Washington County, OR Parking Rules: EV Charging (2026)

6 governs electric vehicle charging parking spaces, either public or private, wherever a development chooses to provide them; the county does not require EV charging as a condition of a parking area, but once a project includes charging spaces they must meet four standards. 1 at a 1:1 ratio, so an EV charging stall counts as a regular required space rather than an add-on. Subsection B requires a minimum of one electric vehicle charging space to be ADA compliant, ensuring accessible charging is built into any installation rather than left optional.

Subsection C requires posted signage identifying each space, capped at not to exceed 5 square feet in size, keeping wayfinding compact rather than turning into an additional freestanding sign under Section 414. Subsection D sets physical placement limits for the charging hardware itself: electric vehicle charging unit outlets and operable parts shall be no less than 18 inches off the ground if indoors and 24 inches off the ground if outdoors and no higher than 48 inches off the ground to ensure easy access, a band designed to keep controls reachable while limiting exposure to water pooling or vehicle contact at grade. 5-foot minimum stall width and applicable aisle clearances as a standard space in the same lot.
