Quick answer
Installing an EV charger is electrical work, and ROH 18-3.1(a)(2) requires a building permit for any electrical work. DPP names EV charger installation among its expedited clean-energy building permit projects, and its Quick Permit flowchart lists 'EV Charging Station' as an instant online scope for single-family and detached-duplex lots outside flood zones with no advisory or violation. Plugging a car into an existing outlet involves no installation and needs nothing.

What an EV charger permit costs in Honolulu
How to apply in Honolulu
In Honolulu, in most of the US, installing a Level 2 (240 volt) home EV charger is handled as an electrical permit built around a load calculation and a single line diagram showing the new dedicated circuit. A Level 1 charger that simply plugs into an existing 120 volt outlet typically needs no permit unless new wiring is added.
What most EV charger permit applications include:
- For Honolulu, a Level 2 charger needs its own dedicated 240 volt circuit and requires an electrical permit with inspection, since each outlet installed for EV charging must be fed by an individual branch circuit with no other outlets on it (NEC 625.40).
- For Honolulu, the application includes an electrical load calculation showing the existing service panel has enough spare capacity for the added EVSE demand, worked out using the standard dwelling load calculation method (NEC 220.83).
- For Honolulu, the breaker or other overcurrent device feeding the charger must be sized for continuous duty, rated at not less than 125 percent of the equipment's maximum load (NEC 625.41).
- Plan submittal typically includes a single line diagram showing conductor size, breaker size, conduit, and panel rating, plus the charger's manufacturer specifications, since the EVSE itself must be a listed product (NEC 625.5).
- For charging equipment rated over 60 amps or over 150 volts to ground, the application has to show a disconnecting means installed in a readily accessible location and capable of being locked open (NEC 625.43).
- For Honolulu, the charger must be shown connected and fastened in place according to the manufacturer's installation instructions, whether it is hardwired or a plug in unit on a dedicated receptacle (NEC 625.44).

Inspections and closing out your permit
In Honolulu, a Level 2 EV charger installation gets a rough wiring inspection if any new conductors will be hidden inside walls, ceilings, or run underground, then a final inspection that checks the dedicated circuit, breaker sizing, any required GFCI protection, the disconnect, and the charger's listing before the permit closes.
- In Honolulu: if new EVSE conductors will be concealed in a wall or ceiling, or run underground, they must pass a rough wiring inspection before being covered, since that inspection confirms the dedicated branch circuit required for the charger (NEC 625.40).
- In Honolulu: at final inspection, the breaker or other overcurrent device serving the charger is checked to confirm it is properly rated for the continuous EV charging load (NEC 625.41).
- In Honolulu: any receptacle installed for EV charging, as opposed to a hardwired connection, has to be checked for ground fault circuit interrupter protection (NEC 625.54).
- In Honolulu: where the EVSE is rated over 60 amps or 150 volts to ground, the inspector confirms a lockable, readily accessible disconnecting means was installed (NEC 625.43).
- In Honolulu: the inspector verifies the charger, along with its fittings and associated equipment, carries a nationally recognized testing laboratory listing (NEC 625.5).
- In Honolulu: mounting height is checked against the manufacturer's instructions, with the coupling means generally required to sit at least 18 inches above an indoor floor or 24 inches above outdoor grade unless the equipment is listed otherwise (NEC 625.50).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Honolulu permit portal or by phone at (808) 768-8000.

- You can apply through the Honolulu permit portal or contact the City and County of Honolulu Department of Planning and Permitting (DPP), Building Division directly. The links are listed on this page.
- Can a homeowner pull an EV charger permit themselves in Honolulu?
- Under Hawaii law (HRS 444-2(7), 444-2.5, 444-9.1, 444-23(e)): Hawaii lets owners or lessees build or improve residential or farm buildings for their own use, or for use by their grandparents, parents, siblings, or children, without a contractor's license, as long as the building is not offered for sale or lease. The owner must register for the exemption with the county when applying for the building permit, supervise the work, hire licensed subcontractors for any licensed work, and use licensed electricians and plumbers for electrical and plumbing work unless the owner holds that license. Selling or leasing the structure within one year after final county inspection is treated as evidence it was built for sale, unless the permit valuation was under $10,000, the buyer is the owner's employee, or the Contractors License Board finds an unforeseen hardship. A violation carries a fine of up to $5,000 or 50% of the permitted construction value, whichever is greater, for a first offense, and bars the owner from the exemption for three years. Confirm how Honolulu applies this before you apply.
