What it takes to build here — permits, zoning, and septic — scouted from Maui County’s own official sources.
A building permit is required for construction, alteration, moving, demolition, repair and use of any building or structure within the county; issued by County of Maui Public Works, Development Services Administration (DSA).
County of Maui - Building Permit (Public Works DSA) ↗The County of Maui Planning Department administers county zoning and development permitting; land use/zoning approvals may be required before a building permit is issued.
County of Maui - Planning and Permitting Section ↗Individual wastewater systems (septic) and cesspools are permitted by the Hawaii State DOH Wastewater Branch, not the county; applications are filed through the DOH e-Permitting system.
Hawaii DOH e-Permitting - Wastewater Branch Applications ↗Hawaii's owner-builder exemption (HRS 444-2.5 / 444-9.1) lets a property owner act as their own general contractor without a license for a building for their own use; the County of Maui provides a Contractor/Owner-Builder form (PS-FORM D) and disclosure statement.

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Hawaii’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
No well may be drilled without CWRM permits (HAR 13-168), including inside a designated Ground Water Management Area. But individual domestic use and rain-catchment are EXEMPT from the Water Use Permit even inside a designated area (HRS 174C-48) — a household faces construction permitting, not appropriation permitting.
Limit: CWRM Well Construction + Pump Installation Permit required statewide before drilling
Hawaii CWRM — Well Construction & Pump Installation; HRS 174C-48 ↗The Iao/Wailuku aquifer (central Maui) was designated in 2003 and is allocated near its sustainable yield — new non-domestic permits are hard to obtain — but a single-household well is exempt from the Water Use Permit (HRS 174C-48) and needs only the statewide construction permit.
Hawaii CWRM — Water Management Areas ↗The entire island of Molokai (Maui County) is a CWRM-designated Ground Water Management Area; new non-domestic withdrawals are permit-controlled, but individual domestic users and rain-catchment are exempt (HRS 174C-48).
