Washington Housing Bills to Watch in 2025
More than two dozen bills aim to unlock great neighborhoods, greater affordability, and less red tape for Washingtonians.
Washingtonians from Spokane to Sequim, Washougal to Wenatchee, are struggling to afford homes and rents in their communities due to a deep housing shortage. While recent years' laudable legislative actions have begun to relegalize more homes, in all shapes and sizes, it will take years of dedicated effort to make up for decades of stunted homebuilding in cities and towns. It will also take a series of smart policy upgrades to correct for all the restrictions that have outlawed anything but the most expensive kind of housing in the residential neighborhoods of Washington's cities: single-detached houses on their own exclusive lots.
Legislators are considering numerous bills in Olympia this year to do just that. Below Sightline catalogs the ones we're watching and, in many cases, weighing in on. The first several are our highest priorities for the 2025 legislative session.

Sightline's priority bills
Free communities from costly parking mandates | SB 5184, HB 1299
Sponsors: Sen. Bateman, Rep. Peterson
Parking mandates are local governments' requirements that every new home or business come with an arbitrary, pre-determined number of parking spaces. From bowling alleys to churches, daycares to moth breeding facilities (yes, really), these excessive prescriptions drive up the cost of new homes, businesses, and community resources at a time when Washington urgently needs more of all of these things. It writes sprawl into law and makes it harder to build the great neighborhoods and Main Streets people love in their communities.
The Parking Reform and Modernization Act would cap residential and commercial mandates and provide full parking flexibility for projects like daycares, senior housing, affordable housing, and other building types that need it most. To be clear, the bill does not bar anyone from building as much parking as they like as part of their project. Rather, it returns these decisions to the people investing in their communities, whether a homeowner, homebuilder, or entrepreneur, who are best positioned to know how many parking spaces they need for their dream to succeed.
Incentivize transit-oriented development with smart funding tools | SB 5604
Sponsor: Sen. Liias
Transit-oriented development (TOD) is a strategy of building more homes near transit hubs so people can live closer to and more easily access the places where they work, learn, and recreate. Pursuing this strategy in Washington in particular would make the most of the state's large public transit investments in recent years.
With these benefits in mind, SB 5604 would establish several new ways for the state to incentivize TOD. But unlike typical TOD bills it does not address zoning at all. For new housing developments in transit station areas, it would create special property tax abatements, sales tax exemptions, lower excise tax rates, and reduced impact fees, along with associated affordability requirements. It's designed to complement TOD zoning, existing or future.
High interest rates and construction costs have made apartments difficult to finance, and future permitting has plummeted in cities throughout the state. That's why SB 5604 focuses on helping housing development pencil. It doesn't rezone because that's not the limiting factor at most major station areas in Washington metros.
Legalize abundant, affordable apartment homes near transit | HB 1491
Sponsor: Rep. Reed
Similar to Washington's 2024 TOD bill, HB 1491 would legalize larger apartment buildings near major transit stops, with stipulations that some of their units meet affordability mandates - known as inclusionary zoning (IZ). Setting statewide minimum standards for multifamily zoning near transit is a key piece of the TOD puzzl...
