Hawaii licenses contractors by classification: the scope of work your license covers. Pick the wrong classification and you waste months. Here is how the system is organized and how to choose.
This is an independent guide, not affiliated with the Hawaii Department of Commerce and Consumer Affairs, the Contractors License Board, or PSI. Licensing details change, so verify current requirements against the Board's official publications before you act.
The three branches
Hawaii has three license branches under HRS section 444-7:
A: General engineering. Heavy civil work: the kind of projects that move earth, water, and infrastructure. Think highways, bridges, dams, drainage, and utilities.
B: General building. Building construction: residential and commercial structures, from the foundation to the roof.
C: Specialty contracting. Everything else, broken into 96 distinct designations (C-1 through C-68, with lettered subclassifications), covering individual trades: electrical, plumbing, roofing, painting, drywall, HVAC, and dozens more, including the C-68 classified specialist for work that does not fit the other categories.
The A and B exams carry a slightly higher exam fee ($85 instead of $80), which is a small signal of how the Board weights them.
How classifications interact with the exams
The Business and Law exam is the same for everyone: 80 questions, closed book, 75 percent to pass. What changes by classification is Part II of the examination, which tests specialized knowledge in the classification you are seeking. You need 75 percent on each part. Adding a classification later does not require retaking the Business and Law exam.
Your 4 years of supervisory experience must be in the classification requested. Experience as a foreman on residential framing does not automatically qualify you for a general engineering license. Match your documented experience to the classification you apply for.
Choosing the right classification
Match the work you actually plan to do. The Board can limit licenses by field and scope, and working outside your classification is a violation. If your work spans more than one classification, you may need more than one license.
Do not overreach. A general building license does not authorize specialty work outside its scope, and a specialty license does not authorize general building work. The classifications post on the Board's site lists what each designation covers. Read it before you apply.
Consider the joint venture rule. A joint venture or partnership needs no separate license if all members or partners hold current contractor licenses and the work is within a classification held by one of them, but the board must be notified in writing of the venture and its principal RME. If any member or partner is unlicensed, a license is required. All joint ventures and partnerships must register with the business registration division before engaging in contracting.
The handyman question. If your work stays under $1,500 in labor and materials per project, with no building permit required and no project-splitting, the handyman exemption means you may not need a license at all. But the moment you cross that line, or take a job that needs a permit, you need the right classification in hand first.
The RME follows the classification
Your Responsible Managing Employee must have passed the exam in the appropriate classification. An RME qualified in a specialty classification does not cover the entity for general building work. When the RME departs, the 60-day notice and 90-day replacement clock runs against the classification the license carries.
The exam fee difference
The Business and Law exam fee is $80 for most applicants, but A-General Engineering and B-General Building applicants pay $85. It is a small difference, but it signals how the system treats the general classifications: broader scope, slightly higher bar. The specialty exams carry the standard $80 fee.
Experience must match the classification
The 4-years-supervisory-within-10 requirement is classification-specific. Your documented experience must be in the classification requested. Time as a foreman on specialty work does not automatically support a general building application. When the Board reviews your experience, it is checking two things: that you supervised (not just worked), and that the supervision was in the trade the license covers. Board-approved technical or business-administration training can fill at most 1 year of the 4, and it does not change which classification the experience points to.
Joint ventures and classification coverage
The joint venture rule is classification-aware: a venture needs no separate license if all members hold current licenses and the work is within a classification held by one of them. One licensed partner cannot cover work outside every partner's classifications. The venture must notify the board in writing and name its principal RME, register with the business registration division before engaging in contracting, and notify the board of dissolution within 30 days. If any member's license is suspended, revoked, forfeited, or refused renewal, the venture's license forfeits automatically.
Common mistakes
- Applying for A or B when a specialty fits. Broader is not better if your experience and exam preparation are in a trade. The Part II exam tests the classification you chose.
- Assuming one license covers everything. It does not. Scope violations are enforceable.
- Forgetting the RME match. The entity's license is only as broad as its RME's qualification.
Next steps
Once your classification is settled, the path continues: document your experience, prepare for the closed-book exams, and budget the costs. The full sequence is in How to Get a Hawaii Contractor License.
