You just bought an electric vehicle—or you're about to. Congratulations. Now comes the question every new EV owner faces: how do I charge this thing at home?
The short answer is simple: plug it in. But if you want to actually use your car without planning your life around charging times, you need a Level 2 home charger. This guide walks you through everything—no sales pitch, just the information you need to make a smart decision.

Why Charge at Home vs. Public Stations?
Public charging works in a pinch, but it's not a lifestyle. Here's the reality:
- Convenience. Plug in when you get home, wake up to a full battery. No detours, no waiting.
- Cost. Home electricity costs about $0.14/kWh in Seattle. Public fast chargers can hit $0.40-0.50/kWh. Over a year, that adds up.
- Battery health. Level 2 home charging is gentler on your battery than DC fast charging. Your battery will thank you in year 8.
- Off-peak rates. Seattle City Light offers time-of-use rates. Charge overnight at reduced rates and save even more.
Public charging is great for road trips. For daily driving, home charging is the answer.
Level 1 vs. Level 2: What's the Difference?
Every EV comes with a "Level 1" charger—the one that plugs into a standard 120V outlet. It works. Slowly.
Level 1 (120V)
- • 3-5 miles of range per hour
- • 40-50 hours for a full charge
- • Uses standard outlet
- • No installation needed
Good for: PHEVs, very short commutes, overnight top-ups
Level 2 (240V)
- • 25-30 miles of range per hour
- • 4-8 hours for a full charge
- • Requires 240V circuit
- • Professional installation
Good for: Everyone with a full EV. This is what you want.
The math is simple: if you drive 40 miles a day, Level 1 barely keeps up. Level 2 gives you a full charge overnight with time to spare. For most EV owners, Level 2 isn't a luxury—it's the baseline.
Electrical Requirements for Your Home
This is where the electrician part comes in. A Level 2 charger needs a dedicated 240V circuit, which means we need to look at your electrical panel.
Panel Capacity
Most EV chargers need a 40-50 amp circuit. Your panel needs room for that. Here's the breakdown:
- 100-amp panel: Tight, but often workable. We may need to do a load calculation to confirm.
- 150-200 amp panel: Usually plenty of capacity. Most straightforward installs.
- Panel upgrade needed: If your panel is maxed out, we can install a subpanel or upgrade your main panel. Adds cost, but it's an investment in your home's electrical future.
Older homes in Seattle
Many homes built before 1980 have 100-amp panels or older wiring. This doesn't mean you can't get an EV charger—it just means we need to assess your specific situation. Sometimes a panel upgrade makes sense anyway for other reasons.
Circuit and Wiring
The charger needs its own dedicated circuit—no sharing with other appliances. We run new wire from your panel to wherever you want the charger. This is usually the garage, but can be a carport, driveway, or anywhere you park.
Wire gauge depends on the circuit amperage and distance from the panel. Longer runs need thicker wire. We size everything to code and for your specific charger.
The Installation Process
Here's what happens from first call to first charge:
Site Assessment
We come to your home, look at your panel, check the route to your parking spot, and discuss charger options. Takes about 30 minutes. Free.
Quote & Scheduling
We provide a detailed quote with no surprises. Once approved, we schedule the install—usually within 1-2 weeks.
Permitting
We handle the permit application with the city. This adds a few days but ensures everything is done to code. More details in the next section.
Installation Day
Most installs take 2-4 hours. We install the circuit breaker, run the wire, mount the charger, and test everything. You can watch TV while we work.
Inspection & Handoff
City inspector verifies the work. We walk you through using your new charger and answer any questions. You're charging that night.
Permits and Inspections in Seattle
Yes, you need a permit. In Seattle and most surrounding cities, EV charger installation requires an electrical permit and inspection. Here's why that's actually good:
- Safety verification. An inspector confirms the work meets electrical code. This matters when you're dealing with 240V circuits.
- Insurance and resale.Permitted work is on record. If you sell your home or file an insurance claim, there's documentation that the work was done right.
- Rebate eligibility. Many rebate programs require proof of permitted installation.
We handle the permit paperwork. The permit fee is typically $100-200 depending on the jurisdiction. Seattle has actually streamlined the process for EV chargers—they want people charging at home.
What It Actually Costs
Let's talk real numbers. EV charger installation costs vary based on your specific situation, but here are typical ranges for the Seattle area:
Typical Installation Costs (Labor Only)
Note: Charger equipment not included. You pick and purchase your own charger—you'll get a better deal buying it yourself than having us supply it. We install whatever you choose.
What affects the price? Distance from panel to charger location, whether your panel has capacity, the amperage you need, and how the wire needs to be routed (through walls vs. exterior conduit).
Most homeowners end up in the $700 - $2,500 range for installation. Add your charger cost (typically $400-700 for a quality Level 2 unit) and that's your total investment for years of convenient home charging.

Rebates and Incentives
There are programs available to offset your costs, but they've changed recently. Here's the current landscape for Seattle-area homeowners:
Federal Tax Credit (30C) — Ending Soon
30% of installation costs, up to $1,000. However, this credit ends June 30, 2026 and only applies to homes in qualifying low-income or non-urban census tracts.
Check if your address qualifies at the DOE's Alternative Fuels Data Center. If eligible, act before the deadline.
PSE Rebate (Puget Sound Energy customers)
Up to $300 rebate on a qualifying Level 2 charger. Income-qualified customers may receive up to $600 plus installation assistance up to $2,000.
Purchase through PSE Marketplace for instant rebate, or apply after purchase at pse.com.
Seattle City Light Time of Use
Optional Time of Use rates let you charge overnight at around $0.08/kWh (midnight to 6am)— significantly cheaper than daytime rates.
Standard residential rate is around $0.14/kWh flat—still cheaper than public charging.
Rebate programs change frequently. We stay current on available incentives and can help you understand which programs you qualify for during your free assessment.
Choosing the Right Charger
There are dozens of Level 2 chargers on the market. Here's what actually matters:
Amperage (Speed)
Most home chargers are 32-48 amps. Higher amps = faster charging, but also requires a larger circuit. For most people, a 40-amp charger on a 50-amp circuit is the sweet spot—fast enough for overnight charging, reasonable installation cost.
Hardwired vs. Plug-In
Hardwired chargers connect directly to the circuit—cleaner look, slightly more reliable. Plug-in chargers use a NEMA 14-50 outlet—easier to swap out or take with you if you move. Both work great. We install either.
Smart Features
WiFi-connected chargers let you schedule charging, track energy use, and get notifications. Nice to have, not essential. Your car can also schedule charging if your charger can't.
Brands We Recommend
We install ChargePoint, Grizzl-E, Emporia, and JuiceBox regularly. All solid choices with good warranties. We're brand-agnostic—we'll help you pick what makes sense for your situation and budget.
Frequently Asked Questions
Can I install an EV charger myself?
Technically, some plug-in chargers can be DIY if you already have a 240V outlet in the right spot. But running a new circuit? That requires a permit and licensed electrician. And honestly, for something your family will use daily for years, professional installation is worth it.
What if I have two EVs?
We can install two chargers, or use a charger with load-sharing capability that splits power between two vehicles. Depends on your panel capacity and how you use the cars.
Can I charge in the rain?
Yes. All outdoor-rated Level 2 chargers are designed for weather exposure. The connectors are waterproof. We install chargers outside all the time—this is Seattle, after all.
How long does installation take?
Most installations take 2-4 hours. Complex jobs (long runs, panel work) can take a full day. We'll give you a time estimate with your quote.
Will this increase my home's value?
Studies suggest homes with EV chargers sell faster and for slightly more, especially in EV-heavy markets like Seattle. It's becoming an expected feature for many buyers.
