How Much Does A Steel Garage Cost? (Read This First!)

How Much Does A Steel Garage Cost

You may be thinking about creating a new structure on your property. Metal buildings are a valuable bang for your buck, and the cost of a steel garage can be fairly priced if you know what to look for. The ranges are affordable, and can come with many perks; check this out.

Considering the two types of metal garage types, a Quonset hut ranges from $7 to $15 dollars per square inch, and a rigid frame will average out to be $10 to $25 dollar per square foot.

More of a “Do-It-Yourself” kind of person? Luckily, there are metal kits that allow you to fix up your garage the way you want it, or have a manufacturer come out and build it with you. These metal garage kits range within pretty fair prices:

  • 25 x 39 x 13: $5,000 – $6,000
  • 34 x 36: $9,000 – $10,000
  • 35 x 75: $19,000 – 20,000
  • 50 x 100: $28,000 – 30,000

The ranges of prices for a steel garage is primarily based on whether it’s one, two, or three-car garage. There are several factors to include when calculating the cost of various types of garage. Let’s take a more in-depth look to make sure that the price is right.

1- Car Steel Garage Cost

Did you know about 18% of homeowners own a one-car garage? Which means that 18% of garages within North America paid within the same range. A  standard 12’ x  24’, or 288 square feet steel garage will run around $14,100, and a 14’ x 28’ at 392 feet garage is about $19,200.

There are several factors to include when calculating the cost of this type of garage. Whether it’s attached to a building or not, and the size and type of the car that it will housed in it, are taken into consideration to build the perfect garage to fit your needs.

Attached Garage

When the factors are all combined, the cost of a one-car attached garage is between $7,500 and $12,500, at an average cost of $10,800. Of course renovations and customizations will increase the price, as well as the type of carport that you have connected to it.

You should know that a single-car attached garage is way more affordable than detached, because it uses an existing wall; thus, less materials are needed to build it. In addition, they are known to be quite strong against the natural elements because it has the support of the entire house.

An advantage of an attached garage door is that it can use the electrical, HVAC, and plumbing system of the house. Also, when the garage is attached, the price of it is usually fixed into the total price of the house, which takes an addition cost off of the bill.

Detached Garage

The price of a one-car detached garage is averaged at $13,200. A steel detached garage is usually set at a higher price because it has to be assembled from the ground up, you may need additional help that will process a fee, and property taxes may increase if the garage can obtain a legal permit for a separate property entity.

Additional factors like living space above the car will increase the total price because it will need extra plumbing and electricity setup, which adds more expenses to the list. And don’t forget the door! That will add a few more thousands to the bill as well.

But here’s some good news! Detached garages can increase your homes’ property value. That’s a major plus. It goes to show that with the cost and value of a detached garage, it results as a positive investment.

Vehicle Type

A standard garage is set up to hold a sedan, similar to that of a BMW. There are more popular standards when considering the dimensions of a garage; the most common nowadays is the 1.5 garage; which is a metal building that can fit both a large and a standard-size vehicle.

A standard one-car garage is between 12 and 16 feet, while the average Hyundai is about 14 ½ feet. This seems suitable…until you hit your car door on the wall every time you open it.

So imagine your sport-driven SUV sitting next to your shiny Coupe. That’s a wonderful image. This option creates a spacious garage that will allow you to walk around in, and your car door to comfortably open, without fear of hitting the wall.

The average cost for a garage renovation is about $6,500 dollars. Most people end up renovating their garage because the dimensions are not spacious enough for their vehicle, so expanding with a 1.5 steel garage will only benefit you.

2-Car Steel Garage

Fun fact! The average house in North America has a two-door garage! Typical cost of a 2-door steel garage is ranged between 400 and 576 square feet, at a price of about $49 dollars per square foot. Most manufacturers advertise their double-wide metal garages around 18’ to 24’, with the length being customizable for your specific car.

Attached Garage

Ready to build your 2-door steel garage and attach it to your house? That will be $19,300 please! Which is the average cost if you want it attached. The starting cost is approximately $14, 100, and increases based on the amenities that you desire for it.

Detached Garage

The starting cost is near $14, 250, and ranges between $19, 600 and $28, 200, based on the materials that are needed to perfect the job. For this option, building time is the prime factor, simply because of the size of it. Also take into consideration the type of land that it will be built on.

Vehicle Type

The type of automobiles that are made for a two-door garage can be anything from two standard sized sedans -like a Chysler and Mercedes, to two heavy duty trucks, like a Buick and an Expedition! It all depends on the dimensions of the garage, and the other amenities that you have in it.

The most popular 2-door steel garage dimensions is 24’ x 24’, which can fit two standard vehicles, like a Toyota or Honda. However, the garage can be built up to 40’ long in the 24’ x 50’ or 28’ x 40’ dimensions, which can house two larger cars, like a full-size sedan, or a small-to-standard SUV, like a Ford Explorer.

3- Door Steel Garage

Of course, this is your most expensive bet. Three- car garages charge about $28,200 and $42, 700 for onsite building, and prefabricated installation. Per square foot ranges between $576 and $864.  Let’s see how the numbers add up when it’s attached versus detached.

Most three-car garages are detached from the house. A  standard 40’ x 20’ detached steel garage usually starts around $12,050. On the high end, it will ascend up to $42,000 for a 60’ x 52’ building; for perspective, that’s about twenty feet tall.

The 60’ x 52’ option is a better choice if you prefer to move around, do home projects, or store your personal goods in.

Vehicle Type

A standard passenger car is about 14’ long; so you can fit three Honda Civics perfectly within a 24’x24’ garage. But what if that’s not enough space for you to store the refrigerator and the kids bikes in it?

Hike up the dimensions to 36’x24’, and you’ll be able to fit three full-size sedans with no problem! Heck, throw a full-size pick up in there too. They measure from 18 feet to 22 feet long, which is what the three-car garage is meant to do.

Benefits of Steel Garages

Of course a steel garage is stronger than your typical wooden garages due to the material that it’s made of. What I have for you are more significant benefits that will make a steel garage all the more attractive for your property and car.

Longer Life Period

Because a steel garage can withstand the elements better than a wooden garage, the warranty is usually for 25 years! It’s also better at rejecting nature’s mold, mildew, and pests.


It’s way easier to clean! Wooden garages are susceptible to the elements, and could result in rot and mold, which is damaging to any garage. With a pressure washer, and a store-bought or homemade cleaning solution, your efforts will have that metal garage gleaming in no time.

Aids in Saving the Earth

teel is one of the most recycled metals. Therefore, if you have a steel garage, there’s a likely chance that it was created from reused material! Continuously using this option will reduce the cutting down of trees, thus, helping the world to be a greener place.


Steel building manufacturing is created on the premise of using prefabricated material that can easily be assembled. If you purchase a prefabricated garage you’ll save about 60% in labor cost!

If you can follow the instructions on the Do-It Yourself (DIY) steel garage kit, you’ll save even more; possibly another 10%! And because they are usually insulated, you’ll have a much lower heating and cooling bill, compared to traditional wooden garages.

Erecting your own metal building via a Do-It-Yourself project is a big money saver when compared to hiring a contractor. With insulation installation and trim, you could save about $3.50 to $4.00 per square foot!

  • A variety of designs: Although steel garages look like big shiny boxes with windows, there is more than one way to design it. Modern manufacturing finally has the capacity for metal garages to be finished in various colors, textures, and styles, so you’ll get the aesthetics, along with functionality!
  • Durability: Keep in mind that the cars you’ll be housing in the garage are also made of steel. It’s ability to withstand the elements makes it one of the strongest man-made metals to date. Take full advantage of it.

Due to its manufactured design, steel is said to be guaranteed not to wrap, rot, or crack! Want more? Steel is also guaranteed to be fire, pest, and mold-resistance.

  • It’s an investment: Did you know that you could increase your property value by 10-13% by having a steel garage? Compared to home single-family homes that have no garage, the sturdy addition makes your home more valuable!

Do Steel Buildings Need A Foundation?

Yes. A solid foundation is necessary for any metal building.

There are several different types of foundations for steel buildings, and their major purpose is for stabilization. If you are thinking about which foundations to use for your steel structure, consider one of these:

Floating Foundation

A concrete slab with continuous grade beams, a floating foundation (or commonly known as “slab”) is used mostly for commercial or industrial buildings. The mix is poured into the designated section, which reinforces the bottom of the slab, and holds the weight of the pillars. Once it’s completed, the slab becomes the floor.

Important notice! With a floating foundation, the electrical component and sewer pipes must be laid within the slab during its construction.

It doesn’t require any digging or footings, which makes it much faster, easier, and more economically efficient than other foundations. It works well in coastal areas that have softer soil, and prevents unevenness.

Portable Foundation

Portable foundations are absolutely great because it removes the potential risk of the building losing its height due to sinking, or a weak foundation.

It’s extremely useful for transporting building! How amazing is that! The foundation is made by connecting a simple industrial plate to a concrete border, using anchor bolts. This creates variability when designing your landscape. A powerful factor to consider.

Depending on the size of the garage, if you have a heavy-duty truck and some connectors, you could simply pick up the foundation and move it to your next destination.

Portable foundations can be moved via two fashions: disassemble and reassemble, or the direct option of simply picking it up and hauling it to its new land. Larger quonset garage buildings are said to be more efficient to disassemble and reassemble versus moving it as a whole.

Perimeter Wall

This foundation is all about stability and support. The mix is poured around the exterior – or perimeter – of the metal structure. Because it’s on the outside, it supports the inner steel framing walls.

An interesting fact about this particular foundation is that it creates an underfloor space. I also found out that a perimeter wall may also be used when designing with piers or concrete slabs.


The curb foundation is swiveled within the perimeter of the structure. It includes the footings that bear the weight of the structure, and stands several inches above ground, like a street curb, while providing a strong base for the outside walls to be built upon.

Did you know that certain areas of the curb can be dug out so that you can create a crawl space underneath it? It won’t be habitable, but it could aide in providing more room to your property. In addition, a ribbon foundation is created within it by pouring more material into the perimeter curb to support the weight bearing walls.

Pier, Footing, And Grade Beams

The purpose of piers and footings is to manage the vertical weight of the steel building. Piers are drilled deep into the ground (works better with dry soil,) and the deeper the piers go, the more it will help stop any wind uplift that could happen to the building.

Piers can also be tied together beneath the soil to eradicate any underground shifts that may occur. Beams work in a different way: they resist against slight pressures to the soil, which keeps the horizontal columns in place.

This foundation is does wonders for agricultural steel building, open pavilions, and riding arenas. Each pier hold the weight of a column, that rest on rectangular footings with a grade-beam wall.

Although this is an expensive option, it’s one of the more reliable and versatile foundations.
