Why in the garage??? Why not outside?? You can put the meat on and run inside if you don't want to wear a coat....but around here people grill outside all year long....even during a snow storm.
I would worry about the smoke and grease and perhaps carbon dioxide in the garage....if you didn't leave the door open.

We always keep our grill in the garage and just wheel it out the door in nice weather and in snow or rain, keep it right in the open doorway. You can stand inside and stay dry, but you'll definitely need a coat, LOL. There's nothing more fun than grilling chicken in a snowstorm! If you have a station wagon, just open the tailgate and there's your seat :-)

I am originally from the UK and most the grilling we ever did was standing in the garage..............

Grilling in the garage sounds a little too much like a recipe for carbon monoxide poisoning, to me...

The grill would be at the outside of the open garage door.

There are just too many variables involved (gas "tightness" of house, house volume, garage volume, topology of home site, house configuration, wind direction, burner efficiency, lung efficiency of people, durations of the cooking event and many more) to answer your question. In many, perhaps most, situations its perfectly safe, in others it will be lethal.

Have you considered building shelter over the grill, like a picnic pavilion or gazebo for use in adverse weather. Having grown up in the central Adirondacks I understand NY winters, and would rather sacrifice my comfort in the sub zero temperatures then risk my family's lives.

Garage door open or closed, if you do very much of this every suface inside will soon have a greasy coating on it.

Thanks for your responses. I guess it was a bad idea.

I don't understand why people think they need to stop grilling in the Winter. My Weber sits in the same spot outside year-round and I grill year round. I'm in Minnesota so I know all about the snow and cold. I keep the grill covered with the factory grill cover when not in use. Works great.

Please don't see me as a hard butt, but rather someone who cares...do not even think about grilling inside the garage (door open or not) due to the carbon monoxide issue. This potentially has deadly results.

I live in the Pacific Northwest (Seattle) with lots of wind and rain yet I still use a grill on my back deck. Like Lindac ...a little grilling a dashing out of rain or snow is no big deal. Exciting, yet safe. Otherwise, get one of those canopy thangs that have a cover but open sides.
