Can I terminate my dryer vent next to my gas meter?
An opening under the building code would typically be a door or a window.
If you have a gas leak, the dryer vent nearby doesn't significantly increase the hazard of the gas leak, because the hazard of a gas leak is massive.


On the other hand, blowing hot moist air on a piece of equipment is more likely to create maintenance issues and routing a new installation is typically pretty easy, it's probably worth a little extra trouble to avoid venting directly onto the meter.
