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.

    For more on dryer venting, see our blog posts What is the maximum length for a clothes dryer vent? and Why is it bad to have a clothes dryer vent near an air conditioning condenser (outdoor unit)? and What are the code requirements for an outdoor dryer vent cover?
