How Many Square Feet Is A 3-Car Garage?

Dustin Hawley | Mar 19, 2023

Today, car manufacturers cater to all types of customers and their mobility needs. The average consumer is spoilt for choice as far as vehicles are concerned. It’s not uncommon for families to own more than one car, where both primary members have a main vehicle and a secondary one, like an off-roader for weekends and holidays.

How Many Square Feet Is A 3-Car Garage

To accommodate all the vehicles, it makes sense to meticulously plan the garage so that it may act as storage space and, perhaps, a place to keep in touch with your woodworking hobby. In any case, let’s get into the topic and see how large a 3-car garage can get and what goes into building it.

Understanding The Space Requirements For A Car Garage

Knowing the space requirements for a car garage that can hold more than one car is vital for several reasons:

  • Cost Efficiency. Proper planning can also minimize construction costs. By ensuring that the garage is the correct size for the number and size of cars it will hold, there will be no need for costly adjustments or renovations in the future.
  • Safety. Ensuring a garage is the correct size for the cars it will hold can help promote safety. Cars that are too large for the garage may have difficulty fitting in and out, which could lead to accidents.
  • Functionality. Knowing the space requirements for a car garage helps optimize functionality. Ensuring the correct size makes it much easier to include whatever you want and plan for a workshop or additional storage space inclusion.
  • Aesthetics. A properly designed car garage serves as storage space and enhances the property's aesthetics. A garage that is too large or too small can look out of place and be a sore spot for the eyes.

3 Car Garage Size

The size of a 3-car garage will vary depending on the dimensions of the cars and the layout of the garage. A typical single-car garage is around 10-12 feet wide by 20-24 feet deep, so a 3-car garage would need to be significantly larger.

A rough estimate for a 3-car garage would be around 36 feet wide and 24-36 feet deep; however, it could be larger or smaller depending on the specific design and layout. When it comes to square footage, it should be around 864-1296 square feet. 

Most homes in US suburban areas come with a standard 2-car garage. So if you plan to move into such a house, you’ll need to redesign it to fit three cars, and some advice will help.

Things To Consider When Planning Out A Multi-Car Garage

When designing a garage that can hold more than one car, there are a few things that you should consider:

  • Size and dimensions of the cars. The size and dimensions of the cars that will park in the garage should be considered when designing the garage. This will ensure that the garage is large enough to accommodate the cars and that there is enough clearance to move in and out of the garage safely.
  • Layout. You should design the layout of the garage in a way that maximizes the use of space. This can include using storage shelves, cabinetry, or other organizational tools to maximize the space in the garage.
  • Access. Design the access to the garage in a way that is convenient and easy to use. The plan can include automatic garage door openers or multiple doors to improve access to and from the house.
  • Future needs. Consider the future needs in terms of adding another vehicle. If you plan to use the space for some other activity or purpose, like a workspace, you’ll need to plan for additional space and add electrical outlets and lighting.

Summary 

Proper planning of a 3-car garage will not only ensure that it will serve its purpose of safely holding your cars but also be cost-efficient and add to the aesthetic value of your house. On average, a 3-car garage can be from 36 x 24 feet or 36 x 36 feet, but the actual area depends on factors like layout and type of cars parked there. A well-designed multi-car garage should be accessible and planned correctly to avoid accidents and have enough space for future projects you might devise.
