Fontana FAQ
Can a warehouse run trucks all night next to homes?
Only within its CUP noise conditions and the Zoning Code nighttime limits. Idling is capped at five minutes by state rule.
What if beep-beep backup alarms wake me up?
Backup alarms are required by OSHA, but the operator can use broadband white-noise alarms to reduce impact. Raise the issue with Code Enforcement and reference the CUP.
Hesperia FAQ
Is there a fixed dBA limit for a Hesperia warehouse at night?
Hesperia uses a nuisance test under Code Chapter 8.32 combined with General Plan Noise Element CNEL compatibility. New development near sensitive uses must demonstrate exterior residential exposure at or below the Normally Acceptable range (around 60 dBA CNEL) per the OPR matrix.
How do I report a factory or distribution yard for nighttime noise?
File a complaint with Hesperia Code Enforcement at (760) 947-1000. Sustained noise audible across the property line, particularly after 10 p.m., is treated as a public nuisance under Chapter 8.32 and is abatable.
