Santa Paula Decibel Limits Rules (2026): What You Need to Know

Santa Paula Municipal Code Chapter 93, Section 93.20 establishes numerical noise limits keyed to zoning district. Residential zones — including single-family and multi-family designations — carry an exterior limit of 55 dBA between 7 AM and 10 PM and drop to 45 dBA during nighttime quiet hours from 10 PM to 7 AM. Commercial and mixed-use zones permit higher noise levels, generally 65 dBA during daytime hours and 60 dBA at night. Where a noise source in a louder zone affects a receiving parcel in a quieter zone, the limits of the quieter zone govern. Sound level measurements are made with an A-weighted slow-response meter at the property line of the receiving parcel, consistent with standard California noise ordinance methodology.

Noise that exhibits a tonal quality (a pure tone or narrow frequency band audible above background), an impulsive character (sharp banging or hammering sounds), or a repetitive on-off cycling pattern may be evaluated against a more restrictive effective threshold. Fixed mechanical equipment such as HVAC condensers, pool pumps, air compressors, and refrigeration units are among the most common sources of decibel-limit complaints in Santa Paula's residential neighborhoods. Residents near Highway 126 and the Santa Clara River industrial corridor should note that transportation and industrial uses carry separate exemptions and noise evaluation criteria under state law. The Santa Paula Police Department handles immediate noise disturbance calls, while the Code Enforcement Division manages ongoing or daytime complaints tied to fixed equipment or business operations.
