We live in times when finding a parking space close to home has become a matter of luck. Therefore, car owners who live in a house with a courtyard can consider themselves privileged by fate. If you still have the chance to park your car in a yard, it would be a shame not to take advantage and build a suitable space where it will be sheltered from the weather, the sun’s rays, or the “greeting messages” of pigeons and other flying birds.

We are talking about a garage, which should be included, if possible, in the construction project of a house from the start. The garage can also be built after you have completed the house, and in this article, we will show you the costs involved in this project.

How Much Does It Cost To Build A Detached Garage?

There are several factors that will affect the cost of building a detached garage such as the place where you are living, the size of the garage, whether you already have a garage that has to be demolished and removed, and what features would you like to include.

When building a new home or upgrading to a new garage, these days, only a few people opt for a single-car garage. Instead, they choose a garage large enough to accommodate two to four cars, plus other things.

Another important cost factor is the grading of the land when the site where the garage will be built is not landscaped and graded properly. Also, for ideal drainage, you can install a graded slab and concrete footings.

You should expect to spend around $60,000 to build a two-car detached garage, while the costs for a four-car detached garage would increase to $89,000. But you can find out more about the costs involved with installing a new detached garage of different sizes by taking a look at the tables below.

Item Cost per square foot
Four-car garage $129 $116,864
Two-car garage $90 $172,800

What about the prices of materials?

Item Cost per Unit Cost
Electrical wiring Hourly or flat fee Varies
Doors $300 to $1,200 each $300-$2,400
Windows $350-$800 per window $350-$1,600
Asphalt roofing shingles $100-$120 per square foot $900-$2,000
Roof trusses and support beams Prices vary Varies
Concrete materials $90 per cubic yard $2,400

What are the extra costs?

You will have to buy at least one main door and one overhead garage door for your new building. The overall costs for this project will significantly increase if you are going to purchase high-end materials and more than two doors.

Plan on spending another $320 to $380, if you would like to install automatic door openers.

The stages of building a detached garage

Before starting the actual construction of the garage, it is good to draw up a plan. It should contain information about the dimensions of the garage, how many doors/windows you want it to have, what materials you prefer, who will do the work, etc. Below are the steps required to build a detached garage:

Choosing the location of the future garage – will it be attached to the house or not, will it have room for two cars, etc.;

Obtaining the necessary approvals and documentation, to be able to start the works.

The discussion with the contracting company and the signing of the contract (if you delegate the construction of the garage).

Pouring the screed – the screed is a mixture of sand and cement. For a homogeneous mixture, it is advisable to use a concrete mixer.

Casting cement – this should also contain thick wires, which provide stability to the construction. The cement foundation should be at least 4 inches thick and don’t forget the spaces for water drainage.

Building the walls – regardless of the material chosen, now is the time to build or mount the walls. Leave the tiles as close as possible to each other to prevent dust or snow from entering.

Covering the garage – you can cover it with metal, polycarbonate plates, or other materials.

Painting – choose a paint adapted to the materials used. For example, if you are using wood, you will need a varnish.

Choosing doors and accessories – opt for garage doors adapted to your needs and accessories to help you quickly find the things you need.

Functional areas in the garage – in addition to the area intended for the car, you can set up a workspace, shelves, or cupboards with tools.
