Full Breakdown
The noise ordinance's exemption list covers only three sources, and temporary construction, repair, or demolition work is one of them, but only for work performed between 7:00 a.m. and 7:00 p.m., excluding Sundays and federal holidays. Work outside that window, or occurring on a Sunday or holiday, loses the exemption and must instead meet the same decibel limits and cumulative-time thresholds set for the property's zone under Section 16.20.125(B). The building official enforces the standard as noise control officer, and violations may be abated as a public nuisance under Section 16.20.120.
Violations & Fines
Running construction equipment before 7 a.m., after 7 p.m., or on a Sunday or federal holiday strips the noise exemption, exposing the activity to the zone's standard decibel limits and nuisance abatement.
