There are 5 steps to follow:

  1. Plan how you will finance the work.
  2. Check local regulations concerning the size of garages. There are different laws depending on the size of the house and/or lot. For example, there may be setbacks to respect, or even a maximum height.
  3. Clearly determine your needs.
  4. Design the plans with the help of a professional (architect or architectural technician). They'll know how to respect your requirements and local regulations.
  5. Get the necessary permit(s).

How much does a detached garage cost?

The total cost varies considerably - the estimated price per square foot depends on the size, materials and type of project.

Here's a preliminary list of some of the factors you'll need to take into account that impact the cost:

  • Type of insulation
  • Driveway surface - asphalt versus gravel
  • Exterior finish - brick versus siding in PVC or fiber cement
  • Water/sewer connection
  • Architectural details to coordinate your garage with your home

Insulation has a major impact on the total cost and maintenance of your detached garage If you have a heated garage, proper insulation will keep the heat in. Choosing the right garage door to keep the heat in is just as important.

Are you familiar with R-factor? It's a universal unit that measures the degree of heat resistance that insulation has to heat flow, in this case, in a garage door. The R factor will help you choose the right garage door for your project, based on the degree of insulation you require. Learn more about the R-factor here.
