THE SHORT ANSWER
Yes. In Washington, a new 240-volt circuit for a Level 2 charger needs an electrical work permit and an inspection. In Benton County those go through the Department of Labor & Industries (L&I). Plugging the cord that came with your car into an existing 120-volt outlet (Level 1) doesn't need a permit. Richland's $300 charger rebate also requires the permit and a passed inspection.
When you need a permit
The rule of thumb is simple: new 240-volt wiring means a permit.
| Your setup | Permit needed? | Why |
|---|---|---|
| Level 1: car's cord in an existing 120-volt outlet | No | No new wiring. |
| Level 2 plug-in: new 240-volt outlet (NEMA 14-50) | Yes | A new 240-volt circuit is electrical work that needs a permit and inspection. |
| Level 2 hardwired charger | Yes | Same new 240-volt circuit, wired straight to the charger. |
| Panel or service upgrade for a charger | Yes | Panel and service work needs its own permit and inspection, and service upgrades involve the utility. |
Who pulls the permit?
Under Washington's electrical rules, whoever does the electrical work is responsible for the permit. When you hire an electrical contractor, they pull it as part of the job. Ask about it when you get a quote: a price with no permit included is a red flag.
Washington rules also say the permit has to be posted before the inspection, and new work can't be energized or connected until a valid permit is in place.
What the inspector checks
An inspector is making sure the circuit is sized and installed safely for a load that runs for hours at a time. Typical checks include:
- Breaker and wire size. EV charging counts as a continuous load, so the circuit is sized at 125% of the charger's output. A 48-amp charger needs a 60-amp circuit; a 32-amp charger needs a 40-amp circuit.
- Panel capacity. Whether your service can carry the charger along with everything else in the house.
- Installation. Mounting, wiring method and connections that follow the charger maker's instructions and the electrical code.
Why the permit matters beyond the law
- Rebates. Richland's application asks for the L&I permit and passed inspection report.
- Selling your home. Unpermitted electrical work can come up in an inspection when you sell.
- Insurance. A permitted, inspected install is a clean record if anything ever goes wrong.
Skipping it can bring a stop-work order, correction work and re-inspection fees.
