Pomona's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Pomona, California, there are 9 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Industrial Noise

Pomona regulates industrial noise through Chapter 18, Article VII (Noise and Vibration Control) and the Zoning and Development Code Table 30-469 which sets noise standards by land use classification.

Industrial noise violations carry fines of $250–$2,500 per occurrence. Chronic violators face operating permit review and potential conditional use permit revocation. Abatement orders require compliance within 30 days.

Decibel Limits

Pomona City Code Chapter 18, Article VII (Noise and Vibration Control) establishes exterior noise standards measured in dBA. Residential zones have a daytime limit of 60 dBA (7 AM-10 PM) and nighttime limit of 50 dBA (10 PM-7 AM) at the property line.

Quiet Hours

Barking Dogs

Pomona City Code Chapter 6 (Animals) makes it unlawful to keep any dog or animal that by frequent or habitual barking, howling, or yelping disturbs the neighborhood. Animal noise also falls under the general noise ordinance in Chapter 18.

Key details: Code Section: Ch. 6 (Animals); Ch. 18, Art. VII. Standard: Frequent/habitual barking disturbing neighbors. Enforcement: Inland Valley Humane Society. Contact: IVHS: (909) 623-9777.

Pomona does not have a local aircraft noise ordinance. Aircraft noise is regulated at the federal level by the FAA. The nearest major airport is Ontario International Airport (ONT), approximately 8 miles east.
