One of the big housing trends that we have seen across North America over the last several years is the push to allow greater supply in low-rise neighbourhoods.
Here in Toronto, this has come through a well-known program called Expanding Housing Options in Neighbourhoods (or EHON), which I believe launched around 2020. But you can find countless similar programs in other cities.
Salt Lake City, for example, is currently looking at updating its single-family exclusive zoning to allow for "gentle infill opportunities" on smaller lots. The zones under consideration cover 77% of the land zoned for residential in SLC. And interestingly enough, this program is also called Expanding Housing Options.
In their case, they are proposing to create a new definition for "Small Lot Dwellings," which would, among other things, reduce the minimum lot area per dwelling to 2,000 sf, reduce the number of required off-street parking spaces from 2 to 1 per dwelling, and allow up to four homes per lot via fourplexes and townhomes.
One of the things that I found interesting about their proposed policies is that they seem to explicitly encourage "sideways" multiplexes and row houses like this:
This starts to tell you something about the scale of SLC's urban fabric, even though there are no dimensions on this conceptual site plan. These are big lots.
Despite sometimes having the same moniker, cities are responding to their urban contexts in different ways. SLC uses explicit density math: at least 2,000 sf of site area per dwelling. Whereas Toronto increasingly relies on built-form standards: here's the envelope you can build, if you can fit a fourplex within it (or a sixplex in certain wards), go for it. And don't worry about parking.
If Toronto mandated one parking space per dwelling unit, virtually no multiplexes would ever get built in the city. Our lot sizes simply don't allow for it. Moving away from the car is also the only way that Toronto will be able to continue to grow and scale up.
Despite these local nuances, the overall ambition remains the same. Low-rise neighbourhoods across North America are being asked to house more people on the same amount of land, and that's a positive step forward.

This is the sort of housing project that you'd fully expect to find in Tokyo. Seven homes built on a small urban lot measuring only 11 feet wide by 93 feet deep. But in this case, it's not Tokyo; it's Chinatown, Philadelphia, where a residual lot that was created when the sunken Vine Street Expressway was carved through the middle of the city in the 1950s.
Designed by Philadelphia-based Interface Studio Architects (ISA), the project contains 7 levels of livable space. What's interesting, though, is that from a building code perspective this is still a 4-story building. There are two mezzanine levels that don't get counted (and that create some great double-height spaces). This also seems to be what allowed them to get away with a single egress stair in the middle of the building.
The other technique that was used to maximum density is facade projections. Philadelphia's zoning code allows for projections up to 3 feet in the horizontal dimension. And if you look at the above plans, you'll see that these were used to "top up" or extend the site's 11 foot width to 14 feet, when it made sense to do so from a programming standpoint. The result is some very livable spaces.
I am endlessly fascinated by these sorts of projects because they demand creativity and because you ultimately end up unlocking something that the market had been overlooking. Here is an example of a small leftover urban parcel that was previously used as surface parking for two cars. Now it's seven beautiful homes.
