Adding An Attached Garage: What To Consider

An attached garage can be very useful. It offers you a way to protect your vehicles and any yard equipment. It can also raise the resale value of your home by a considerable margin. There are, however, some important things to consider when looking at the option and potential costs of adding an attached garage.

Things to Consider

If you are thinking about building an attached garage, it is important to take a few steps in preparation. Figuring on realistic prices is important but before you begin this process you should first consult with your local government. Most cities will allow the addition of an attached garage but there are some which prohibit such additions. Verify that the job can be done legally before you take any further steps.


The overall dimensions of an attached garage will be the single biggest factor in determining how much the job will cost. The larger the garage, the more it will cost.

House Style

The design of your home can play a big role in the cost. As an example, a two-story house is often cheaper to add an attached garage to because it rarely involves modifying the roof. Many single-story homes require roof modifications in order to properly accommodate the new garage.

Number of Cars

The size of the garage does not necessarily need to be based on the number of cars which will be stored in it but by the number of garage doors it has. The size, type, and number and type of garage doors will play into the price. Using aluminum garage doors is a good way to save some money.

Homes Building Materials and Style

The building materials and style used in the home can play a major role in the cost. While you do not necessarily need to stick with your home's design it often leads to a more unified addition. If your home is brick or block and you wish to continue the exact look into your new garage, the addition will cost you more money.

Additional Potential Costs

There are many other potential additions that can be made to an attached garage. Some of these include windows, electrical, plumbing, insulation, and work areas. When figuring on a cost, get estimates for each option from multiple contractors.

Build a list of all of the materials you will be using. This should include materials such as wood, bricks, plywood, roofing wood, tar paper, shingles, windows, electrical wiring, plumbing, and any other materials you will need for your garage. Once you have this list determine how many of each you will need by taking the total size of the garage and dividing it by the dimensions of each material. In the case of 2x8s for framing, you must remember that these need to be spaced 16 inches off center. Finally, contact local hardware and supply companies and get prices on these different materials and add it up.
