Room Beside or Above Garage

Some homes may be built with a room located on top of the garage or beside the garage. It is important to realize that homes with attached garages are often found to have a higher level of benzene and other airborne chemicals indoors.


  • Check for any openings or leaks between the garage and the home. If any entry points are detected, seal them properly. If possible, move the room away from the garage
  • You may choose to install an exhaust fan to better ventilate the garage. This will help limit the level of harmful gases from getting into the home.
  • Install a carbon monoxide detector in any bedroom located adjacent to the garage. Ensure adequate ventilation is available especially in that room to prevent high levels of carbon monoxide from building up over time.
