Full Breakdown
Newport Beach's Community Noise Control ordinance, Municipal Code Section 10.26.025, makes it unlawful to create noise that exceeds the receiving zone's standard when measured on another property. Limits by land use: single-, two-, or multiple-family residential (Zone I) 55 dB(A) daytime (7 a.m.-10 p.m.) and 50 dB(A) overnight (10 p.m.-7 a.m.); commercial (Zone II) 65/60; mixed-use residential (Zone III) 60/50; and industrial or manufacturing (Zone IV) 70 dB(A) at all hours. A data center's continuous chillers, cooling towers, and backup generators are measured at the nearest receiver; the 50 dB(A) overnight residential floor binds where IG land abuts homes.
Violations & Fines
Noise over the Section 10.26.025 limits, measured for any fifteen-minute period on another property, is a violation the city enforces through citations and, for permitted projects, breach of the noise conditions on the use permit.
