    Type IB - rated floor assembly required over crawl space?

    Hi! We are proposing a Type IB, type R-1 single story hotel, that is non-separated. The units are prefabricated and placed over an unoccupied crawl space, will the floor assembly need to maintain a 2HR rating per Table 601? or are there any exceptions to being over a crawl space over grade?

    Accessory Rooms within Rated Corridor/Lobby?

    Can an enclosed office be considered an accessory space and not rated within a rated lobby? See attached. We are proposing a rated corridor connecting to a rated lobby, and not wanting to rate the glass/windows into the office. Thanks!
