Full Breakdown
Chapter 18.02's general noise ordinance exempts most everyday noise sources from its decibel limits, but § 18.02.060(C) carves construction-related noise out of that exemption once it falls outside the permitted clock hours: 7 p.m. to 7 a.m. on weekdays and Saturday, and any time at all on Sunday or a federal holiday, unless the Director of Community Development has approved expanded work hours in advance. Outside those exempt hours, construction, repair, remodeling, grading, and authorized seismic survey noise is subject to the chapter's regular enforcement.
A separate, tighter curfew applies to routine property maintenance noise (mowing, blowing, etc.) under § 18.02.060(D): 7 a.m. to 6 p.m. on any day except Sunday, and 9 a.m. to 5 p.m. on Sunday. These clock-hour curfews sit alongside, and are enforced independently of, the decibel-based noise zone standards in § 18.02.050. The ordinance is administered by the city's Community Development Department, which can grant written approval for expanded construction hours on a project-specific basis when requested in advance.
Violations & Fines
Violating the noise ordinance, including running construction outside permitted hours without Director approval, is punishable under the penalty referenced at § 18.02.120 for that chapter's provisions, and each continuing occurrence can be treated as a separate violation subject to citation by code enforcement or police.
