Ventura County
Ventura regulates industrial and commercial noise through Chapter 10.650 of the San Buenaventura Municipal Code (Noise Control), which establishes designated noise zones with exterior sound-level limits measured at receiving-property lines. Industrial-zoned parcels receive higher allowable dBA than residential, and noise crossing into a residential zone is judged by the lower (residential) limit. The chapter is enforced by Ventura PD and Code Enforcement.

Santa Paula FAQ
What noise limit applies to a new industrial or agricultural operation in unincorporated Ventura County?
Under General Plan Policy HAZ-9.2, a new noise generator near a sensitive use must keep outdoor noise at the receptor's exterior wall within 55 dBA Leq during the day, 50 dBA in the evening and 45 dBA at night, or the ambient level plus 3 dBA, whichever is greater.
Does the County require a noise study for industrial projects?
Yes, where a project involves noise generation above the established standards. Policy HAZ-9.4 requires an acoustical analysis by a qualified acoustical engineer documenting existing and projected noise levels and recommending mitigation.
Ventura FAQ
A factory next to my house runs compressors all night — what's the rule?
Under SBMC Ch. 10.650, the receiving zone (your residential parcel) sets the applicable nighttime dBA limit at your property line, even if the source is in an industrial zone. File a complaint with Ventura Code Enforcement.
Do OSHA noise rules apply to my neighbor's business?
Cal/OSHA 8 CCR §5096 protects workers inside a facility — it does not set limits on noise emitted to neighboring properties. Use SBMC Ch. 10.650 for off-site impacts.
Can I sue for industrial noise?
Yes — Cal. Civil Code §3479 defines nuisance to include anything injurious to comfortable enjoyment of property; civil actions are independent of the City's administrative process.
