"Surprised there isn't a law or county code enacted to seal attached garages. I sure don't like bedrooms over garages...these huge master suites."

No big deal if you don't leave your car running. That really doens't happen too often, does it?

Well sometimes people foolishly warm up the car in the dead of winter...and that's not safe under the conditions we've described...even with the garage door open.

Carbon monoxide fumes can still drift up into the bedrooms.
