In the EPA’s study on Building Codes too Indoor Air Quality, on Page 17, the agency recommends attached garages live ventilated alongside a 100 CFM ducted or an lxxx CFM un-ducted exhaust fan.
This fan should be designed for continuous functioning or go on an automated system and so that it turns on when the garage is occupied in addition to stays on for an hr afterward it is vacated.
