^Agreed. The Enterprise
was commissioned from the San Francisco Fleet Yards. I'd imagine that any other ships that were built there probably had access to the station just as the Enterprise
refit team did. Given the way the structure is organized, I wonder it had living quarters in addition to the office space we saw when Kirk beamed to the station. There would have been a point in time during the refit when the Enterprise
wasn't habitable. It would have made sense for members of the crew to be stationed nearby in the event of an emergency. I suppose some of them could have stayed on Earth, but the station would have been another option.
