Yes, you almost always need an electrical permit to install a Level 2 (240V) EV charger in New Hampshire. Permits are issued by your local municipality, not the state. A licensed electrician must perform or supervise the work in most jurisdictions. Level 1 chargers using an existing outlet typically do not require a permit.

Quick Answer: Do You Need a Permit for an EV Charger in New Hampshire?

An electrical permit is required for most EV charger installations in New Hampshire. The specific requirements depend on the charger type.

Level 1 (120V, standard outlet): No permit is needed if you use an existing, code-compliant outlet. If you install a new outlet or circuit, that work requires a permit.

Level 2 (240V, new circuit): An electrical permit is required. This installation involves a new dedicated branch circuit, which triggers permitting under state and local codes.

DCFC / Level 3 (commercial fast chargers): These require an electrical permit and often a building permit. Fire marshal review is common for commercial DCFC installations.

Permit authority in New Hampshire is at the municipal level. While the state sets minimum standards through the State Building Code (NH RSA 155-A) and electrician licensing laws (NH RSA 319-C), your town or city building department issues the permit and conducts inspections.

A licensed New Hampshire electrician must perform or supervise the work. Some municipalities may allow homeowners to pull permits for owner-occupied, single-family residences, but you must confirm this policy with your local building office. The typical timeline from application to approval is one to four weeks.

New Hampshire's Governing Codes and State-Level Authority

EV charger installations are governed by the state building code and electrician licensing laws, which are enforced at the local level.

The State Building Code (RSA 155-A)

NH RSA 155-A establishes the State Building Code, which adopts the International Building Code (IBC) and International Residential Code (IRC) as the minimum standard for construction. Municipalities have the authority to enforce the code and may adopt more restrictive local amendments.

Electrician Licensing and the NEC (RSA 319-C)

NH RSA 319-C establishes the Electricians' Licensing Board and requires that electrical work be performed by licensed electricians. New Hampshire adopts the National Electrical Code (NEC) as its standard for electrical safety. The NH Office of Professional Licensure and Certification (OPLC) oversees electrician licensing.

Which NEC edition is currently in force: To confirm the current adopted edition of the NEC, consult the NH OPLC Electricians' Board directly at oplc.nh.gov or call (603) 271-2152.

NEC Article 625

NEC Article 625, "Electric Vehicle Power Transfer System," contains the specific technical requirements for EVSE installations. It governs circuit sizing, equipment specifications, and installation methods. Your local inspector will use Article 625 as the standard for your inspection.

HOA Preemption

New Hampshire has not enacted a statewide "right to charge" law that would preempt homeowners' association (HOA) or condominium association restrictions on EVSE installation. If your HOA governing documents restrict installation, you must work through the association's approval process or consult a New Hampshire attorney.

Permit Process Step by Step: Residential vs. Commercial Installations

Step 1: Contact Your Local Building or Code Enforcement Office

Permitting is a municipal function. Contact your town or city building department to understand its specific application process and requirements. Find your local office through the NH Municipal Association directory at nhmunicipal.org or your municipality's official website.

Step 2: Submit Your Permit Application

Most New Hampshire municipalities require the following for an EVSE electrical permit:

  • Completed electrical permit application form
  • Load calculation for your existing electrical panel
  • Panel schedule showing existing and proposed circuits
  • Equipment specifications for the charger, including its UL listing
  • Site plan or diagram showing circuit routing (more common for commercial)

Commercial applications typically require a full electrical plan prepared by a licensed professional.

Step 3: Pay the Permit Fee

Fees are set by each municipality and vary widely. Verify the current fee with your building department before submitting your application.

Step 4: Inspections

A final inspection is required after the charger is installed. If wiring is concealed in walls, a rough-in inspection may also be necessary before closing the walls. Commercial projects often require multiple inspections.

Step 5: Receive Your Certificate of Completion

After passing the final inspection, the municipality will issue an approved inspection card or certificate of completion. Retain this document for utility rebate applications and tax records.

Utility Notification

If your installation requires a service upgrade, contact your electric utility (e.g., Eversource NH, Liberty Utilities) early in the process to coordinate their requirements and schedule.

Permit Fees and Timelines: What to Expect by Installation Type

The fees below are typical ranges. Each municipality, such as Manchester, Nashua, or Concord, sets its own fee schedule. NH RSA 155-A authorizes municipalities to set permit fees to cover enforcement costs.

Installation TypeTypical Permit Fee (NH)Inspections RequiredAvg. Approval Timeline
Level 1, existing outlet$0 (no permit)NoneImmediate
Level 2 residential, new circuit$50 to $1501 to 21 to 3 weeks
Level 2 commercial, new panel/service$100 to $500+2+2 to 4 weeks
DCFC Level 3 commercial$300 to $1,000+Multiple, incl. fire4 to 8 weeks
  • Permit fees may be flat rates or based on project valuation.
  • Expedited review is not typically offered by New Hampshire municipalities.
  • A service upgrade adds utility processing time to the project timeline.

Electrical and Safety Requirements Specific to NH EV Charger Installations

These are the key technical requirements your inspector will verify.

Circuit Requirements (NEC Article 625)

Level 2 EVSE requires a dedicated branch circuit. The circuit's overcurrent protection (breaker) must be sized for at least 125% of the charger's continuous load.

Charger OutputMinimum Circuit BreakerMinimum Wire Gauge (copper)
16A (3.8 kW)20A12 AWG
32A (7.7 kW)40A8 AWG
48A (11.5 kW)60A6 AWG
80A (19.2 kW)100A3 AWG

GFCI Protection

The NEC requires GFCI protection for receptacles in garages and outdoor locations. If your Level 2 EVSE is plug-in (not hardwired) and located in one of these areas, the receptacle must have GFCI protection.

Conduit and Weatherproofing

Outdoor wiring must be run in appropriate conduit. All outdoor equipment, including the EVSE unit and any receptacles, must be weatherproof and rated for wet or damp locations.

Panel Capacity

Your electrician must perform a load calculation to confirm that your existing electrical panel can safely support the added load from the EV charger. If the panel is at or near capacity, a service upgrade or a load management system may be required.

Equipment Listing

The EVSE must be listed by a nationally recognized testing laboratory (NRTL), such as UL. The inspector will check for the listing mark on the equipment.

Commercial and Public EVSE: ADA Considerations

Publicly accessible EVSE installations must comply with the Americans with Disabilities Act (ADA) Standards for Accessible Design. This affects parking space design, charger placement, and reach ranges. For questions on ADA compliance, consult the NH Human Rights Commission or the US Access Board.

Smart Charger Requirements

New Hampshire does not mandate smart or networked chargers for residential installations. However, commercial projects receiving grant funding from the NH Department of Environmental Services (NHDES) may be required to use networked chargers as a condition of the grant.

NH Incentives and Utility Programs That Interact With Permitting

Proof of a completed and approved permit is required for nearly all rebate and tax credit programs.

Utility Rebate Programs

Eversource NH and Liberty Utilities NH have offered EV charger rebate programs. Consult the utilities directly for current program status, rebate amounts, and eligibility requirements. Applications require proof of permitted installation. NH Electric Co-op members should contact the co-op for information on its programs.

NHDES Clean Vehicle Programs

NHDES sometimes offers EVSE rebate programs funded by state or federal sources. Check the NHDES Clean Transportation program website at des.nh.gov for current funding availability. Permit documentation is required for reimbursement.

Volkswagen Settlement Funds

New Hampshire has used Volkswagen settlement funds, administered by NHDES, to support public EV charging infrastructure. These funds are typically distributed through competitive grant solicitations.

Federal Tax Credit (26 U.S.C. § 30C)

The federal Alternative Fuel Vehicle Refueling Property Credit may cover a percentage of EVSE installation costs. Use IRS Form 8911 to claim the credit. Your permit and inspection records serve as key documentation. Consult a tax professional regarding eligibility, as the credit has income and location-based requirements.

Next Steps: Who to Contact and How to Get Your Permit

Step 1: Find your local building department. Use the NH Municipal Association directory at nhmunicipal.org or your town's website to find your local code enforcement office. Ask about their specific requirements for EVSE permits.

Step 2: Verify your electrician's NH license. Use the OPLC license lookup tool at oplc.nh.gov to confirm your electrician has an active license. The OPLC Electricians' Board can be reached at (603) 271-2152.

Step 3: Contact your utility about service capacity and rebates. Call your electric utility (Eversource NH, Liberty Utilities, or NH Electric Co-op) to discuss your project and inquire about available rebates.

Step 4: Check NHDES for active state incentive programs. Visit des.nh.gov or call NHDES Clean Transportation at (603) 271-2956 to ask about current state-level rebate programs.

Step 5: Retain all permit records after final inspection. Keep copies of your permit, inspection reports, and certificate of completion for rebate applications and tax purposes.

For Commercial Projects

Engage a licensed electrical engineer to conduct a load study and prepare electrical plans before applying for a permit.

For HOA Disputes

If your HOA denies an EVSE installation request, your options are to use the HOA's internal appeals process or consult a New Hampshire attorney specializing in real estate or condominium law.
