The top electrical, communications, fire alarm, and security related companies in North Carolina
Short answer: Exchange lists 8 electrical contractors in North Carolina. Every electrical contracting business in the state needs a license from the North Carolina State Board of Examiners of Electrical Contractors, issued in a classification that caps project size: limited licensees can take projects up to $60,000, intermediate up to $150,000, and only unlimited licensees can go above that. The 2020 North Carolina Electrical Code, based on the 2020 NEC, remains in force because adoption of the 2023 edition has been delayed indefinitely.

Code in force
The 2020 North Carolina State Electrical Code, effective November 1, 2021, is still current; the 2023 edition is on indefinite delay.
Lien deadline
A claim of lien on real property must be filed with the county clerk of superior court within 120 days of the last furnishing of labor or materials.
Lien agent notice
On most projects of $40,000 or more, subcontractors must notify the designated lien agent within 15 days of first furnishing to protect lien priority.
Who licenses electrical contractors in North Carolina?
In North Carolina, electrical contractors are licensed by the State Board of Examiners of Electrical Contractors under Article 4 of Chapter 87 of the General Statutes, and the license is held by the business rather than an individual worker.
G.S. 87-43 says no one may engage, or offer to engage, in electrical contracting without a license in the right classification, and each separate place of business must list at least one qualified individual who is regularly on active duty there and has authority to supervise all electrical work from that location. The Board issues three regular classifications (limited, intermediate and unlimited), a special restricted single-family detached dwelling license (SP-SFD), and six special restricted licenses for narrow scopes: fire alarm and low voltage (SP-FA/LV), elevator (SP-EL), plumbing, heating and air conditioning (SP-PH), groundwater pump (SP-WP), electric sign (SP-ES) and swimming pool bonding (SP-SP). Board rules also require all business, advertising and paperwork to be conducted in the exact name on the license, so the company name on a proposal should match the Board record word for word.
Licenses run for one year. Annual fees under 21 NCAC 18B .0404 are $100 for limited, SP-SFD and special restricted licenses, $150 for intermediate and $200 for unlimited. Renewals filed after the expiration date carry a $25 administrative fee, and every listed qualified individual on a limited, intermediate, unlimited or SP-SFD license must complete eight hours of Board-approved continuing education before each annual renewal. Under 21 NCAC 18B .0407, every license number carries a suffix showing its classification (L, I, U, SP-SFD or SP plus a scope code), so the class can be read straight off a permit, a truck door or a bid form and checked against the Board's online license search.
How do you qualify for a North Carolina electrical contractor license?
To qualify in North Carolina, an individual must be at least 18, document enough electrical experience for the classification sought, pass the Board qualifying exam with a score of 70 or higher, and then be listed on a licensed business.
Under 21 NCAC 18B .0201, exam applicants need 3,000 hours of experience for the limited classification (2,000 of them primary experience), 5,750 hours for intermediate (5,000 primary) and 9,000 hours for unlimited (8,000 primary). The SP-SFD and SP-FA/LV classifications also start at 3,000 hours. Primary experience means hands-on installation of wiring governed by the National Electrical Code; journeyman electricians, foremen, superintendents, estimators for licensed contractors and state-recognized electrical inspectors all earn full credit. Unlimited applicants must also supply two statements from people familiar with their work attesting that they can supervise an unlimited-classification business. Each applicant files two character references, and the exam fee is $125 for every classification.
Passing the exam qualifies the person, not a company. The business then applies for the license, pays the annual fee and names its qualified individual. Intermediate and unlimited applicants must also file a bonding ability statement or a bank line of credit letter under G.S. 87-43.2. The Board's licensing page sets the bonding ability thresholds at more than $50,000 for intermediate and more than $130,000 for unlimited. New qualifiers must complete a free four-hour Laws and Rules course run by Board staff within 12 months of becoming a qualified individual. A candidate who fails must wait three months before retesting in the same classification.

How do I check an electrical contractor in North Carolina before I sign?
7 checks, in order, using the North Carolina registers and rules described on this page:
Look up the company in the NC Board of Examiners of Electrical Contractors online license search and confirm the license is active and the name matches the contract exactly.
Check the license suffix (L, I, U, SP-SFD or SP) against your job value: limited is capped at $60,000 and intermediate at $150,000, including equipment you buy yourself.
On a detached single-family home, an SP-SFD license is enough; for a townhouse, commercial space or outbuilding serving a business, require a limited, intermediate or unlimited license.
Write into the contract that the electrical contractor will pull the permit from your local inspections department under G.S. 160D-1110 and request final inspection within 10 days of completion.
For work of $40,000 or more that is not on your own existing home, designate a lien agent and make sure the permit lists the lien agent details.
After a hurricane or storm, refuse cash-only or large upfront deposit demands from door-to-door crews, as the Board warned after Hurricane Helene, and pay against completed, inspected work.
Ask which edition the design follows; North Carolina still enforces the 2020 State Electrical Code, so plans citing the 2023 NEC may include requirements inspectors will not yet enforce.
What project value can each North Carolina electrical license class take on?
North Carolina caps electrical project size by license class: limited licensees may take projects up to $60,000, intermediate licensees up to $150,000, and unlimited licensees have no dollar cap under 21 NCAC 18B .0303.
The statute behind the caps, G.S. 87-43.3, lets the Board set limits by rule but no higher than $100,000 for limited and $200,000 for intermediate, and the Board may revisit them no more than once every three years based on a project cost index. The Board's rule counts the total cost of all wiring, materials, equipment, fixtures, devices and installation, including anything an owner or general contractor furnishes, so an owner who buys the switchgear does not shrink the project value. If a single project is split into several contracts, the combined value awarded to one licensee still has to fit within that licensee's cap. A separate project generally needs its own service or feeder, its own permit and separate bidding, and all work covered by one set of plans is treated as one project. The cap does not apply to special restricted licenses: an SP-FA/LV or SP-SP holder may take any size job within its narrow scope.
Which electrical code and permits apply in North Carolina?
North Carolina enforces the 2020 State Electrical Code, the 2020 NEC with state amendments, effective November 1, 2021; the 2023 edition was originally set for January 1, 2025 but is on indefinite delay.
The Office of State Fire Marshal lists the 2023 State Electrical Code as delayed under Session Law 2025-2. Section 5.12 of that law pushes the 2024 North Carolina State Building Code back until 12 months after the first day of the month following the State Fire Marshal's certification that the Building Code Council and Residential Code Council have finished publishing and distributing the code. Until that certification happens, contractors should price and install to the 2020 code and its state amendment packages, and watch the Fire Marshal's code page for the certification date.
Permits come from the local code enforcement office. G.S. 160D-1110 requires a permit for the installation, extension, alteration or general repair of any electrical wiring, devices, appliances or equipment. In one- and two-family dwellings, repair or like-for-like replacement of lighting fixtures, receptacles and switches of the same voltage and equal or lower amperage needs no permit, and a licensed electrical contractor may connect a replacement electric water heater of the same or lower rating in the same location without one. Board rule 21 NCAC 18B .0909 makes the licensee responsible for pulling the permit before work begins and requesting final inspection within 10 days of completion. Lending a license number for a permit on work the licensee is not supervising is treated as misconduct.
What are the lien and payment deadlines for electrical contractors in North Carolina?
In North Carolina, an electrical contractor must file a claim of lien on real property within 120 days after last furnishing labor or materials, and must start an enforcement action within 180 days of that last furnishing.
The claim is filed with the clerk of superior court in each county where the property sits (G.S. 44A-12), and the 180-day enforcement deadline comes from G.S. 44A-13. Priority depends on the lien agent system. Under G.S. 44A-11.1, an owner must designate a lien agent when the improvement costs $40,000 or more, unless the work is on an existing owner-occupied single-family home or an accessory structure for it. G.S. 160D-1110 also requires the lien agent's details to appear on building permits for work of $40,000 or more. Under G.S. 44A-11.2, a subcontractor that wants full lien rights against later mortgages and buyers should get its Notice to Lien Agent received no later than 15 days after first furnishing. A sub that misses that window can still serve a notice, but only before a sale or a mortgage is recorded. A notice to lien agent lasts five years and can be renewed once.
Prompt payment rules in Chapter 22C also apply to private jobs. G.S. 22C-3 requires a contractor or subcontractor to pay its own subcontractor within seven days of receiving each periodic or final payment, provided the sub has performed. G.S. 22C-2 makes pay-when-paid clauses between subcontractors unenforceable when they make payment to one sub depend on payment to another. On public buildings, G.S. 143-128 lists electrical wiring and installations as a separate subdivision of work, so electrical contractors often bid public jobs directly as separate primes or are named in single-prime bids.
How is data center and energy demand changing electrical work in North Carolina?
North Carolina is drawing large data center and AI investments, led by a $10 billion Amazon cloud and AI campus announced in June 2025 for Richmond County, which increases demand for unlimited-class electrical contractors.
Governor Josh Stein's office announced the Amazon project on June 4, 2025, saying it would create at least 500 high-tech jobs at the Energy Way Industrial Park in Richmond County and calling it among the largest investments in state history. The release named the availability of skilled labor as one reason North Carolina was chosen. Projects like this need medium-voltage distribution, generators and switchgear, uninterruptible power supply rooms, and extensive low-voltage and fire alarm cabling. The electrical scope on a single data hall is far above the $150,000 intermediate cap, so the prime electrical contractor must hold an unlimited license, while fire alarm and structured cabling subcontractors can work under an SP-FA/LV license that has no project value cap.
Because the North Carolina value cap includes owner-furnished equipment, owners buying long-lead transformers and switchboards directly should expect the full equipment value to count toward the electrical contractor's project limit. The same rule matters on commercial solar, battery storage and EV charging work across the state, where equipment is a large share of project cost and can push a seemingly small installation over the $60,000 limited-license threshold. Under 21 NCAC 18B .0801, a limited, intermediate or unlimited licensee may also perform work within any special restricted scope, so one regular licensee can carry the power, storage and low-voltage scope together, as long as its classification covers the total project value.
What does a North Carolina fire alarm or low voltage contractor need?
In North Carolina, fire alarm, burglar alarm and most low-voltage wiring must be installed by a contractor holding at least the special restricted SP-FA/LV license or a regular limited, intermediate or unlimited license.
21 NCAC 18B .0804 defines the SP-FA/LV scope as systems of 50 volts or less, Class II and Class III power-limited circuits, paging systems up to 70 volts, fire alarm systems wired to a common control panel under the State Building Code and NFPA 72, and burglar alarm systems. The license also covers line-voltage wiring up to 300 volts to ground, but only from the load side of a disconnect or junction box that someone else installed and labeled for that system. Applicants need 3,000 hours of experience, and qualifiers complete four hours of continuing education each year instead of eight.
Some low-voltage work needs no license at all. Under 21 NCAC 18B .0805, an unlicensed installer may wire a low-voltage system only if it is not required by the State Building Code, is a Class II or III system at 50 volts or less, is not in a hazardous location, is current limited, and would not create a shock or fire hazard in the inspector's opinion. Fire and burglar alarm systems never qualify for that exemption. Owners hiring a security or audiovisual integrator should confirm which side of that line the job falls on before work starts.
How are North Carolina homeowners protected when hiring an electrician?
North Carolina homeowners are protected by the license requirement, the permit and inspection system, and the Board's public license search, and the Board has specifically warned residents about storm-repair scams since Hurricane Helene.
After Hurricane Helene in 2024, the Board warned western North Carolina residents about door-to-door repair offers and demands for cash or large upfront deposits. It also granted a year of continuing education credit to active qualifiers in declared disaster counties. Storm work is where unlicensed operators are most common, so homeowners should check the license number and classification in the Board's online search before paying anything. The SP-SFD license covers only wiring in or on a detached single-family home and its ancillary structures, such as a detached garage, barn or pump house, so an SP-SFD holder cannot take a commercial job or wire a townhouse building.
G.S. 87-43.1 lets an owner do electrical work on their own property for their own benefit, but only when the property is not intended at the time for rent, lease or sale. Cord-and-plug appliance installation, replacing lamps and fuses, and servicing equipment from an existing junction box need no license, but installing the receptacle or junction box itself does. Because Board rules require the licensee to pull the permit and request final inspection, a contractor who suggests skipping the permit or asks the owner to pull a homeowner permit for contractor work is a warning sign.
Where can I verify a license and check the source in North Carolina?
Every figure and rule on this page can be checked against the primary source. These are the offices that publish them. Confirm current requirements directly before you rely on any of them:
Is a general contractor license enough to do electrical work in North Carolina?
No. Electrical contracting is licensed separately by the State Board of Examiners of Electrical Contractors under G.S. 87-43. A general contractor without an electrical license must subcontract the wiring to a licensed electrical contractor, whose license classification must cover the full value of the electrical project, including equipment the owner or general contractor supplies.
Can I wire my own house in North Carolina?
Yes, if the work is on your own property, for your own benefit, and the property is not intended at the time for rent, lease or sale, under G.S. 87-43.1. A permit and inspection are still required for most wiring work under G.S. 160D-1110. If you plan to sell or rent the home, hire a licensed electrical contractor instead.
Does replacing a light fixture need a permit in North Carolina?
Not in a one- or two-family dwelling. G.S. 160D-1110 exempts repair or replacement of lighting fixtures and devices such as receptacles and switches when the replacement has the same voltage and the same or lower amperage. New circuits, service changes, additions and most other alterations still need a permit from the local inspections department.
When will North Carolina adopt the 2023 NEC?
No firm date is set. The Office of State Fire Marshal lists the 2023 State Electrical Code as on indefinite delay under Session Law 2025-2. The 2024 code collection takes effect 12 months after the first day of the month following the Fire Marshal's certification that publication and distribution are complete.
How long does a subcontractor have to send a Notice to Lien Agent in North Carolina?
To keep full lien priority, the notice should be received by the lien agent no later than 15 days after the subcontractor first furnishes labor or materials, under G.S. 44A-11.2. A later notice still works if it is received before a sale to a buyer or before a mortgage or deed of trust is recorded.
What exam score is needed for a North Carolina electrical license?
Board rule 21 NCAC 18B .0204 requires a minimum score of 70 out of 100 on any qualifying exam. Eligibility notices are valid for three months and one exam sitting, and a candidate who fails must wait three months before retesting in the same classification. The application and exam fee is $125.
Do solar and battery installers need an electrical license in North Carolina?
Yes. Installing PV systems, inverters, battery storage and the wiring connecting them to a building is electrical contracting under G.S. 87-43, so the installer needs a Board license in the right classification. Because equipment cost counts toward the project value, larger commercial arrays often need an intermediate or unlimited license.
