And many people including me in one of my garages decide the risk is worth the benifits. But if it is against code it doesn't matter if it passed inspection or not an insurance claim involving the stove will be denied.
If you are ok with that risk that is up to you.
You mean against code by being a certain height off the floor?
When I spoke to the inspector he was well aware that what I was talking about was a 'detached garage' so I doubt if it's written in the code books that it can't be done where I am. I've followed all the requirements for installation. I never saw anything about height off the floor.
