[Kax]

A home base implies very strongly a place that's safe and both stores and supplies (if it's not just your own hidey-hole) equipment and food.

Which makes it a patron.

That same can be done with a company you own or part-own. (which makes me think of doing that for my players, as they have people for organising party stuff, so a Patron 'corporation' comprised of thermselves and their staff is valid)

But there are other uses; per above, check the Supers rules for bases.
