Full Breakdown
Section 9.08.050(I) is one of the enumerated loud-or-raucous-noise categories in Chapter 9.08, Offenses Against Public Peace. It bars noise sources associated with construction, demolition, grading, repair or remodeling of any real property outside two windows: 7:00 a.m. to 8:00 p.m. Monday through Friday, and 9:00 a.m. to 6:00 p.m. on Saturdays, Sundays and legal holidays. The only exception the section allows is an emergency where the work is immediately required to prevent injury to persons or damage to property, and that emergency determination rests with the director of building and safety or that director's designated representative, not with the contractor or property owner.
Because the construction-hours rule sits inside the general noise chapter rather than a stand-alone building-permit section, it is enforced the same way as the rest of Section 9.08.050: as a misdemeanor or infraction under Section 9.08.060(A), at the discretion of the prosecuting authority, with each day of an out-of-hours violation potentially a separate offense. Section 9.08.060(B) adds that repeated noise-disturbance calls to the same job site within a 24-hour period can generate a service-fee charge for police personnel and equipment, billed under a fee schedule the city council sets by resolution, and Section 9.08.060(C) allows the city to treat chronic construction-noise complaints as a public nuisance subject to abatement under Chapter 8.16, including injunctive relief from a court.
Violations & Fines
Construction, demolition, grading, repair or remodeling noise outside 7 a.m.-8 p.m. weekdays or 9 a.m.-6 p.m. weekends and holidays violates Section 9.08.050(I) and is a misdemeanor or infraction under Section 9.08.060(A). Repeated calls to the same site within 24 hours can add a police service fee, and the city may pursue nuisance abatement under Chapter 8.16 for chronic violations.
