Not if its closed.
In some places it is not permitted for a repo man to enter a closed garage. In California, for example, a repo person can come on to private property to locate and take a vehicle, but cannot enter a locked placed, can't go inside the house, can't threaten or bully. This is not universal. In some areas the repo man can break open locks, etc.
Not if you tell him no nicely.
yes if it is open
he cannot break & enter to get the car.
yes they are allowed on your property hide it in the garage if you have one
Well yes, But if you lock your garage then the repo officer will have to come to your door in order to get the car.
No, repo persons can not enter your residence without permission and an attached garage is your property.
It is NOT legal to enter a garage in any state to repo a car, unless the repossession agent has a replevin order issued by the court that holds jurisdiction. Call a local attorney.
Probably not. If the garage is locked and the repo agent must break the lock, then that is breaking and entering. Even if the garage is unlocked and the act of opening it can (in some areas) be considered breaking and entering.
Yes. he cannot break & enter though.
