Nationally, the average price for building a new garage costs between $4,500 to $80,000 which is obviously a huge range. That's because building a new garage depends on so many things, and they all affect price. Size, materials, extra features and more can all influence the cost estimate your contractor gives you. So let's break it down.
Attached or detached garage which is cheaper?
An attached garage attached to an existing structure, like your house tend to be cheaper and more common. You can choose to have a roof covering only (no walls) or keep the area enclosed. One nice thing about an attached garage is that it provides an entryway into your home, so you can avoid bad weather on a rainy or snowy day. Construction can cost less for an attached garage since the garage can use walls or power that's already there. Even better if you already have a driveway.
Detached garages usually cost more. They're standalone buildings, so there are more construction costs. But they're safer and more secure because they don't provide an entryway into your home. And they're a good option if you don't have an entryway with space for an attached garage. You tend to have more flexibility with detached garages as well they're easier to expand, and you can plan for more storage.
How does garage size affect the cost?
The national average cost per square foot to build a garage is between $30 - $40, but it will depend on the project scope, materials and how expensive your city is. Before you decide on your garage size, check if there are any size restrictions. In some cities, a garage can't go over a certain percentage of the lot's square footage, according to contractor pro Homes. Then think about how many cars you have and if you want extra storage (for bikes or other equipment.)
In general, the bigger the project, the higher the cost bigger' means more contractor labor, more time needed to build, and more material costs. Anything that will take more time will add to the cost. For example, an attached two car garage on flat ground will take contractors less time to build than a detached four car garage on a hill.
What about construction materials?
Surprise surprise different building materials affect the price. This isn't a complete list, but here are a few examples and how they can change your total estimate.
What extra features can affect cost?
So size, timing and materials all affect the price. What else?
Basically, costs can really vary depending on project scope. Here are two examples of costs for different garages built by Mateo Homes in the Kansas City area:
26 x 40 standard garage: $38,000
40 x 80 upscale garage: $80,000
What are the cost benefits of adding a garage?
Garage addition can add to the value of your home and boost your ROI if you sell. According to Magazine's 2015 Cost vs Value Report, the average return on a midrange garage addition is 64.8%. Resale value aside, garage addition is still a big investment of time and money. But a garage can protect your vehicles, which means you may spend less on weather and street damage. And you can use your garage as storage space instead of renting a third party unit. So there are other advantages to consider when weighing the cost.
