Recently, I wrote about 4 predictions that I have for Toronto's laneways. And one of them is what I refer to as a "market inversion." What I mean by this is that I think we'll start to see the laneway side of lots become more desirable than their traditional street frontages.
Maybe it won't be a universal thing, but I definitely think we'll stop thinking about laneways as being the "rear" or "backside" of lots and just think of them as quieter and more intimate streets. Because here's the thing, as more and more laneway houses get built, we are, in a lot of cases, removing parking at the same time. And so generally speaking, as time goes on, our laneways are going to become even more pedestrian-oriented by default.
Now here's a built example.
Designed by Williamson Williamson, I think this house, called the Garden Laneway House, is immediately notable for two reasons. One, the overall design is beautiful, especially the exterior brickwork. I mean, wow:


And two, it is a 4-bedroom house for a family of five. In fact, what the family did is turn the front house into a duplex, creating three homes on a lot where previously there was only one. And from the looks of it, it was their preference to live in the laneway house and use the laneway as their front door.
This is exactly the sort of thing that I was getting at with my predictions post.

Montreal has a bylaw that came into effect on April 1, 2021 and that requires developers to contribute to the city's supply of social, affordable, and family housing. (All three of these have their own definition.)
Developers can meet this requirement in a number of different ways:
They can build the social, affordable, and/or family housing
They can contribute land or a building
Or they can pay cash-in-lieu
Usually, I think of inclusionary zoning as being the first of these three bullet points: a hard requirement to build a certain amount of non-market housing. That is not an absolute requirement here, and so I see this policy as being IZ lite.
Since the bylaw came into force, there have been approximately 150 new projects by private developers in Montreal, according to this CBC article. That has resulted in about 7,100 new market-rate homes. At the same time, it has resulted in exactly zero non-market homes.
From what I can tell from the article, every single developer has opted for option three: pay the cash-in-lieu instead of actually building the housing. Supposedly this has produced about $24.5 million in new fees, which sounds like a lot. But if you divide it by 7,100 homes, it isn't all that much: just under $3,500 for each new home.
So what is clear is that this is the least expensive option. That's why everybody is choosing it. If the fee was significantly higher and it was cheaper to just build the social/affordable/family housing, then every developer would just do that. This is how development pro formas work.
But at the end of the day, we are still taxing new housing and new home consumers for the purpose of trying to create a smidgen of more affordable housing. And this has never sat well with me, especially considering that there are plenty of other things that we could be doing to make new housing more affordable for everyone.

Last week I wrote about Toronto's plan to make fourplexes as-of-right across the city, but also why this form of missing middle housing shouldn't have a maximum floor space index.
Today, let's look at the numbers in a bit more detail.
If you look at a zoning map of Toronto, you'll see that many neighborhoods across the city have a maximum floor space index (FSI) of 0.6. What this means is that if you have a piece of land like this:
Lot width: 20'
Lot depth: 115'
Site area: 2,300 sf
Your total allowable gross floor area would be 1,380 square feet (0.6 x 2,300 sf).
If you build a laneway suite in this city, that won't count towards your total allowable GFA (otherwise they'd be very challenging/impossible to build). But if you want to build something like a triplex or a fourplex, it counts.
The one important caveat is that if you're building a residential building -- that isn't an apartment building with 5 or more homes -- you can deduct the floor area of the basement:

This, of course, helps the situation. But it doesn't solve all of our problems.
If you assume that the basement can be one home, that still only leaves 1,380 square feet for the other three, technically permissible, homes. This equals: 3 homes x 460 square feet.
Another option would be 2 homes x 690 square feet. But still, we're not exactly making it easy to deliver more "family-sized homes" in the city.
And herein lies one of the problems (plural, because there are others). We can say that fourplexes are allowed across the city, but it may not actually be technically feasible or practical to build them.
