Thanks for the continued replies and encouraging comments. I'll try to answer some of the questions:
1) "Where are the beams that hold up the second story?" Well, there isn't a "second story" per se. The finished room over the 2 car garage and the storage area over the 4 car garage will have several support posts. Look at the concrete "footings" where the posts will be:
2) "Make certain that your garage door tracks raise all the way to the ceiling." Yes, they will but this point is really moot. I'm not crazy enough to put 4 lifts in the 4-car garage. Imagine 8 cars in that section of the garage?

Only the innermost or "deeper" 2 car bays will have lifts. They'll be deep into the garage, so the door height is irrelevent.
3) A "minimum of 12 feet for a 4post car lift? That's a little generous, unless you're talking about a truck/SUV. The cars going up on my lifts include a 2001 Acura Integra Type R and a 2000 BMW Coupe. I think 11 feet is plenty.
In fact, when I look at the developing framing around the 4 car garage, I'm pretty shocked how high it's really going to be!
(By the way, please ignore the blue surgical boot covers on my very pregnant wife's shoes. I didn't want to get mud in my Subaru! )
