Prefabricated Garage Price List by Material

Prefabricated garages range in price by material. Steel is the most affordable, while vinyl takes the middle spot, and wood is the most costly.

MaterialPrice RangeAverage Price
Steel$2,000 – $50,000$26,000
Vinyl$4,500 – $95,000$49,750

Steel Garage Price

Steel prefabricated garages cost $2,000 to $50,000. They’re the most DIY-friendly and cost-effective variety. They’re often pre-made in modules or kits, making setup and installation easy. Always check on warranties for rust and damage.

Vinyl Modular Garages

Vinyl prefabricated modular garages cost$4,500 to $95,000. You’ll find these both as wood and steel framed garages with wood paneling covered with vinyl siding and trim. They often have metal or traditionally shingled roofs.

Timber-Framed Wood Garages

Wood garages cost $15,000 to $150,000. Although vinyl-sided garages often have wood frames, this price range only reflects timber-finished garages.

Prefab Garage Prices by Size

Naturally, the bigger the garage, the more you'll pay. A single-car garage costs significantly less than a large, four-car one, for example. Additionally, a carport costs less than a full garage, as it's a simpler build and consumes less material. The lower end of the price ranges in the table below reflects the minimum dimensions for the number of vehicles. 

However, if you also need storage space or workspace, and you don't want to shell out for the cost to build a shed as well as a garage, you'll need to size up, so your costs will rise toward the upper end of the price range.

Single-Car$2,000 – $30,00012’ x 20’
Double-Wide$4,000 – $50,00020’ x 20’
Triple-Wide$10,000 – $70,00030’ x 20’
4-Car Garage$20,000 – $95,00040’ x 20’
Carport$2,000 – $20,00012’ x 20’
2-Story$20,000 – $130,000+12’ x 20’

Single-Car Garage

For a single car garage, expect to pay between $2,000 and $30,000 for a minimum size of 20-by-20 square feet. If you have a particularly wide or long vehicle, remember to size up to accommodate it. Similarly, add between four and 10 feet to build in storage or a workspace.

Double-Wide Garage

A double-wide garage costs between $4,000 and $50,000. It has a minimum size of 20-by-20 feet and can accommodate two cars side by side. Some people choose a double-wide garage to house their car, family bicycles, and storage space for hobbies. If the prefab unit you purchase comes with twin doors, but you'd rather switch them for a single double-wide door, the cost of a new garage door is $800 to $4,000.

Triple-Wide Garage

Priced at $10,000 to $70,000, a triple-wide garage can house two or three cars and a modest workshop. Triple-car garages have a minimum size of 30-by-20 feet.

Four-Car Garage

A four-car garage costs $20,000 to $95,000 and has room for up to four cars. You could also accommodate two cars, bicycles for the whole family, and a substantial workshop and storage area in a garage of this size.

Modular Garage Prices by Type

The cost to build a garage varies significantly, based on the type of garage as well as the size. For example, it costs substantially more to build a garage with an apartment above than to build a simple lean-to garage.

Type of Prefab GaragePrice RangeAverage Price
Prefab Garage With Apartment$20,000 – $150,000$85,000
Portable or Pop-Up Garage$130 – $5,000$2,600
Prefab Lean-To Garage$6,000 – $30,000$18,000

Prefab Garage With Apartment Price

A two-story garage costs $20,000 to $150,000, not including delivery or installation. Finishing the second story into an apartment costs another $30,000 to $150,000.

Portable or Pop-Up Garage Price

Portable and pop-up garages cost $130 to $5,000. They’re generally PVC or metal framed with a soft cover, such as vinyl. They come in sizes ranging from a single-car to double-wide or deep. They have limited weight-bearing capacity and don’t always hold up well to strong winds.

Prefab Lean-to Garage

Priced at $6,000 to $30,000, prefab lean-to garages attach to the side of your property. While they only require three new walls, they do require some minor modifications to the structure of your house, hence the slightly higher price tag for a single-wide lean-to garage compared to the cost of a detached garage.

Garage Kits Price

​​Garage kits cost anywhere from $2,000 to $30,000. They include all the pieces required to build the unit with no waste. They sometimes have portions of the building already built, like roof trusses, but that’s not always true. They include the roof, framing, hardware, panels, and siding. They don’t include the labor, foundation, or utilities.

Prefabricated Garage Installation Cost Factors

Besides the kit, you’ll need to have it delivered and placed or built on a foundation. The entire process requires a foundation pad, delivery, and sometimes utilities installed and hooked up.

Installation ServiceCost RangeAverage Price
Foundation$600 – $5,000 total$2,800
Delivery$4 – $10 per mile$7 per mile
Pilot Car*$1.50 – $2 per mile$1.75 per mile
Permits$50 – $150 total$100
Electrical$1,000 – $2,500$1,750
Plumbing$600 – $1,600 per fixture$1,100

Foundation Pad

A garage slab foundation costs about $4,500. While many kits and units require concrete, some only need gravel. Gravel garage foundations cost $600 to $900.

Delivery Costs

Most companies charge $4 to $6 per mile. For oversized units, you may pay up to$10 per mile. The first few miles are often free—usually no more than 20 to 50. Most often, it’s more economical to find a prefabricated garage source close to home. Some companies deliver their products, while kits often use third-party freight services.


Permits for oversized loads cost anywhere from $50 to $150, depending on your state. However, oversized vehicles often need to hire a highway escort service, cars that lead and follow large loads. Pilot car service rates range from $1.50 to $2 per mile.

Electrical, Plumbing & HVAC

To turn your prefab into a living space, you’ll need to install utilities for bathrooms, kitchens, and heating.

Pre-Built Garages vs. Custom

Building a custom garage costs $27,000 on average but can hit $100,000 or more. The average pre-built garage of the same size and type costs about 25% less. However, kits and prefabricated parts for a semi-custom garage can run up to $150,000

If you need to house something larger than a standard car, such as an RV, you'll need an outsized prefab or custom-built solution. An RV garage costs $36,000 to $140,000

DIY Prefab Garage Installation vs. Hiring a Pro

Some garage kits are made for the DIYer. They come complete with all the parts and instructions needed to assemble at home on your land. On the other hand, pre-built garages can’t be DIYed since they’re already complete before they even reach you. Modular builds and kits strike a middle ground. They’re mostly complete but require some assembly on site.

Unless you have home-building experience, hire a pro. Find a local garage builder or general contractor near you. They can help assemble kits and modular units.

Frequently Asked Questions

What’s a concrete sectional garage, and how much does it cost?

A concrete sectional garage is a garage built on site in panels or sections. It’ll cost as much, if not more, than a traditionally built garage, or at least $20,000. Concrete sectional garages still require the site to be leveled and graded and need a suitable base, usually a poured concrete pad. And they'll still require professional installation.

How long does it take to assemble a prefabricated garage?

It takes up to three days to put a basic prefabricated garage together. However, this doesn't include the time it takes to pour the concrete for the base and let it dry and cure. This can add another 10 days to the installation time. And, if you're using a poured concrete base, it'll be a full 30 days before you can drive a vehicle over it. 

Does a metal garage add value to a home?

A metal garage can add some value to the home if the designs are similar and correctly placed. Always try to match the value and design of your new addition to what you already have. Also, make sure it matches your area and neighborhood. If you have wooden siding or vinyl wood-look siding, you'll likely get resale value if you install a matching wood or wood-look vinyl garage.

How thick should a concrete slab be for a garage?

In general, a concrete slab for a garage foundation should be at least 4 inches thick to support a standard vehicle. If, however, the garage will get a lot of use or house large, heavy vehicles, then the slab should be between six and eight inches. It also needs to cure for 30 days after installation before you drive any vehicles onto it.

Are prefab garages as good as stick-built?

Prefab garages can be as good as stick-built ones. It depends on the quality of the construction, its material, and how much care and maintenance you provide. Prefabs are pretty fast to put together, but they are prone to some moisture problems. Many homeowners and pros consider stick-built garages more attractive than other types, as they're custom-built and easier to match to the rest of the property and the neighborhood, but they require regular maintenance and sealing.
