I'm working on an R-4 occupancy project, a half-way house. The second floor has 6 bedrooms (1228 s.f.), so 6 occupants. If I look at building code sections 1021.1 and 1021.2 there seems to be no exception to an R-4 occupancy needing 2 exits from the second floor. The only exception I see for an R-3 occupancy is 1021.1 exception 3 which allows one exit when equipped with a sprinkler system. This doesn't seem logical when an R-2 occupancy can have 4 dwelling units on the second floor with only one exit. Anybody have any thoughts on this?
