Daily insights for city builders, delivered every morning at 6 AM ET. I’m Brandon Donnelly — a Toronto-based real estate developer and founder of Globizen. I’ve been writing here since 2013.
I am positive that it had absolutely nothing to do with this post about fourplex feasibility, but I was happy to receive this notice in the mail yesterday:
It is a public meeting notice for the City of Toronto’s proposed multiplex policies (defined as duplexes, triplexes, and fourplexes). And as you can see from the highlighted section, they’re looking, among other things, to make this form of housing exempt from floor space index maximums.
Good.
I don’t like this “where applicable” business, but I’m going to conveniently ignore that for now and just say that this is positive. Removing density maximums is a mandatory ingredient for helping to make this type of housing feasible.
No FSI maximums. No DCs. And let’s modernize how HST is charged on new rental housing.
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.
Note: I am not a planner. If you are, leave a comment below.
The desire to add more housing to single-family neighborhoods will continue to pick up steam across North America. How exactly this plays out will be market specific, but in Toronto I expect to see new planning policies put in place, as well as supportive building code changes.
And this continues to happen. Right now, the City of Toronto is working on making fourplexes permissible in all low-rise neighborhoods across the city.
This is exciting. But it’s not done yet. And it’s not perfect.
The biggest change that I think still needs to happen is around maximum densities. If we actually want to encourage more missing middle housing, we need to increase the permitted FSIs or, better yet, remove them all together.
Urban planner Sean Galbraith does a good job of explaining this in NRU:
I responded to the city’s multiplex survey last night and this was one of my main comments. If you’d also like to voice your opinion, you have until March 10, 2023. Here’s the link.
This is a great diagram from Smart Density comparing the urban and regional rail networks of Toronto, London, and Paris. All are at the same scale.
What immediately stands out to me — besides Toronto’s relatively miniscule network — is Paris’ compactness. I have said this before on the blog (here, here, and here), but I will say it again: There seems to be a tendency to fetishize the scale and height of Paris.
But building height is only one component of its ubiquitous built form. Unlike Toronto, we’re not talking about midrises built up against single-family homes. Paris is far more dense and its buildings are far closer together (usually with interior courtyards)
In the world of development, there is something known as a floor space index (FSI). Some places call it a floor area ratio (FAR), but they mean the same thing. It is one measure of density. To calculate it, you simply divide the total building area by the site area. For example, if you had a 25,000 square foot piece of land and you were to build a single storey building that occupied every bit of the site (also 25,000 sf), you would have an FSI or FAR of 1.0. If you built a two storey building on only half of the site, you would similarly have an FSI or FAR of 1.0. The area didn’t change, you just moved things around. That’s how FSI’s work.
A ratio like this tells you how intensely you may be using a piece of land, but it doesn’t tell you everything or necessarily give you the full picture. Which is why I find it silly when too much emphasis is placed on this singular number. I don’t think anyone in the history of the world has ever traveled to a city — let’s take Paris — and remarked how beautiful it is because of its floor space indices. Nobody thinks like this. It’s way too esoteric. What guides our experiences is built form, the ground plane, relationships to streets, materiality, light, context, and many other important things.
To give a specific example, let’s take One Delisle. This project was in effect approved twice. After it was approved by City Council in July 2020 an adjacent land parcel was acquired. It wasn’t absolutely necessary to do this, but we felt it made for better city building and so we did it. (We wanted to look back knowing we did the right thing.) That meant that we needed to go back to Council to revise our approvals, which ended up happening at the beginning of this year (public staff report, here). There was no change to the tower and and no change to any of the key setbacks or stepbacks. But the overall FSI did go down!
Will anyone notice or care about this lower ratio? I doubt it. Which is why I think it’s silly to try and plan our cities around them. It feels like design by spreadsheet. Thankfully, I think many people recognize this.
Depending on who you ask, the current condo boom in Toronto might be viewed as either a good thing or a bad thing (most will have an opinion). Some people think we’re simply building too many condos. And that too many of them are small, crappy, and geared towards investors – as opposed to end-users.
While I do agree that we could be doing more to create complete communities – that is communities which serve everyone from young singles to families with 3 kids – I think there are also a lot of positives associated with Toronto’s condo obsession (full disclosure: I’m a real estate developer). It has made us more sustainable, more reliant on alternate forms of (non-car) transport, and it has made us a generally more exciting place to live.
But that doesn’t mean we can’t do better.
Lately I’ve been wondering about how other cities do it. Specifically, those European cities that somehow seem to always be able to build awesome housing projects. So today I thought I would pick one and profile it. What I really wish I had was a financial pro forma to share with you all, but in the absence of that, I’ll try and back into some of the numbers on my own.
Shown above is the 9-storey Charlotte Apartments in Berlin. It was developed by WI Concept and designed by Michels Architecture Office. I chose this building because I think it’s an attractive one and because it’s of the (mid-rise) scale that Toronto is trying to promote along its many avenues. Here are the stats I was able to find online:
Site area: 347 square meters / 3,735 square feet
Building area: 3,000 square meters / 32,291 square feet (says gross floor area, but I don’t know if that means the same thing as it does here)
Construction costs: €3.6 million / C$5,065,691 (as of today’s rate)
Units: 28 (sold within 1 week of launch)
Market: ~70% of buyers in Berlin are believed to be foreign investors
Now, if we were actually building a development pro forma, we’d want to get a lot more granular in our calculations than what I’m about to do. We’d want to know gross construction area, net saleable areas, and so on. But for the purposes of this post (and because I have very little information), I’m going to simplify and do a back of the napkin set of calculations.
Based on above, the FSI (or density) is about 8.65 (32,291 sf / 3,735 sf). That’s roughly in line with many of the residential developments we’re seeing in downtown Toronto. The average unit size works out to be about 1,153 sf (32,291 sf / 28 units), but in reality it would be less if that 32,291 number is truly the gross floor area. You would need to subtract the corridors and other non-saleable areas from it before doing this calc. Either way, that is big compared to most downtown Toronto condos, but small for Berlin standards according to this ArchDaily article. Finally, if we look at construction costs, we get $157 per square foot in Canadian dollars ($5.065M / 32,291 sf). That’s low. I wonder what the land costs were.
Again, these numbers are rough rough. But I wanted to try and dissect a European development project and compare it to Toronto. The most surprising figure seems to be the low construction costs. If you have any additional insights, I would love to hear from you in the comment section below.
