will likely be sofas and chairs set up for people to "assemble".
