One of the most important considerations for livability in a multi-family building is the elevators. And as someone who has lived in a condominium building for the last 10 years, I know firsthand that it can be frustrating when they aren’t working properly. So this is obviously something that we pay a lot of attention to in our own projects.

The very general and crude rule of thumb is that you want at least 1 elevator for every 100 homes. For example, at Junction House, we have 151 suites and 2 elevators. So that means we have 1 elevator for every ~76 homes. At One Delisle, we have 371 suites and 4 elevators. So 1 for every ~93 homes. At the same time, I live in a building with 357 suites and 3 elevators (1 for every 119), and it works just fine.

But again, this is a very general rule of thumb. There are many other factors that can influence performance such as the number of levels in the building, the number of suites per floor, the number of below-grade parking levels, and so on. In my building, we have all above-grade parking, so I’m sure that impacts things.

If you have a building with a lot of below-grade parking, that will generally decrease performance all else being equal (i.e. increase weight times). Because now you have that many more stops, even if the number of homes remains constant above.

One common way to mitigate these impacts is to add a parking shuttle elevator. This is a dedicated elevator for just the parking levels, and it’s something that you’ll often see in office buildings. This helps service levels. It can also help the overall building efficiency (saleable area/gross construction area) by potentially eliminating the need for another elevator shaft in the above-grade levels.

But the trade-off is that you now need to transfer elevators, usually at the ground floor. Some people don’t mind this and think it helps with building security. If someone sneaks into the garage, there’s another obstacle to getting up into the residential floors. But it does mean that if you’re coming home with groceries in your hands, you need to take 2 elevators.

I’d be curious to hear from all of you what you think about parking shuttle elevators in residential buildings. Because I suspect that as building heights increase and as parking ratios continue to decline, parking shuttle elevators will likely become more common in cities like Toronto. Let me know in the comments below.
