Haw. Rev. Stat. § 205-4.5
(a) Within the agricultural district, all lands with soil classified by the land study bureau's detailed land classification as overall (master) productivity rating class A or B and for solar energy facilities, class B or C, shall be restricted to the following permitted uses:
(12) Plantation community subdivisions, which as used in this chapter means an established subdivision or cluster of employee housing, community buildings, and agricultural support buildings on land currently or formerly owned, leased, or operated by a sugar or pineapple plantation; provided that the existing structures may be used or rehabilitated for use, and new employee housing and agricultural support buildings may be allowed on land within the subdivision as follows:
(16) Biofuel processing facilities, including the appurtenances associated with the production and refining of biofuels that is normally considered directly accessory and secondary to the growing of the energy feedstock; provided that biofuel processing facilities and appurtenances do not adversely impact agricultural land and other agricultural uses in the vicinity.
For the purposes of this paragraph:
"Appurtenances" means operational infrastructure of the appropriate type and scale for economic commercial storage and distribution, and other similar handling of feedstock, fuels, and other products of biofuel processing facilities.
"Biofuel processing facility" means a facility that produces liquid or gaseous fuels from organic sources such as biomass crops, agricultural residues, and oil crops, including palm, canola, soybean, and waste cooking oils; grease; food wastes; and animal residues and wastes that can be used to generate energy;
(17) Agricultural-energy facilities, including appurtenances necessary for an agricultural-energy enterprise; provided that the primary activity of the agricultural-energy enterprise is agricultural activity. To be considered the primary activity of an agricultural-energy enterprise, the total acreage devoted to agricultural activity shall be no less than ninety per cent of the total acreage of the agricultural-energy enterprise. The agricultural-energy facility shall be limited to lands owned, leased, licensed, or operated by the entity conducting the agricultural activity.
As used in this paragraph:
"Agricultural activity" means any activity described in paragraphs (1) to (3) of this subsection.
"Agricultural-energy enterprise" means an enterprise that integrally incorporates an agricultural activity with an agricultural-energy facility.
"Agricultural-energy facility" means a facility that generates, stores, or distributes renewable energy as defined in section 269-91 or renewable fuel including electrical or thermal energy or liquid or gaseous fuels from products of agricultural activities from agricultural lands located in the State.
"Appurtenances" means operational infrastructure of the appropriate type and scale for the economic commercial generation, storage, distribution, and other similar handling of energy, including equipment, feedstock, fuels, and other products of agricultural-energy facilities;
(21) Solar energy facilities on lands with soil classified by the land study bureau's detailed land classification as overall (master) productivity rating B or C for which a special use permit is granted pursuant to section 205-6; provided that:
(ii) Restoration of the disturbed earth to substantially the same physical condition as existed before the development of the solar energy facility.
For the purposes of this paragraph, "agricultural activities" means the activities described in paragraphs (1) to (3);
(23) Hydroelectric facilities, including the appurtenances associated with the production and transmission of hydroelectric energy, subject to section 205-2; provided that the hydroelectric facilities and their appurtenances:
(b) Uses not expressly permitted in subsection (a), including landfill units, as defined in section 342H-52, located on land within the agricultural district that has soil classified by the land study bureau's detailed land classification as overall (master) productivity rating class A in a county with a population greater than five hundred thousand, shall be prohibited, except the uses permitted as provided in sections 205-6 and 205-8, and construction of single-family dwellings on lots existing before June 4, 1976. Any other law to the contrary notwithstanding, no subdivision of land within the agricultural district with soil classified by the land study bureau's detailed land classification as overall (master) productivity rating class A or B shall be approved by a county unless those A and B lands within the subdivision are made subject to the restriction on uses as prescribed in this section and to the condition that the uses shall be primarily in pursuit of an agricultural activity.
Any deed, lease, agreement of sale, mortgage, or other instrument of conveyance covering any land within the agricultural subdivision shall expressly contain the restriction on uses and the condition, as prescribed in this section, that these restrictions and conditions shall be encumbrances running with the land until the land is reclassified to a land use district other than an agricultural district.
If the foregoing requirement of encumbrances running with the land jeopardizes the owner or lessee in obtaining mortgage financing from any of the mortgage lending agencies set forth in the following paragraph, and the requirement is the sole reason for failure to obtain mortgage financing, then the requirement of encumbrances shall, insofar as the mortgage financing is jeopardized, be conditionally waived by the appropriate county enforcement officer; provided that the conditional waiver shall become effective only in the event that the property is subjected to foreclosure proceedings by the mortgage lender.
The mortgage lending agencies referred to in the preceding paragraph are the Federal Housing Administration, Federal National Mortgage Association, Department of Veterans Affairs, Small Business Administration, United States Department of Agriculture, Federal Land Bank of Berkeley, Federal Intermediate Credit Bank of Berkeley, Berkeley Bank for Cooperatives, and any other federal, state, or private mortgage lending agency qualified to do business in Hawaii, and their respective successors and assigns.
(f) Notwithstanding any other law to the contrary, agricultural lands may be subdivided and leased for the agricultural uses or activities permitted in subsection (a); provided that:
(3) The lease term for a subdivided lot shall be for at least as long as the greater of:
(B) Five years.
Lots created and leased pursuant to this section shall be legal lots of record for mortgage lending purposes and shall be exempt from county subdivision standards.

Religious Land Use and Institutionalized Persons Act of 2000 (RLUIPA), assuming it was constitutional, did not facially invalidate Hawaii's land use law, where plaintiffs challenged this section and §205-6 to the extent the sections required a religious organization to obtain a special use permit, as violations of the "equal terms" and "nondiscrimination" provisions of the RLUIPA. 229 F. Supp. 2d 1056 (2002).
"Communications equipment buildings" and "utility lines" in subsection (a)(7) do not encompass "telecommunications antennas" or "transmission antennas" such as a cellular telephone tower; public utility thus had to apply for a special permit under §205-6 to place the tower in a state agricultural district. 90 H. 384, 978 P.2d 822 (1999).
Under subsection (a)(4) and (10), a chimney and garage are permitted as accessories to a farm dwelling; however, utilizing the chimney to conceal an antenna and the garage to house communication equipment were not permitted uses under either subsection (a)(4) or (10). 106 H. 343, 104 P.3d 930 (2005).
Under the circumstances of the case, the residence and the chimney with the concealed antenna constituted a "communications equipment building" and, thus, were permitted uses under subsection (a)(7); also, as the garage was not abnormally large and was designed specifically to store the communications equipment for the concealed antenna, utilizing the permitted garage structure to house the communications equipment for the antenna was a permitted use under subsection (a)(7). 106 H. 343, 104 P.3d 930 (2005).
