Summary
State law (HRS 342F-30.8) makes it unlawful to run a leaf blower or similar powered equipment outside 8:00 a.m.-7:00 p.m. Monday-Saturday, or outside 9:00 a.m.-7:00 p.m. on Sundays and holidays, when within or within 100 feet of a residential zone.
Unlawful when the activity occurs outside the hours of 8:00 am - 7:00 pm, Monday through Saturday, or outside the hours of 9:00 am - 7:00 pm on Sunday and/or a State/Federal Holiday, AND within a residentially zoned area OR within 100 feet (30.48 meters) of a residentially zoned area.
Full Breakdown
Leaf blowers are regulated statewide under HRS 342F-30.8 (enforced by the DOH), which applies island-wide on Hawaii because the county is the only local government. Two conditions must both be met for use to be unlawful: (1) it occurs outside 8:00 a.m.-7:00 p.m. Monday through Saturday, or outside 9:00 a.m.-7:00 p.m. on Sunday and/or a State/Federal holiday; AND (2) it occurs within a residentially zoned area or within 100 feet (30.48 meters) of one. Use inside those hours, or well away from residential zones, is not restricted by this rule.
Violations & Fines
Violations are enforced by the DOH; each day of violation is a separate offense. Complaints go to the DOH noise program or police.
