Everything you need to know about demolition permits for new construction in Toronto

If you’re tearing down a house in Toronto to build something new, you’re probably wondering about the permit process. The short answer is yes, you’ll need a demolition permit. But here’s the thing most people don’t know – the City usually won’t issue that permit on its own.

How Toronto’s Demolition and Building Permits Work Together

The process isn’t as simple as “demo first, build second”

When you’re planning to demolish an existing house and build a new one, Toronto Building wants to see the complete picture. They need to know what’s replacing the old home before they approve tearing it down.

Here’s how it actually works:

In most cases, you apply for the demolition permit and building permit together
The City reviews your plans for the new construction first
They want to ensure what you’re building is approved before authorizing demolition
This prevents situations where houses get torn down with no approved replacement plans

Think of it as the City’s way of making sure your lot doesn’t sit empty because your new construction plans weren’t viable.

Why Toronto Requires Both Permits Together

Protecting neighborhoods and ensuring proper development

The City has good reasons for this combined permit approach:

Preventing abandoned lots: If demolition permits were issued separately, people could tear down houses and then discover their new building plans don’t meet zoning requirements. The neighborhood ends up with an empty lot for months or years.

Ensuring zoning compliance: By reviewing the new construction plans first, the City confirms your new build meets all current zoning requirements, setback rules, and building codes.

Maintaining housing stock: Toronto wants to ensure that when a house comes down, there’s a solid plan for what goes up in its place.

Streamlining the process: Reviewing both applications together actually speeds things up in the long run, even though it seems like more work upfront.

The Application Process for Demolition and Building Permits

What you need to submit to Toronto Building

When you’re ready to apply for both permits, you’ll need:

For the demolition permit:

Completed demolition permit application
Site plan showing the building to be demolished
Photos of the existing structure
Utility disconnection confirmations (or plans)
Asbestos survey (for older buildings)
Debris management plan

For the building permit:

Architectural drawings of the new construction
Structural engineering plans
Site plan showing new building location and setbacks
Zoning compliance documentation
Energy efficiency calculations
Landscape plans
Grading and drainage plans

Your architect or designer should prepare most of these documents as part of your new construction project.

Timeline Expectations

How long the permit process takes in Toronto

Standard timeline:

Simple residential projects: 6-12 weeks
Complex or larger homes: 12-20 weeks
Heritage or restricted areas: 16-24+ weeks

What affects your timeline:

Completeness of your application
Complexity of the new design
Zoning variances or committee of adjustment needs
Heritage designation of existing property
Neighborhood objections or appeals
Workload at Toronto Building

Start this process early – like, really early. Don’t wait until you want to start construction next month.

Special Considerations for Toronto

City-specific requirements you need to know

Heritage Properties

If your property is designated heritage or in a heritage conservation district, you’ll need additional approvals before any demolition permit is issued. This can add months to your timeline.

Tree Permits

Toronto has strict tree protection bylaws. If there are significant trees on your property, you may need a separate tree removal permit. This should be coordinated with your demolition and building permit applications.

Utility Disconnections

You’ll need to arrange disconnection of:

Hydro (Toronto Hydro)
Gas (Enbridge)
Water (City of Toronto)

Get confirmation of these disconnections as part of your permit application.

Neighboring Properties

The City may require you to notify adjacent property owners about your demolition and construction plans. Be prepared for potential neighbor concerns or objections.

Common Mistakes to Avoid

Don’t make these expensive errors

Starting Demo Before Permits

Never begin demolition before your permits are approved and issued. The City can stop your project, fine you, and make your life very difficult.

Incomplete Applications

Missing documents will delay your approval. Work with professionals who know exactly what Toronto Building requires.

Not Consulting Professionals Early

Your architect, builder, or designer should be involved from the very beginning. They understand the permit process and requirements.

Underestimating Timeline

Don’t plan to start construction in 8 weeks if you haven’t even submitted permits yet. Give yourself realistic timelines.

Next Steps: Getting Your Permits

Your action plan for moving forward

1. Confirm your specific requirements Every property is different. Contact Toronto Building or work with professionals who know your neighborhood’s specific requirements.

2. Engage your design team Get your architect or designer working on plans for your new construction. You can’t apply for permits without complete drawings.

3. Submit both applications together Unless your specific situation is different, plan to submit demolition and building permits simultaneously.

5. Prepare for construction While waiting for permits, line up your contractor, order long-lead materials, and finalize your construction plans.

The Bottom Line
