Here is a mapping, from the University of Toronto's School of Cities, showing the number of "closed" building permits issued in Toronto between 2013 and 2023 for both rear-yard suites (laneway houses and garden suites) and secondary suites (like basement apartments).

A "closed" building permit probably means that construction is complete. However, it is not uncommon for a permit to inadvertently remain open. This happened to me with Mackay Laneway House. The permit was supposed to be closed, but it wasn't.
So here's the same mapping with open (i.e. active) permits also turned on:

Three things immediately stand out:
Secondary suites seem to be somewhat evenly distributed across the city.
Rear-yard suites are heavily concentrated in the older areas of the city, flanking the downtown core.
North Toronto is wealthy and isn't having either of these housing typologies.
Looking at these mappings, it probably seems like a decent amount of new housing. But that's not really the case:
From 2013 to 2023, Toronto issued 2,209 building permits for secondary suites (1,525 have been closed and 684 remain open as of December 31, 2023).
And from 2020 to 2023, Toronto issued 898 building permits for rear-yard suites (192 have been closed and 706 remain open, which does suggest some increased adoption). Rear-yard suites only became permissible in 2018, which is why the date range is shorter.
To be fair, I would imagine that many secondary suites get built without a building permit. So I think the above number is probably underestimating actual supply. But even still, it doesn't change the conclusion: A lot more needs to be done to increase the supply of new housing in Toronto.

Laneway housing is back in the news here in Toronto. Last week the University of Toronto reported that they would like to build 50 laneway houses within the Huron-Sussex neighborhood and that they are aiming to start a 2 house pilot project some time in 2018.
Here is a drawing from their Planning Study:

What you see is mid-rise infill (orange) along the main streets and low-rise infill (purple) along the secondary streets and laneways. There’s also a “living lane” that runs north-south through the neighborhood.
I know we’ve talked a lot about laneway housing and neighborhood intensification on this blog, but I hadn’t seen the above plan before. And I wonder if we aren’t going to look back at this neighborhood plan as a prototype for low-rise intensification.
I just got home from the Citywide Laneway Suites Consultation meeting that was held this evening at the Evergreen Brick Works here in Toronto. (I guess I do find time to go to public meetings.)
For those of you who are interested in laneway housing, or an equivalent housing typology, here are a couple of takeaways from the event.
There’s political support. Councillor McMahon and Councillor Bailao were there voicing their support for laneway suites. Both see it as an opportunity to diversify the housing stock and increase the supply of affordable ground-related housing in the city.
Laneway suites (in the context of this current groundswell) are being thought of as secondary suites – exactly like basement suites. This is a smart approach that gets around a number of the hurdles that laneway houses currently face in the city.
Because of this, the idea is that both the main house and the laneway house will remain under the same ownership. No property severances. No selling off the back lot.
Other than this, nothing was really put forward in the way of guidelines. The whole point of these public meetings is to solicit community feedback and then roll that into a set of laneway suite design guidelines that will allow these homes to be built “as of right.”
Obviously there are a number of questions around building height; minimum lot size; window orientation (laneway and/or backyard?); maximum number of secondary suites on a property (would both a basement and a laneway suite be allowed?); and so on.
The next step is a report that will get submitted to the city in the new year. So if you haven’t already, please complete this Lanescape survey. We’ll see where all of this goes, but right now you can certainly feel the momentum.
I also don’t think this is a Toronto-specific topic. Many other cities have adopted similar policies and I am certain that many more will do the same in the future.
