Point of clarification: The space is NOT a "built-out back part of a garage", but rather a separate downstairs 300 sq. ft. room with full bath at the bottom of the center stairwell. You must walk through a short hallway to reach the separate 2-car garage. The doorway from the room to the hallway is kept locked for privacy, both for guests and for us who live in the main house upstairs. The Airbnb space has been created to have a separate and private entrance, which is entered via a private patio entrance bordered by the outer garage wall.
