Steel Building Prices: Complete Cost Guide by Size


If you have a big storage problem, steel buildings are the perfect solution. Steel is a high-quality, fire-resistant metal, making it a great option for building durable garages and storage structures. Best of all, prefab steel buildings costs around $10 to $20 per square foot. 

The lowest-priced option, an open-sided carport, has a base price of $6,795 for a 32×20 structure. That said, the price of large metal buildings will vary depending on the size, style, and customizations you choose. 

In this article, we’ll guide you through costs of different building sizes that affect steel building prices. You’ll also learn about what factors impact the overall price, helping you choose the best steel building within your budget.

Additional Cost Considerations

Let’s walk through a few factors and details that affect steel building prices to get a better estimate of how much your custom structure will cost.


The geographic location of your steel building can play a role in the price. Depending on your state or region, your building may require specific roof styles and insulation to suit the weather and wind conditions. 


Functional features like windows and insulation are common additions that contribute to the overall cost. Custom features, such as garage door openers, are more expensive additions. However, these can be a good return on investment, since they add value to your property. 

Construction / Installation

The complexity of construction and labor also factor into steel building prices, which can account for about 20% to 40% of the total cost. This includes erecting, installing, and delivery. If you want to save on labor costs, you can get a metal building kit or take advantage of the free installation and delivery we offer for all of our metal buildings.

Building Permits

Adding any type of building to your property most likely requires a construction permit, which should be factored into the overall cost. Depending on your city’s building codes, you may only need an inspection permit for small garages and sheds.
