Full Breakdown
West Covina regulates noise through Municipal Code Chapter 15, Article IV - a nuisance standard, not a decibel table like Los Angeles County. Sec. 15-85 makes it unlawful in any residential zone to make loud, unnecessary, or unusual noise that disturbs the peace; noise plainly audible 50 feet beyond the property line is presumed a violation. Sec. 15-95 (construction) and Sec. 15-96 (vehicle testing) cap noise at 5 decibels over the ambient level. A data center's continuous cooling towers, chillers, and backup generators near homes must meet the Sec. 15-85 nuisance standard; discretionary permits can add project-specific noise conditions.
Violations & Fines
Noise violating Chapter 15 is a misdemeanor enforced by the City; a permitted data center also breaches the noise conditions attached to its Administrative Permit or Conditional Use Permit.
