Washington-Specific Installation Considerations
- Washington has strong EV incentives — no state sales tax on EVs under $45,000 MSRP, plus utility rebates from PSE and Seattle City Light.
- Rain doesn’t affect charging — all UL-listed Level 2 chargers are rated for outdoor use. Garage installations are standard but not required.
- Seattle’s older housing stock — homes in Capitol Hill, Fremont, and Wallingford may have 100A panels. East side suburbs (Bellevue, Redmond, Kirkland) are predominantly 200A.
- Permits required — most Washington jurisdictions require an electrical permit for EV charger installation.
