Permits, Contracts & Risk

Nearly every detached garage in Canada needs a permit, and the ones that do not still have to meet the bylaw. What changes from one municipality to the next is the package: which drawings, at what scale, with whose stamp on them, and how long the review takes.

These guides cover the permit package and site plan requirements, when a stamped engineer design becomes mandatory, realistic approval timelines, the inspection milestones an inspector needs to see, and the five things that most often fail an inspection. Provincial differences get their own posts, because Ontario, Alberta, British Columbia, Quebec, the Prairies, Atlantic Canada and the territories each ask for something different. Building without a permit, and selling a house with an unpermitted garage, are covered honestly rather than hopefully.

The reference document is the Canadian garage permit guide. Provincial requirements are summarised on the service area pages for Ontario, Alberta and British Columbia. Zoning and setbacks that decide the application in the first place are in start with your property, contractor vetting is in partner standards, and drawings for your build come with a quote.
