I think the demand side for single family housing will increase in Seattle over the near future. There has been a recent boom in tech company positions and equity (especially Amazon and Microsoft, but others as well such as Tableau, Facebook, etc.). There is a relatively (compared to SF) nascent startup and VC scene developing, and more tech companies are opening or expanding branch offices here as they observe the talent pool that's now well above critical mass. And many employees of these companies are young (in their 20s), recent transplants from around the country, or on temporary work visas and in the process of getting green cards / citizenship. Seattle is also a place people tend to want to plant roots (for the great career options, the natural beauty, and the culture).

As the young recent transplants build their savings and seek to plant roots and start families when they get into their 30s, they'll look at single family housing. But the natural beauty includes water on two sides of the city and there is basically no undeveloped land to add more single family houses. Combining these employment, demographic and geographic factors, I expect demand to continue surging forward and supply to remain constrained. Building up and new apartments coming online is starting to reduce pressure on soaring condo/apartment rent costs, and building up to increase supply is a valve that can continue to reduce rent pressure for those without families. But I don't see a way forward to increase single family housing inside the city limits - in fact supply will go down as more townhomes and apartment buildings go up.

It seems, as the article hints at but doesn't much explore, that American Millenial coastal urban dwellers will need to develop a new conception of family housing (that is not single family housing with a private yard). I think there are options here, and the conception of the American dream replete with single family housing around an urban core seems like a relatively recent post-war phenomenon. What does family housing in Tokyo look like? In dense European cities? Historically before the 20th century? What new forms could it take, especially as we build up and think about modern amenities? With new transportation options (ride sharing, better bike infra, soon self driving cars) garages are less necessary, with new meal delivery options kitchens are less necessary, and with the sharing economy we can cut down on storage space. I'd like to see some new creative approaches to modern US family housing.
