If you own a civil aviation aircraft, you would be based at a specific civil aviation airport or airfield and you would have to rent a hanger there. Commercial airlines usually keep their aircraft in service for 30+ hours at a time (switching pilots of course.) When they do go in for maintenance inspections, the airline would pay to use a hanger at a larger passenger airport.
Unless it is a service vehicle that is in use for maintanence, you should never park directly in front of an aircraft.
A control tower that controls aircraft landings and launches and where they park.

Smaller aircraft will park on a "tie-down" which usually has a set of three ropes for literally tying the aircraft down. Larger aircraft park at a "gate." The large paved area around the gates and tiedowns is called a "ramp" or "apron". Buildings in which aircraft are parked are called "hangars." Helicopters takeoff, land and park on "helipads." It is common practice for small and mid-sized airplanes to disembark their passengers on the apron and then be towed or taxi or to a tie-down or hangar.
