Due to factors like larger families and the desire for more storage space, the demand for multi-car parking garages has been on the rise. And with proper planning and correct dimensions, you can convert the entire buying process into a smooth journey. But first, the local codes. Since four-car metal garages are large spaces, you will need to know the maximum square feet allowed for a dwelling unit.
The next thing to consider is the design and the layout – whether you want side-by-side or tandem parking. Decide accessories like vents, insulation, and others for airflow, moisture control, and easy access. With this information, you can easily install a multi-functioning garage space.
Four Car Garage Construction 101: A Comprehensive Guide
1) Planning
1.1) Size: How big is a four car garage?
The usual size is about 48 ft. x 20 ft. [for side-by-side parking] and 24 ft. x 40 ft. [for tandem parking]. You can choose a larger size, such as 30 ft. x 40 ft.; 50 ft. x 60 ft.; or 40 ft. x 50 ft. You can compare 40 ft. wide building pricing & features, and options like customization & durability for parking four vehicles. The extra space can be your workshop, home office, personal gym, or storage area for household stuff.
Wondering what is the minimum size of a 4-car metal garage? Minimum dimension is 40 ft. x 18 ft. [side-by-side] and 20 ft. x 36 ft. [tandem]. And how many square feet is a four car garage? 800 square feet is the average size of a 4-car parking garage, but you can choose a larger one that has extra storage space.
1.2) Layout
Since a modern 4 car garage can hold four vehicles, you can choose between two types of layout depending on how frequently you want to access all your cars.
- Side-by-side parking: Here, all four vehicles are parked next to each other. This type of parking requires a wider driveway and open space to maneuver.
- Tandem parking: Here, cars are parked in two rows. To access the car inside, you need to remove the one first. It may seem a bit of a hassle, but it is excellent for a narrow driveway or if you want to use half of the garage for other activities.
1.3) Design
You can choose between all vertical/ horizontal metal garages and vertical roofs but horizontal wall panels. The benefit of a vertical roof garage is that it slides off most dust, debris, snow, and rainwater, requiring less frequent cleaning. It is also sturdy with extra purlins, braces, and support, giving maximum safety and protection against outdoor elements.
2) Permits
Comply with local building codes and regulations to avoid any future issues or penalties. Usually, dwelling units are allowed to be up to 1000 sq. ft. in size, but check in with your local zoning office to confirm. Consider setback rules from your property line and home before choosing an installation site. The permit for a 4 car garage will average cost between $150 to $500.
Note: You will also need a permit to install HAVC, electrical/ plumbing lines, or fences. To convert it into a four car garage house, you will also need a permit [$800 to $1500].
3) Budgeting
Let’s break down the cost of materials and construction. Installing a steel building costs between $25 and $45 per sq. ft. However, there are multiple factors that affect the price of a metal garage, namely, steel market price, size, customization, and location. About 40% of the total budget will go towards buying raw materials, 15% in site preparation & foundation, 15% to construction & permit, and the remaining 20% includes insulation, accessories, and basic interior finishing.
3.1) How Much Does It Cost To Build A 4 Car Garage?
It all boiled down to the specifications. For example, a prefab side entry metal garage with dimensions 26 ft. wide x 40 ft. long and a height of 9 ft. costs $15k. In case you are wondering how much it costs to build a two story four car garage, a 44 ft. wide, 40 ft. deep, and 18 ft. tall metal building start at $41k.
4) Hiring A Contractor

6) Features To Consider For Four-Car Garage

A 4 car garage size is large, which makes it susceptible to condensation. Insulators with correct R-value [varies with climatic zone] can help reduce heat transfers and moisture buildup.

We provide a double bubble and woven R17 insulator that has superior thermal protection & durability.

For example, double bubble costs around $.35 per sq. ft., fiberglass [popular] costs about $0.44 per sq. ft., mineral wool costs about $0.75 per sq. ft., woven R17 costs around $1.50 per sq. ft., and cellulose costs about $0.15 per sq. ft.

With ventilation, you can remove moist, warm air and bring in a fresh breeze. But, how to ventilate a four car garage? Simply open windows and doors for some air to enter. There are two types of ventilation systems for 4-car garages, and can be used in hybrid form. You can invest in floor/ ceiling fans, exhaust fans, garage vent fans, etc., for a more controlled [mechanical] vent system.
6.3) Lighting

An LED recessed ceiling light, LED high bay light, flush-mounted LED ceiling lights, etc., are some of the best types of lighting for a garage.
6.4) Flooring And Security Options

For security, you can integrate IoT devices like motion sensor cameras & lights, surveillance system & alarm, reinforced doors, smart locks & auto garage openers.
