The Cost Of Building A Garage

A garage is a versatile space. Not only can it be used to park and protect your vehicles, but it can also be used as a storage space, a workshop, or even a fresh air space – something that’s increasingly popular since the pandemic began. 

Attached or detached, if you’re thinking of building a new garage or replacing an old one, here’s what you can expect to spend on the project. 

Common Expenses Associated with Building a Garage

There’s a lot to building a garage. It has many features like a house build, so you’ll want to consider everything when figuring your budget. Here are the most common elements of building a garage. 

Concrete Foundation

The beginning of your garage build will start with a concrete foundation. The bigger the garage, the bigger and more expensive the foundation will be. As a reference, the foundation for an average 20’ x 20’ two-car garage will cost between $2,000 and $3,500. 


When building a new garage, most homeowners choose the same siding as their house, so it matches perfectly. You can choose something different to create a dramatic contrast, but keep in mind that the price varies between the different siding options. Vinyl siding is a popular choice for garages and is usually very budget-friendly. 


The framing for your garage will provide its support. Depending on whether the garage is stand-alone or being added to an existing structure, labor costs can be $8 or more per square foot. The framing material you choose also impacts the cost. 


Many people do not insulate their garages, but if you plan to do more than just park cars in there, it’s a good idea. Depending on the type of insulation you choose, you’ll spend anywhere from $1,000 to $3,500 for installation. 


Installing windows is optional but doing so will allow natural light to flood the space. Window installation can cost between $350 and $650 (including labor). 


Another optional feature is drywall. Hanging drywall in your garage can give it a more finished feel. Drywall installation, depending on its complexity, can cost upwards of $1,800. If you know how to do it, you can save yourself a lot of money hanging the drywall yourself. 

Garage Door

Installing a quality garage door not only ups your home’s curb appeal but can also lower your energy bills and add to your home’s value. In fact, you could recoup nearly 95 percent of the cost of a good garage door when you sell your home. 

Adding a garage or rebuilding an old one is a great way to protect your vehicles and belongings. Not only that, it adds value to your home – as much as $5,000 to $25,000! Of course, money should never be the only reason to build an addition to your home. The addition should bring you enjoyment and convenience, too!
