Seattle also has a growing affordability problem and is in the same zoning situation as SF or Vancouver.

Here's the official zoning map showing the absolute domination of single-family zones: http://www.seattle.gov/dpd/Research/gis/webplots/smallzonema...

And an article with commentary on how much of Seattle is zoned for single-family home only: https://www.seattletimes.com/business/real-estate/amid-seatt...

Something needs to give.
