Cities with the highest single-room housing % in 2022

[mhays]

A 450-sf studio might be expensive vs. half of a 900-sf two-bedroom...but you can also get a 300 sf studio. Or a 150 sf bed/bath in a congregate building (SRO).

Washington State just legalized congregate housing / SROs statewide (anywhere that allows multifamily iirc). Seattle used to allow them a decade ago and they were hugely popular, all the way down to 90-sf bedrooms with bath and kitchen down the hall. These aren't for everybody, but they're the only way you can build market-rate housing that's affordable for single service workers without subsidy. The new version will require bathrooms but the kitchens can be shared.
