Washington-Specific Installation Considerations
- Washington EV incentives have changed: the state sales-tax exemption on EVs expired July 31, 2025 and has not been renewed, so a purchase today pays full sales tax. Leases signed before that date can still claim it through July 31, 2028. Utility rebates from PSE and Seattle City Light are where the current savings are - confirm amounts with your utility.
- 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.

"I built ChargeRight because I was tired of seeing homeowners pay $2,000 to $4,500 for panel upgrades that a $49 load calculation would have shown they didn't need. The math doesn't lie. Every homeowner deserves to see it before they write a check."
