Summary
The City of Ventura caps noise at the receiving property line by zone under Municipal Code Sec. 10.650.130: 70 dBA anytime on industrial land, but 50 dBA daytime and 45 dBA at night at homes. Data-center cooling and generators must meet the receiver's limit.
no person shall operate or cause to be operated any source of sound ... which causes the noise level when measured on any receiving property to exceed the following noise level limits: (a) The exterior noise levels for that land use ... for a total period of more than 30 minutes in any consecutive 60 minutes

Full Breakdown
Ventura's Noise Control ordinance, Municipal Code Sec. 10.650.130, assigns each receiving property to a noise zone: Zone I noise-sensitive, Zone II residential, Zone III commercial, Zone IV industrial and agricultural. Exterior limits are Zone IV 70 dBA anytime; Zone III 60 dBA day (7 a.m.-10 p.m.) and 55 dBA night (10 p.m.-7 a.m.); Zone II 50 dBA day and 45 dBA night; Zone I 50/45. At a boundary between two zones the lower limit applies. A fixed noise source includes generators, compressors, air-conditioners and refrigeration equipment - exactly a data center's cooling and backup power. Where an industrial site abuts homes, the 45 dBA overnight residential limit binds. Short-duration exceedances above the base level are allowed on a sliding scale.
Violations & Fines
Noise over the Sec. 10.650.130 limits is a code violation enforced by the City through citations, and for a use-permitted data center it breaches the noise conditions imposed on the permit.
