Summary
Data-center cooling and refrigeration equipment in Los Angeles may not raise noise more than 5 dBA above the ambient level at another property, under LAMC Section 112.02. Where ambient is low, presumed floors apply: 50 dBA day and 40 dBA night at homes.
It shall be unlawful for any person, within any zone of the city to operate any air conditioning, refrigeration or heating equipment... in such manner as to create any noise which would cause the noise level on the premises of any other occupied property... to exceed the ambient noise level by more than five (5) decibels.
Full Breakdown
The City regulates data-center noise through its general Noise Regulation (LAMC Chapter XI). Section 112.02 makes it unlawful to operate air conditioning, refrigeration, or heating equipment so that it raises the noise level on another occupied property more than 5 decibels above ambient: squarely covering data-center chillers and cooling systems. Backup generators and other machinery fall under Section 112.01's matching 5-dBA-over-ambient rule. When actual ambient is quieter than the presumed levels in Section 111.03 Table II, those floors govern: 50 dBA daytime and 40 dBA nighttime in residential zones, 60/55 in commercial and M1/MR zones, and 65 dBA in the M2 and M3 heavy-industrial zones.
Violations & Fines
Cooling equipment or generators that push noise more than 5 dBA above ambient at a neighboring property violate LAMC Sections 112.01 and 112.02, subject to citation and abatement by the City; pure-tone and repeated noise draw added enforcement.
