What is a Tandem Garage (Pros & Cons & Layout Designs)

Here we answer the question what is a tandem garage and share different layout configurations and designs. Tandem is a word that means one behind the other. This will make sense with the idea of a tandem garage, a garage where one car will fit behind the other.

A tandem garage is similar to a traditional garage, but it will include space for two cars longitudinally versus the traditional lateral. The width will remain the same but there will still be room for two cars, one in front of the other. This is used in cases where there is not enough room to build a garage out to the sides and have to go deeper into the site.

Typically, these types of garages have one door for vehicles to exit and enter, which can cause one car to be stuck if there is another behind it.

In some cases, there will be two garage doors, one placed on each side of the room, allowing a car to enter or exit from either side not disturbing the other car in that garage. This can only work if the driveway layout allows for two point of exit or entry to the garage, which most do not.

Types of Tandem Garages

Two of the most common types of tandem garages are the two car and three car tandem garages. These can be incorporated in many different types of homes and settings. The actual garage dimensions can vary depending on the type of home and its size.

2 Car Tandem Garage

A two car tandem garage will allow for two cars to be park linearly. These garages will have the width of an average one car garage with double the length, allowing space for two cars.

Sometimes the space is used for one car and the rest for storage. Other times two cars will occupy the space. They can have one or two points of entry and exit.

2 Car Tandem Garage Size

The minimum size for a tandem garage is 12 feet wide by 32 feet long. This is considering the standard car has a length of 14.7 feet, and providing enough room to park both cars and freely move around the vehicle without being too cramped.

For a larger vehicles or additional room for storage a 2 car tandem garage size of 12 feet by 36 feet is advised. This size is better for those who want a work bench or space for tool storage.

A standard two car tandem garage has a square footage of 384 for dimensions of 12 ft by 32 ft, or 432 square feet for the larger 12 ft by 36 ft dimensions.

3 Car Tandem Garage

A three car tandem garage will look on the outside as a traditional two car garage, with two cars placed horizontally. To add the space for the third car, one of the sides will be deeper in the same way that the two car garage is set up.

This can also be used as two parking spaces and a storage or workspace, or park all three cars inside. This type of garage can also have multiple doors if so desired and if space is available.

Three Car Tandem Garage Size

A standard three car tandem garage measures 24 feet wide by 36 feet long at its widest. The main two car portion is basically 24 feet wide by 20 feet long, while the smaller one car section measures 12 feet wide by 16 feet long.

4 Car Tandem Garage

The standard 4 car tandem garage has the appearance of a standard garage, but is deeper allowing for additional parking spaces. A four car tandem garage can fit two rows of cars, side by side in front, and side by side in the back.

A four car garage is typically found in detached buildings and can provide a substantial increase in the home’s value.

4 Car Tandem Garage Size

A four car tandem garage should have a minimum layout of 24 ft wide by 38 ft long. This allows for the minimum space to enter and exit a standard vehicle without much room for storage.

A more spacious layout for a four car tandem garage would have dimensions with a width of 28 ft by 40 ft in length.

Pros and Cons of Tandem Garages

As with any decision there are pros and cons to selecting a tandem garage for your home. Some are as follows.

Pros of getting a tandem garage can really be appealing. Tandem garages are very good for narrow sites, if a two car garage is needed and there is not enough space width wise, this parking layout is the perfect option. This will also save space altogether which builders may want to do to increase their profits of a certain building.

Having a tandem garage will also make it so that less space is taken up by garage door. This will be more aesthetically appealing than multiple garage doors. While it would be the most common idea to fill the space with cars, tandem garages could also create extra space for a work zone or garage storage space if only one car needs to occupy the garage.

On the contrary, there are some disadvantages that could make you think twice before jumping into a tandem garage situation. The most obvious and most important drawback will be the fact that most tandem garages only have one point of entry and exit, and the cars will park one behind another.

This will mean that if the front car needs to leave, the back car will need to be moved from the garage to let them leave. This can be troublesome in situations such as apartments or somewhere with lack of communication between users of the space. This can even be difficult if communication is available, just timing may not be on anybody’s side.

For some people the reason for building a tandem garage is to stuff as many spots into a small space as possible. This can be not an option in some places due to codes requiring certain amount of parking and it only counting as one actual parking sport with extra storage space versus two spots.

In addition to that tenants can have so much difficulty with stacked parking and tandem garages that they would specifically avoid places with them, creating a smaller market and less of a likelihood of having and keeping renters.

• Install good lighting for easy maneuvering, especially at night. A motion-activated light eliminates the need to turn on the lights when using the garage while saving energy.

• Set a schedule with the other car owner, and it is best to familiarize yourself with each other’s schedule for smooth use of the tandem garage.
