Factors That Determine the Cost of Building a Garage

A major and primary factor determining the new garage’s estimated costs is its size. For instance, the cost of a single-car garage differs significantly from that of an RV-size garage. Along with this, the foundation and roof of your garage also make up a noteworthy portion of the entire cost. How you want to invest in windows, insulation, and electrical wiring are critical factors to calculate while estimating the overall cost of your new garage. Let’s deep dive into all these important factors to estimate the cost of building a new garage for you.

A. The Size of the Garage:

A new garage costs on an average of $ 50 per square foot, while the cost can range from $35 to $90 per square foot. While the cost can vary based on multiple factors, for now, we will focus on how the cost of a garage differs depending on its size. The cost of a single-car garage ranges from $10,100 to $27,000. On the other hand, the cost of a 2-car garage ranges from $20,200 to $40,300. Let’s take a look at the following table to understand how the cost of a garage differs depending on its size.

Attached Vs. Detached Garage

The cost of an attached garage is usually less than the cost of a detached garage. This is because an attached garage shares the walls of the house and you can easily pull the electrical wiring. However, there are some exceptions where people invest very little in their detached garages. The average cost of an attached garage is $30 per sq. ft, whereas a detached garage costs $65 per sq. ft on average.

B. Insulation:

If you want to use your garage for other purposes rather than just a parking space, then insulation is a must. Insulation will help to lessen the rapid swings in temperature. Therefore, you can use your insulated garage to store temperature-sensitive items or as a workspace.

Depending on the type of insulation, the insulation cost will vary. If you opt for batting insulation, this will cost from $1 to $2 per sq. ft. Blow-in insulation is a little cheaper that ranges from $0.5 to $1.5 per sq. ft. Whereas, the cost of spray-in insulation ranges from $1.5 to $4 per sq. ft.

You can roughly estimate that you have to spend between $20 and $49 per sq. ft for labor costs.

D. Security:

Garage Security

Having security features in your garage is essential to safeguard your car and other items. The cost of a garage security system ranges from $100 to $2,500 depending on the security system.
