85% of homeowners look for a garage when shopping for a new home.
This space could be used for anything, but it’s a highly desirable feature, even if it’s a detached garage.
But what if you’re a homeowner, and you are garage-less? Adding a garage to your home will likely boost your chances of selling your home fast.
Let’s look at a detached garage cost if you plan to build a garage.
Detached Garage Cost: The Basics
Adding a garage is a large expense to a home, but it may be a smart move.
A typical homeowner, when building a garage on their property, could raise the value of their property by $15,000 to $30,000, depending on the type of garage.
So, even though it seems like a hefty expense at first, you’ll likely have a great return on investment.
Overall, the average cost of a detached garage is going to fluctuate depending on many things, such as labor, materials, permits, and regional contractor rates.
Key Cost Factors
1. Size
The size of your garage is going to be a key factor in the cost of your garage. If you need a larger space, the cost will increase, and vice versa.
However, you do have to take into consideration your needs and space, and if it will be worth it for you.
2. Additions
Besides space, anything extra you want, like insulation, lighting, windows, special flooring, garage door opener, living space, and so forth, will cause the bill to go up.
When the garage is detached, you will have to run electricity to it and water if you choose.
You can choose how many outlets and lights you want to have, so keep in mind that the fewer you have, the less expensive it is.
3. Location
Do you know where you want to put your garage? Do you already have a foundation laid or broken ground? If the answer is no, add this to the list!
The location of your garage will also determine the cost. You might need to factor in things like tree removal, laying concrete, leveling, and so forth.
