Full Breakdown
Oceanside's Noise Control Ordinance, City Code Section 38.12, makes it unlawful to produce noise whose one-hour average sound level exceeds the table limit at or beyond the source property's boundary. Limits run by base-district zone: Industrial 70 dBA (7 a.m.-9:59 p.m.) and 65 dBA (10 p.m.-6:59 a.m.); Commercial 65/60; single-family residential RS 50/45; high-density RH 55/50. Where two zones share a property line, the limit is the arithmetic mean of the two. A data center's continuous cooling towers, chillers, and backup generators are measured against the nearest receiver, so the 45 dBA overnight residential floor binds a site abutting homes.
Violations & Fines
Noise over the Section 38.12 limits on three or more days in thirty triggers a notice of noncompliance; a third violation within a year is a misdemeanor carrying fines up to $500 or jail.
