Do you need a permit for Window Replacement in Maui County?
In Hawaii, a Window Replacement requires a building permit.
In Maui County (Maui, Molokai and Lanai), building permits are county-run. A permit is generally required to replace windows because openings must meet Hawaii's high wind-pressure ratings (design winds up to 130 mph); in a flood zone or Special Management Area the review is stricter. Minor non-structural, same-size replacements may be exempt in Honolulu below the valuation threshold — confirm with the county. Plans are reviewed under the Maui County code (IRC 2018 IRC (HI)); apply through Maui County Planning Department before work begins.

With a growing population of around 164,522 residents, Maui County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
Code Compliance & Inspections
Because Hawaii sits in a hurricane-prone zone, the Hawaii State Building Code requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
Concurrent Permits & HOAs
For Maui County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your Window Replacement than the county itself.
Zoning & Cost Factors
Hawaii features a unique statewide zoning system where all land is classified into Urban, Rural, Agricultural, or Conservation districts by the State Land Use Commission. Fortunately, Hawaii maintains relatively builder-friendly regulations, keeping base permit fees competitive.
Estimated municipal base fee: $51–$78
