A copy, taken August 21, 2026. The version published by Maui County is the one that governs, and it may have changed since. Check it before relying on anything here.
A.
As used in this section, "alternate energy improvement" means any construction or
addition, alteration, modification, improvement, or repair work undertaken upon or
made to any building which results in:
1.
The production of energy from a source, or uses a process which does not use fossil
fuels, nuclear fuels or geothermal source. Such energy source may include but shall
not be limited to solid wastes, wind, solar, or ocean waves, tides, or currents. Alternate
energy production or energy byproducts transferred, marketed, or sold on a commercial
basis shall not qualify for exemption under the provisions of this section. Provided
further, that alternate energy improvements used primarily for personal consumption
and producing excess energy incidental to personal consumption may transfer, market,
or sell such excess energy produced and continue to qualify for the exemption provided
for by the provisions of this section; however, the transfer, marketing, or sale shall
be limited to less than twenty-five percent of the total energy output produced by
such improvements. Nuclear fission and geothermal energy sources shall be excused
from the provisions of this section; or
2.
An increase level of efficiency in the utilization of energy produced by fossil fuels
or in the utilization of secondary forms of energy dependent upon fossil fuels for
its generation.
B.
The value of all improvements in the County (not including a building or its structural
components, except where alternate energy improvements are incorporated into the building
and then only that part of the building necessary to such improvement) actually used
for an alternate energy improvement shall be exempted from the measure of the taxes
imposed by this chapter.
C.
Application for the exemption provided by this section shall be made with the director
of finance on or before December 31st, preceding the tax year for which the exemption
is claimed, except that no claim need be filed for the exemption of solar water collectors,
heaters, heat pumps and similar devices.
D.
The director of finance may require the taxpayer to furnish reasonable information
in order that he may ascertain the validity of the claim for exemption made under
this section and may adopt rules and regulations to implement this section.
