A homeowner's guide to electrical work in the Triangle

This guide covers what panel upgrades, EV chargers, new circuits and rewiring cost around Raleigh, Durham, Cary and Chapel Hill, which North Carolina electrical license the work needs, and what each town's permit costs. It also explains why Duke Energy waits for a passed inspection before it sets your meter, which code your house is inspected under, and how to check an electrician before you sign.

What electrical work costs in the Triangle

These are guide figures from cost websites, not quotes. The first four rows are for Raleigh; the rest are not specific to North Carolina. Angi says it applies local price index data to calculate its city estimates (Angi, Raleigh panels), so treat even the Raleigh rows as estimates. Get written quotes for your own job.

What moves the price

• Whether the panel itself must change. HomeGuide's 200-amp upgrade figure rises when a new service panel is required (HomeGuide, panels).
• What an EV charger asks of your panel. HomeGuide says a charger costs more when the panel needs work or the wire run is long (HomeGuide, EV chargers). Raleigh notes that typical 240-volt chargers need 40-amp service, and that this load may require a bigger main service or breaker panel (Raleigh, EV chargers).
• The age of the wiring. Replacing knob-and-tube wiring often means a new panel as well (HomeGuide, knob and tube).
• Permit and inspection fees. They differ by town, and the permits section below lists them.

Tax credits and rebates, as of October 2026

• The federal credit for a home EV charger paid 30% of the cost, up to $1,000 per charging port at your main home, for property placed in service from January 1, 2023, to June 30, 2026 (IRS, charger credit). A charger installed now does not qualify (IRS, charger credit).
• The federal Energy Efficient Home Improvement Credit paid up to $600 toward a panel of 200 amps or more, when the panel was needed to support qualifying energy equipment such as a heat pump (IRS, home improvement credit). It covers only improvements made through December 31, 2025 (IRS, home improvement credit).
• Duke Energy's EV Charger Prep Credit page is still up. It covers wiring, conduit, outlets, panel upgrades and breakers for a charger, but not the charger itself, mounting or permit fees (Duke Energy, Charger Prep Credit). If you have already chosen a contractor, or finished the prep work in the last four months, you can send Duke the paid invoice and get a check (Duke Energy, Charger Prep Credit). The page gives no dollar amount (Duke Energy, Charger Prep Credit). Duke's launch announcement of September 26, 2022 said up to $1,133 per household (Duke Energy, 2022 launch), so ask Duke what the credit pays now.
• Energy Saver North Carolina, a federal rebate program run by the NC Department of Environmental Quality, pays up to $4,000 toward an electrical panel for households at or below 150% of area median income (Energy Saver NC). It covers up to 100% of the cost below 80% of area median income and up to 50% from 80% to 150% (Energy Saver NC). It opened in Durham, Orange and Chatham counties in December 2025 and in Wake County in January 2026 (Energy Saver NC).

Licenses: who may do this work in North Carolina

No person or company may do electrical contracting in North Carolina, or offer to, without a license in the right class from the State Board of Examiners of Electrical Contractors (G.S. 87, Art. 4). There is no dollar minimum, so even a small job needs one (G.S. 87, Art. 4). You may read that a license is needed only for jobs of $40,000 or more. That threshold is the general contractor rule (G.S. 87-1), and it does not apply to electrical work (G.S. 87, Art. 4).

License classes

• Limited (L) covers a single project worth up to $60,000 (NC electrical board).
• Intermediate covers projects up to $150,000 (NC electrical board).
• Unlimited covers projects of any value (NC electrical board).
• Single-family detached (SP-SFD) is a separate license for contractors who only wire detached houses, with the same per-project cap as the limited license (G.S. 87, Art. 4).
• Special restricted classes cover narrow trades. The SP-PH license held by plumbing, heating and air conditioning companies lets them wire only as an incident to their own business, so it does not cover a panel upgrade or an EV charger circuit (21 NCAC 18B). Six other special restricted classes cover narrow trades such as fire alarms, signs and elevators (NC electrical board).

State law lets the Board raise the dollar limits, to as much as $100,000 for a limited license and $200,000 for an intermediate one (G.S. 87, Art. 4). The figures in the list are the ones the Board's licensing page shows (NC electrical board).

How to check a license

The Board's free Verify License Search looks up a license by number, company name, person's name, phone or address; you fill in at least one field (NC electrical board search). The NC Attorney General's office also tells homeowners to check an electrician's license with the Board online or by phone (NC Attorney General, archived copy).

Doing the work yourself

State law lets you do electrical work on your own property for your own benefit, as long as the property is not meant for rent, lease or sale at the time (G.S. 87, Art. 4). Each town handles this its own way.

• Raleigh asks for a notarized Owner Exemption Affidavit. On it you swear to live in the home for 12 months after the work, when it may not be offered for rent, lease or sale, and to be there for every inspection (Raleigh owner affidavit).
• Durham lets an owner pull an electrical permit only for a single-family primary residence with the owner's name on the deed, after filing a Homeowner Acting as Their Own Contractor form (Durham homeowner form). The form is good for one year (Durham permit rules). On it the owner also initials that the property will not be "rented, leased, or sold for 1 year" (Durham homeowner form). You must do the work yourself; the form says you cannot hire or allow someone else to do it (Durham homeowner form).
• Cary says an owner may do their own electrical work without a license if the home stays their primary residence for at least 12 months afterward (Cary permit FAQ).
• Chapel Hill: this guide did not find whether a homeowner may pull their own electrical permit, or on what form. Ask the town's permit office.

Durham reads state law to mean a like-for-like swap of a fixture, outlet or switch skips the permit only when a licensed contractor does it (Durham permit rules). Ask your permit office before swapping one yourself.

What unlicensed work risks

Doing or offering electrical work for pay without a license is a Class 2 misdemeanor, and the Board can also get a court order stopping the work, plus up to $5,000 in attorney's fees (G.S. 87, Art. 4). Raleigh lists what can follow work done without a permit: citations, higher fees, having to remove the work, trouble selling the house, and gaps in insurance (Raleigh residential permits). Its page warns that homeowner's insurance may not cover problems caused by work done without a permit (Raleigh residential permits).

Permits in Raleigh, Durham, Cary and Chapel Hill

North Carolina requires a permit before anyone installs, extends, alters or makes a general repair to electrical wiring, devices, appliances or equipment (G.S. 160D-1110). The state's permit exemption for work costing $40,000 or less does not reach electrical work beyond like-kind replacement of devices and lighting fixtures, so new circuits, panels, EV chargers and generator hookups still need a permit (G.S. 160D-1110). Where the law requires a licensed contractor, a town may issue the permit only if a licensed contractor will do the work, which is why the permit should be in your electrician's name (G.S. 160D-1110).

Raleigh

• Raleigh requires a permit for an electrical service upgrade, added circuits or outlets, interior vehicle charging stations, and switches and lights (Raleigh residential permits).
• A new or replacement standby generator needs an Electrical Generator permit through the city's Permit and Development Portal, with a plot plan or survey (Raleigh residential permits).
• A home EV charger needs a permit before any work starts and a city inspection (Raleigh, EV chargers). The residential submittal is the Residential Permit Application, a survey showing the work, and power riser information and cut sheets for the charger (Raleigh, EV chargers). If the charger needs a service or panel upgrade, that can be done at the same time (Raleigh, EV chargers).
• Raleigh's FY27 fee guide sets the minimum trade permit fee at $124 per trade ($129 with the City's 4% technology surcharge), up from $123, and charges it for any fee not listed separately (Raleigh fee guide FY27). A re-inspection costs $122 per inspection per trade ($127 with the surcharge) (Raleigh fee guide FY27).

Durham (city and county)

• Durham requires an electrical permit for any installation, extension, alteration or general repair, except like-for-like swaps of fixtures, outlets and switches by a licensed contractor (Durham permit rules).
• When a contractor is new to Durham, staff check that the license is active and that the name on it matches the name on the permit application (Durham permit rules).
• Inspections are booked through the online portal and scheduled for the next business day (Durham permit rules).
• Durham's posted electrical fee schedule is dated July 1, 2018 (Durham fee schedule). It prices service equipment by its amp rating: $34.00 up to 100 amps, plus $6.97 for each additional 100 amps (Durham fee schedule). The same schedule sets a $65.00 minimum electrical permit fee, and $100.00 when a residential permit needs a rough-in inspection (Durham fee schedule).
• Because the schedule dates from 2018, ask Durham what a panel change or EV charger circuit costs today. This guide found no Durham EV charger submittal rules like Raleigh's.

Cary

• Cary lists EV charging stations, new lighting and receptacle outlets, generators, and turning power on, or disconnecting it from a structure or pool being removed, among the jobs that need a permit (Cary permit FAQ).
• Cary processes an online EV charger permit in about two business days from a complete application (Cary EV guide). Inspections follow NEC Article 625: a groundwork inspection if the wire is trenched, a rough-in if wiring will be hidden, and a final (Cary EV guide).
• Cary's FY2027 fee schedule charges residential electrical permits $0.15 per square foot with a $125 minimum, $125 per re-inspection, and double fees for work started without a permit (Cary fees FY2027).
• The two Cary sources disagree on the minimum. Cary's EV guide, dated 9/25, still shows a $100 minimum per trade (Cary EV guide). The fee schedule is the newer document, but confirm with Cary which figure applies to your job.

Chapel Hill

• Chapel Hill requires a town permit and a town inspection for electrical work (Chapel Hill permits). An electrical-only job uses the Sub/Trade permit application (Chapel Hill permits).
• The residential electrical fee is $115 per panel, whatever its size, plus $100 per "read in/read out" inspection (not defined; ask the town) (Chapel Hill fees).
• A failed residential inspection costs $60 for each of the first two, and the fee doubles after that (Chapel Hill fees).
• Starting work before getting a permit brings a stop-work order and doubled fees (Chapel Hill fees).
• Orange County adds an 8% recyclable materials fee to all permit fees (Chapel Hill fees).
• This guide found no Chapel Hill EV charger submittal rules.

Triangle conditions that matter

This section covers the power company's rules at the meter, the code your house is inspected under, older wiring and panels, and generators.

Duke Energy and your meter

• If Duke Energy supplies your power, it will not connect service or set a meter until your local inspection office tells Duke the work has passed inspection (Duke Energy service manual).
• For a service upgrade or a large new load such as an EV charger, Duke asks you to update your service application by contacting it as early in planning as possible (Duke Energy service manual).
• If the work means moving service equipment, arrange it with Duke in advance; Duke reconnects once your work has passed inspection, and you may owe a contribution-in-aid-of-construction (CIAC) charge (Duke Energy service manual).
• A licensed electrical contractor must tell Duke before breaking the meter seal and again right after the work, so Duke can re-inspect and reseal (Duke Energy service manual).
• This guide did not find what Duke charges to disconnect and reconnect a house during a panel upgrade, or how long the reconnect takes after inspection.

Which electrical code applies to houses

The 2023 North Carolina Electrical Code has been delayed indefinitely by Session Law 2025-2, so it is not in force (NC Fire Marshal, electrical code). The current 2020 NC Electrical Code excludes one- and two-family houses (NC Fire Marshal, 2021 interpretation). Under the State Fire Marshal's interpretation dated November 1, 2021, houses, and townhouses up to three stories, follow the 2017 NC Electrical Code, which is the 2017 National Electrical Code with North Carolina amendments (NC Fire Marshal, 2021 interpretation). This guide found no newer statement from the Fire Marshal, so ask your permit office which edition it inspects to.

AFCI and GFCI protection

• Under the 2017 NC code, 15- and 20-amp, 120-volt circuits in family rooms, dining rooms, living rooms, bedrooms, closets, hallways and similar rooms need AFCI protection (2017 NC code amendments). The North Carolina list does not name kitchens or laundry areas (2017 NC code amendments).
• When wiring in those rooms is modified, replaced or extended, the circuit must get AFCI protection, unless the extension is 50 feet or less and adds no outlets or devices (2017 NC code amendments).
• GFCI rules mostly apply to new construction and major renovations, so older homes may lack GFCI protection (CPSC, GFCI). The national code added it outdoors in 1973, in bathrooms in 1975, garages in 1978, kitchens in 1987, crawl spaces and unfinished basements in 1990, and at laundry and utility sinks in 2005 (CPSC, GFCI).

Older wiring and panels

• Homes wired, added onto or rewired from 1965 to the mid-1970s may contain aluminum branch wiring (CPSC, aluminum wiring). In a CPSC survey, homes built before 1972 and wired with aluminum were 55 times more likely than copper-wired homes to have at least one outlet connection reach fire hazard conditions (CPSC, aluminum wiring).
• CPSC approves only three permanent repairs for aluminum wiring: rewiring with copper, pigtailing with COPALUM connectors, or AlumiConn connectors (CPSC, aluminum wiring). It does not recommend pigtailing with ordinary twist-on connectors (CPSC, aluminum wiring).
• In 1983 the CPSC closed its investigation of Federal Pacific (FPE) Stab-Lok breakers without making a determination as to their safety (CPSC, FPE breakers). Its testing confirmed the breakers fail certain UL calibration tests, but it said it could not link those failures to a hazard (CPSC, FPE breakers).
• This guide found no CPSC statement either way on Zinsco panels.
• Knob-and-tube wiring, generally found in homes from before 1930, can overheat when covered by insulation (DOE insulation guide). The U.S. Department of Energy says active knob-and-tube wiring should be replaced before an insulation project begins (DOE insulation guide).

Generators

• Never power a house by plugging a generator into a wall outlet, which is called backfeeding (CPSC, generators). CPSC says it puts utility workers and neighbors served by the same transformer at risk of electrocution, and it bypasses some of the home's built-in circuit protection (CPSC, generators).
• A standby generator with an open-transition transfer switch, which breaks one connection before making the other, needs no interconnection agreement with Duke Energy (Duke Energy service manual). A closed-transition setup must apply to Duke and be approved before installation (Duke Energy service manual).

Hiring: questions to ask and red flags

Questions to ask

• What is your license number and class? Look it up in the Board's Verify License Search (NC electrical board search), and check that the class covers the job: a limited license stops at $60,000 per project (NC electrical board).
• Will the permit be in your company's name? When a contractor is new to Durham, staff check that the name on the license matches the name on the permit application (Durham permit rules).
• If my service or meter has to change, will you contact Duke Energy and handle the meter seal? A licensed contractor must notify Duke before breaking the seal and right after the work (Duke Energy service manual).
• For an EV charger: will my panel or service need an upgrade? Raleigh warns that a charger's load may require an upgrade to the main electrical service or the breaker panel (Raleigh, EV chargers).
• Will you put the estimate and contract in writing? Get at least three written estimates (NC Attorney General, archived copy). The contract should spell out all the work, the quality of materials, the total price for labor and materials, any warranties, start and finish dates, and who cleans up (NC Attorney General, archived copy).

Red flags

• A contractor who asks you to take out the permit and arrange inspections yourself. The NC Attorney General's office warns that a home builder who does this may not be licensed (NC Attorney General, archived copy).
• A request for a large payment in advance (NC Attorney General, archived copy).
• A contractor who knocks on your door or leaves a flyer (NC Attorney General, archived copy).
• A heating, air conditioning or plumbing company offering to do a panel upgrade or EV charger circuit on its SP-PH license, which covers wiring only as an incident to its own business (21 NCAC 18B).
• Anyone who suggests powering the house through a wall outlet with a generator (CPSC, generators).

If you sign at home

Under the federal Cooling-Off Rule, a sale of $25 or more made at your home can be canceled until midnight of the third business day after the sale (16 CFR 429). The rule does not cover a visit you asked for to repair or maintain your personal property, though extra goods or services sold during that visit, beyond the repair parts, are still covered (16 CFR 429). If you called the company for a genuine emergency, you can give up the right in a signed, dated statement in your own handwriting (16 CFR 429). Complaints about a home improvement contractor go to the NC Attorney General's office (NC Attorney General, archived copy).
