Understanding Building Permits in Toronto: What You Need to Know
If you're planning a renovation or custom home build in Toronto, you'll need a building permit — and navigating the City's process can be one of the most frustrating parts of any project.
What Requires a Building Permit?
In Toronto, a permit is required for:
- New home construction
- Home additions (any size)
- Structural alterations (removing walls, adding openings)
- Basement apartments
- Decks over 600mm high
- Most electrical work
- HVAC installations
Cosmetic work generally does not require a permit.
How Long Does Approval Take?
For complete, compliant applications, the City of Toronto currently processes permits in 8–14 weeks. If your project requires a minor variance, add 3–4 months.
Key factors that cause delays:
- Incomplete drawings at submission
- Missing engineering sign-offs
- Zoning issues requiring variance applications
Tips to Avoid Delays
- Submit complete drawings the first time. Revisions restart the clock.
- Confirm zoning compliance before finalizing design.
- Order long-lead materials the moment permits are approved.
- Never start construction without a permit in hand.
