Here are the step to follow:

The main steps involved in planning the construction of a detached garage are the following:

  • Determine your needs.
  • Check municipal regulations (the size of the garage is an integral part of municipal bylaws). Most municipalities have strict rules about the size of garages, sometimes based on the size of the house and/or land. For example, there could be setbacks to respect when choosing the location or even a maximum height to consider when it comes time to design plans.
  • Design the plans for the garage with the help of a professional who will make sure your needs and any local regulations are respected. Work with one of the 22 dealers of Drummond House Plan to add or enlarge a garage.
  • Obtain the necessary permit.
  • Plan the financing of the project.

How nuch does a detached garage cost?

Although the total cost may vary greatly, it costs generally at least $45 per square foot for the material ($60 per square foot if we want an insulated and heated garage) in order to build a detached garage.

For example, for a single garage, 14 feet wide by 20 feet long (4.3 m x 6.1 m), non-insulated, costs can come to between $13,000 and $17,000.

In the case of a double garage 22 ft. by 24 ft. (6.7 m x 7.3 m), the cost is about $24,000, non-insulated. Keep in mind that these prices are approximate and include labor costs.

The price of $45 per square foot ($60 per square foot if insulated) applies for a base model garage, non-insulated, built with standard materials. If you elect to use high quality materials, the price will increase to about $55 per square foot ($70 if insulated) for an non-insulated garage

It is important to note that the above-mentioned amounts only include the construction of the building itself, meaning material and labor, and are only approximate. These amounts can vary plus or minus 15% from city to city.

What’s more, the costs of connecting the garage to the sewers or paving the driveway, for instance, are extra expenses that must be considered when establishing a budget for this type of project.

The exterior finish chosen for the garage also creates a considerable fluctuation in costs. A garage featuring the same type of roof as the house or comparable architectural details will necessarily prove to be more expensive. Similarly, a garage with the façade or even all four walls made of brick will be a lot more costly that a model covered with PVC siding.
