A garage is a place for storing cars. There are many kinds of garages used for different things.
Residential garage change
A residential garage is a garage that is part of a house or similar building. Some garages are directly connected (called "attached") to the house, while others are separate and called a "detached" garage". The garage will have a large garage door that opens to let cars in and out, which is often opened by a motor.
Parking garage change
A parking garage is a large covered structure, often made of concrete, which is used for holding many cars. Parking garages may have more than one level.
Automobile repair shop change
An automobile repair shop may also be called a garage, although it is for repairing cars rather than just storing them.
