Full Breakdown
10, Article II regulates off-street construction noise separately from the general noise chapter. m. on non-holiday Saturdays. No work of any kind is permitted on Sundays, since Sunday hours are never listed, or on the eight enumerated holidays: January 1st, the third Monday in January (MLK Day), the third Monday in February, the last Monday in May, July 4th, the first Monday in September, Thanksgiving Day and the day after, and December 25th. 240 carves out five exemptions from the hours restriction: emergency construction and repair necessary to protect life and property; operations preempted from local regulation by state law, such as public school construction; furnishing of utility-type services including utility facility construction and maintenance; public inspections; and any work on an existing single-family or duplex dwelling undertaken by the property owner personally.
210 explains the rationale: the City Council found that unregulated construction timing near residential properties causes excessive and annoying noise, dust and fumes that adversely affect public peace, health, welfare and safety. 070(e), confirms construction activity is exempt from the chapter's fixed-source noise-level standards only 'during allowed hours, as otherwise specified in the Code,' tying the two provisions together.
Violations & Fines
Enforcement runs through Section 1.05.070, giving the City prosecutorial discretion to pursue a construction-hours violation as a criminal, civil, or administrative action. The City Manager or a designee may first seek voluntary compliance through warning, notice, or educational outreach before pursuing formal enforcement, per Section 9.10.110's general enforcement-manner provision incorporated for this article.
