Bakersfield, CA Noise from Specific Sources: Delivery Truck Noise (2026)

Delivery and refrigerator trucks are addressed by name in Bakersfield's general noise chapter. Municipal Code § 9.22.030(C) permits refrigerator trucks to operate in any commercial or manufacturing zone at all hours, recognizing that cold-chain deliveries and idling reefer units are a routine part of commercial operations. The permission is conditional, though: it does not extend to use that emits noise or vibration detrimentally impacting neighboring residential properties and their occupants between ten p.m. and seven a.m. Outside that nighttime window, or in a zone that isn't commercial or manufacturing, a refrigerator truck's noise instead falls under the general nuisance standard in § 9.22.030(A)-(B), which asks whether the noise disturbs the peace of a neighborhood or annoys residents within 1,000 feet, weighed against factors like proximity to sleeping areas, duration and whether the noise is recurrent.

Because the definition of 'construction' in § 9.22.020 separately captures the 'transportation or delivery of any materials, tools, equipment or personnel to or from the site of any construction project,' delivery-truck noise tied to an active construction site is instead governed by the construction-hours rule in § 9.22.050, not this refrigeration carve-out. Enforcement follows Chapter 1.40's general penalty provisions, and repeat responses to the same address within 30 days trigger the § 9.22.060 service fee billed under Chapter 3.70.
