Seattle is one of the top EV cities in the country — and charging at home is by far the cheapest and most convenient way to own one. Here's what actually goes into a safe, code-compliant home charger installation, from a local electrical contractor that installs them every week.
Level 1 vs Level 2: what you actually need
Level 1 (a standard 120V outlet) adds only a few miles of range per hour — fine for very light driving. Level 2 (240V) is what most Seattle homeowners install: it typically fully recharges overnight. That's either a hardwired wall charger (like the Tesla Wall Connector) or a NEMA 14-50 outlet for a plug-in charger.
Hardwired charger or 240V outlet?
Will your panel handle it?
A Level 2 charger is one of the largest loads in your home. Before installing, a licensed electrician runs a load calculation. Three outcomes are possible:
Permits: yes, they're required
In Washington, EV charger circuits require an electrical permit and inspection — in Seattle through the city, elsewhere through WA L&I. Galaxy Electric pulls the permit, does the install to code, and meets the inspector. That paper trail matters for insurance and resale.
What a typical install day looks like
Most installs are finished in a single visit. Longer cable runs, finished walls, or detached garages add time and cost — which is why we quote after seeing photos or the site.
FAQ
Can I just use a dryer outlet?
Sharing a dryer circuit is against code without a proper splitter device and often unsafe. A dedicated circuit is the right way.
Outdoor installation — is that OK in Seattle weather?
Yes. Wall Connectors and weatherproof outlets are rated for outdoor use when installed correctly.
Do you install home batteries too?
Yes — see our Tesla wall battery installation and backup power services.
