I got a notice in the mail this week for a public meeting related to Toronto's multiplex zoning by-law. Multiplexes are house-like buildings with two, three or four dwelling units. This housing type became newly permissible across the city in May 2023, but as part of the approval, the city was asked to keep an eye on things and report back on anything that might need to be changed. What is now being proposed are amendments to this original by-law.
One change is the introduction of the term "houseplex." This is meant to get away from unit-specific terms like duplex, triplex, and fourplex; but it also sounds like it was designed to placate single-family house owners. Another proposed change is a limit on the number of bedrooms in a building. For houseplexes with three or more units, the maximum number of bedrooms is proposed to be 3 x the number of dwelling units. This is designed to block rooming houses.
It's a reminder that zoning is, at least in this part of the world, about fine-grained control. It's typically about narrowing the universe of options down to a minimum so that it's clear what we can expect. This is why zoning by-laws have things called "permitted uses." It's a strict list of things you can do. And if it's not on the list, it's off limits. A different and more flexible approach would be to do the opposite: list only what you can't do. This broadens the universe of possibilities, but gives up some control.
Roughly speaking, this is how zoning works in Japan. Land use planning starts at the national level, as opposed to being strictly delegated to local governments. And from my understanding, there are 12 main zones, ranging from exclusively low-rise residential to exclusively industrial. (Here's an interesting undergraduate paper I found on the topic.) What's fascinating about this system is that it's organized by nuisance or intensity level, and it works cumulatively.
Meaning, as you move up in allowable nuisance, things of lesser intensity still tend to be allowed. For example, just because you might have a commercial zone with restaurants and department stores, it doesn't mean you still can't build residential. It's a less intense use. At the same time, the starting point is also more permissive, because even the exclusively low-rise residential zone allows "small shops or offices." What all of this creates is a planning framework where most zones are by default mixed-use.
This is a fundamentally different approach. It relinquishes some degree of control, embraces more flexibility, and accepts that cities are chaotic living organisms. It's impossible to draw lines on a map and figure out exactly where each permitted use should go. We'll never get it right and/or keep up. What this means is that we're artificially stifling our cities by not just focusing on the obviously bad stuff (like heavy industry next to a daycare), and letting the market decide where a ramen stand should go.

The Frank Gehry-designed Grand LA is a prominent mixed-use development in downtown Los Angeles that sits across from the celebrated Walt Disney Concert Hall (which was also designed by Gehry). Developed by Related, the project occupies an entire city block and contains a 305-room hotel by Hilton, 347 luxury rental apartments, 89 affordable apartments, and over 164,000 sf of retail space.
According to Bloomberg, most of the project is doing quite well. The hotel occupancy rate is at 69%, the hotel restaurant is busy, and the residential is more than 95% leased. The problem is the retail.
Since the project opened in 2022, most of it has gone unleased. Though two new anchors were just announced: an AI museum called Dataland and a permanent home for the University of Michigan's Ross School of Business, which runs an executive MBA program in LA.
But these aren't traditional retail tenants. And it's almost certainly not what was being modeled when the project broke ground in 2019. Back then, everyone was still going into the nearby offices. And those humans would have brought foot traffic. This is one of the tricky things about development — you end up building through different macro environments.
But even in the best of times, it's generally hard to say with exact precision what will be successful. That's development. If there's comparable product, then you can comp against that (less risk). But if there isn't (more risk), you're faced with the question: Does comparable product not exist because there's no market for it, or does it not exist simply because nobody has done it yet?
If you're developing, it's because you believe the latter.

I love Toronto. It's my favorite city. And every so often, there will be a moment that explicitly reminds me why I love it so much. That happened yesterday when I walked down a laneway off College Street to find a somewhat hidden sushi spot called Oroshi Fish Co. Right away I was delighted by the combination of the small street and the mix of uses housed on it. But then, I walked inside to find two guys manhandling the carcass of an enormous bluefin tuna, and that's when I really said to myself, "man, Toronto is awesome." The sushi is some of the best you'll find in the city.
