Full Breakdown
, unless the equipment stays within the specified noise levels measured at the property line of the location where it is used. That second clause matters for gas-powered leaf blowers in particular, since equipment that is quiet enough to meet the property-line noise standard is not confined to the daytime window the way louder equipment is. window mirrors the hours set for construction and repair noise under subsection G, so residents doing routine yard work and contractors doing construction work face the same daily clock, even though they are covered by separate subsections of the same section.
020(J)(4) carves out one specific exception: snowblowers not operated on a commercial basis are exempt from the noise chapter entirely when used to gain access to a city street, so clearing snow before or after the daytime window is not itself a violation.
Violations & Fines
Operating lawn or garden equipment, including gas leaf blowers, outside seven a.m. to nine p.m. while exceeding the property-line noise standard is enforced under the general penalty, Section 1.24.010: a first offense forfeits five to five hundred dollars plus costs, a repeat offense within a year forfeits twenty to one thousand dollars, with each day of continued use a separate offense.
