Leaf Blower. A "leaf blower" is a small, combustion engine-powered or electric device used for property or landscape maintenance that can be hand-held or carried by the operator and which operates by propelling air under pressure through a cylindrical tube. It is unlawful for any person to operate a leaf blower on private property in or adjacent to a residential use except between the hours of eight a.m. and eight p.m. Effective January 1, 2000, all leaf blowers operated in or adjacent to a residential area shall operate at or below a noise level of 65 dBA at a distance of 50 feet, as determined by a test conducted by the American National Standards Institute or an equivalent. The dBA rating shall be prominently displayed on the leaf blower.
Full Breakdown
030(c)(4) of the Operating Standards chapter defines a leaf blower as any small combustion-engine or electric device, hand-held or carried, that clears yard debris by propelling pressurized air through a cylindrical tube, and it regulates the tool separately from the chapter's general operational dBA limits. is unlawful regardless of how quiet the machine runs. Layered on top of the hours limit is a hard noise ceiling that took effect January 1, 2000: every leaf blower operated in or adjacent to a residential area must run at or below 65 dBA measured at a distance of fifty feet, verified by a test conducted to American National Standards Institute protocols or an equivalent standard.
The section also requires the dBA rating to be prominently displayed on the leaf blower itself, so code enforcement or a neighbor can check a unit's certified rating without field-testing it. Because the rule reaches devices used 'in or adjacent to' a residential use, it covers landscaping crews working commercial or multifamily sites next to houses, not just homeowners on their own lots. leaf blower still must meet the 65 dBA/50-foot ceiling.
Violations & Fines
Operating a leaf blower outside the eight a.m. to eight p.m. window, or above 65 dBA at fifty feet, adjacent to a residential use violates § 19.42.030(c)(4). Zoning code violations default to a misdemeanor under § 1.04.010 and § 1.04.020: up to a $1,000 fine, up to six months in county jail, or both, with each day of continued use a separate offense. The city fields complaints through its Neighborhood Complaint program and can require the operator to produce the machine's displayed dBA rating.
