Summary
Oxnard's Sound Regulation ordinance caps exterior noise at the property line by sound zone: 55 dBA day and 50 dBA night at homes, 70 dBA day and night on industrial (M-L, M-1, M-2) land. Section 7-185 governs; a data center's cooling and generators must comply.
No person at any location within the city shall create, maintain, cause or allow any sound on property which causes the sound level, when measured on any other property, to exceed: The allowable exterior sound level for a cumulative period of more than 30 minutes in any hour.

Full Breakdown
Oxnard's Sound Regulation ordinance (Chapter 7, Article XI) assigns every property to a sound zone and sets exterior limits measured at the source property line. Sound Zone I (residential) allows 55 dBA from 7 a.m. to 10 p.m. and 50 dBA overnight; Sound Zone II (commercial) allows 65/60 dBA; Sound Zone III (industrial - M-L, M-1, M-2) allows 70 dBA day and night. At a boundary between two zones, the lower limit applies, so a data center on industrial land abutting homes is held to the 55/50 dBA residential cap. Because cooling towers and chillers run continuously, the measured level is compared directly to the limit under Section 7-185(F).
Violations & Fines
Noise exceeding the Section 7-185 limits is a public nuisance and a misdemeanor punishable by a fine up to $1,000 or six months in jail, with each day a separate offense.
