Fire Sprinkler Requirements
Maui County has no general residential sprinkler mandate, but its Hawaiian Provisions for Indigenous Hawaiian Architecture require automatic fire sprinklers on a hale (traditional Hawaiian structure) that sits too close to neighboring buildings or property lines. A hale set back at least 100 feet needs no sprinklers at all.
