A laneway house, also known as a coach house or laneway suite, is a small secondary dwelling located on a residential property, typically in the backyard or on the laneway. These small homes are becoming increasingly popular in cities across Canada, including Toronto, for their versatility, income-generating potential, and added value to the property. Some estimate that 48,000+ Toronto homes qualify to build a laneway house. 

Below, we explore the topic in detail to help homeowners decide if they should add one or not.

What is a Laneway House?

A laneway house is a small residential dwelling built in the backyard of an existing property – it can be a detached, semi-detached or freehold townhouse. They have their own entrance, kitchen, bathroom, and living area, making them fully self-contained living spaces. They can be used as a rental property, a home for a family member, a guest house, or a workspace. 

Benefits of Laneway Houses

There are so many reasons to add a laneway suite:

  1. Extra Income A laneway house can provide an additional source of income if you choose to rent it out. We regularly have tenants approach us who are looking specifically for a laneway house. 
  2. Accommodate Family Members It’s a great option if you need to accommodate adult kids or aging parents – they’re close by, but still maintain their independence. 
  3. Add Value to Your Property Laneway suites are one of the best ROI renovation opportunities, and you’ll reap the rewards when it’s time to sell. 
  4. Affordable Housing Shortage It’s no secret that Toronto has a housing shortage, and this a great way to add housing in a dense urban area. 

Things to Consider Before Adding a Laneway House

Zoning and Bylaws

Before adding a laneway suite to your property, you need to check the zoning and bylaws in your area. The City of Toronto has embraced laneway housing, subject to rules and requirements that need to be followed. You can find the latest City of Toronto Laneway bylaws here

Design and Size

Laneway houses come in different shapes and sizes, and it’s important to consider the design that will work best for your property. You’ll also need to ensure that it meets the maximum allowable square footage in your area.

Costs and Income Potential

Building a laneway house is expensive, but the rental income and long-term value it adds to your home may very well make it worthwhile.

  • How much does it cost to build one in Toronto? The cost of a laneway house depends on the size, design and finishings; typical costs start at around $300,000 in Toronto.
  • How much income can I expect from a laneway house in Toronto? Depending on the size, style and location, you can expect to rent it for $2,000-$4,000 or more. Rents for laneway houses are comparable to rents for similar apartments or houses. 
  • How much value does it add to my house? Laneway houses are very much in demand in Toronto and, when listed for sale, attract a lot of attention. How much value it can add to your home depends on the size, finishes and income potential. 
  • How can I finance the construction? There are several financing options available for homeowners who want to build a laneway house, including a second mortgage, a home equity line of credit, or a personal loan. Talk to your banker and accountant to see which option makes the most sense for you. 
  • Are there any tax implications? Building a laneway suite can have tax implications for homeowners. If you rent it out, you’ll be able to write off any interest you pay to build it, though the rent you receive will be taxable income. When it comes time to sell your home, you’ll likely be paying capital gains tax on the portion of your home that’s an income-generating laneway house. Talk to your accountant. 
  • What are the insurance requirements? Just like your primary home, you’ll need to get insurance on a laneway house, including liability insurance. 

Access and Parking

Access to the laneway house can be a challenge, particularly if you’re using it as a rental property. It’s important to consider parking options for tenants and guests.


Laneway houses require services such as water, sewer, and electricity. You’ll need to ensure that your property has the capacity to support the additional dwelling.


Adding a laneway house can impact the privacy of your backyard and your neighbours. You’ll need to consider how it will be situated on your property to minimize the impact on privacy.


Finding a reliable contractor is essential when building a laneway suite. It’s important to do your research, read online reviews, get references, and ensure that the contractor has experience. You don’t want your contractor learning the ins and outs of laneway houses while building yours. Make sure that your contractor is working with licensed electricians and plumbers. 


In Toronto, you’ll need to get a building permit before you can build a laneway house, and there’ll be a whole lot of inspections, including electrical and plumbing. Building a laneway house without a permit isn’t just dangerous – you may be forced to tear it down. You can read more about permits here.
