HB 1110 addresses the state’s acute housing shortage, opening up affordable options for families, workers, and elderly and young home seekers.
Will 2023 be the year that Washington state opens up more housing options for families and individuals here? The year it joins other West Coast states to end widespread bans on every kind of home except detached houses with big yards?
Legislators tried last year, and this year are back with another bill, HB 1110, to lift local zoning laws that ban multi-dwelling homes like duplexes and townhouses. It would open the doors to “middle housing” options for hundreds of thousands of families, legalizing up to fourplexes all on residential lots in most cities, and sixplexes near transit stops.
By legalizing more housing options in neighborhoods throughout the state, the bill would not only help correct the historic injustice of restrictive zoning originally enacted to exclude Black families, but also relieve the root cause of Washington’s housing crisis: a shortage of homes.
More middle housing means more affordable home choices near jobs, schools, and transit, and more options for first-time homebuyers. It also means a wide range of other benefits to Washingtonians, including less sprawl into our farmland and forests, more walkable communities, reduced home energy use, lower municipal infrastructure costs, jobs for small, local builders, and increased local tax revenue.
HOW MIDDLE HOUSING CAN EASE THE HOUSING SHORTAGE
Washington officials project that the state will need roughly one million new homes by 2044. The pro-housing nonprofit group Up for Growth estimates the state’s shortage of homes rose from 64,000 in 2012 to 140,000 in 2019—more than doubling in just 7 years.
Compared with typical apartment buildings, middle housing yields fewer homes per lot, but there’s power in numbers: Washington has about 1.8 million detached houses occupying roughly three-quarters of the state’s residential land. If middle housing were legalized, only a fraction of those house lots would gain new homes, but that small share would still be enough to help pull Washington out of its housing shortage.
Extrapolating from a California study, legalizing fourplexes throughout Washington could make more than 200,000 more homes not only legal, but also financially feasible for builders to construct.
A University of Washington report estimated that legalizing fourplexes within a quarter-mile of transit stations would create capacity for nearly half a million more homes in the Puget Sound region, which houses 4.3 million of the state’s 7.6 million residents. If even a fifth of that capacity eventually saw construction, that’s 100,000 more homes in the Puget Sound region alone.
Detailed projections are not available for the 2023 middle housing bill, but we know that it will legalize the potential for hundreds of thousands more homes for individuals and families that need them all across the state.

BREAKING DOWN HB 1110, WA’S 2023 MIDDLE HOUSING BILL
Continuing her strong leadership on housing, Representative Jessica Bateman is the prime sponsor of this year’s bill, HB 1110, that would legalize middle housing in two tiers:
Within a half-mile of frequent transit, up to six homes per lot
In cities with a population of 6,000 or more, or cities of any size within the contiguous urban growth areas surrounding Seattle or Spokane, up to four homes per lot
Applies to small cities located within major metros
A key change from the 2022 bill is that fewer cities would be exempted based on population. The bill applies to cities as small as 6,000 (the cutoff in last year’s bill was 20,000).
In addition, cities smaller than 6,000 will not be exempt if they lie within an urban growth area contiguous with a city that has population of at least 200,000, which translates to the Seattle and Spokane metros. This would en...
