Full Breakdown
Lynwood Municipal Code § 3-12.5 sets the City's ambient base noise standards, measured in A-weighted decibels under § 3-12.3, that noise reaching a neighboring property may not exceed for the zone in which that property sits. Residential R-1 and R-2 zones are capped at 60 decibels during the day (7:00 a.m. to 7:00 p.m.), evening (7:00 p.m. to 10:00 p.m.) and night (10:00 p.m. to 7:00 a.m.) alike; the higher-density R-3 zone matches those day and evening caps but drops to 55 decibels at night.
Commercial zones may run at 65 decibels during the day and evening, falling to 60 decibels at night, while manufacturing zones are allowed 75 decibels around the clock. Section 3-12.5b resolves boundary disputes: where a receiving property sits on the line between two zones, the lower, quieter zone's limit governs. Measurements follow the procedures in § 3-12.4: readings are taken at the receiving property's line, at least ten feet from any building, wall or obstruction, with no one but the operator within ten feet of the meter, recorded at fifteen-second intervals over at least fifteen minutes.
A source that exceeds the applicable limit is a violation of § 3-12.5 regardless of whether anyone complains, and the section works alongside the separate disturbing-the-peace standard at § 3-12.6, which reaches noise below these numeric limits if it is still unreasonable for the area.
Violations & Fines
Exceeding the zone's ambient base level under § 3-12.5 is a misdemeanor under the chapter's penalty clause, Lynwood Municipal Code § 3-12.19, punishable as provided in § 1-5, or it may instead be filed as an infraction by the city prosecutor; each day of continuing excess noise is a separate offense.
