BFE in that area is 16 feet - our slab is going to be at elevation 2-3 feet so we're going to have about a 14' high garage! (with break-away walls, no less). We decided that some sort of elevator would be a must, so last night we did some research. Here's what we found out:
First, residential elevators are EXPENSIVE, no matter what you choose. There are different types: traction, roped hydraulic, and winding drum. These all look pretty traditional. What really caught my eye is a newer technology called a pneumatic vacuum elevator.

It looks like one of those tubes at the bank drive-thru and works pretty much the same way...only instead of shooting up the tube, the cab goes about 30' per minute - not too bad.
I would feel like Jane Jetson every time I got in :o)
It will be interesting to see what we end up with.
