Hawaii Low Voltage License Requirements (2026)

Hawaii does not use one standalone credential called a “low-voltage license.” The statewide DCCA Contractors License Board classifications are C-15 Electronic systems contractor, C-15a Fire and burglar alarm contractor, and C-15b Telecommunications contractor. Their scopes differ: C-15 covers listed electronic systems such as public address, intercom, CATV, door-opening, and fire/burglar-alarm systems; C-15a is limited to central fire and burglar alarm systems; and C-15b covers telephone, computer, data, cabling, wiring, and fiber-optic systems. Those three classifications do not include conduit installation. C-13 Electrical contractor is broader: it covers electrical work below 600 volts phase-to-phase, conduit work, and the C-15 scope. Match the requested classification to the actual contract and coordinate county permits and the separately licensed electrician who performs electrical work.

Regulatory Body

Under HRS chapter 444; HAR chapter 16-77, Hawaii Department of Commerce and Consumer Affairs — Professional and Vocational Licensing Division, Contractors License Board (DCCA-PVL CLB) is the body that issues this license and enforces compliance with it. The Contractors License Board issues Hawaii’s statewide contractor classifications. The DCCA Board of Electricians and Plumbers separately licenses individual electrical workers; counties issue and inspect project permits.

Eligibility Requirements

Applicants must be at least 18 years old. Applicants must provide a Social Security Number. The cited application does not state a Hawaii-residency requirement, but every licensed contractor must maintain a definite Hawaii place of business where legal process can be served; a post-office box is not sufficient. Entity applicants also need the applicable business-registration and responsible-managing-employee arrangements.

Good moral character

The Board requires a reputation for honesty, truthfulness, financial integrity, and fair dealing. Answer the current application disclosure questions fully and provide requested explanations.

Background investigation

The contractor application requires disclosures about prior licenses, financial matters, and other listed matters. The cited contractor materials do not establish a blanket fingerprint or criminal-background-check requirement for every C-15, C-15a, or C-15b applicant.

Experience and Education

The applicant must document and verify at least Four years of supervisory experience in the requested classification within the ten years immediately before filing. The application calls for on-site supervision and direction of employees; it recognizes experience reported at journeyman, foreman, supervisor, contractor, and related levels when it demonstrates the required supervisory work.. Keep payroll, tax, project, or supervisor records to support the claim, as the board can request proof for any period within its lookback window.

Accepted proof of experience or eligibility

• Current CLB application and $50 nonrefundable application fee
• At least three notarized experience certificates from people with direct knowledge of the qualifying supervisory experience
• Chronological History of Projects form for each requested classification
• Financial statement, credit report, and Hawaii tax clearance
• Entity/RME documents and business-registration records when applicable

Education substitution

The cited current application does not say that an apprenticeship, degree, NICET credential, or manufacturer training substitutes for the four-year supervisory-experience requirement. Obtain written CLB guidance before treating education as a substitute.

Exam Requirements

The examination requirement has not been established in this record. Confirm it with the authority before applying. Provider or process notes: PSI Services, LLC, after Contractors License Board approval.

Examination fee: CLB approval is required before PSI registration. The Board’s current examination page directs applicants to PSI for the current classification bulletin, registration, examination fees, retake rules, references, question counts, and passing standards; do not rely on the former fixed PSI fee or C-13 exam details.

Retake policy: Applicants must pass the required examination(s) within six months of becoming eligible or file a new application. The broader application process is subject to the one-year abandonment rule.

Insurance and Bonds

The cited state source set does not require a contractor license surety bond for this credential. Contractors should still confirm project-specific bond, permit-bond, or public-works bond requirements before bidding.

General liability

Before issuance, the current contractor requirements call for comprehensive bodily-injury liability coverage of at least $100,000 per person and $300,000 per occurrence, plus at least $50,000 property-damage coverage per occurrence. Active contractors must keep required coverage continuous.

Workers' compensation

Submit workers’ compensation coverage from an authorized insurer unless an approved Chapter 386 exclusion applies. Sole proprietors with no employees may use the Board’s exclusion form. A lapse in required liability or workers’ compensation coverage automatically forfeits the license unless continuous coverage is timely restored.

Additional financial requirements

The current application requires a financial statement and credit report. It does not establish the former $5,000 working-capital rule. A contractor bond is required only when CLB imposes one; the cited materials do not establish a blanket C-15/C-15a/C-15b bond amount.

Renewal and Continuing Education

Renewal of the Hawaii C-15 Electronic Systems Contractor License (Low Voltage) comes due every 2 years. As cited, the renewal fee stands at $338. All contractor licenses renew by September 30 of every even-numbered year. The current active entity/sole-proprietor renewal cost is $338; RME and inactive fees differ. Active entities and sole proprietors need matching, current Hawaii tax clearance and continuous required insurance.

Continuing education: The cited current CLB materials do not establish a general continuing-education requirement for these contractor classifications. Confirm any current Board or classification-specific requirement when renewing.

Reciprocity

The NASCLA Accredited Examination is not accepted by Hawaii for this classification.

The cited current CLB materials do not establish reciprocity or an out-of-state examination waiver for C-15, C-15a, or C-15b. Out-of-state applicants should use the Hawaii process unless CLB gives written direction otherwise.

Low Voltage Licensing in Other States

Contractors working near a state line, or weighing where to qualify first, should compare Hawaii's requirements against the states most often compared against it before committing to an application:

• California Low Voltage License Requirements — California C-7 Low Voltage Systems Contractor
• Washington Low Voltage License Requirements — Washington limited-energy and telecommunications electrical specialties — L&I
• Oregon Low Voltage License Requirements — Oregon Limited Energy Contractor (CLE) and Limited Energy Technician (LEA or LEB)
• Nevada Low Voltage License Requirements — Nevada C-2d Low-Voltage Contractor and Fire-Alarm Licensing Requirements

Step-by-Step Application Roadmap

1. Choose the classification that matches the contract. Use C-15 for its stated electronic-systems scope; C-15a for central fire/burglar-alarm systems; and C-15b for telephone, computer, data, cabling, wiring, and fiber optics. These scopes exclude conduit installation. C-13 is the broader electrical classification and includes C-15 work.
2. Check whether the chapter 444 license exemption applies. The limited exemption is for aggregate labor-and-material contracts of $1,500 or less. It never applies when a building, electrical, or plumbing permit is required, to work divided to evade the law, or outside the other statutory conditions.
3. Document four years of classification-specific supervisory work. Prepare at least three notarized experience certificates and a detailed chronological project history showing on-site supervision and direction of employees in the classification sought.
4. File the complete CLB application. Submit the $50 application fee with the experience record, financial statement, credit report, tax clearance, and required entity/RME documents. CLB publishes application deadlines and meeting dates.
5. After Board approval, use the current PSI bulletin. Register for and pass the examination(s) CLB approves for the requested classification within the current six-month window. PSI—not an old exam outline—controls current testing logistics and prices.
6. Complete issuance and staff electrical work correctly. Provide the required liability and workers’ compensation coverage and maintain a Hawaii place of business. For electrical work, the contractor must be properly staffed by a Hawaii-licensed electrician; contractor classification does not replace the individual electrician credential.
7. Obtain the project county approvals. County building/electrical permit and inspection processes are separate from state licensing. For example, the City and County of Honolulu Fire Department requires a fire-alarm acceptance inspection after installation/modification and building-permit work are complete. Confirm the exact requirements with the project county and fire authority.
8. Renew on the statewide cycle. Renew by September 30 of each even-numbered year and keep insurance, tax-clearance, entity, and RME requirements current.

Common Filing Mistakes

Drawn from the board instructions and sources cited on this page, the pitfalls below are the ones most likely to slow down or sink a Hawaii Low Voltage application.

Using an invented “C-13d” low-voltage license

HAR chapter 16-77 instead lists C-15, C-15a, and C-15b, plus the broader C-13 classification. Match the work to the stated scope and conduit limitation.

Treating C-15 as permission to install conduits

The C-15, C-15a, and C-15b scope descriptions expressly exclude conduit installation. Evaluate that work under C-13 or another appropriate classification.

Using old exam, fee, or provider details

The current DCCA examination page directs Board-approved applicants to PSI. Fixed old question counts, scores, fees, and Prometric materials are not reliable substitutes for the current PSI bulletin.

Skipping individual electrician and county requirements

State contractor classification, individual electrical-worker licensing, county permits, and fire approval are separate issues. A contractor license does not remove the need to staff and permit electrical work correctly.

Letting insurance or the renewal lapse

Required insurance must remain continuous. Licenses not renewed by the September 30 even-year deadline are unlicensed and may not practice.

Frequently Asked Questions

Does Hawaii have one low-voltage contractor license?

No. The relevant statewide classifications are C-15 Electronic systems, C-15a Fire and burglar alarm, and C-15b Telecommunications. C-13 Electrical is broader and includes C-15 work. Select the license based on the actual scope, not the informal “low voltage” label.

What can a C-15 electronic systems contractor do?

HAR chapter 16-77 lists electronic equipment and controls including public address, intercommunication, master antenna, music distribution, CATV, clocks, electronic teaching devices, electric door-opening devices, and fire/burglar alarm systems. It excludes conduit installation.

When is C-15a or C-15b the better fit?

C-15a is for central fire and burglar alarm systems. C-15b covers telephone, computer, and data systems, including associated cabling, wiring, and fiber optics. Both classifications exclude conduit installation.

Can a contractor classification replace an electrician license?

No. DCCA’s contractor requirements state that actual electrical work must be performed by a Hawaii-licensed electrician or by an employee who holds the required individual credential. County permitting may also require that electrical credential.

Do fire-alarm projects need a county approval?

Often, but the procedure is county-specific. The City and County of Honolulu, for example, requires its fire-alarm acceptance inspection before occupancy after installation/modification and the related building-permit work are complete. Check the project county and fire authority.
