One of the things I included in my list of "how to improve the feasibility of infill housing" was the adoption of single-stair buildings. So today I'm happy to share that next week the Canadian Urban Institute — in collaboration with LGA Architectural Partners — will be hosting a series of online micro-conferences covering this topic. If you're a regular reader of this blog, you'll know that LGA is one of the leading voices, if not the leading voice, advocating for this important building code change.
Here are the event posters:


And here are the links if you'd like to register for any of the sessions:
Single Stair Sessions Day 1 — "The 3 Ps: Pilot Projects and Prototypes"
Single Stair Sessions Day 2 — "The 2 Ss: Safety and Sustainability"
CityTalk | Live — "Addressing Canada's Housing Supply: Can Regulations Drive Housing Innovation?"
We are actively underwriting new missing middle housing across central Toronto. And I can tell you that project feasibility would benefit enormously from this code change. Single-stair buildings are also allowed in many/most other parts of the world, and so we already know that it can make for better homes and that it doesn't need to compromise life safety. It's great that the city-building community is now increasingly focused on this opportunity.

The province of British Columbia made the following announcement this week:
The Province has updated the BCBC to remove the [building] code requirement for a second egress, or exit, stairwell per floor in buildings up to six storeys. This change will make it possible to build housing projects on smaller lots and in different configurations, while allowing more flexibility for multi-bedroom apartments, more density within areas of transit-oriented developments and the potential to improve energy efficiency in buildings. Previously, the BCBC called for at least two egress stairwells in buildings three storeys and higher.
This is meaningful progress. And BC is the leading the way in Canada. But from a global perspective, we are not leading the way. This is us catching up.
As part of this building code change, the province commissioned a report on single egress stair building designs. In this report, they looked at various jurisdictions from around the world:
Their non-exhaustive findings:
There are at least 30 jurisdictions with SES building design requirements that permit midrise buildings with a building height of at least 5 or 6 storeys. In addition, the Center for Building in North America (www.centerforbuilding.org) reports that 8 US states have passed legislation into law, or are reviewing possible options for doing so, to allow larger SES buildings when their Building Code is next revised. In most cases these revisions are intended to allow SES buildings of up to 6 storeys.
For example, Seattle already allows up to 6 storeys. Belgium, New Zealand, and Australia allow up to 9 storeys (driven by a maximum height in meters). And Finland allows up to 18 storeys, according to the report.
Though keep in mind that building codes are complicated and often have frustrating gray areas. There may be other requirements that need to be met in order to achieve these heights.
It's great to see BC making these moves. Now watch for other provinces to follow suit.
It was not my intention to make this building code week on the blog, but for some reason that has happened. So let's continue. Here is an interesting guest essay -- about elevators -- written by Stephen Smith for the New York Times.
Stephen is the founder and executive director of a Brooklyn-based non-profit called the Center for Building in North America. And what they do is conduct research on building codes, specifically in the United States and Canada, and then advocate for reforms.
Here's what he thinks about elevators (taken from the above essay):
Elevators in North America have become over-engineered, bespoke, handcrafted and expensive pieces of equipment that are unaffordable in all the places where they are most needed. Special interests here have run wild with an outdated, inefficient, overregulated system. Accessibility rules miss the forest for the trees. Our broken immigration system cannot supply the labor that the construction industry desperately needs. Regulators distrust global best practices and our construction rules are so heavily oriented toward single-family housing that we’ve forgotten the basics of how a city should work.
Here's how the US compares to a few European countries:
Nobody is marveling at American elevators anymore. With around one million of them, the United States is tied for total installed devices with Italy and Spain. (Spain has one-seventh our population, 6 percent of our gross domestic product and fewer than half as many apartments.) Switzerland and New York City have roughly the same population, but the lower-rise alpine country has three times as many single-family houses as Gotham — and twice as many passenger elevators.
And here's a set of cost comparisons:
Behind the dearth of elevators in the country that birthed the skyscraper are eye-watering costs. A basic four-stop elevator costs about $158,000 in New York City, compared with about $36,000 in Switzerland. A six-stop model will set you back more than three times as much in Pennsylvania as in Belgium. Maintenance, repairs and inspections all cost more in America, too.
If you're interested in this topic, I would encourage you to give the full article a read. It's highly relevant to our ongoing discussions around missing middle housing. If cities, like Toronto, hope to build a lot more apartment buildings (especially smaller-scale ones), they are going to need affordable and plentiful elevator options.
