This is a good follow-up to my recent post about the barriers to developing mid-rise here in Toronto. I have just learned (thanks to Michael Mortensen) that Vancouver has proposed some specific zoning changes that are intended to increase the supply of new rental housing.
Oddly enough, some of these proposed changes are consistent with what I put forward in my post and include 1) streamlining the development approvals process and 2) simplifying the allowable built form. i.e. Fewer step-backs.
Here's a capture from the report that went to City Council:
Lots sizes and dimensions vary from city to city, as well as from neighborhood to neighborhood. They come in many different shapes and sizes from long and narrow (common in Toronto) to rectangular or even wide and shallow. Charlie Gardner wrote a terrific post on this last year where he used Bing Maps to illustrate some of these differences. Tokyo, for instance, is shown as having more rectangular lots (32′ x 38′), whereas Buffalo is shown as having more long and narrow lots (30′ x 175′). Charlie then asks: why the prevalence of inefficient long and narrow lots? These dimensions obviously produce long and skinny houses.
As he rightly points out in his post, there are economic reasons for this. Assuming you’re starting with deep blocks and lots, then there’s going to be a natural tendency toward subdividing and going long and skinny. That’s because the key dimension is frontage onto the street. The more frontages you create, the more front doors can be built, the more lots with access to the Mississippi can be created, etc. And that’s how you end up with 10-12′ wide row homes, which also helps to address overall housing affordability. This is not a new phenomenon.
To further demonstrate this point, let’s look at how this phenomenon has translated into the condo market – specifically the mid-rise condo market here in Toronto. In this case street frontage morphs into window frontage (access to light). That’s now the guiding dimension. In a 1 bedroom apartment, that dimension might be something around 6-7m. That allows you to have both a bedroom and a living room with a window. So it makes for a great 1 bedroom or 1 bedroom + den apartment. (I’m ignoring corner suites for this thought exercise.)
