This sample uses fixed example content so you can see the structure of every finding. Nothing here was generated from your photos, and it is not a compliance determination for any real installation.
The flexible duct in the photo runs upward past the ceiling plane and ends without a visible wall or roof termination fitting. Clothes dryer exhaust must be carried fully to the outdoors with a listed termination and a backdraft damper; discharging into an attic introduces moisture and lint accumulation, which is both a mold and a fire concern. The duct also appears to be flexible foil rather than smooth-wall rigid metal, which increases friction loss and lint capture over the developed length.
IMC / IRC-M — IMC 504.4 (exhaust termination) and 504.6 (duct material and length)
Extend the exhaust with rigid, smooth-wall metal duct to an approved exterior termination with a backdraft damper, support the run per manufacturer instructions, and confirm the total developed length against the dryer listing. Verify the adopted mechanical code edition and any local amendments with the AHJ before rough-in re-inspection.
