Co-living is an affordable, flexible, community-forward type of housing that serves diverse needs for people in all stages of life.
The remedy for Washington's dire housing shortage is more homes of all shapes and sizes. Co-living homes - small apartments with shared kitchens - are a low-cost housing option that most communities lack because local zoning laws make them illegal or otherwise impractical to build. A new Washington bill, HB 1998, aims to fix that by setting standards to legalize co-living homes statewide.
The potential affordability payoff is big. Rents in newly constructed, market-rate co-living homes in the Puget Sound region can be affordable to people earning as low as 50 percent of area median income, without any public subsidy. From 2014 to 2016 in Seattle, co-living accounted for fully 1 in 11 of total new homes built, before the city's ill-advised raft of new restrictions all but killed off co-housing construction. We can learn a lot from that instance - and apply the lessons statewide in a way that's right for the variety of Washington communities.

WHAT ARE CO-LIVING HOMES?
Co-living homes are a low-cost, multifamily housing option in which each resident has a small, private living and sleeping room and shares with other building residents a common kitchen and other spaces. The housing type is also known as single-room occupancy (SRO), congregate housing, rooming houses, micro-housing, or residential suites.
Technically, the defining feature of co-living homes is that individual rooms - "sleeping units," in building code-speak - do not have full kitchens (but often have their own "kitchenette," with a mini-fridge, double burner, and/or microwave). In co-living homes built within the past couple decades, the sleeping units almost always include their own full bathroom, though historically, shared bathrooms were not uncommon. Modern buildings often also have shared recreational spaces. The private sleeping rooms are typically 150 to 230 square feet.
Over recent years in Washington, what little new construction of co-living homes that has occurred has been in Seattle, along with a sprinkling in a few nearby cities. The buildings can be large, with up to a few hundred sleeping units, but more commonly fall in the range of 20 to 40, built on small infill lots. Occupancy rates tend to be similar to standard apartments. See examples in Seattle (here and here), Kirkland, Redmond, and Shoreline.
CO-LIVING HOMES: GOOD FOR PEOPLE, POCKETBOOKS, AND THE PLANET
Co-living homes are a housing choice that's desirable for people in a variety of stages of work and life, like:
Renters who want a small, low-cost rental, possibly while saving to purchase a home;
Residents who wish to trade off square footage for location in a neighborhood they couldn't otherwise afford;
People who like shared community spaces, like courtyards, kitchens, and lounges, that facilitate social connections;
Single seniors who want to downsize and appreciate the alternative mobility options often available near co-living homes (AARP, for one, also supports Washington's co-living bill); and
Individuals who want a more private alternative to living with roommates in a traditional rental, which frees u...
