Hawaii HVAC Contractor License — Requirements, Fees & Exam

Hawaii licenses the contractor (the business and its qualifying individual), not individual HVAC technicians. Prometric exam — verified from official sources.

Source-verified

Requirements below are drawn from Hawaii Contractors License Board - Professional and Vocational Licensing Division, Department of Commerce and Consumer Affairs (DCCA) (official site) and last verified July 25, 2026. Boards change fees and rules often — confirm before acting.

Requirements at a glance

Who must be licensed - Hawaii licenses the CONTRACTOR, not the individual HVAC worker: 'No person within the purview of this chapter shall act, or assume to act, or advertise, as general engineering contractor, general building contractor, or specialty contractor without a license previously obtained under and in compliance with this chapter and the rules and regulations of the contractors license board' (HRS section 444-9). HVAC sits in the specialty branch: a specialty contractor is 'a contractor whose operations as such are the performance of construction work requiring special skill ... and others whose principal contracting business involves the use of specialized building trades or crafts' (section 444-7(d)), and the board's rules assign ventilating and air conditioning work to the C-52 classification. credential_holder is 'contractor' because the chapter expressly does not apply to 'Any person who engages in the activities regulated in this chapter as an employee with wages as the person's sole compensation' (section 444-2(6)) - an employed HVAC technician therefore needs no state credential of their own. Hawaii licenses individual tradespeople only in the electrical and plumbing trades, under chapter 448E, and section 444-9.5 sets those requirements out expressly; there is no equivalent for ventilating and air conditioning work.
Experience - four years of supervisory experience within the past ten: 'Every individual applicant or RME shall have had, within the past ten years immediately preceding the filing of an application, not less than four years of supervisory experience as a foreman, supervising employee, or contractor in the particular classification in which the applicant intends to engage as a contractor' (HAR section 16-77-18(a)). Self-employed or unlicensed experience may be acceptable in the discretion of the board (section 16-77-18(b)), and contracting entities qualify through an RME who meets the requirement (section 16-77-18(c)). The board may approve certain technical training or business administration training as acceptable experience, 'but in no case shall the training count as more than one year of experience' (section 16-77-19), and may accept any reasonably equivalent knowledge, training or experience in lieu of a specific experience requirement if upon investigation it makes a detailed finding to that effect (section 16-77-20). Applicants document the experience on the board's Chronological History of Projects form, and the board's requirements sheet calls for verification of the four years of supervisory experience in the classification applied for.
Application timing - the board's monthly filing deadline: Applications are reviewed at board meetings, and the filing deadline is strict. The board's application page states that the 'Application, fee and all supporting documents to be presented to the Board MUST be received in the Board's office on or before the first Tuesday of the month TWO MONTHS prior to the scheduled meeting date.' The board's frequently asked questions state the deadline as on or before the first Tuesday of the month prior to the scheduled board meeting date, provided the application is complete, and that the board does not review applications or meet in December; these two statements of the lead time differ, so allow for the longer one and confirm the current deadline and meeting calendar with the board before filing. Once the application is approved, the qualifying individual must successfully complete the appropriate licensing examinations within six months (see also HAR section 16-77-45, under which applicants who fail to pass within six months must file a new application and application fee). The board's Application Forms and Publications page adds a one-year abandonment rule: pursuant to HRS section 436B-9, an application is considered abandoned - and will be destroyed - if the applicant fails to complete the license process within one year after filing, or fails to take and pass the examination within six months.
Insurance, bond and financial integrity: 'A licensed contractor shall have and maintain in full force and effect the following: (1) Workers' compensation insurance; unless the licensee is authorized to act as a self-insurer under chapter 386 or is excluded from the requirements of chapter 386; (2) Liability insurance from an insurance company or agency for comprehensive personal injury and property damage liability; and (3) Bond when required by the board, under section 444-16.5' (HRS section 444-11.1(a)). Failure to maintain any of these causes automatic forfeiture of the license effective as of the date of expiration or cancellation of the coverage, the board will not restore the license until satisfactory proof of continuous coverage is submitted, failure to restore within sixty days after forfeiture forfeits all fees and requires application as a new applicant, and the board may assess a fee not to exceed $1,000, impose a bond, or restrict the license as a condition of restoration (section 444-11.1(b)-(e)). On the bond: the board 'may require each licensee, applicant, individual or corporate, who is a specialty contractor to put up bond in the sum of not less than $5,000,' taking into consideration the licensee's or applicant's financial condition and experience in the field (section 444-16.5). At renewal the licensee must establish financial integrity by submitting a current state tax clearance or proof of a payment arrangement together with a statement disclosing or denying liens, undisputed debts or judgments; proof of continuously maintained workers' compensation insurance (or authorization to self-insure, or exclusion from chapter 386); proof that liability and property damage insurance has been maintained in the amounts 'Bodily injury $100,000 each person $300,000 each occurrence' and 'Property damage $50,000 each occurrence'; and proof that any surety bond imposed by the board is current (HAR section 16-77-55(a)-(b)).
Staying inside the C-52 scope - and the incidental and supplemental allowance: 'A licensee classified as a specialty contractor shall not act, assume to act, or advertise as a contractor in any classification other than those which the licensee holds' (HAR section 16-77-33(c)). The one flexibility is narrow: HRS section 444-8(c) provides that the section 'shall not prohibit a specialty contractor from taking and executing a contract involving the use of two or more crafts or trades, if the performance of the work in the crafts or trades, other than in which the specialty contractor is licensed, is incidental and supplemental to the performance of work in the craft for which the specialty contractor is licensed.' The rules define the term: '"Incidental and supplemental" is defined as work in other trades directly related to and necessary for the completion of the project undertaken by a licensee pursuant to the scope of the licensee's license' (HAR section 16-77-34). Two limits matter for HVAC specifically. The C-52 scope itself excludes electrical controls - the rule reads 'controls (other than electrical)' - and Hawaii requires electrical and plumbing work to be performed by individuals licensed under chapter 448E where an electrical or plumbing contractor's responsible managing employee is not so licensed (HRS section 444-9.5). Licensees who hold a specialty contractors license automatically hold the subclassifications of that particular specialty without examination or paying additional fees (HAR section 16-77-32(d)).
Place of business and posting: No license is issued or renewed to a contracting entity, except RMEs, that does not maintain a permanent place of business within the State - defined as 'a physical address, not a post office box number' - where the entity may be served notice and legal process and where its license is prominently displayed (HAR section 16-77-87); licensees must notify the board of a change of address (section 16-77-88), and out-of-state licensees are subject to the board's place-of-business rule for out-of-state licensees (section 16-77-89). HRS section 444-14 governs the place of business and the posting of the license. The application form for a contracting entity requires a Hawaii business address at a street address - a post office box is not acceptable for that field - in addition to a mailing address.
Renewal - biennial, on September 30 of each even-numbered year: 'The biennial renewal fee or inactive license fee, and the recovery fund, education fund, and compliance resolution fund fees shall be paid to the board on or before September 30 of each even-numbered year. These fees shall be as provided in rules adopted by the director pursuant to chapter 91. Failure, neglect, or refusal of any licensee to pay these fees and to submit all documents required by the board on or before September 30 of each even-numbered year shall constitute a forfeiture of the licensee's license' (HRS section 444-15(a)). 'Any forfeited license may be restored upon submittal of all required documents and fees, plus a penalty fee, within sixty days from September 30 of the even-numbered year' (section 444-15(b)); by rule, forfeited licenses may be restored by filing a renewal application with all required documents and fees, including the recovery and education fund fees, 'plus a penalty fee on or before November 30 of the renewal year', and 'Licensees who fail to restore their licenses by November 30 shall be required to apply as new applicants' (HAR section 16-77-51; the board's current application forms state the same November 30 date). The rules add that prior to September 30 of each even-numbered year all licensees submit the appropriate renewal fees provided in chapter 16-53 plus a contractors education fund fee of five dollars and a contractors recovery fund fee of ten dollars (HAR section 16-77-54). The board mails renewal applications to all current licensees before August 15 of the even-numbered year, but the obligation to renew does not depend on receiving one. A licensee may request that the board place an active license in inactive status; the licensee may continue inactive for the biennial period on payment of the inactive license fee, may not engage in contracting while inactive, and may reactivate at any time during the biennial period by written request under the statute (section 444-15(c)); the rule's package is fuller: an application, application fee, current financial statement, tax clearance, and credit report (application, fee and current credit report for an RME), with the board reviewing the request as if it were a new application (HAR section 16-77-56).
Continuing education is not among the board's stated renewal conditions: The conditions the rules impose for renewal are financial and administrative rather than educational. HAR section 16-77-55 provides that no license shall be renewed until the licensee continues to meet the requirements of HRS sections 444-11, 444-11.1 and 444-17 and of the chapter, 'including, but not limited to, proof of financial integrity,' and then enumerates what establishes that financial integrity: a current state tax clearance or proof of a payment arrangement plus a lien and judgment disclosure; proof of continuously maintained workers' compensation insurance or authorization to self-insure or exclusion from chapter 386; proof that liability and property damage insurance has been maintained at $100,000 each person and $300,000 each occurrence for bodily injury and $50,000 each occurrence for property damage; and proof that any surety bond imposed by the board is current. Continuing education is not among the enumerated conditions, and the board's renewal guidance describes the same documents and fees. Confirm current renewal requirements with the board before the biennial deadline.
Reciprocity - Hawaii states it has none: The board's published answer is direct: asked whether Hawaii has reciprocity agreements with other states, the Contractors License Board states 'No. All applicants must meet the same licensing and examination requirements.' An out-of-state contractor therefore applies on the same footing as any other applicant - four years of supervisory experience in the classification within the past ten years, both examination parts at seventy-five per cent, and the same insurance and financial-integrity requirements. The application forms do ask the applicant to attach a copy of each contractor's license previously held in any state, and the board retains discretion under HAR section 16-77-20 to accept reasonably equivalent knowledge, training or experience in lieu of a specific experience requirement, but neither is a reciprocity pathway.
Joint ventures and partnerships: 'No further license is required when all members of the joint venture or all partners in the partnership submit evidence to the board that all members or partners hold current contractor's licenses; provided that work to be performed is in a classification held by one of the members or partners,' with written notice to the board of all joint ventures and partnerships so formed and of the principal RME (HAR section 16-77-13(a)). Joint ventures and partnerships must obtain a license when any member or partner does not hold a current contractor's license, and all unlicensed members or partners must submit current financial statements, credit reports and a tax clearance along with the application (section 16-77-13(b)). Except as otherwise provided by law, all joint ventures and partnerships must be registered with the department's business registration division before engaging in any contracting activity, with proof of registration provided at the time of application (section 16-77-13(c)). Consistently, HRS section 444-2(8) exempts from the chapter 'Any joint venture if all members thereof hold licenses issued under this chapter.'

Legal basis

Hawaii Contractors License Board - Professional and Vocational Licensing Division, Department of Commerce and Consumer Affairs (DCCA) administers HVAC contractor licensing in Hawaii. Every figure below is verified against the board’s own official pages and dated. Who must personally hold a credential — the contractor, the business, or the individual worker — is set out under Requirements.

What it’s called

Hawaii issues an HVAC credential to the CONTRACTING BUSINESS, not to the technician. The official name is the ‘C-52 Ventilating and air conditioning contractor’ specialty classification, issued by the Contractors License Board within DCCA’s Professional and Vocational Licensing Division under HRS chapter 444 and HAR chapter 16-77. Searches for a ‘Hawaii HVAC license,’ ‘AC license,’ ‘air conditioning contractor license,’ ‘C-52 license’ or ‘ventilation contractor license’ all map to this classification. The individual who qualifies the license is called the ‘responsible managing employee’ or ‘RME’ - the term Hawaii uses where other states say qualifier or qualifying party - and a sole proprietor qualifies in his or her own right. Hawaii issues no journeyman, mechanic or technician license for HVAC work: the licensing chapter does not apply to a person engaging in the regulated activities ‘as an employee with wages as the person’s sole compensation,’ and the only trades in which Hawaii credentials individual workers are electrical and plumbing, under chapter 448E. So an employed HVAC worker in Hawaii holds no state HVAC credential; the license belongs to the business. Two things are commonly confused with the C-52. Chapter 448E electrician and plumber licenses are individual credentials for different trades, and they matter to HVAC work because electrical controls fall outside the C-52 scope. And EPA Section 608 refrigerant-handling certification is a FEDERAL credential held by the individual technician - it is neither issued by Hawaii nor a substitute for the C-52 contractor license.

License types & fees

Type	Experience	Exam	Fee
C-52 - Ventilating and air conditioning contractor (the specialty classification that covers HVAC)	Four years of supervisory experience. 'Every individual applicant or RME shall have had, within the past ten years immediately preceding the filing of an application, not less than four years of supervisory experience as a foreman, supervising employee, or contractor in the particular classification in which the applicant intends to engage as a contractor' (HAR section 16-77-18(a)). Self-employed or unlicensed experience may be acceptable in the board's discretion (16-77-18(b)), and 'Contracting entities shall qualify through an RME who meets these experience requirements' (16-77-18(c)). The board may approve technical or business administration training as acceptable experience, 'but in no case shall the training count as more than one year of experience' (16-77-19), and may accept reasonably equivalent knowledge, training or experience in lieu of a specific experience requirement if upon investigation it makes a detailed finding to that effect (16-77-20). SCOPE, verbatim from the rule: 'Ventilating and air conditioning contractor. To fabricate, assemble, and install warm-air heating and air cooling systems including heating and cooling solar systems, complete ventilating systems and complete air conditioning systems including, but not limited to, piping, controls (other than electrical), instrumentation, building automation, energy management, and trenching, backfilling, patching, and surface restoration in connection with the installation of the air conditioning systems; and including installation of thermal and acoustical insulation necessary to maintain heat, or sound, or both, within the systems above. This also includes the installation of heat pumps related to the air conditioning system' (HAR chapter 16-77, Exhibit A). Note the parenthetical: electrical controls are outside the C-52 scope.	Two written parts, both required. 'All applicants for a contractor's license shall be required to take and successfully pass a written examination designed to test the applicant's general knowledge of the building, safety, health, labor, and lien laws of the State and of the basic administrative principles of the contracting business' (Part I, HAR section 16-77-39), and a second examination 'designed to test the applicant's specialized knowledge in the particular classification in which the applicant desires to be licensed' (Part II, section 16-77-40). 'A grade of seventy-five per cent shall be a minimum passing grade for each part of any examination' (section 16-77-44). An examination is not required 'when the applicant has previously qualified by written examination within a period of four years prior to application, or within four years from the date the applicant was last licensed in good standing or in an inactive status, provided the applicant applies for a license in the same classification in which the applicant previously qualified by examination' (section 16-77-41). Applicants who fail may schedule a second examination and pay the appropriate fees; 'Applicants who fail to pass the examination within six months shall file a new application and application fee' (section 16-77-45). Examinations are given monthly (section 16-77-43) and are administered by the board's testing agency, Prometric.	Per the board's published fee figures: a $50.00 non-refundable application fee accompanies each application (the current application forms state 'The required $50.00 application fee must be attached and submitted with this application form'), and the examination fee is $75.00 per part, paid directly to the testing agency - Hawaii Revised Statutes section 444-12(b) provides that 'Every applicant who is required by the board to be examined shall pay, directly to the testing agency, an examination fee.' License fees become due only after the examination is passed, and differ for a contracting entity or sole proprietor versus a responsible managing employee (see the fees field). Fee amounts are set by rules adopted by the director under HAR chapter 16-53 (HAR sections 16-77-12 and 16-77-54).
Contracting entity license (corporation, partnership, joint venture, LLC or LLP) - qualified through an RME	The entity itself does not hold experience; it qualifies through its responsible managing employee, who must meet the four-year supervisory experience requirement in the C-52 classification (HAR section 16-77-18(c)). The board's own guidance states that an applicant may apply either as a sole proprietor or an entity, and that an entity applicant must also complete a responsible managing employee application, with both the entity and the RME paying separate fees in order to be licensed. A licensee may be classified in more than one classification on meeting the board's qualifications for the additional classification, paying the appropriate application fee but no additional license fee (HRS section 444-8(b)); an additional classification requires filing an application, paying the appropriate fees, meeting the experience requirements for the classification requested, and passing the appropriate Part II examination (HAR section 16-77-35(a)).	The examinations are taken by the RME, not by the entity. Both Part I (business and law) and Part II (trade) apply, at a minimum passing grade of seventy-five per cent for each part (HAR sections 16-77-39, 16-77-40, 16-77-44).	$50.00 application fee per application. On passing, the entity's license fee is billed from the board's fee codes: license $260.00, one-half renewal $95.00, recovery fund $150.00, education fund $10.00, and compliance resolution fund fee (form code 117, printed 'CRF') of $74.00 or $148.00 depending on where in the biennium the license is issued (current application form CT-01, revision 10.25). The board's published totals for a contracting entity or sole proprietor are $663.00 if licensed between October 1 of the even-numbered year and September 30 of the odd-numbered year, and $494.00 if licensed between October 1 of the odd-numbered year and September 30 of the even-numbered year. A $25.00 service charge applies to a dishonored payment.
RME - Responsible Managing Employee (the individual who qualifies the license)	The RME is the individual on whom the entity's or sole proprietor's qualification rests, and must have not less than four years of supervisory experience as a foreman, supervising employee, or contractor in the C-52 classification within the past ten years immediately preceding the filing of the application (HAR section 16-77-18(a), (c)). The board states that HAR section 16-77-71 requires the principal RME to be in residence in Hawaii during the time the license of the contracting entity is in effect or during the period a project is under construction. An individual may serve as RME for more than one contracting entity only upon board approval and only where one of the board's stated relationships exists: common ownership of at least fifty-one per cent of the equity of each entity; one entity being a subsidiary or joint venture of the other; a direct immediate family relationship between the RME and the officers, directors or members of the other contracting entities; or a direct immediate family relationship between the officers, directors or members of all the contracting entities. The board must be notified on the death, dissociation or disability of an RME, and the license is subject to forfeiture (HAR section 16-77-64).	The RME sits the examinations for the entity: Part I on the State's building, safety, health, labor and lien laws and basic administrative principles of the contracting business, and Part II on specialized knowledge in the classification, each at a minimum passing grade of seventy-five per cent (HAR sections 16-77-39, 16-77-40, 16-77-44). Requests to take the licensing examination out of state, and requests to use an interpreter, must be approved by the board; the interpreter service carries a $100.00 fee added to the examination fee, and the applicant is responsible for any additional cost of out-of-state testing.	$50.00 application fee. On passing, the RME's own license fee is billed from the board's fee codes: license $260.00, compliance resolution fund fee (form code 117, printed 'CRF') of $74.00 or $148.00, and one-half renewal $30.00 (current application form CT-35, revision 10.25). The board's published totals for an RME are $438.00 if licensed between October 1 of the even-numbered year and September 30 of the odd-numbered year, and $334.00 if licensed between October 1 of the odd-numbered year and September 30 of the even-numbered year. A separate application and separate fees are required for each contracting entity and each RME.
Sole proprietor license (an individual contracting in his or her own name)	A sole proprietor is the qualifying individual and must personally meet the four-year supervisory experience requirement in the C-52 classification within the past ten years (HAR section 16-77-18(a)). The board's guidance treats the sole proprietor as the qualifying individual in place of an RME.	The same Part I and Part II written examinations at a minimum passing grade of seventy-five per cent for each part (HAR sections 16-77-39, 16-77-40, 16-77-44). The board states that once an application is approved, the qualifying individual - responsible managing employee or sole proprietor - must successfully complete the appropriate licensing examinations within six months.	$50.00 application fee, then the same license-fee schedule as a contracting entity: the board's published totals are $663.00 or $494.00 depending on where in the biennium the license is issued, with a renewal fee of $353.00. Sole proprietors, like business entities, must submit a current state tax clearance with the renewal application.
No separate Hawaii credential for the individual HVAC worker	Hawaii issues no state journeyman, technician or mechanic credential for HVAC work, so there is no individual experience requirement for an employed technician. Two provisions establish this together. HRS section 444-2(6) exempts from the chapter 'Any person who engages in the activities regulated in this chapter as an employee with wages as the person's sole compensation,' so an employed HVAC worker is outside the contractor licensing chapter entirely. And where Hawaii does license individual tradespeople, it says so expressly and only for two trades: HRS section 444-9.5 requires an electrical or plumbing contractor whose responsible managing employee is not licensed under chapter 448E to employ individuals licensed under chapter 448E to actually perform the electrical or plumbing work, and requires that at least half of all individuals performing electrical or plumbing work on a construction job site be licensed under chapter 448E. There is no parallel provision for ventilating and air conditioning work.	None. The examinations attach to the contractor license, taken by the sole proprietor or the responsible managing employee.	None payable to the board by an employed HVAC technician, because no individual HVAC credential is issued. Note that EPA Section 608 refrigerant certification is a separate federal requirement carried by the individual technician.

Who does NOT need this license — exemptions

Hawaii’s carve-outs are spread across more than the section titled ‘Exemptions,’ so all of the chapter’s applicability and limitation provisions are given here. THE MAIN EXEMPTION SECTION. HRS section 444-2 provides that ‘This chapter shall not apply to: (1) Officers and employees of the United States, the State, or any county while in the performance of their governmental duties; (2) Any person acting as a receiver, trustee in bankruptcy, personal representative, or any other person acting under any order or authorization of any court; (3) A person who sells or installs any finished products, materials, or articles of merchandise that are not actually fabricated into and do not become a permanent fixed part of the structure, or to the construction, alteration, improvement, or repair of personal property; (4) Any project or operation for which the aggregate contract price for labor and materials is not more than $1,500. This exemption shall not apply in any case where a building permit is required regardless of the aggregate contract price, nor where the undertaking is only a part of a larger or major project or operation, whether undertaken by the same or a different contractor or in which a division of the project or operation is made in contracts of amounts not more than $1,500 for the purpose of evading this chapter or otherwise; (5) A registered architect or professional engineer acting solely in the person’s professional capacity; (6) Any person who engages in the activities regulated in this chapter as an employee with wages as the person’s sole compensation; (7) Owner-builders exempted under section 444-2.5; (8) Any joint venture if all members thereof hold licenses issued under this chapter; (9) Any project or operation where it is determined by the board that less than ten persons are qualified to perform the work in question and that the work does not pose a potential danger to public health, safety, and welfare; or (10) Any public works project that requires additional qualifications beyond those established by the licensing law and which is deemed necessary and in the public interest by the contracting agency.’ Two of these carry the most weight for HVAC. Paragraph (6) is what makes Hawaii a contractor-licensing state rather than a technician-licensing one: an employed HVAC worker taking wages as sole compensation is outside the chapter. Paragraph (4) is the small-project exemption, and its second and third sentences are the operative limits - a building permit requirement defeats it at any contract price, and it does not reach work that is part of a larger or major project or that has been split into sub-$1,500 contracts. A CONFLICT ON THE SMALL-PROJECT FIGURE, stated rather than resolved: the statute reads $1,500, and its amendment history records an amendment by Act 283 of the 2019 session laws; the board’s own Contractor Frequently Asked Questions, a document self-dated 7/9/18, still answers the handyman question with ‘A license is not required if the aggregate contract price for the project, including labor, materials, taxes, and all other items, is not more than $1,000.00 and does not require a building permit. This exemption does not apply to electrical or plumbing work requiring a permit. Furthermore, even if an electrical or plumbing permit is not required by the county on a particular project, the work may still have to be performed by a licensed electrician or plumber.’ Both figures are published by official Hawaii sources; the statutory text is the higher and later of the two. Confirm with the board before relying on either. THE OWNER-BUILDER EXEMPTION, a separate section. HRS section 444-2.5(a) provides that ‘This chapter shall not apply to owners or lessees of property who build or improve residential or farm buildings or structures on property for their own use, or for use by their grandparents, parents, siblings, or children, and who do not offer the buildings or structures for sale or lease; provided that: (1) To qualify for an exemption under this section, the owner or lessee shall register for the exemption as provided in section 444-9.1; (2) The exemption under this section shall not apply to electrical or plumbing work that must be performed only by persons or entities licensed in accordance with this chapter, unless the owner or lessee of the property is licensed for such work under chapter 448E; (3) An owner or lessee exempted under this section shall: (A) Supervise the construction activity on the exempt buildings or structures; (B) Hire subcontractors appropriately licensed under this chapter to perform any part of the construction activity for which a license is required; (C) Ensure that any electrical or plumbing work is performed by persons and entities appropriately licensed under this chapter or chapter 448E; (D) Deduct Federal Insurance Contributions Act and withholding taxes and provide workers’ compensation insurance for persons working on the construction activity who are not licensed under this chapter or chapter 448E and who shall be considered employees of the owner or lessee; and (E) Ensure that the construction activity complies with all applicable laws, ordinances, building codes, and zoning regulations,’ followed by record-keeping duties during construction and for three years after completion. Subsection (b) adds a presumption with its own carve-outs: ‘Proof of the sale or lease, or offering for sale or lease, of the structure within one year after completion shall be prima facie evidence that the construction or improvement of the structure was undertaken for the purpose of sale or lease; provided that this subsection shall not apply to: (1) Residential properties sold or leased to employees of the owner or lessee; (2) Construction or improvements performed pursuant to an approved building permit where the estimated valuation of work to be performed, as reflected in the building permit, is less than $10,000; or (3) Any sale or lease caused by an eligible unforeseen hardship as determined by the board pursuant to subsection (c).’ Note the practical point for an HVAC contractor: an owner-builder must still hire appropriately licensed subcontractors for work requiring a license. LIMITS THAT FUNCTION AS SCOPE RESTRICTIONS RATHER THAN EXEMPTIONS. HRS section 444-8(c) provides that the section ‘shall not prohibit a specialty contractor from taking and executing a contract involving the use of two or more crafts or trades, if the performance of the work in the crafts or trades, other than in which the specialty contractor is licensed, is incidental and supplemental to the performance of work in the craft for which the specialty contractor is licensed,’ and HAR section 16-77-34 defines the term as ‘work in other trades directly related to and necessary for the completion of the project undertaken by a licensee pursuant to the scope of the licensee’s license.’ Against that, HAR section 16-77-33(c) provides that ‘A licensee classified as a specialty contractor shall not act, assume to act, or advertise as a contractor in any classification other than those which the licensee holds,’ and section 16-77-33(b) provides that a general building contractor license does not entitle the holder to undertake a contract unless it requires more than two unrelated building trades or crafts, or unless the general building contractor holds the specialty license to undertake the contract. HAR section 16-77-32(d) provides that licensees holding a specialty contractors license automatically hold the subclassifications of their particular specialty without examination or paying additional fees. Finally, the C-52 scope itself excludes electrical controls - the rule reads ‘controls (other than electrical)’ - and under HRS section 444-9.5 electrical and plumbing work is reserved to individuals licensed under chapter 448E in the circumstances that section sets out, with an exemption within that section for employees of a community antennae television company and employees of a state-franchised or chartered public utility regulated by the public utilities commission while so employed and acting within the scope of their employment.

Fees

Hawaii’s contractor fees are set by rules adopted by the director under HAR chapter 16-53, which HAR sections 16-77-12 and 16-77-54 point to for application and renewal amounts respectively. The dollar figures below come from the board’s own published materials and reconcile exactly between them. APPLICATION: $50.00 non-refundable per application - ‘The required $50.00 application fee must be attached and submitted with this application form’ (current application forms CT-01 for an entity and CT-35 for an RME, revision 10.25) - and the board notes you may apply for more than one classification per application, but a separate application is required for each contracting entity and each RME. An application fee does not carry over to a later application. Every application is also accompanied by a contractors education fund fee of ten dollars (HAR section 16-77-12(a)). EXAMINATION: $75.00 per part, paid directly to the testing agency (HRS section 444-12(b)); most classifications require both Part I (business and law) and Part II (trade). An interpreter, if approved by the board, adds $100.00 to the examination fee. INITIAL LICENSE, billed after the examination is passed. The board’s published totals are: contracting entity or sole proprietor - $663.00 if licensed between October 1 of the even-numbered year and September 30 of the odd-numbered year, and $494.00 if licensed between October 1 of the odd-numbered year and September 30 of the even-numbered year; responsible managing employee - $438.00 and $334.00 on the same two-part split. The current application forms itemize the components behind those totals: for an entity, license $260.00, one-half renewal $95.00, recovery fund $150.00, education fund $10.00, and compliance resolution fund fee (form code 117, printed ‘CRF’) of $74.00 or $148.00; for an RME, license $260.00, compliance resolution fund fee (form code 117, printed ‘CRF’) of $74.00 or $148.00, and one-half renewal $30.00. RENEWAL: the board publishes $353.00 for a contracting entity or sole proprietor and $208.00 for a responsible managing employee, due on or before September 30 of each even-numbered year, plus a contractors education fund fee of five dollars and a contractors recovery fund fee of ten dollars (HAR section 16-77-54). A late restoration within the statutory window carries a penalty fee. OTHER CHARGES: a $25.00 service charge applies if a payment is dishonored, and the dishonoring of any check upon first deposit constitutes a failure to meet the fee requirements (HRS section 444-15(d); HAR section 16-77-12(b)). The board may also assess a fee not to exceed $1,000 as a condition of restoring a license forfeited for lapsed insurance or bond (HRS section 444-11.1(e)). Beyond board fees, budget for workers’ compensation insurance, comprehensive personal injury and property damage liability insurance at the renewal minimums, any surety bond the board imposes (not less than $5,000 for a specialty contractor), a state tax clearance, business registration where applicable, and - for refrigerant work - EPA Section 608 certification, which is a separate federal credential. Because the amounts are set by rule and can be revised, confirm the current figures with the board before applying.

Exam

Hawaii examines the individual who qualifies the license - the sole proprietor or the responsible managing employee - not each HVAC worker, and the examination has two parts, both required. Part I is ‘a written examination designed to test the applicant’s general knowledge of the building, safety, health, labor, and lien laws of the State and of the basic administrative principles of the contracting business’ (HAR section 16-77-39). Part II is ‘a written examination designed to test the applicant’s specialized knowledge in the particular classification in which the applicant desires to be licensed’ (section 16-77-40) - for HVAC, the C-52 ventilating and air conditioning trade examination. ‘A grade of seventy-five per cent shall be a minimum passing grade for each part of any examination’ (section 16-77-44). Examinations are administered by the board’s testing agency, Prometric, which also supplies the Bulletin of Examination Information and recommended study materials; applicants whose applications have been approved are given an application for examination and apply to the testing agency, and examinations are given monthly (section 16-77-43). The examination fee is paid directly to the testing agency (HRS section 444-12(b)) and the board publishes it as $75.00 per part, with most classifications requiring both parts. An applicant who fails may schedule a second examination and pay the appropriate fees, but ‘Applicants who fail to pass the examination within six months shall file a new application and application fee’ (section 16-77-45). An examination is not required ‘when the applicant has previously qualified by written examination within a period of four years prior to application, or within four years from the date the applicant was last licensed in good standing or in an inactive status, provided the applicant applies for a license in the same classification in which the applicant previously qualified by examination’ (section 16-77-41). Requests to sit the examination out of state and requests to use an interpreter must both be approved by the board; the interpreter must not currently be and must not have been in the construction business, and the service carries a $100.00 fee added to the examination fee (section 16-77-42; current application forms). Examination misconduct - including unauthorized communication, use of unauthorized materials, or having another person sit the examination - may result in the entire examination being invalidated and the applicant being suspended from testing for up to three years (section 16-77-46). A licensee seeking an additional classification files an application, pays the appropriate fees, meets the experience requirement for the classification requested, and passes the appropriate Part II examination (section 16-77-35(a)).

Renewal & continuing education

Biennial, on a fixed statewide date rather than a licence anniversary: all contractor licenses expire on September 30 of the even-numbered year. ‘The biennial renewal fee or inactive license fee, and the recovery fund, education fund, and compliance resolution fund fees shall be paid to the board on or before September 30 of each even-numbered year … Failure, neglect, or refusal of any licensee to pay these fees and to submit all documents required by the board on or before September 30 of each even-numbered year shall constitute a forfeiture of the licensee’s license’ (HRS section 444-15(a)). The board mails renewal applications to all current licensees before August 15 of the even-numbered year, but the duty to renew does not depend on receiving one. Business entities and sole proprietors must submit a current state tax clearance from the State Department of Taxation with the renewal application, and the board may accept a letter from that department confirming a tax payment arrangement in lieu of the tax clearance; verification of current liability and workers’ compensation insurance may be required if the insurance expires prior to September 30; responsible managing employees are not required to submit insurance information or a tax clearance unless required to verify payment of past due taxes or liens. Renewal is also conditioned on continuing to meet HRS sections 444-11, 444-11.1 and 444-17 and on proof of financial integrity (HAR section 16-77-55). If the license is not renewed by the deadline it is forfeited: ‘Any forfeited license may be restored upon submittal of all required documents and fees, plus a penalty fee, within sixty days from September 30 of the even-numbered year’ (HRS section 444-15(b)), and by rule restoration runs ‘on or before November 30 of the renewal year’, after which a licensee ‘shall be required to apply as new applicants’ (HAR section 16-77-51; the board’s current forms state the same date). A licensee may instead request inactive status, paying the inactive license fee, continuing inactive for the biennial period, and not engaging in contracting during it; the license may be reactivated at any time during the biennial period by written request (HRS section 444-15(c)); under HAR section 16-77-56 the reactivation submission is an application, application fee, current financial statement, tax clearance, and credit report, reviewed by the board as if it were a new application. Hawaii’s Contractors License Board does not list continuing education among its conditions for renewing a contractor license. HAR section 16-77-55 provides that no license shall be renewed until the licensee continues to meet the requirements of HRS sections 444-11, 444-11.1 and 444-17 and of the rules chapter, ‘including, but not limited to, proof of financial integrity,’ and then enumerates what the licensee must submit to establish that: a current state tax clearance or proof of a payment arrangement together with a statement disclosing or denying the existence of any liens, undisputed debts or judgments relating to services or materials rendered in connection with operations as a contractor; proof that the licensee has continuously maintained workers’ compensation insurance, is authorized to act as a self-insurer under HRS chapter 386, or is excluded from that chapter’s requirements; proof that liability and property damage insurance has been maintained at bodily injury limits of $100,000 each person and $300,000 each occurrence and property damage limits of $50,000 each occurrence; and proof that any surety bond imposed by the board is current. The board’s own renewal guidance describes the same set of documents and fees. No continuing-education hour requirement appears in those renewal conditions or in the board’s published renewal guidance. Because renewal requirements are set by rule and can change, confirm the current conditions with the board ahead of the September 30 biennial deadline. Separately, EPA Section 608 refrigerant certification is a federal credential and carries its own federal rules, not Hawaii continuing education.

Frequently asked questions

Does Hawaii require an HVAC license?

Yes - at the contractor level. Hawaii licenses ventilating and air conditioning work through the Contractors License Board as the C-52 specialty contractor classification under HRS chapter 444 and the board’s rules in HAR chapter 16-77, and ‘No person within the purview of this chapter shall act, or assume to act, or advertise, as general engineering contractor, general building contractor, or specialty contractor without a license’ (HRS section 444-9). But Hawaii licenses the contracting business, not each technician: the chapter does not apply to ‘Any person who engages in the activities regulated in this chapter as an employee with wages as the person’s sole compensation’ (section 444-2(6)), so an employed HVAC worker needs no state credential of their own. There is no Hawaii journeyman, technician or mechanic license for HVAC.

What exactly does a C-52 license let you do?

The rules define the scope as: ‘To fabricate, assemble, and install warm-air heating and air cooling systems including heating and cooling solar systems, complete ventilating systems and complete air conditioning systems including, but not limited to, piping, controls (other than electrical), instrumentation, building automation, energy management, and trenching, backfilling, patching, and surface restoration in connection with the installation of the air conditioning systems; and including installation of thermal and acoustical insulation necessary to maintain heat, or sound, or both, within the systems above. This also includes the installation of heat pumps related to the air conditioning system.’ Note the parenthetical - electrical controls sit outside the C-52 scope. A specialty contractor may take a contract involving other trades only where that work is ‘incidental and supplemental’ to the licensed craft (HRS section 444-8(c)), meaning work in other trades directly related to and necessary for completing the project (HAR section 16-77-34).

What experience and exams does Hawaii require?

Four years of supervisory experience: ‘Every individual applicant or RME shall have had, within the past ten years immediately preceding the filing of an application, not less than four years of supervisory experience as a foreman, supervising employee, or contractor in the particular classification in which the applicant intends to engage as a contractor’ (HAR section 16-77-18(a)). Approved technical or business administration training may count, but never as more than one year of experience. The qualifying individual - a sole proprietor, or an entity’s responsible managing employee - must then pass two written examinations: Part I on the State’s building, safety, health, labor and lien laws and basic administrative principles of the contracting business, and Part II on specialized knowledge in the classification. A grade of seventy-five per cent is the minimum passing grade for each part. Examinations are administered by Prometric and given monthly, and an applicant who does not pass within six months must file a new application and application fee.

How much does a Hawaii C-52 license cost?

A $50.00 non-refundable application fee accompanies each application, and the examination fee is $75.00 per part, paid directly to the testing agency. License fees are billed after the examination is passed and depend on where in the two-year cycle the license is issued: the board publishes $663.00 for a contracting entity or sole proprietor licensed between October 1 of the even-numbered year and September 30 of the odd-numbered year, and $494.00 for one licensed in the following twelve months; for a responsible managing employee the figures are $438.00 and $334.00. Renewal is $353.00 for a contracting entity or sole proprietor and $208.00 for a responsible managing employee. Fee amounts are set by rule and can be revised, so confirm the current figures with the board. Budget separately for workers’ compensation and liability insurance, any bond the board imposes, and a state tax clearance.

When does a Hawaii contractor license renew?

On a fixed statewide date, not a licence anniversary: every contractor license expires on September 30 of the even-numbered year, and renewal fees plus all required documents are due on or before that date (HRS section 444-15(a)). The board mails renewal applications to current licensees before August 15 of the even-numbered year, but the duty to renew does not depend on receiving one. Business entities and sole proprietors submit a current state tax clearance with the renewal. Miss the deadline and the license is forfeited, though it may be restored on submitting all required documents and fees plus a penalty fee within sixty days from September 30 - the rule and the board’s forms give that outside date as November 30 of the renewal year, after which applying as a new applicant is required (HAR section 16-77-51). Continuing education is not among the board’s stated renewal conditions.

Is there a small-job exemption, and does Hawaii have reciprocity?

There is a small-project exemption, and it is narrower than it looks. HRS section 444-2(4) exempts ‘Any project or operation for which the aggregate contract price for labor and materials is not more than $1,500,’ but the same paragraph continues: ‘This exemption shall not apply in any case where a building permit is required regardless of the aggregate contract price, nor where the undertaking is only a part of a larger or major project or operation, whether undertaken by the same or a different contractor or in which a division of the project or operation is made in contracts of amounts not more than $1,500 for the purpose of evading this chapter or otherwise.’ The board’s frequently asked questions still describe this exemption using a $1,000 figure; the statute as amended reads $1,500. On reciprocity, the board’s answer is plain: ‘No. All applicants must meet the same licensing and examination requirements.’ Separately, EPA Section 608 refrigerant certification is a federal requirement held by the individual technician and is not a Hawaii license.
