You are getting a traditional ceiling mounted opener, the minimum height is around 9’3”. You can get what is called a “low headroom kit” but if you are building new, I would not recommend that. If you get a direct drive wall mounted opener you will need at least that, preferably a little more because of the slope required on the horizontal portion of the track. Either way, at least 9’6” should be adequate for hanging supports.
