Construction hours in Fontana, CA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Fontana permits construction activity during standard Inland Empire daytime windows. Typical allowed hours are 7 AM to 8 PM Monday through Friday and 8 AM to 6 PM Saturday, with Sunday and holiday work near residences generally prohibited under Chapter 18 nuisance rules.
Fontana folds construction noise into its Chapter 18 nuisance provisions rather than calling it out in a dedicated construction-noise article. In practice, building inspectors and Code Enforcement apply the commonly observed San Bernardino County construction window: Monday through Friday 7 AM to 8 PM, Saturdays 8 AM to 6 PM, and no work on Sundays or City-observed holidays when the job site is within audible range of residences. Warehouse and commercial tenant improvements in industrial areas like the Jurupa Avenue and Slover Avenue logistics corridors often run longer hours but must still avoid sound that spills into adjoining residential neighborhoods after 10 PM. Haul routes, truck deliveries, and generator use follow the same daytime discipline. Fontana does allow construction outside these hours only where an advance noise permit or special waiver is issued, typically for emergency repair or utility work. File complaints with Code Enforcement at (909) 350-7626.
