Can a clothes dryer vent in a mobile/manufactured home terminate in the crawl space?
Monday, March 15, 2021
No. The HUD-code specifically bans dryer duct terminations in the crawl space under a mobile home: “Dryer vents and combustion air inlets must pass through the skirting to the outside,” per [24 CFR 3285.505(f)]. The diagram above shows the details of two approved ways to run a dryer vent, either through the wall or the skirting.
Besides being a HUD-code requirement, it’s also the sensible thing to do to avoid dumping gallons of water in the form of hot/damp air into the crawl space. And the dryer lint that collects on the ground is also highly flammable.
