Yes, building permits are required in Kitchener for structural, plumbing, and electrical work. Permit fees typically range from $1,000 to $3,000 depending on the scope of your renovation, especially if you are adding a legal secondary suite.

Adding a 3-piece bathroom to your basement typically costs between $15,000 and $30,000. If your basement does not have existing plumbing rough-ins, breaking the concrete floor to trench new lines can add $3,500 to $7,000 to the project.
