Industrial properties in Corona's North Main Industrial Corridor and along the 91 and 15 freeways are subject to noise standards in Corona MC Chapter 9.36, with separate daytime and nighttime decibel limits at the receiving property line. Industrial uses adjacent to residential zones must mitigate to residential standards at the boundary.
Corona's industrial base includes warehousing and light manufacturing in the North Main Corridor, the Sierra Avenue industrial area, and along Pomona Road and Sampson Avenue serving the 91/15 freeway logistics corridor. Corona Municipal Code Chapter 9.36 sets exterior noise limits of 75 dBA daytime (7 a.m. to 10 p.m.) and 70 dBA nighttime at industrial-zoned receiving properties, but where industrial uses abut residential zones, the receiving residential standard of 55 dBA daytime / 45 dBA nighttime applies at the residential property line. Truck idling at warehouse and distribution facilities is further regulated by California Air Resources Board's anti-idling regulation (13 CCR 2485) limiting heavy-duty diesel idling to 5 minutes. Stationary equipment such as rooftop HVAC, refrigeration condensers, generators, and air compressors must be acoustically screened during plan check when located within 200 feet of residential zoning. Persistent industrial noise complaints are investigated by Code Enforcement, often using calibrated Type 2 sound level meters with measurements averaged over a 1-hour Leq period.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Corona code enforcement directly for current fines, enforcement procedures, and hearing options.
