You will have to coordinate with the host when you want to access the space.
Multi Level Garage space unused. I would allow easy access to this space with your own garage remote. With my two car garage I do not use half of my space meant to store personal belongings behind my car. There will be a car parked in front of your belongings. The space it broken up by a divider and has two levels. This garage is always locked and will be next to my personal belongings (piece of my mind knowing I would always want to lock up this space) .
