Parking reform unlocks more homes and great neighborhoods, while cutting red tape and excess asphalt, sprawl, and pollution.
Cities, towns, and jurisdictions around the world are adopting a powerful reform that accelerates homebuilding, eliminates red tape for small businesses, reduces pollution and sprawl, revitalizes downtowns, and streamlines permitting - at zero cost to the taxpayer.
That reform? Eliminating parking mandates - local governments' arcane and unfounded requirements that every new home or business come with an arbitrary, pre-determined number of parking spaces. These requirements hamstring local builders and business owners, drive up rents and home costs, and write sprawl into law. It's time to return 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.
In Washington state specifically, the legislature is considering a bill to do just that: the Parking Reform and Modernization, SB 5184 (companion bill HB 1299).
SB 5184 would cap excessive parking mandates both for residential and commercial construction, restoring people's ability to decide for themselves how many parking spots they need, instead of the ratios some city planner wrote down back in, say, 1963. It would also give full parking flexibility to project types that need it most, like repurposing existing buildings for cafes or apartments and building more middle housing and affordable housing, daycares, and more.

Communities considering parking reform for themselves can look to the many other jurisdictions that have already enacted it for a view into what they can expect in a world with fewer parking mandates, including:
More homes, in all shapes and sizes, from backyard cottages and duplexes to apartment buildings and affordable housing
More great neighborhoods, with creative reuse and preservation of historic buildings, smart sharing agreements for existing parking, and even conversions of parking lots to new communities of homes and shops
Less unneeded asphalt and the pollution, deadly "heat islands," and long-lasting sprawl that come with it, paving over nearby farmland and open spaces
Less red tape and costly delays for builders and city staff alike
More nimble adaptation to modern parking-lite conveniences like online shopping, remote work options, and ride-hail apps
More money in local budgets for everything from firefighting to libraries, after-school programs to parks, and other community priorities

1. More homes of all shapes and sizes
More middle housing, like backyard cottages and fourplexes
Even one parking spot can render a backyard cottage impossible to build. A study out of Kent, Washington, for example, found that 85 percent of residential properties didn't have room to add an additional parking space that local rules mandated owners to have if they wanted to build a backyard cottage.
In 2023, Washington legalized accessory dwellings along with other middle housing options like fourplexes. But unless the property is near a major transit stop, homeowners still have to meet local parking mandates, whether or not they want or need the parking.
Since neighboring Oregon implemented its sweeping parking reforms in 2023, middle housing is sprouting up that would not have been possible under prior parking rules. One project, Grant Street Grow Homes, in Eugene, Oregon, was able to add four backyard homes without demolishing the existing primary house only because no off-street parking was required. The new homes are now selling for $96,000 each to qualified buyers.
The Grant Street Grow Homes are far from outliers in the Beaver State. In Portland, 79 percent of homes permitted since the 2021 middle housing reform ...
