First Steps: Getting Renovation Permits in Ontario

A practical guide to building permits for home renovation in Ontario — what requires one, how to get it, and what happens without one.

Do I Need a Permit for My Renovation?

The Ontario Building Code requires building permits for most structural, electrical, plumbing, and HVAC work. Understanding what requires a permit — and what doesn't — is the first step in planning any renovation.

Work That Requires a Permit in Ontario

Adding or removing walls (especially load-bearing)
Adding or relocating electrical circuits
New or relocated plumbing rough-in
HVAC modifications or additions

Building a deck over 24 inches from grade
Adding a bathroom
Home additions and structural changes

Work That Typically Does Not Require a Permit

Cabinet replacement without moving plumbing
Low-level decks under 24 inches from grade

How to Apply for a Building Permit in Toronto

Permit applications in Toronto are submitted through the city's online portal with construction drawings and project descriptions. Residential permit applications typically take 10–30 business days for approval. aMaximum Construction manages this process on behalf of clients for all projects that require it.

What Happens If You Skip a Permit?

Unpermitted work discovered during a home sale can derail transactions, require remediation at seller's expense, or reduce sale price. Insurance claims for damage in unpermitted areas may be denied. Municipalities can order unpermitted work removed. The cost of permits is always worth it.
