Act 204 revolving loan fund (2026)

Governor Green signed Act 204 in 2026, creating a Cesspool Conversion Revolving Loan Fund to be administered by the Hawaiʻi Green Infrastructure Authority (HGIA). Public reporting described the program as a path toward low-interest or forgivable loans for eligible households, with program details still under development.

Do not assume eligibility, rates, or application timing until HGIA publishes current rules.
County and island context still affect contractor availability and total project cost.
Keep engineering, permit, construction, and restoration quotes even if assistance is pursued.

Avoid preventable surprises
