There's lots of good, interesting info in this thread.

The other side of the wall is a bedroom.

So, with the door I’d be able to access the attic from the bedroom, instead of using the pull down stairs in the garage.

Others have suggested putting the door to the right. That’s possible, but would be inconvenient because I’d have to move a desk anytime I wanted to open the door.

OK, good to know. It sounds like the guys think it would be OK to put a door there.
Is your garage air conditioned and heated? If not, unless you live someplace super temerate, I'd be insulating that wall to the bedroom. And like John said, make sure that door is air tight.
