New state parking law: What it means for Renton
Renton must update its parking rules
In 2025, the Washington State Legislature adopted the Parking Reform and Modernization Act (ESSB 5184). The law requires cities with more than 50,000 residents to reduce certain minimum off-street parking requirements. This will include Renton (population: roughly 109,700).
These updates are mandatory under state law and must be implemented by January 2027.
What the state law requires
The law limits the amount of parking that cities are allowed to require. It also establishes several situations in which cities may not have any minimum parking requirements. Renton must revise its development regulations to match the following standards. These changes do not affect parking requirements under the Americans with Disabilities Act (ADA), which remain in effect. Changes include:
Maximum parking that cities can require:
Multifamily housing: up to 0.5 spaces per dwelling unit.
Single-family homes: up to 1 space per home.
Commercial space: up to 2 spaces per 1,000 sq. ft.
Cities cannot require parking for the following:
Homes under 1,200 sq. ft.
Commercial spaces under 3,000 sq. ft.
Affordable housing.
Senior housing.
Licensed childcare centers.
Ground-floor commercial uses in mixed-use buildings.
Projects converting from non-residential to residential (or to commercial).
What this means for future development in Renton
Renton meets the state’s population target; therefore, the city must update its residential and commercial parking standards so they align with all requirements of ESSB 5184. These updates must be adopted by January 2027. Once adopted:
The city cannot require more parking than the state allows.
Developers may choose to build more parking than required, based on project needs and market demand.
Parking requirements will still vary depending on project size, use, and the standards established by the state.
The city's role
Renton’s role is limited to:
Updating the Renton Municipal Code to comply with state law.
Reviewing applications based on the new standards.
Maintaining ADA compliance.
Evaluating opportunities—within state constraints—to address parking needs through time-limited parking spaces and loading zones for deliveries and multifamily move-in/move-out activities.
We want to hear from you
Although the city must adopt these state-required changes, community perspectives are important to help us understand local concerns and guide implementation within the limits of state law.
These questions can help inform future parking regulations.
All images are illustrative only and do not depict compliance with parking, building design, or other development standards.

Share The City should challenge this in Court. This is a clear overreach of State government in an area where the State has no vested interest.

Thank you for sharing your perspective and providing specific details regarding your neighborhood.
ESSB 5184 is a state law adopted by the Washington State Legislature, and Renton is required to update its development regulations to comply with these standards by January 2027. Currently, the City is focused on the mandatory implementation of this state law.
We understand your concerns regarding local neighborhood characteristics and transit access. While the law limits the City’s ability to mandate parking in certain situations, it does not prevent developers from providing parking based on project needs, market demand, or financing requirements. Local insights like yours are valuable as they help staff and the Planning Commission understand how these state-wide changes may impact different areas of Renton during the implementation process.

Thank you for your inquiry.
The Washington State Legislature adopted ESSB 5184 as part of an effort to reduce regulatory barriers associated with housing and commercial development. The state determined that, in some cases, existing parking requirements could:
• Increase development costs
• Reduce site flexibility
• Limit the amount or type of housing and commercial space that could be built
As a result, the law places limits on the amount of parking cities may require and establishes situations where minimum parking requirements are no longer allowed. Renton is required to update its regulations to comply with these state standards by January 2027.

While state law now limits the City’s ability to require minimum parking in many cases, the City can still support the provision of parking through voluntary approaches and code flexibility. Some potential approaches include:
Development Incentives: The City may consider incentives for projects that provide parking even where none is required, such as offering flexibility in other development standards.
Design Flexibility: The City could allow for more creative building or site design standards to make it easier for developers to include parking where it makes sense for their specific project.
As code updates move forward, the City’s approach is focused on aligning with state requirements while allowing the market to provide parking where demand exists. No specific incentives have been adopted at this time, and all community input will continue to be considered as part of this ongoing process.
