EV charger and heat pump permits in North Carolina: do you need one, who can install it, and what it costs

Yes: in North Carolina a home EV charger and a heat pump both need a permit, whatever they cost. A Level 2 charger means a new 240-volt circuit, which is electrical work the $40,000 exemption doesn't cover, and installing or replacing heating and air-conditioning equipment always needs a mechanical permit. Both are licensed trades, though a homeowner may do the work on a home they own and live in. This guide covers what each permit requires, the code rules installers follow, and what over 8,000 permits filed in the last 12 months show about the jobs: the circuit sizes, the declared costs and how quickly offices issue them.

EV chargers: the permit, the license and the code

• The permit. A Level 2 charger needs an electrical permit from your city or county inspections office, because it adds a circuit (G.S. 160D-1110(c)). Many offices, including Mecklenburg, Wake County and Gaston County, file it as a residential electrical or trade permit.
• The license. The work is electrical contracting: a licensed electrical contractor pulls the permit, or the homeowner does under the owner exemption. Charger makers' certified-installer programs don't replace the state license.
• The code. North Carolina's electrical code is the 2020 National Electrical Code with state amendments, in effect since November 1, 2021; the 2023 edition's start has been postponed. Article 625 gives each charger its own branch circuit and treats charging as a continuous load, so the breaker must be rated at least 125% of what the charger draws: a charger set to 48 amps goes on a 60-amp breaker, and one set to 40 amps on a 50-amp breaker.
• The panel. The house's electrical service has to be able to carry the new load. If it can't, the job grows into a panel or service upgrade, or a load-management device that holds the charger back when the house is drawing a lot.

EV charger permits by office

Mecklenburg County files more charger permits than every other office combined. The declared job cost is strikingly consistent wherever offices record it, and most offices issue the permit within a few days.

What the charger permits describe

• Circuit size. About a third of permits state one. Of those, 51% name a 60-amp circuit, 30% a 50-amp, 8% a 40-amp and 4% something larger: most new chargers are set up for 48 amps or a little less.
• The charger. 17% mention a Tesla Wall Connector or Tesla charger by name. More descriptions mention a receptacle or plug (often a NEMA 14-50 outlet for a plug-in charger) than a hardwired unit, 332 to 201.
• The panel. About 4% of charger permits also mention a panel change, a subpanel or a service upgrade in the same permit, and a handful a load-management device.
• The installers. 758 companies were named on charger permits; 57% of them did only one in the year, and the ten busiest did 29% of the work. Charger installs are mostly a sideline for general electricians, not a specialty.

Heat pumps and mini-splits: the permit, the license and the refrigerant

• The permit. Installing or replacing a heat pump, air handler or mini-split needs a mechanical permit at any cost, including a like-for-like change-out (G.S. 160D-1110). A new circuit or a bigger breaker for the system is electrical work as well.
• The license. A home system of 15 tons or less is "heating, group number three" work under G.S. 87-21, licensed by the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors; anyone paid to install it needs that license, at any job size. A homeowner may install their own on a home they own and live in.
• The wiring. An HVAC contractor with the special restricted SP-PH electrical license may wire their own equipment, starting at the load side of a breaker or disconnect that someone else installs (21 NCAC 18B .0807). Otherwise a licensed electrician does the electrical part.
• The refrigerant. Since January 1, 2025, new home AC and heat pump equipment must use lower-GWP refrigerants such as R-454B, one of the mildly flammable A2L refrigerants; A2L equipment was about 90% of the market by late 2025, according to an industry figure cited by EPA. EPA's May 2026 rule lets R-410A equipment made or imported before 2025 still be installed, and a failed R-410A outdoor unit can be replaced on an existing system; replacing the indoor coil too makes it a new system that must use the new refrigerants.

Heat pump permits by office

Five offices describe the equipment on their mechanical permits closely enough to count heat pumps. Together they filed 4,941 heat pump and mini-split permits in the last 12 months, and 73% were replacements: a change-out, often written "like for like". New homes account for very few, because the heat pump in a new house is usually part of the builder's permit rather than a separate one.

Of the heat pump permits that give a size, the median system is 2.5 tons: 53% are 2 to 2.9 tons, 27% are 3 to 3.9, 10% are 4 or 5 and 9% are under 2. Wake County is the one office that records a job value on nearly every permit, and there the median heat pump job was $11,000, with the middle half between about $7,800 and $15,200. Fewer than 1% of descriptions say the job converts a home from gas or oil; most heat pumps in North Carolina replace heat pumps.

What it means for homeowners and installers

• Homeowners: ask whether the quote includes the permit. Both permits are usually issued within a few days, so a permit rarely delays a charger or a heat pump replacement, and the inspection is your check that a 60-amp circuit or a refrigerant line was done right.
• Electricians: chargers are steady, small jobs spread across hundreds of companies. Panel upgrades and load-management devices are the larger tickets that ride along with them.
• HVAC contractors: replacement work dominates, and R-410A stock can now be installed without a deadline, but new equipment, and any job that replaces both the outdoor unit and the indoor coil, means the newer refrigerants.
• Both: the federal tax credits for heat pumps and home chargers have ended, and the permits kept growing anyway; our article on the end of the credits has the month-by-month numbers.

How the numbers were counted

Permits filed (or issued, where an office records only that date) in the 12 months to October 23, 2026, in the offices TarSignal reads, found by their permit type and description: "EV charger", "electric vehicle", "EVSE", "car charger", "Tesla wall connector" and similar for chargers, and "heat pump", "mini-split" and "ductless" for heat pumps. Withdrawn, voided and cancelled permits are left out. Heat pumps are counted only in the five offices whose mechanical permits name the equipment; Mecklenburg, Cabarrus, Union and Johnston file trade work without it. A declared cost is what the applicant wrote on the permit, not an invoice, and it's shown only where an office records it on most permits. Days to permit are counted from the application date to the issue date, where an office records both; Greensboro is left out because its permits are entered after plan review. Codes and rules are as published by the State Fire Marshal, the General Assembly and EPA in October 2026.
