2013 CBC, non sprinklered, Type 1 building; I am trying to understand the relationship between Table 1015.1 and Table 1018.1.
1015.1 states that for a "B" occupancy the maximum occupant load allowed for a space with one exit is 49 occupants. 1018.1 exception #4 states "A fire resistance rating is not required for corridors in an occupancy group "B" which is a space requiring only a single means of egress complying with Section 1015.1."
Table 1018.1 States that (in a non sprinklered building) a one hour corridor rating is required if more than 30 occupants are served by the corridor.
For discussion lets say that my suite is 49 occupants or less. But because of travel distance in excess of 75 feet I need to provide another means of egress. So I now have a corridor that is continuous to 2 separate means of egress that lead to a rated common area corridor, but the space only requires 1 per 1015.1. If each one of these means of egress corridors is serving half of the load, lets say 24 occupants out one door and 25 occupants out the other door does that allow me to use a non rated corridor throughout this suite area?
Tenant want all glass office fronts and non-rated corridors are the ticket, just a little confused if my logic is accurate.
Years ago here in San Diego they actually had something they called "interior tenant corridor" and as long as every suite exit had less than 30 persons exiting into the rated common corridor the interior tenant corridor did not have to be rated and the suite could be quite large, in excess of 49 for sure.
Is this a similar concept, but now I am limited to 49 occupants in the entire suite area?
Addition of sprinklers is not an option.
