Hawaii Executive Departments: Full List and Agency Functions

Hawaii's executive branch is organized into 18 principal departments established under Article V of the Hawaii State Constitution, each headed by a director appointed by and serving at the pleasure of the Governor. These departments carry out the administrative, regulatory, and service functions of state government across all four counties. Understanding the structure, jurisdictional scope, and functional mandates of each department is essential for residents, contractors, legal professionals, and researchers interacting with state agencies.

Definition and scope

Hawaii's executive departments are constitutionally and statutorily defined administrative units of state government. Under Hawaii Revised Statutes (HRS) §26-4, the principal departments of the executive branch are enumerated, and each operates under enabling legislation that defines its authority, functions, and organizational structure.

The 18 principal departments are:

1. Department of Accounting and General Services (DAGS) — manages state accounting, public works, central services, and state archives
2. Department of Agriculture (HDOA) — regulates agricultural practices, plant and pest quarantine, and food safety (profile)
3. Department of the Attorney General (DOJ-HI) — provides legal counsel to state government, enforces state law, and manages criminal prosecutions (profile)
4. Department of Budget and Finance (B&F) — oversees the state budget process, debt management, and employee retirement systems
5. Department of Business, Economic Development, and Tourism (DBEDT) — coordinates economic policy, strategic planning, and tourism oversight
6. Department of Commerce and Consumer Affairs (DCCA) — licenses professions, regulates financial institutions, and enforces consumer protection laws (profile)
7. Department of Defense (HI DOD) — administers the Hawaii National Guard, civil defense readiness, and emergency management operations (profile)
8. Department of Education (DOE) — operates the single statewide public school system covering all K–12 education (profile)
9. Department of Health (DOH) — administers public health programs, environmental health regulation, and behavioral health services (profile)
10. Department of Human Resources Development (DHRD) — manages state workforce policy, civil service classification, and collective bargaining support
11. Department of Human Services (DHS) — administers benefit programs including Medicaid (Med-QUEST), SNAP, and child welfare services (profile)
12. Department of Labor and Industrial Relations (DLIR) — enforces labor standards, manages unemployment insurance, and oversees workers' compensation (profile)
13. Department of Land and Natural Resources (DLNR) — manages state land, conservation districts, water resources, and historic preservation (profile)
14. Department of Taxation (DOTAX) — administers Hawaii's tax laws including the general excise tax and income tax (profile)
15. Department of Transportation (HDOT) — manages highways, harbors, and airports statewide (profile)
16. Office of the Governor — executive leadership and policy direction (profile)
17. Office of the Lieutenant Governor — election administration and statutory functions (profile)
18. Department of Hawaiian Home Lands (DHHL) — administers homestead land leases under the Hawaiian Homes Commission Act of 1920

The Governor's authority to appoint department directors is governed by HRS §26-34, with the Senate confirming most appointments.

How it works

Each principal department operates under a director who functions as the chief executive officer of that department. Directors report directly to the Governor and are accountable to the Governor's Office for policy implementation. Deputy directors and division chiefs manage sub-units within departments.

Departments are funded through the annual state operating budget, which originates with the Department of Budget and Finance and is enacted by the Hawaii State Legislature. Capital improvement appropriations and federal fund allocations supplement general fund revenues. The Hawaii General Excise Tax — set at a base rate of 4% under HRS §237-13 — constitutes a primary source of state revenue flowing to department budgets (Hawaii Department of Taxation).

Departmental rulemaking follows the Hawaii Administrative Procedure Act (HRS Chapter 91), which requires public notice, comment periods, and formal hearings before rules take effect. The Hawaii Ethics Commission maintains jurisdiction over conduct standards for executive branch employees across all departments.

The contrast between line departments and staff departments is structurally significant. Line departments (DOT, DOH, DOE, DHS) deliver direct services to the public. Staff departments (DHRD, DAGS, B&F) provide internal services to other executive agencies. This distinction affects budget structures, headcount, and legislative oversight mechanisms.

Common scenarios

Several operational patterns characterize how departments interact with the public and with each other:

• Licensing and permitting: DCCA handles approximately 30 professional licensing boards, each with distinct examination, fee, and renewal requirements established under HRS Title 25.
• Land use determinations: DLNR administers the Conservation District under HRS Chapter 183C; contested cases go to the Board of Land and Natural Resources before judicial review.
• Environmental enforcement: DOH's Environmental Health Administration enforces Clean Air Act and Clean Water Act programs under delegated federal authority from the U.S. Environmental Protection Agency (EPA delegation).
• Tax compliance: DOTAX administers the GET across all islands with no county-level counterpart, a structure unique among U.S. states.
• Education administration: DOE operates as a single statewide district — the only such structure among the 50 states — with one school board and one superintendent governing all public schools.

Decision boundaries

This page covers the 18 principal executive departments of the State of Hawaii as defined under HRS §26-4 and the Hawaii State Constitution. Scope limitations include:

• Not covered: Hawaii's 4 county governments (Honolulu, Maui, Hawaii, Kauai), which operate independent executive structures under county charters. See Hawaii County Government Structure.
• Not covered: The Hawaii State Legislature and its staff agencies, which fall under the legislative branch and are addressed separately at Hawaii State Legislature.
• Not covered: The Hawaii Judiciary, including the Hawaii Supreme Court and lower courts, which constitute a co-equal but separate branch.
• Not covered: Federal agencies operating in Hawaii (U.S. Department of Defense installations, federal courts, federal land management agencies). The relationship between state and federal authority is addressed at Hawaii Federal Government Relationship.
• Not covered: Semi-autonomous boards and commissions that operate alongside departments (e.g., the Board of Education, University of Hawaii Board of Regents) but are not classified as principal departments under HRS §26-4.

The Office of Hawaiian Affairs is a state agency established under Article XII of the Hawaii Constitution but operates with a degree of independence not characteristic of the 18 principal departments. It is not classified as an executive department under HRS §26-4.
