Do I Need a Permit for an EV Charger?

Whether you need a permit for a home EV charger depends on how it gets its power. A Level 1 charger that plugs into an outlet you already have is just an appliance on an existing circuit. A Level 2 charger runs at 240 volts and draws a heavy current for hours at a time. Installing one almost always means a new circuit, a new breaker, and sometimes a bigger electrical service, and building departments permit and inspect that work.

The U.S. Department of Energy’s home charging page says installations must meet state and local codes and recommends having an electrician confirm your home has enough capacity for Level 2 charging. This guide covers what the electrical code requires, where cities draw the permit line, and what to have ready. If you don’t know which office covers your address, you can find your local building department.

What the electrical code requires

EV charging equipment is covered by Article 625 of the National Electrical Code (NFPA 70), which states adopt, sometimes with amendments. California defines an “electric vehicle charging station” in Government Code Section 65850.7 as equipment built to comply with Article 625 of the California Electrical Code. Palatine, Ill., requires residential charger installations to conform with the 2020 NEC, Article 625 Part III.

Local handouts that summarize Article 625 for homeowners repeat the same core rules:

• Its own circuit. Each EV outlet must be supplied by an individual branch circuit with no other outlets. Wildomar, Calif., cites sections 625.40 and 625.41 of its state electrical code for this.
• Sized for continuous load. Charging is a continuous load, so the circuit and its breaker must be rated at no less than 125 percent of the charger’s maximum load. A charger that draws 40 amps continuously therefore needs at least a 50-amp circuit. Palatine says all three levels of charging carry this 125 percent requirement.
• A lockable disconnect for large units. Wildomar’s handout (citing 625.43) requires a readily accessible disconnect that can be locked open when the equipment is rated above 60 amps.
• Listed equipment. San Diego, Seattle, and Santa Clarita, Calif., all require chargers to be listed by a nationally recognized testing laboratory such as UL.
• GFCI protection for receptacles. Santa Clarita requires ground-fault protection for a charger receptacle, citing section 210.8(A) of the 2022 California Electrical Code.
• Storage height and protection. Wildomar requires the connector to be stored at least 18 inches above the floor indoors and 24 inches above grade outdoors (citing 625.50). It also requires guards where a car could hit the unit, unless the unit is mounted on a side wall out of the vehicle’s path.

Section numbers in Article 625 have moved between NEC editions, and some local handouts cite different numbers for the same rule. Ask your department which edition it enforces.

When you usually need a permit

Expect to need an electrical permit for any of these:

• A Level 2 charger hardwired to a new 240-volt circuit.
• A new 240-volt receptacle, such as a NEMA 14-50, installed for plug-in charging.
• A new 120-volt receptacle added for a Level 1 charger. Wildomar requires a permit for this, though it doesn’t require plans or load calculations.
• Running a circuit to a detached garage, carport, or driveway pedestal, especially if it involves trenching.
• A panel replacement, subpanel, or service upgrade needed to carry the charger. Santa Clarita requires an electrical permit for new or upgraded panels and lets you combine it with the charger permit.

Work that is often exempt

• Plugging into an outlet you already have. Wildomar says no permit is needed for a Level 1 charger on an existing receptacle. Prince William County, Va., goes further: no permit is needed for any cord-and-plug charger connected to an existing circuit that meets the manufacturer’s installation instructions.
• Swapping a plug-in charger on an existing, properly sized receptacle, under the same logic.

These exemptions are local. Seattle’s guidance states that electrical permits are required for all electric vehicle charger installations.

Load calculations and service capacity

A Level 2 charger can be the largest continuous load in a house, so most departments want proof that your existing service can handle it.

• When it is required. Santa Clarita requires a residential load calculation under Article 220 only when the service is smaller than 200 amps. It recommends one for larger services. Prince William County requires a load calculation worksheet for any charger over 20 amps and counts the charger at 125 percent of its nameplate rating. San Diego requires the load calculation on its residential Circuit Card.
• How it is done. Wildomar’s worksheet, based on section 220.83(A) of the California Electrical Code, adds up the house’s general loads. It counts the first 10,000 watts at 100 percent and the remainder at 40 percent, then compares the total to the main breaker size. On that table, a total up to 24,000 watts fits a 100-amp service and 36,001 to 48,000 watts calls for 200 amps. If your service is smaller than the table requires, you need a bigger service.
• Who does it. Santa Clarita requires the calculation to be done by a qualified professional, meaning a licensed electrical contractor or engineer.

If the calculation fails, you have two options: upgrade the service, or ask your department whether it accepts a lower-amperage charger or a listed load-management device. A service upgrade also involves the utility. Seattle tells homeowners to contact Seattle City Light before starting if their electrician finds the service isn’t adequate.

How the rules differ by city

• San Diego, Calif. Chargers in a residential private garage at a single dwelling, duplex, or townhouse qualify for a “Simple No Plan” permit through the online portal. Instead of plans, you submit a Circuit Card (DS-1779A) that includes the load calculation and keep it on site for the inspector. Information Bulletin 187 (May 2026) lists an inspection fee of $264.25 per charger for these homes. Properties in historic districts or designated historic resources don’t qualify for the simple permit.
• Seattle, Wash. SDCI Tip 132 (updated July 25, 2022) says a single-family electrical permit for a 40-amp Level II charger needs no plan review and can be bought online. A homeowner may do their own installation and pull the permit. SDCI’s electrical permit page says owners can do their own work only on property they own and occupy. SDCI notes that some of its Tips may not reflect the most current rules, so confirm before applying.
• Prince William County, Va. Under Policy 3.3.1, a permit is required when a circuit or feeder is added or extended, or when the charger is hardwired. Plans are reviewed as a walk-through review with no plan review filing fee. You’ll need the manufacturer’s installation instructions, plus a load calculation for chargers over 20 amps, and both must be shown to the inspector.
• Los Angeles, Calif. The Department of Building and Safety (LADBS) added EV chargers to the work it will issue as an Express Permit, with no plan review. According to the Los Angeles Department of Water and Power (LADWP), inspection requests can typically be scheduled for the next business day. A separate time-of-use meter takes about 5 to 10 business days after LADBS approval if no panel upgrade is needed.
• Santa Clarita, Calif. The city’s checklist (revised May 16, 2024) offers counter review for residential chargers. It requires a load calculation only for services under 200 amps and usually needs one inspection, plus a rough inspection if wiring will be concealed in a wall. Outdoor chargers or receptacles need Planning approval before the permit is issued.

California’s streamlining law. Assembly Bill 1236 (2015) added Section 65850.7 to the Government Code. It requires every California city and county to adopt an expedited, streamlined permitting process for charging stations, with a published checklist and electronic submittal. Cities and counties with 200,000 or more residents had to adopt their ordinance by September 30, 2016, and smaller ones by September 30, 2017. Review is limited to health and safety. The state’s GO-Biz office tracks local compliance and notes that AB 970 (2021), codified as Section 65850.71, added binding review timelines.

Utility rebates. Some utilities pay part of the cost. Austin Energy offers 50 percent of the cost, up to $500, for a qualifying Level 2 home charger. To get it, you must enroll the charger in its Power Partner EV program and use equipment listed by UL, ETL, or cETL. Austin Energy states that proper permitting and inspection are the customer’s and installer’s responsibility.

What the inspection covers

Inspectors check that the circuit, breaker, and wire are sized for the charger’s rating. They also look at the mounting location, any required disconnect, receptacle GFCI protection, and that the panel isn’t overloaded. Expect these requirements:

• San Diego and Santa Clarita require the manufacturer’s installation instructions on site at inspection.
• Prince William County requires the approved load calculation worksheet on site.
• Seattle’s electrical permits generally require cover, service, and final inspections, each scheduled separately.
• In Los Angeles, a job that includes a panel upgrade or a separate meter also needs an LADWP inspection.

What to have ready

• Charger make, model, voltage, and maximum current (Santa Clarita asks for these on the application), plus the spec sheet for hardwired units.
• The manufacturer’s installation instructions.
• A load calculation, or your city’s worksheet, showing the existing service can carry the charger at 125 percent.
• Breaker size, wire size, and conduit or cable type and route from the panel to the charger. Palatine asks for these on the drawings.
• The charger location, with distance from the panel, and a site plan if the unit is outdoors or in a detached structure.
• Contractor license information, or an owner-builder form if you’re doing the work yourself. San Diego uses Form DS-3042 and Prince William County uses a Statement of Exemption.
• Your utility’s application, if a service upgrade or separate meter is involved.

Doing it yourself

Many jurisdictions let owner-occupants pull their own electrical permit. Seattle and Prince William County both allow it. Others restrict electrical work to licensed contractors, and rebate programs may set their own rules. See our guides to owner-builder permits and electrical permits. If you’re also adding solar or a home battery, the solar panels guide covers how those permits interact.

Questions to ask your building department

• Does plugging into an existing outlet need a permit here, or does every charger installation?
• Is there an express, online, or no-plan permit for a single-family Level 2 charger?
• At what service size do you require a load calculation, and do you have a worksheet?
• Do you accept a load-management device instead of a service upgrade?
• Which NEC edition do you enforce?
• Does an outdoor charger need zoning or planning approval?
• How many inspections are required, and what must be on site for them?
