Building a garage: the steps to follow

Are you considering the addition of a garage to your home? Do you want it detached or attached to the house? Or could you be planning to convert your carport into a garage, or possibly building a room over a detached garage?

Now that's a great idea! Adding a garage will not only prove to be very practical, but it will also increase the resale value of your property.

However, such an important project requires some serious planning. In order to avoid making mistakes that could become disastrous while at the same time staying within your budget, take the time to consult with an expert in the field of garage plans.

Planning stages

The main steps involved in planning the construction of an attached garage are the following:

  1. determine your needs
  2. 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
  3. design the plans for the garage with the help of a professional who will make sure your needs and any local regulations are respected
  4. obtain the building permit
  5. plan financing
