Another option is to provide a reinforced concrete pit or depression under the car and put the lift posts in it as well. You can cover the pit with checkered plate or grating when not needed. If starting from scratch, the cheapest, best option is to just build a garage with a ceiling height that you specify taking into consideration the lift height and car height along with how much room you need to stand underneath. Pass the requirements to your contractor so that he can plan on all requirements you have and any other items needed like lift foundations and anchors (they would just thicken the floor slab at the post locations), conduits, electrical requirements, lighting and any embedded items. I would also consult with your lift provider like Bendpak.
