If the wall between the house and the garage is NOT insulated, there may be some benefit realized by insulating the garage ceiling.
Bottom line.....If you don't insulate the garage ceiling, (most contractors do not) it seems to me that insulating the wall between the garage and the house would be beneficial. Perhaps, more beneficial then insulating the the garage ceiling.

Whether your exterior wall is insulated depends on if you have stucco or vinyl siding. When installing the stucco, they use concrete blocks and polyiso foam insulation with a foil sheathing. The entire combination of the concrete, stucco and the foam insulation should total R13. That is the code. If your house is vinyl siding then they use a felt black backer board and in between the wood studs they use R13 fiberglass. Not sure now if they are installing the foil backed polyiso sheathing or not.
