Permits in Toronto, plainly
The City of Toronto has its own zoning by-law and building department. Here is what that means for your project.
- Every addition needs a building permit, and so do structural changes, new plumbing and second suites
- Zoning By-law 569-2013 sets how deep, wide and tall you can build. Past those limits, the design needs a minor variance from the Committee of Adjustment first, which adds months
- The City aims to review a complete house application within 10 business days. Overall, permits take 1 to 4 months, longer with a variance
- We prepare the drawings, the engineering and the application, and answer the examiner's comments. See the City's small residential additions guide
