While the real estate market is cooling off, rental prices remain sky high. The low supply and high demand for affordable and suitable housing has created a need in some of the largest cities in Canada. Pair this with rising mortgage rates, and the result is clear: Homeowners in and around Toronto and Montreal are looking into building a legal basement apartment to cushion their income.
However, before we dive into the pros and cons of renting out your basement, we should first look at what constitutes a legal basement apartment in both Ontario and Quebec.
In Ontario, a legal basement apartment is a secondary unit that meets Ontario Building Code requirements. Basically, if your property meets the zoning codes for your area, and your building is over five years old, your second unit needs the following:
On the other side of the Ottawa river, a basement apartment in Quebec has specific regulations based on the apartment’s location. From a provincial standpoint, the most pressing concern is the location and availability of an egress window as a second means to escape. An egress window must be large enough for both a child and adult to climb through and open freely with no anti-intrusion bars.
As you can see, the legalities around basement apartments are pretty specific, and to be a legal second dwelling within the home, the above requirements are the minimum. Further to that, the exact specifications and things you need will depend on where the property is located.
When considering what codes need to be met, you need to remember that you will be dealing with multiple codes at various levels.
If you are in Ontario, your building will need to be up to Ontario Building Code standards. If your building is a little older, it’s best to hire a property inspector or general contractor. They can tell you if you need to complete any updates to the space before considering a basement apartment.
Next, your building will need to meet Fire Code standards to ensure the basement is safe to exit in an emergency. The fire department can complete this inspection, but even if you get their okay, your basement apartment isn’t legal just yet. Finally, you will need to meet the specific by-laws that are in place in your municipality. For example, Toronto, Mississauga, Brampton, Milton, Burlington, and Hamilton have specific by-laws and processes around basement apartments.
Much like Ontario, the rules in Quebec depend on the location of your basement apartment. All buildings in the province, including legal basements, need to meet the Régie du bâtiment du Québec’s standards. Then, most municipalities will have specific rules and regulations around basement apartments. For instance, Montreal has particular rules regarding the configuration, ventilation, lighting, appliances, exits, and other specifics for second dwellings.
Naturally, the costs of a legal basement will vary depending on the area you live in and the condition and layout of the basement in question. However, let’s take an unfinished basement as a benchmark and look at basement renovation costs. We calculate on average for an area of 900 ft2 (i.e. a standard house of 30x30ft or 25x35ft) that a turnkey basement without a bathroom starts at $45,000 in Montreal and $70,000 in Toronto. Keep in mind that this reflects the cost of finishing a basement, not creating a second dwelling.
Considering that a second dwelling requires a full bathroom, kitchen, an independent entrance and other amenities, as well as bringing everything up to applicable building and fire codes, the costs can skyrocket. According to Debora Tricarico, one of our Renovation Advisors, a complete transition from an unfinished basement to a legal basement apartment normally starts at $85,000 + tx based on a model of 900 ft2.
Costs will vary depending on your current set-up, quotes for the work in your area, and the amount of structural work needed to complete the job. Thus, it is always best to talk to a trusted professional contractor or basement specialist who can walk you through the process and work with you to design a space that is not only legal but will also attract top-tier renters.
The process of renting out a legal basement can be overwhelming for first-time landlords. Not to worry, though: we’ve broken it down into easily digestible steps!
