What do you mean by "house panel". Each condo unit has its own circuit panel box on its outside wall.

Usually condos have some common area lighting, eg security lights, parking lot
lights, street lights, that are run off a meter paid for by the condo.
In your case it appears there is a common garage area, so it sounds like
that lighting would be on a house panel. Otherwise if it's a garage for
say 6 cars, who pays the electric bill?
