On two separate Quality Assurance site visits in the past two weeks I've detected elevated levels of Carbon Monoxide (CO) coming from attached garages. I was a bit surprised at this since neither garage contained a car - let alone any active source of combustion. So I did some digging and came up with this great resource from Iowa State on the topic. From my reading of it, the best practice is to run a small fan to depressurize the garage.

The garages both contained cars, but not at the time of the inspection. I agree about the foam & fan run time. Personally, I would like to see the test #s on a full spray foam attached garage, since I have had clients who have spray foam insulated the ceiling deck of garages for air infiltration purposes.

Nice piece & I got to ask, was the increased level because they had cars in there earlier as the article alludes to? Pretty good points made in that piece though I think it would have been useful if they had a few garages done with foam as those are pretty well air tight. While having a fan depressurize it can help reduce the CO from a running car, it should not be running 24x7 as that will be pulling conditioned air from the house
