Summary

Hawaii uniquely splits zoning/land-use authority between the state and its counties. At the state level, HRS Chapter 205 (the State Land Use Law) creates the Land Use Commission, which under § 205-2 classifies ALL land in the state into four major districts — urban, rural, agricultural, and conservation — a statewide framework no other state has. Below that, HRS § 46-4 delegates traditional zoning power to the counties, authorizing them to exercise the zoning power by ordinance (within their general plans) to regulate the use, height, density, lot size, and setbacks of land. Because Hawaii has no incorporated municipalities — its four counties (Honolulu, Hawaii, Maui, Kauai) are the only general-purpose local governments — county zoning is the sole layer of local zoning, operating within the state's overarching land-use districting. Authority is therefore both state-level (Ch. 205) and county-delegated (§ 46-4); confidence is high, with verbatim language confirmed against the official capitol.hawaii.gov text and the University of Hawaii ohelo statutory mirror.

The delegation

HRS § 46-4 County zoning. (a) This section and any ordinance, rule, or regulation adopted in accordance with this section shall apply to lands not contained within the forest reserve boundaries... Zoning in all counties shall be accomplished within the framework of a long-range, comprehensive general plan prepared or being prepared to guide the overall future development of the county. ... The zoning power granted herein shall be exercised by ordinance which may relate to: [twelve enumerated categories — including the areas within which agriculture, forestry, industry, trade, and business may be conducted; the areas in which residential uses may be regulated; the areas bordering natural watercourses; the maximum heights, areas, and sizes of buildings; minimum lot sizes; setbacks; density; and related land development standards]. ... The powers granted herein shall be liberally construed in favor of the county exercising them, and in such a manner as to promote the orderly development of each county or city and county in accordance with a long-range, comprehensive general plan to ensure the greatest benefit for the State as a whole. HRS § 205-2 Districting and classification of lands. (a) There shall be four major land use districts in which all lands in the State shall be placed: urban, rural, agricultural, and conservation. The land use commission shall group contiguous land areas suitable for inclusion in one of these four major districts.

Verification

Read the verification audit

Verified all three points against multiple sources (official capitol.hawaii.gov URLs surfaced in search, FindLaw, Justia 2025 codes, and a GitHub HRS mirror). (a) Citations are real and current. HRS § 46-4 ("County zoning," Title 6 — County Organization and Administration) exists in the 2025 code and is not repealed. HRS Chapter 205 ("Land Use Commission," Title 13 — Planning and Economic Development) exists with §§ 205-1 (commission/definitions) and 205-2 (districting and classification of lands) present in the 2025 code. (b) Both are genuinely the zoning/land-use enabling authority. § 46-4(a) confirms: "The zoning power granted herein shall be exercised by ordinance" and enumerates regulation of use areas (agriculture, forestry, industry, trade, business, residential), location/height/bulk/stories/size of buildings (item 6), density and distribution of population (item 9), percentage of lot occupied, size of yards/courts/setbacks (item 10), and minimum/maximum lot sizes (item 11) — within "a long-range, comprehensive general plan." This is the county zoning delegation. § 205-2 classifies all lands in the State into four districts — urban, rural, agricultural, conservation — administered by the Land Use Commission (created in Ch. 205), confirming the overarching statewide land-use districting layer. (c) authority_model is accurate. Hawaii uniquely operates a two-tier system: state-level land-use districting (Ch. 205 / Land Use Commission) layered over county-delegated traditional zoning (§ 46-4). The claim that Hawaii has no incorporated municipalities and that its four counties (Honolulu — a consolidated city-and-county, Hawaii, Maui, Kauai) are the only general-purpose local governments is correct; county zoning is the sole local zoning layer. The "state_level + county_delegation" model and exclusion of "county_and_municipal" are correct. Minor note (not affecting verification): § 46-4 phrases part of its definition as zoning "in the counties of Hawaii, Maui, and Kauai" while Honolulu's zoning power flows through the same chapter as a consolidated city-and-county; the broader grant language applies to "all counties," so all four are covered. No correction needed to citation, title, or authority_model.
