Should You Tear Down Your Bungalow and Rebuild? What to Know

You might tear down and rebuild a bungalow when the house no longer fits your needs but the lot and location are too good to leave. Rebuilding gives you a new home with modern systems on land you already own. It also takes more time, money and approvals than most renovations, so it only makes sense when the numbers and the lot support it.

Why bungalow owners choose to rebuild

Many GTA bungalows sit on generous lots in established neighbourhoods. Over time, the land can become the most valuable part of the property. That’s why you see older bungalows replaced with larger custom homes in parts of Toronto, Mississauga, Oakville and Vaughan.

Common reasons owners rebuild include:

• The home needs a new foundation, roof, wiring and plumbing all at once.
• You want much more living space than an addition can deliver.
• You’d like a modern, energy-efficient home without fighting an old structure.
• You love your street and don’t want to move.
• You want a layout designed for aging in place or multigenerational living.

Rebuild vs renovate: how to decide

A tear down and rebuild is not always the better choice. Sometimes a smart renovation or addition gives you most of what you want for less.

Factor	Tear down and rebuild	Renovate or add on
Design freedom	Full control, within zoning	Limited by the existing structure
Timeline	Longer: design, permits, demolition and build	Usually shorter
Living arrangements	You must move out	Sometimes you can stay
Hidden surprises	Fewer once the old house is gone	More, especially in older homes
Energy efficiency	Built to current code	Depends on the scope of upgrades
Cost	Usually higher overall	Usually lower, but can climb

If more than a few major systems need replacing, get pricing on both paths. Our guide to adding to a bungalow covers second storeys, additions and basement finishing.

Check your zoning first

Your city’s zoning by-law decides what you can build. Before you hire a designer, find out:

1. Maximum height and number of storeys.
2. Required front, side and rear setbacks.
3. Maximum lot coverage and floor area.
4. Rules on garages, driveways and protected trees.
5. Whether you can add units, such as a basement apartment or garden suite.

Ontario’s More Homes Built Faster Act allows up to 3 residential units on most serviced urban residential lots. A rebuild is a good chance to plan for future units from the start.

If your design doesn’t fit the by-law, you may need a minor variance from the Committee of Adjustment. That adds time and isn’t guaranteed. Some neighbourhoods also have heritage or ravine protections that limit what you can do.

The tear down and rebuild process, step by step

1. Feasibility: review zoning, survey and servicing with a designer or architect.
2. Budget: get rough pricing from builders before detailed design.
3. Design: create drawings that meet the by-law and the Ontario Building Code.
4. Approvals: apply for a demolition permit, building permit and any variances.
5. Disconnects: arrange for utilities to be safely disconnected.
6. Demolition: test for hazardous materials like asbestos before work starts.
7. Construction: foundation, framing, roof, systems and finishes, with city inspections at each stage.
8. Occupancy: final inspection, then you move in.

Costs to plan for beyond construction

Construction costs vary widely with size, design and finishes, so get at least three detailed quotes. Then add the costs people often forget:

• Architect or designer and engineering fees.
• Surveys, soil testing and arborist reports.
• Permit and application fees.
• Demolition, hazardous material removal and disposal.
• New water, sewer, gas and hydro connections.
• Rent and moving costs while you’re out of the house.
• A contingency for surprises and price changes.

Talk to your lender early. Construction financing works differently from a regular mortgage, with funds released in stages as work is completed. Ask an accountant whether HST or other tax rules apply to your project.

Will a rebuild pay off?

A new custom home on a great lot can be worth far more than the original bungalow. But there’s no guarantee you’ll get every dollar back if you sell soon after.

The rebuild makes the most sense when you plan to stay for years, the land value is strong and the finished home fits the neighbourhood. Overbuilding for the street can limit your resale value. Knowing what your current home is worth is a useful starting point, so get a free home evaluation before you commit.

Frequently asked questions

Is it cheaper to tear down or renovate a bungalow?

Renovating is usually cheaper, but not always. If the foundation, roof and major systems all need replacing, rebuilding can offer better value for the money.

Do I need a permit to demolish a house in Ontario?

Yes. You need a demolition permit from your municipality, and many cities want a building permit approved before they’ll issue it.

Can I keep a single-storey design when I rebuild?

Yes. Many owners rebuild as a modern bungalow or bungaloft for one-level living. Zoning sets the limits on size and height.

How long does a tear down and rebuild take?

It varies with design, approvals and builder schedules. Plan for a long project and build extra time into your housing plans.

The bottom line

Tearing down your bungalow and rebuilding can give you a new home on land you love. It works best when the old house needs major work, the lot is valuable and you plan to stay.
