Washington State Code Change Proposes New EV Charging Standards and Definitions

Washington's Building Code Council has made significant strides in updating regulations for electric vehicle (EV) charging infrastructure during their recent meeting on July 25, 2025. The council approved a proposal that clarifies definitions and modifies requirements for EV-ready and EV-capable parking spaces, aiming to better align with future vehicle trends and state mandates.

One of the key outcomes of the meeting was the revision of definitions for EV charging, EV ready, and EV capable. The council emphasized the importance of clarity in these terms, which are crucial for developers and builders. The updated definitions now align more closely with national standards, ensuring consistency across codes.

In terms of requirements, the council decided to adjust the percentages of parking spaces designated for EV charging. The proposal reduces the requirement for EV-ready spaces from 25% to 10%, while increasing the EV-capable spaces from 25% to 40%. This change reflects a strategic approach based on projections from the Northwest Power and Conservation Council regarding the anticipated growth of electric vehicles on the road.

The council's decision is rooted in a long-term vision, with the aim of accommodating 20% of parking spaces for EV-ready and EV-capable vehicles by 2030, and 60% by 2045. This forward-thinking approach not only supports the state's commitment to zero-emission vehicles but also considers the economic implications for developers, as installing conduit for future wiring is less costly than retrofitting spaces later.

Additionally, the council discussed the terminology used in the proposal, particularly the distinction between "required" and "provided" spaces, which will be further clarified in future discussions.

These updates are expected to enhance the infrastructure necessary for the growing number of electric vehicles, ultimately benefiting Washington residents by promoting sustainable transportation options. The council's proactive measures reflect a commitment to adapting building codes in line with evolving environmental standards and community needs.
