Sammamish, WA Parking Rules: EV Charging (2026)

There is no Sammamish Municipal Code provision unique to electric-vehicle charging-station parking; the city relies on Washington statute. RCW 46.08.185 governs public EV charging spaces statewide. It makes it a parking infraction, with a monetary penalty of $124, for any person to park a vehicle in a parking space served by publicly available electric vehicle supply equipment if the vehicle is not connected to the charging equipment. The statute requires publicly available charging stations to be marked with vertical signage identifying the station and indicating that the space is only for electric vehicle charging, consistent with the Manual on Uniform Traffic Control Devices adopted by WSDOT under RCW 47.36.030. Supplementary signage may state the penalty amount for parking without charging. EV charging-station installation on private property in Sammamish is handled through the standard building/electrical permit process administered by Community Development under the adopted state building and electrical codes, rather than through a parking ordinance. Drivers using public chargers in Sammamish should watch for posted signs, because enforcement of the $124 penalty depends on the required signage being present.
