A tandem garage is a type of garage where two or more vehicles are parked one behind the other instead of side by side. The width of a tandem garage is usually the same as a traditional garage, but it is deeper to accommodate the additional vehicles. There are different types of tandem garages, including two-car and three-car tandem garages. Two-car tandem garages are standard as both attached and detached buildings, while three-car tandem garages have two garage doors with space behind one of the bays for a second car. Tandem garages are a smart use of space and are ideal for narrow tracts of land where there is not enough space for a standard two-car garage. However, it is important to note that not all areas allow for tandem garages to be built.
