EV Charger Installation Requirements: 7-Step Checklist Before Your Electrician Arrives

1Know where you want the charger mounted

The charger should be within cable reach of your car's charge port. Most cars charge on the driver's side front or rear — measure from your typical parking spot to the wall. A garage stud wall is the easiest mount; drywall or brick requires specific anchors. Decide before the electrician arrives so they can plan the conduit run.

2Locate your electrical panel and note its capacity

Know where your main panel is and whether it has open breaker slots. A 40A EV charger needs a dedicated 50A double-pole breaker. A 48A charger needs a 60A breaker. If your panel is 100A or older and mostly full, flag this when getting quotes — your electrician needs to assess load before quoting a final price.

3Decide: plug-in (NEMA 14-50) or hardwired

A NEMA 14-50 outlet costs slightly less to install and lets you unplug the charger if you move. A hardwired installation is code-required in some jurisdictions, looks cleaner, and is more permanent. Most EV owners in long-term homes choose hardwired. Ask your electrician which is allowed under local code at your address.

4Check for utility rebates before buying

Many utilities — PG&E, Duke Energy, Xcel Energy, and others — offer $100–$500 rebates on EV charger installations, but some require a specific approved charger model or a connected (Wi-Fi) unit. Check your utility's website before purchasing hardware. See our state-by-state rebates guide for current programs.

5Confirm your charger model with the electrician ahead of time

If you're supplying the charger, share the model number with your electrician before the install date. Different chargers require different wire gauges (6 AWG for 40A, 4 AWG for 48A/60A) and breaker sizes. An electrician who shows up without the right materials will need to reschedule — a quick confirmation call avoids that.

6Clear the installation area

Move anything stored against the wall where the charger will be mounted. Give the electrician unobstructed access to both the mounting wall and the panel. If the conduit run goes through a finished wall or ceiling, they'll need access to that path. The cleaner the workspace, the faster the job.

7Ask about the permit and inspection process

A licensed electrician will pull the permit and schedule the inspection. Ask upfront whether the permit fee is included in the quote. After installation, the inspector will visit (often within 2–5 business days) to sign off on the circuit. You don't usually need to be home for the inspection if the panel is accessible.

How long does EV charger installation take?

Most residential EV charger installations take 2–4 hours once the electrician is on-site. If a panel upgrade or subpanel is needed, the same-day timeline extends to 4–8 hours. Permit inspections, when required, typically happen within a few days of installation.

Do I need a permit to install a home EV charger?

In most jurisdictions, yes. A dedicated 240V circuit for an EV charger is a new electrical circuit and requires a permit and inspection. A licensed electrician handles the permit application as part of the job. Skipping the permit can create issues with home insurance claims and future home sales.

What should I tell the electrician before they arrive?

Let them know where you want the charger mounted, which side of the garage your car charges from, your panel location, and whether you've chosen a specific charger model. If you already own the charger hardware, confirm with them beforehand that it meets local code.

Do I need to buy the charger before hiring an electrician?

No — many electricians supply and install the unit as a package. This can be convenient, but buying your own charger gives you more model flexibility. Either way, confirm the charger model with your electrician before the install date so they can bring the right wire gauge, breaker, and conduit.

What if my electrical panel is full?

A full panel doesn't automatically block an EV charger installation. Options include load management devices that share existing capacity, adding a tandem breaker if slots exist, or installing a subpanel. Your electrician will assess the panel during a site visit and recommend the right approach.

Can I install an EV charger in a rented home or apartment?

It depends on your lease and local tenant laws. Some states require landlords to permit EV charger installation if the tenant pays for it. In all cases, you'll need written landlord approval before an electrician can do any work. See our EV charger for renters guide for state-by-state rules.
