EV Charger Permit Requirements in Hawaii (2024)

If you're installing a Level 2 (240V) EV charger in Hawaii, you need a building or electrical permit from your county, not the state. Level 1 plug-ins generally do not. A licensed electrical contractor must pull the permit, and the process typically takes 2 to 6 weeks.

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

Yes, for nearly any Level 2 (240V) EVSE installation.

Level 1 (120V, standard outlet): Plugging into an existing outlet requires no permit in any Hawaii county if no new circuit or panel work is involved.

Level 2 (240V, dedicated circuit): A building or electrical permit is required in all four counties. A new 240V circuit requires an electrical permit under state and county codes.

DC Fast Chargers (DCFC): Require a permit plus a separate utility interconnection review from the applicable island utility (Hawaiian Electric / HECO, Maui Electric / MECO, or Hawaii Electric Light / HELCO).

• Permits are issued at the county level. There is no single statewide EVSE permit.
• A Hawaii-licensed electrical contractor must pull the permit in all four counties. Homeowners generally cannot self-permit this type of electrical work.
• The timeline from application to final inspection is roughly 2 to 6 weeks for residential L2 installations.
• Hawaii has not adopted a statewide permit-streamlining rule for residential EVSE. Each county sets its own process.
• The Hawaii Public Utilities Commission (PUC) regulates utility interconnection for EVSE.

Hawaii State Law and Statutes Governing EV Charger Installations

State laws establish minimum requirements, which counties may supplement.

HRS § 291-71: EV-Ready Parking Requirements

New parking facilities with 100 or more stalls must include a percentage of EV-ready or EV-installed spaces (HRS § 291-71). For new construction or substantial renovation of a commercial parking structure meeting this threshold, the permit scope will include EV infrastructure as a code requirement. Verify current stall thresholds and percentage requirements with your county building department, as proposed 2023 legislation (SB 370) did not advance.

HRS § 514B-104: Condominium Right to Charge

Condominium associations cannot unreasonably restrict an owner from installing an EV charger in a parking stall that the owner owns or has exclusive use of (HRS § 514B-104). The association may require the owner to use a licensed contractor, carry insurance, and restore the stall to its original condition upon sale.

HRS § 196-7.5: State Energy Policy

State policy encourages EV infrastructure deployment at state facilities (HRS § 196-7.5). This statute drives procurement at state-owned properties but does not directly affect private permit requirements.

Electrical Contractor Licensing: HAR Title 16

All electrical work for EVSE installation must be performed by a contractor holding a valid Hawaii electrical contractor license under HAR Title 16 (Department of Commerce and Consumer Affairs, Professional and Vocational Licensing). The appropriate license classification for this work is C-13 Electrical. Verify any contractor's license status through the DCCA PVL online lookup before signing a contract.

National Electrical Code Adoption

Hawaii adopts the National Electrical Code (NEC) statewide. NEC Article 625 governs EV charging system installation. Consult the Hawaii Department of Accounting and General Services (DAGS) or your county building department to confirm the currently adopted NEC edition, as adoption cycles vary.

Hawaii PUC and Utility Interconnection

The Hawaii Public Utilities Commission regulates how utilities process interconnection applications for customer-sited equipment like EV chargers. These regulations are most relevant for DCFC installations that place a significant load on the grid.

County-by-County Permit Requirements and Fees

The information below is for general guidance. Fee amounts and processing times change. Verify all details directly with the appropriate county department before starting a project.

City and County of Honolulu (DPP)

The Honolulu Department of Planning and Permitting (DPP) is the most digitized. Residential L2 installations on existing panels with adequate capacity may receive over-the-counter approval when submitted through the ePlans portal with a complete package. Circuits over 30A require an electrical permit. Your licensed contractor must pull the permit and submit load calculation documentation. Confirm current fees on the DPP fee schedule page on the Honolulu.gov website.

Maui County (Department of Public Works)

Maui DPW handles electrical permits for EVSE. Submissions require a single-line electrical diagram, load calculation, and equipment specification sheet. Expedited review for simple residential projects may be available. Consult the Maui County Department of Public Works for current fees and procedures.

Hawaii County (Department of Public Works)

For Hawaii County (the Big Island), the electrical permit process is consistent across zoning types, but inspection scheduling in remote areas can add time. Confirm any special requirements for your project area with the Hawaii County Department of Public Works Building Division. Consult the Hawaii County DPW for its current fee schedule.

Kauai County (Building Division)

Kauai's Building Division processes electrical permits for EVSE. Review queues can be longer during busy periods. Confirm online application availability and current fees directly with the Kauai County Building Division before submitting.

Step-by-Step Permit Application Process

Installing before a permit is issued can result in failed inspections and voided eligibility for utility rebates.

Step 1: Determine Charger Level

Confirm if you are installing L1 (120V, no permit if no new circuit), L2 (240V, permit required), or DCFC (permit plus utility interconnection).

Step 2: Hire a Hawaii-Licensed Electrical Contractor

The contractor must hold a valid C-13 Electrical license. Verify the license through the Hawaii DCCA Professional and Vocational Licensing (PVL) online search at pvl.ehawaii.gov. The contractor pulls the permit.

Step 3: Contractor Prepares Documentation

The contractor prepares a single-line electrical diagram, a load calculation demonstrating panel capacity, and an equipment specification sheet. These are required for submission in all counties.

Step 4: Submit Permit Application

Submit the application package to the appropriate county department: DPP for Honolulu, DPW for Maui and Hawaii County, or the Building Division for Kauai. Honolulu accepts submissions via its ePlans portal; confirm the method with other counties.

Step 5: Pay Permit Fee

Fees are due at submission or upon issuance, depending on the county. Consult the county's current fee schedule.

Step 6: Await Plan Review

Simple residential projects may receive same-day approval in Honolulu. Other projects take longer. Do not begin installation until the permit is issued.

Step 7: Install After Permit Issuance

The contractor installs the charger after the permit is issued, complying with the adopted edition of NEC Article 625 and any county amendments.

Step 8: Schedule and Pass Electrical Inspection

Contact the county inspection office to schedule. The inspector verifies the installation matches the approved plans and meets code.

Step 9: Receive Final Sign-Off

Retain the final, signed-off permit document for utility rebate applications and tax credit documentation.

DCFC Addition

For DC Fast Chargers, submit a utility interconnection application to HECO, MECO, or HELCO concurrently with the county permit application. Utility review timelines are separate from and often longer than county permit review.

What Changed Recently: 2023 Legislative Activity Affecting EV Chargers

SB 370 (2023 Regular Session)

SB 370 would have expanded EV charging requirements for parking facilities under HRS § 291-71. The measure was deferred by the Senate Committee on Energy, Environment, and Technology and did not advance in the 2023 session (SB 370, 2023 Hawaii Regular Session, OpenStates). Current requirements remain in effect.

HB 347 (2023 Regular Session)

HB 347 addressed accessibility requirements for EV charging spaces. It passed out of the House Committee on Energy and Environmental Protection with amendments and was referred to the Finance Committee (HB 347, 2023 Hawaii Regular Session, OpenStates). The bill's final status should be verified on the Hawaii Legislature's website at capitol.hawaii.gov.

Hawaii's Clean Energy Mandate

HRS § 269-92 requires Hawaii's electric utilities to source 100% of their electricity from renewable energy by 2045. This mandate may drive future efforts to streamline EVSE permitting at the county level, though no statewide rule has been adopted.

County Fee Schedule Updates

County permit fee schedules are updated periodically. Always verify current fees directly with the relevant county department before budgeting a project.

Utility Interconnection and Rebate Programs

Hawaiian Electric (HECO / MECO / HELCO)

For residential L2 chargers, utility notification requirements vary. For DCFC installations, a formal interconnection application is required. Consult Hawaiian Electric's current interconnection tariff or contact its interconnection team to determine the requirements for your specific project.

Hawaiian Electric EV Charger Rebate Programs

Hawaiian Electric has offered various EV charger rebate programs. Program availability, amounts, and eligibility change. Consult the Hawaiian Electric website to confirm if a program is currently open.

Hawaii Energy

Hawaii Energy administers clean energy incentive programs and has offered EVSE rebates. Consult hawaiienergy.com for current program availability, as funding is limited and can close without notice.

Federal Tax Credit: IRC § 30C

The Inflation Reduction Act modified the Alternative Fuel Vehicle Refueling Property Credit (IRC § 30C). The credit is subject to cost caps, prevailing wage requirements, and location-based eligibility tied to census tracts. Consult IRS Notice 2023-29 and a qualified tax professional for current rules. File using IRS Form 8911.

GEMS Loan Program

The Green Energy Market Securitization (GEMS) program, administered by the Hawaii Green Infrastructure Authority, has provided low-interest financing for clean energy projects. Consult the authority for current program availability and eligibility for EVSE projects.

Documenting Permit Completion for Rebates

Utility rebate programs and the IRS tax credit require proof of a completed, inspected installation. Retain your permit application, final signed-off permit, equipment specification sheet, and proof of purchase.
