Question
Does the Code allow a bathroom exhaust to terminate at the interior side of and exhaust through a vented soffit?
Answer Published 08/18/2021 at 7:43 AM
No, M1501.1 clearly does not allow discharge to the soffit
Commentary
Additionally, M1506.3 states that openings shall comply with Sections R303.5.2 and R303.6. The exhaust opening sizes found in R303.6 would not be provided by vented soffit, and therefore must be vented to the required grill or louver. Additionally, R303.6 requires the termination to be outdoors, which would be in opposition to terminating the opening within the soffit confinement.
