I am doing an open office renovation. Single story building, 3500 sf, Type III-B construction, unsprinklered, B occupancy, California Building Code. The intent is to keep an open feel to the space, but not create corridors or sprinkler the space. I have two exits with good separation, each with plenty of width, each opening directly from the space to grade, and travel distance is not a problem. Occupant load is 35, based on the 1:100 ratio for open office business areas. Single tenant in the space.
Question: Is a rated corridor required to connect the exits? CBC Table 1018.1 shows that an unsprinklered B occupancy with an "occupant load served by corridor" > 30 requires a 1-hour rated corridor. Since I have two exits, the "occupant load served" by each exit equals 18. However, if one exit goes down, must the remaining exit "serve" all 35 occupants, thus requiring a rated corridor connecting the two exits?
