Electrical Permit Guide for Hawaii 2026
Permit costs, processing times, NEC edition, licensing authority, and the rules that are actually enforced in Hawaii.
Quick Facts: Hawaii Electrical Permits
Typical Permit Cost
Hawaii has no statewide electrical permit fee — every permit is issued by one of the four counties (City and County of Honolulu, Hawaii County, Maui County, or Kauai County) under its own ordinance and budget schedule. Honolulu electrical permits run roughly $25–$200 for residential service work and per-circuit add-on fees under ROH Chapter 18 (service-entrance fees scale with amperage: 60–99A, 100–199A, 200–299A, 300–399A tiers). Maui electrical permit fees are set annually by Maui County budget ordinance (Maui County Code 16.18B) and computed from quantities and service size. Hawaii County and Kauai use similar quantity-and-service-size schedules under Hawaii County Code Chapter 5D and Kauai County Code Chapter 13. On top of every contractor invoice, Hawaii General Excise Tax (GET) applies — 4.5% on Oahu (4% state plus 0.5% county surcharge under HRS 237-8.6), 4.5% on Hawaii County and Kauai (effective 2020 and 2019 respectively), and 4% on Maui — and contractors typically pass it through at 4.712% per Department of Taxation Tax Facts 37-1.
Processing Time
Highly variable by county and the single biggest pain point in Hawaii. Standalone electrical permits (panel swap, EV charger, sub-panel) on Oahu can clear DPP ePlans/HNL Build review in 1–4 weeks once the application is fully complete; permits attached to a building permit can take far longer — a 2025 Hawaii DBEDT report on Honolulu permit delays found median residential building-permit review running roughly six months in late 2023, with electrical-bundled projects sometimes sitting in "prescreen" for a year or more. Maui issues electrical permits within 30 days of a complete MAPPS application per the Electrical Permit and Inspection Section posted standard. Hawaii County and Kauai routinely turn standalone electrical permits in 1–3 weeks once intake is clean. Hawaiian Electric solar interconnection adds 8–12 weeks on top of the county permit on Oahu.
Online Portal Availability
Yes — every county runs its own portal, none are interoperable. Honolulu uses HNL Build (honolulu.my.site.com) with electronic plan review through ProjectDox/ePlans (mandatory for all submissions since July 1, 2023). Maui uses MAPPS Customer Self Service (mapps.co.maui.hi.us). Hawaii County uses the EPIC Online Permit System through the Department of Public Works (dpw.hawaiicounty.gov). Kauai uses Click2Gov Building Permits (egov.kauai.gov/Click2GovBP) plus an Electronic Plan Review (ePlan) portal for plan-set submission. Statewide license verification for both contractor and electrician credentials runs through MyPVL (mypvl.dcca.hawaii.gov/public-license-search) at DCCA Professional & Vocational Licensing.
Inspections
Typically 2–3 inspections per residential job: a rough/concealment inspection before drywall, a service inspection before Hawaiian Electric (or KIUC on Kauai) energizes, and a final/cover inspection. Service-only swaps (100A-to-200A panel upgrade, meter relocation) usually combine into 1–2 visits. PV interconnections add a separate Hawaiian Electric site inspection on top of the county final. Re-inspections after failed work carry an additional fee under each county posted schedule.
Hawaii Electrical Licensing
Two separate boards regulate Hawaii electrical work, both housed under DCCA Professional & Vocational Licensing (PVL): (1) the Contractors License Board, which licenses electrical contracting businesses (C-13 Electrical, C-13a Electric Sign, C-60 Solar Power Systems) under HRS Chapter 444 and HAR Chapter 16-77; and (2) the Board of Electricians and Plumbers, which licenses individual electrical workers (Journey Worker, Supervising, Maintenance, Industrial, and Specialty classifications) under HRS Chapter 448E and HAR Chapter 16-80. DCCA Professional & Vocational Licensing, P.O. Box 3469, Honolulu, HI 96801 / (808) 586-3000 / 1-844-808-DCCA / pvl@dcca.hawaii.gov.
Hawaii is unusual in licensing both the contracting business AND the individual worker. The C-13 Electrical Contractor classification under HAR 16-77 covers wiring, fixtures, conduits, raceways, and any equipment carrying less than 600 volts phase-to-phase, and includes the scope of C-15 (electronic systems) and C-60 (solar power systems). C-13a covers electric signs; C-60 covers PV-only contractors who do not want full C-13 scope. C-13 entities must employ a Responsible Managing Employee (RME) with four years of full-time supervisory experience verifiable in the past 10 years and carry $100,000 minimum general liability and workers comp. Contractor licenses renew biennially every even-numbered year. Individual workers are licensed by the Board of Electricians and Plumbers under HRS Chapter 448E: Journey Worker Electrician requires 5 years / 10,000 hours of full-time experience under a journey worker or supervising electrician (HRS 448E-5); Supervising Electrician is the higher classification authorized to direct and supervise work. Renewal is triennial by June 30 of every third year (electricians next renew in 2029); active renewal $306, inactive $12, late restoration $406. Per HRS 448E-9 it is unlawful to perform electrical work without the appropriate individual license — apprentices must work under direct supervision of a licensed worker. Critically, HRS 444-2.5 expressly bars the owner-builder exemption from covering electrical work: an owner can act as their own general contractor on their own home, but they cannot do their own electrical wiring unless they personally hold a chapter 448E license.
Electrical Code in Hawaii
Hawaii State Electrical Code (HAR Title 3, Chapter 181, adopted by the State Building Code Council under HRS Chapter 107) — Current Edition
2020 NEC (NFPA 70-2020) — STATE level. County adoption varies and is the binding code for permits.
Hawaii electrical code adoption is structured in two layers and the county layer is what actually controls your permit. The State Building Code Council (under DAGS, HRS Chapter 107) adopted the 2020 NEC as the State Electrical Code; counties had until March 14, 2024 to adopt the 2020 NEC with local amendments or have it apply as the interim county code by operation of the State Building Code Council schedule. In practice the four AHJs are not in lockstep: Honolulu (City and County) adopts the State Electrical Code by reference under ROH Chapter 17, §17-1.1, with the 2017 NEC adopted via Bill 20 (2019, Ordinance 19-20) — Honolulu has historically lagged a cycle and contractors should confirm the current ROH supplement. Hawaii County repealed its old Chapter 9 and consolidated its electrical code into Chapter 5D (Bill 44/Ordinance 20-61, June 2020), aligning with the 2017 NEC at adoption with subsequent state-driven updates. Maui County Chapter 16.18B still expressly references the 2008 NEC per Ordinance 3726 (effective June 6, 2010) on the public Electrical Permit and Inspection Section page, although it is subject to the State Building Code Council March 2024 default-to-2020 mechanism — verify the current Maui amendment status with the Electrical Section before designing. Kauai County Code Chapter 13 (Electrical Code) was last revised in 2020. Hawaii also enforces high-wind/hurricane structural provisions through the State Residential Code (2018 IRC adopted with HI amendments), which affects mast bracing, exterior conduit anchoring, and roof penetrations — wind design speed is mapped per island under SBCC tables and engineered design is required where Vult >= 130 mph.
When Do You Need an Electrical Permit in Hawaii?
Hawaii electrical permits are issued exclusively by the four counties — there is no statewide residential building department — so every job rules trace back to the County Code that applies at your property. All four AHJs (Honolulu DPP, Maui DSA, Hawaii County DPW Building Division, Kauai DPW Building Division) require a permit for new electrical installations, alterations, and most service work, with very narrow exemptions for like-for-like fixture and device swaps. HRS 444-9 and HRS 448E-9 together require that the work be performed by a licensed C-13 contractor employing licensed individual electricians; HRS 444-2.5 specifically excludes electrical work from the owner-builder exemption unless the owner personally holds a Chapter 448E electrician license. Honolulu DPP requires a building permit for any electrical work valued over $2,500 and ePlans submission is mandatory for all permits requiring plans since July 1, 2023.
Permit Required
- New service entrances, panel changes, meter relocations, and amperage upgrades (100A, 200A, 320A, 400A) — Hawaiian Electric and KIUC will not energize without the county permit and final inspection
- New branch circuits, sub-panels, kitchen and bath remodels, and additions in any of the four counties
- EV charger circuits and Level 2 EVSE (40A and 50A dedicated circuits)
- Solar PV interconnections, battery energy storage (BESS), and any grid-tied generation — also requires Hawaiian Electric or KIUC interconnection approval through the Customer Interconnection Tool / Integrated Interconnection Queue
- Electric water heater installations and heat pump water heater (HPWH) dedicated circuits — relevant given Hawaii push to electrify off solar-heated systems
- Generator transfer switches, interlocks, and standby/portable generator interconnections
- Hot tub, pool, and spa wiring with NEC Article 680 bonding
- Commercial, industrial, and multi-family (3+ unit) electrical work in all four counties
- Honolulu specifically: any electrical work valued over $2,500 (Honolulu DPP threshold)
- Renewable Energy System electrical permits on Maui (separate MAPPS permit type for PV and wind)
Typically Exempt
- Like-for-like replacement of switches, receptacles, and fixtures on existing branch circuits where no new wiring is added
- Plug-in appliance installation where an approved outlet already exists
- Public utility company work on its own equipment up to and including the meter (Hawaiian Electric and KIUC service drops up to the meter base)
- Low-voltage signaling (doorbell, thermostat, irrigation control) under 50V — confirm thresholds with the specific county
- Honolulu specifically: minor electrical repairs valued under $2,500 generally fall outside the building-permit threshold but still require licensed-electrician execution
Exempt from permit does not mean exempt from the code. Work still must comply with the edition in force at your address.
Hawaii-Specific Rules You Should Know
Four counties, four codes, four portals — no statewide AHJ
Hawaii has no statewide residential building department. Every electrical permit is issued by one of four counties — City and County of Honolulu (Oahu), Hawaii County (Big Island), Maui County (Maui, Molokai, Lanai, Kahoolawe), or Kauai County (Kauai, Niihau) — each with its own ordinance, fee schedule, code edition, and online portal. Honolulu uses HNL Build with mandatory ePlans/ProjectDox; Maui uses MAPPS CSS; Hawaii County uses EPIC; Kauai uses Click2Gov plus an ePlan portal. Out-of-state contractors expecting a single Hawaii Department of Buildings find this is the most decentralized AHJ structure of any state. Code editions in force differ by county — assume the project-specific County Code controls until you have a current confirmation from the local Electrical Section.
Two-board licensing: contractor business AND individual worker
Hawaii is one of the few states where you must hold both a Contractors License Board credential (C-13 Electrical, regulated under HRS 444 and HAR 16-77) for the business and a Board of Electricians and Plumbers credential (regulated under HRS 448E and HAR 16-80) for each individual doing the work. C-13 entities need a Responsible Managing Employee with 4 years of supervisory experience, $100,000 liability, and biennial renewal in even years. Journey Worker Electrician requires 5 years / 10,000 hours under a licensed worker per HRS 448E-5, with triennial renewal by June 30 (next cycle 2029). Per HRS 448E-9, it is unlawful to perform electrical work without the individual license — and apprentices must be directly supervised. The contractor license alone is not enough.
Owner-builder exemption does NOT cover electrical work
HRS 444-2.5 expressly carves electrical and plumbing work out of the owner-builder exemption. An owner-occupant can register as an owner-builder under HRS 444-9.1 and act as their own general contractor on their personal residence (not for sale or rent), and can hire licensed subcontractors — but they may not personally perform the electrical work unless they hold a Chapter 448E license themselves. This is enforced more strictly than in many Mainland states; Honolulu DPP and the other counties verify electrician licensing on inspection, and ratting out an unlicensed homeowner is a routine source of complaints to DCCA. Bottom line: a Hawaii homeowner pulling their own permit still has to hire a licensed electrician for the wiring.
Highest residential rooftop solar penetration in the U.S. — and net metering ended in 2015
About 45% of Hawaiian Electric single-family residential customers and roughly half of Oahu single-family homes have rooftop solar (HECO 2025 data); Hawaii leads the nation per capita. The PUC closed retail-rate Net Energy Metering to new applicants on October 12, 2015 (Decision and Order No. 33258, Docket 2014-0192) and replaced it with Customer Self-Supply (CSS, no export) and Customer Grid-Supply Plus (CGS+) under D&O established in 2017. Hawaiian Electric runs the Customer Interconnection Tool and the Integrated Interconnection Queue for all PV/BESS applications; total installed grid-connected systems exceeded 120,000 in 2025. New customers also have access to BYOD Plus (launched May 15, 2025) under PUC oversight. Plan 8–12 weeks for HECO/KIUC interconnection on top of the county electrical permit and inspection.
General Excise Tax (GET) shows on every contractor invoice
Hawaii does not have a sales tax — it has the General Excise Tax under HRS Chapter 237, levied on the contractor gross income from the job. The base rate is 4%, with county surcharges added: Oahu (City and County of Honolulu) 0.5% through December 31, 2030 under HRS 237-8.6, plus matching surcharges on Hawaii County (0.5%) and Kauai (0.5%); Maui County is currently 4% with no surcharge. Per Department of Taxation Tax Facts 37-1, contractors who visibly pass GET through to the customer use the gross-up rate of 4.712% on a 4.5% county or 4.166% on a 4% county and label it "GET" on the invoice — never "sales tax." Customers should expect every line item on a Hawaii electrical invoice to be marked up accordingly.
Hurricane wind code drives mast bracing and exterior conduit
Hawaii adopts the State Residential Code (2018 IRC family with state amendments via the SBCC) plus the State Building Code, with island-specific wind design speeds. Per Hawaii residential code §R301.2 and SBCC tables, engineered design is required where Vult is greater than or equal to 130 mph; significant portions of windward Oahu, exposed Maui shorelines, and parts of the Big Island fall in this band. The hurricane provisions affect electrical work primarily through service-mast bracing, anchorage of exterior conduit and disconnects, and securement of PV racking and conduit penetrations against design wind speeds up to 180 mph. Inspectors look for compliance with manufacturer wind ratings and Hawaii-amended fastener spacing — out-of-state contractors used to Mainland service-mast standards routinely fail first inspection.
Lava Zones 1 and 2 (Hawaii Island) — insurance gate, not a permit moratorium
The USGS Hawaiian Volcano Observatory lava-zone map classifies Hawaii Island land into hazard zones 1–9. Hawaii County does NOT prohibit building or electrical permits in Lava Zones 1 (Kilauea, Mauna Loa rift zones) or 2, but private insurers have largely withdrawn from those zones — only the state-created Hawaii Property Insurance Association still writes residential coverage in LZ 1–2. Without a homeowner policy, mortgages are unavailable, which kills financing on most projects but does not block a cash-built permit. After the 2014–2018 Puna lava flows, the moratorium imposed by some carriers was lifted by Act 32 (2015). Electricians working in Lava Zones 1–2 (Puna District: Pahoa, Kalapana, Leilani Estates) should confirm the customer has financing and insurance lined up before beginning work — most jobs in these zones are owner-financed rebuilds.
Honolulu permit delays are a known structural problem
A May 2025 DBEDT report ("Assessing the Cost of Building Permit Delays in Honolulu: 2022–2023") and Civil Beat investigations documented median Honolulu residential permit review times of roughly 330 days at the worst point in late 2023, with electrical work bundled into building permits frequently spending months in DPP "prescreen" before reaching code review. Standalone electrical-only permits (panel swap, EV charger, sub-panel) move faster — often 1–4 weeks — but anything tied to a structural permit is exposed to the systemic backlog. The mandatory shift to ePlans/ProjectDox for all submissions on July 1, 2023 was the headline streamlining move; processing has improved since but contractors should still build schedule contingency on Oahu jobs. Maui (30-day standard), Kauai, and Hawaii County run materially faster on standalone electrical work.
Permit Cost Drivers in Hawaii
Typical residential fee ranges. Actual fees vary by city and current-year schedule. Always verify at application.
| Work Type | Typical Fee | What Drives Variance |
|---|---|---|
| Honolulu electrical permit (panel/service upgrade) | $25–$200 | Per ROH Chapter 18; service-entrance fees scale by amperage tier. Plan-review fee adds 20% of the building permit fee (capped at $25,000) when bundled with a structural permit. |
| Maui electrical permit | Set by annual budget ordinance | Maui County Code 16.18B; fees by quantity and service size. Renewable-energy system permits are a separate MAPPS permit type. (808) 270-7255. |

| Hawaii General Excise Tax pass-through | 4.166%–4.712% on every invoice | Per HRS Chapter 237 and DOT Tax Facts 37-1. 4.5% on Oahu/Hawaii Island/Kauai (state + county surcharge), 4% on Maui. Must be labeled "GET," not "sales tax." |
| Re-inspection fee | Varies by county | Each county sets its own re-inspection fee under its electrical code chapter. Triggered by failed inspection or unready work at scheduled visit. |
Hawaii Electrical Permit FAQs
Who issues electrical permits in Hawaii?
One of the four counties — never the state. City and County of Honolulu (Department of Planning and Permitting / DPP) handles all of Oahu through HNL Build with mandatory ePlans submission. Maui County (Department of Public Works, DSA) handles Maui, Molokai, Lanai, and Kahoolawe through MAPPS. Hawaii County (DPW Building Division) handles the Big Island through EPIC. Kauai County (DPW Building Division) handles Kauai and Niihau through Click2Gov. Each county has its own fee schedule, code edition, and inspection staff.
Which NEC edition does Hawaii enforce in 2026?
It depends on your county. The State Building Code Council adopted the 2020 NEC as the State Electrical Code, with a March 14, 2024 deadline for counties to adopt the 2020 NEC locally or have it apply as an interim county code. Honolulu adopted the 2017 NEC under Bill 20 (Ord. 19-20) and ROH §17-1.1; Hawaii County Chapter 5D took effect under Bill 44 / Ord. 20-61 (June 2020); Maui County Code 16.18B still references the 2008 NEC on its posted page (subject to SBCC default-up); Kauai County Code Chapter 13 was revised in 2020. Always confirm with the specific county Electrical Section before pulling a permit.
Can a Hawaii homeowner do their own electrical work?
Almost never. HRS 444-2.5 explicitly excludes electrical and plumbing work from the owner-builder exemption — even if you register as an owner-builder under HRS 444-9.1 to act as your own general contractor, you cannot personally perform the wiring unless you hold a Chapter 448E electrician license. The only practical path for an unlicensed homeowner is to hire a C-13 Electrical Contractor employing licensed Journey Worker or Supervising Electricians. This is one of the most strictly enforced owner-builder limits in the country.
What licenses does a Hawaii electrical contractor need?
Two separate credentials, both administered under DCCA Professional & Vocational Licensing. The business needs a Contractors License Board C-13 (Electrical) classification under HRS Chapter 444 and HAR 16-77 — requiring a Responsible Managing Employee with 4 years of supervisory experience, $100,000 minimum liability, workers comp, and biennial renewal in even years. Each individual doing the work needs a Board of Electricians and Plumbers license under HRS Chapter 448E (Journey Worker Electrician requires 5 years / 10,000 hours; Supervising Electrician requires journey worker experience plus exam). Apprentices may work only under direct supervision of a licensed worker per HRS 448E-9.
How does solar interconnection work after the end of net metering?
Hawaii closed retail-rate Net Energy Metering to new applicants on October 12, 2015 under PUC Decision and Order No. 33258 in Docket 2014-0192. New residential PV systems sign up under Customer Self-Supply (CSS — no grid export) or Customer Grid-Supply Plus (CGS+ — utility-curtailable export) tariffs, plus the BYOD Plus battery program launched May 15, 2025. Apply through Hawaiian Electric Customer Interconnection Tool and track status in the Integrated Interconnection Queue. Expect 8–12 weeks for HECO interconnection on Oahu on top of the county permit and inspection. KIUC on Kauai runs its own program.
Why is Hawaii General Excise Tax on my electrical invoice?
Hawaii does not have a sales tax — it taxes the contractor gross income from the job under HRS Chapter 237 (General Excise Tax). The base GET is 4%, with county surcharges adding 0.5% on Oahu, Hawaii Island, and Kauai (Maui currently has no surcharge). Per Department of Taxation Tax Facts 37-1, contractors who visibly pass GET to the customer use the gross-up rate of 4.712% (Oahu/Big Island/Kauai) or 4.166% (Maui) and must label the line "GET" or "Hawaii General Excise Tax" — never "sales tax." This applies to materials, labor, and total job cost.
What if I skip the permit?
Hawaiian Electric and KIUC will not energize new service or interconnect a PV system without the county permit and passing inspection — that is the strongest practical enforcement mechanism. Each county can also issue stop-work orders, double permit fees, require finished surfaces to be opened for inspection, and pursue license-action complaints with DCCA against any involved contractor. For PV specifically, an unpermitted system cannot be added to the Integrated Interconnection Queue, which means no legal grid export. Insurance carriers also typically deny claims on damage caused by unpermitted electrical work.
Are Lava Zones 1 and 2 on the Big Island a permit problem?
Hawaii County does not refuse building or electrical permits in Lava Zones 1 or 2 (the active and high-risk zones around Kilauea and Mauna Loa rift zones, including Puna District communities like Pahoa, Kalapana, and Leilani Estates). The bigger issue is insurance: most private carriers have withdrawn from LZ 1–2, leaving only the state-created Hawaii Property Insurance Association writing residential policies. Without insurance, mortgages are unavailable, so most jobs in these zones are owner-financed cash builds. After the 2014–2018 Puna eruptions, Act 32 (2015) lifted the carrier-imposed moratorium on writing new policies in affected lava zones.
