Noise from Specific Sources in San Bernardino, CA: What Residents Actually Need to Know
If you live in San Bernardino or are thinking about moving there, noise from specific sources are one of those things you probably won't think about until they affect you directly. San Bernardino has 3 specific rules on the books covering different aspects of noise from specific sources, and some of them might surprise you.
HVAC & Mechanical Noise
Electrically operated compressors, fans, and similar HVAC-type devices in San Bernardino can only run during the city's controlled noise hours: 8:00 a.m. to 8:00 p.m. in residential zones, 7:00 a.m. to 8:00 p.m. elsewhere. Running one outside those hours is a code violation.
Key details: Governing section: SBMC § 8.54.050(F). Residential allowed hours: 8:00 a.m.-8:00 p.m.. Non-residential allowed hours: 7:00 a.m.-8:00 p.m.. Covers: Compressors, fans, similar devices. No HVAC exemption: Not listed in § 8.54.060 exceptions.
Operating a compressor or fan outside the controlled hours is punishable under § 8.54.080 as an infraction or misdemeanor per § 1.12.010, escalating from a $100 fine on a first offense to $200 and $500 for repeats within a year, with a fourth violation charged as a misdemeanor carrying up to six months in jail and a $1,000 fine.
Car Alarm Limits
A motor vehicle burglar alarm sounding in San Bernardino must shut off within 15 minutes of going off. Letting it run longer, outside emergency use or testing, is a noise-code violation under the city's Noise Control chapter.
Key details: Termination deadline: 15 minutes from activation. Governing section: SBMC § 8.54.020(E). Exceptions: Emergency use, testing. Responsible person: Vehicle owner or lawful custodian. Repeat violation window: 72 hours triggers seizure.
A car alarm left sounding past 15 minutes is punishable as an infraction or misdemeanor under § 8.54.080 and § 1.12.010: up to $100 for a first offense, $200 for a second within a year, $500 for a third, and a misdemeanor with up to six months in jail and a $1,000 fine on a fourth. A repeat violation within 72 hours of a written notice also exposes the alarm equipment to confiscation under § 8.54.030(B).
Delivery Truck Noise
Loading or unloading trucks with excessive noise is flatly prohibited citywide under San Bernardino's Noise Control chapter, and the same chapter confines the activity to set daytime hours and keeps heavy trucks from idling more than 15 minutes an hour near homes.
Key details: Flat noise ban: SBMC § 8.54.020(I), any hour. Time-restricted loading: § 8.54.050(B), within 1,000 ft of homes. Heavy-truck idling cap: 15 minutes per hour, § 8.54.050(G). Weight threshold: Over 10,000 lbs GVW. Residential hours: 8 a.m.-8 p.m..
A loading-noise violation is punishable under § 8.54.080 as an infraction or misdemeanor per § 1.12.010, with fines of $100, $200, and $500 for successive infractions within a year and a misdemeanor exposure of up to six months in jail and a $1,000 fine on a fourth violation. Officers may also issue a written abatement notice under § 8.54.030 before citing.
