    venting of public restrooms

    I am bidding a remodel job on a convenience store with two public restrooms.

    mens- 1 urinal and 1 commode, 10' x 12'.
    womens- 2 commodes, 10' x 12'.

    They want to use one roof mounted exhaust fan for both restrooms. the fan will switch on with the lights with a occupancy sensor.

    I can't find my code book at this moment. Thanks BSC

    I believe it is 2 CFM per square foot of floor area

    I was thinking the code was 70 CFM per commode & 50 CFM per urinal, but I am not for sure. BSC

    international mechanical code says 75 cfm per fixture (whether it be toilet or urinal).
