Bathroom fan code?

ChrisJChrisJ Member Posts: 8,627
This feels like a dumb post but I like to do things the right way.  I'm installing a fan in our main bathroom as it doesn't have one.



Are there any codes I should be aware of?  8x10 bathroom with a tub\shower and I'm planning on a 110CFM fan vented via 4" flexduct via a damper on the roof.  Fan will be controlled by a 3 switch control for light, fan, night light installed by the door and out of reach from the tub.

    bathroom ventilation considerations

    Based upon the 2009 IRC:

    min. 50 cfm intermittent ventilation or 20 cfm continuous

    must discharge directly to outdoors--not attics, garages or crawlspaces

    flex duct flame spread 200 or less

    joints sealed with UL181 B-FX tape or 181 f-M mastic

    three screws equidistantly spaced at connection to flanges

    seal penetrations per energy code

    fireblocking per R302.11

    corrosion resistant screen, grilles, or louvers

    outlet protected from direct weather

    one wall switch controlled light-may be occupancy controlled
