Laneway houses—also known as garden suites or detached secondary dwellings—are becoming increasingly common across Toronto and other Ontario cities as homeowners look for ways to add additional living space or generate rental income. These homes are typically built behind the main residence on the same lot and can be used for long-term tenants, family members, or guest accommodations. Because a laneway house is a fully livable dwelling with its own kitchen, plumbing, and utilities, insuring it properly requires careful consideration beyond standard detached structure coverage.

Laneway and Gardensuite Home Insurance FAQ
-
Do laneway houses require separate insurance in Ontario?
In many cases, the laneway house can be insured on the same policy as the main dwelling. This is often the preferred approach when the property is owner-occupied. If both the main home and laneway house are rented out, they may instead be insured together under a landlord or commercial property policy or added as rental properties to the homeowners’ policy.
-
Is a garden suite covered under a homeowners insurance policy?
Garden suites are not automatically covered under a standard homeowners policy. While many policies include coverage for detached structures, that coverage is typically intended for smaller buildings such as sheds or garages. Many insurers require the garden suite to be specifically declared and underwritten before coverage can be provided.
-
Can a laneway house be rented out and insured as a rental property?
Yes, a laneway house can usually be insured as a rental property. In many situations it is best to insure both the main dwelling and the laneway house with the same insurance company and policy, especially because liability exposures can involve the entire property.
-
What type of insurance is required for a laneway house in Ontario?
The insurance structure depends on how the property is used. If the owner lives in the main home, the laneway house is often added as an additional structure or location on the homeowners policy. When both dwellings are rented, the property may instead require a landlord or commercial insurance policy.
-
Do you need builders risk insurance when constructing a laneway house?
In many cases the existing homeowners policy must be updated or endorsed to reflect that construction is taking place. Some projects may also require a builders risk policy to protect the structure while it is being built. It is important to speak with an insurance broker before construction begins.
-
Is a laneway house considered a detached structure for insurance purposes?
In many situations insurers treat a laneway house as a separate insured location, rather than a typical detached structure. Some insurers may allow it to be insured under detached structure coverage, but only if the insurance limit is sufficient to rebuild the laneway house and if their underwriting rules allow it.
-
Does adding a garden suite increase home insurance premiums?
Yes, adding a garden suite or laneway house will typically increase the cost of home insurance because there is an additional dwelling that must be insured.
-
How much does laneway house insurance cost in Ontario?
Insurance costs vary depending on factors such as size, construction quality, occupancy, and whether the unit is rented. In practice, premiums can range from around $900 per year for smaller units to $4,000 or more for larger or rental properties. There are many factors which influence a quote which is why every situation is unique.
-
Can a laneway house be insured under the same policy as the main home?
Yes. In many cases the laneway house can be insured under the same policy as the main dwelling, which simplifies coverage and helps ensure that liability protection applies to the entire property.
-
How do insurance companies treat accessory dwelling units (ADUs) in Ontario?
Insurance companies treat ADUs differently. Some insurers are comfortable covering laneway houses, garden suites, or guest houses, while others may decline properties with multiple dwellings. Because underwriting rules vary widely, it is important to speak with an experienced insurance broker.
