What is a Building Permit?

If you live in Toronto and have a property that backs onto a laneway, you’ve probably heard of laneway homes, and you might be wondering if building one is worth it.
In 2025, laneway suites have become one of the most popular ways for homeowners to create extra living space or generate rental income. But how much do they really cost, and how do they compare to other options like basement units or full home additions?
Let’s break it down in simple terms.
Building a laneway suite in Toronto now costs between $400,000 and $550,000, depending on the size, layout, and finishes.
Here’s a general breakdown of where the money goes:
Item |
Estimated Cost |
Drawings & Permits |
$25,000 to $40,000 |
Construction |
$350,000 to $450,000 |
Utility Hook-ups and Site Preps |
$15,000 to $30,000 |
Taxes (HST) |
13% Extra |
Most laneway homes range between 600–1,000 square feet and are fully self-contained with a kitchen, bathroom, bedroom, and separate entrance.
While the cost might seem high, many homeowners look at this as a long-term investment — especially if you plan to rent it out.
More Toronto homeowners are choosing laneway suites instead of basement apartments or expensive home additions. Here’s why:
Laneway homes are fully detached, so renters or family members have their own entrance, outdoor space, and no shared walls. It’s ideal for multigenerational living or private rentals.
Unlike basement units, laneway homes offer natural light, ventilation, and above-ground living — making them more attractive to renters.
You still own your full property. You’re just making better use of the space you already have — especially if your backyard connects to a laneway.
Most 1-2 bedroom laneway homes in Toronto can bring in $2,500 to $3,500 per month in rent, helping you offset mortgage payments or even generate profit.
A well-built laneway suite can increase your home’s resale value by hundreds of thousands of dollars. Buyers see it as a flexible space they can use for family, work, or income.

If your property qualifies under the City of Toronto’s laneway housing rules, a laneway home can be a smart and flexible investment. Whether you want to create space for aging parents, generate rental income, or increase your property value, it’s worth exploring.
And in a city where space is limited and housing prices keep climbing, using your backyard to its full potential just makes sense.
