Maui County, HI Parking Rules: Driveway Rules (2026)

090 sets the paving standard for off-street parking areas countywide. Subsection A starts from a paving requirement: every required parking space, aisle, driveway, and lane must be paved with an asphalt or concrete surface, though the section already exempts single-family dwellings, accessory dwellings, duplexes, farm dwellings, farm labor dwellings, and commercial agriculture structures from that baseline paving mandate. Subsection B then lets the director allow or require unpaved surfaces after weighing the frequency of use, the character of the area, surrounding uses, durability, and maintenance needs.

Under that authority, up to ten spaces or 50 percent of a property's provided parking, whichever number is larger, can sit on grass, gravel, concrete mason grid pavers, or another surface the director finds appropriate. The exception widens sharply in two zoning contexts: in the State conservation district or the county's agricultural district, up to 100 percent of the provided parking spaces can be grass, gravel, or grid pavers, and the same 100 percent allowance applies in a Maui County historic district if paving would risk harming a historic property.

Subsection C adds that parking spaces beyond what the code requires, meaning surplus spaces a property chose to build, must still be either paved or finished in one of the same approved unpaved surfaces and kept in a condition that complies with the chapter.
