San Jose FAQ
Can I stop overnight grocery deliveries on my San Jose street?
Possibly. If back-up alarms or pallet noise exceed SJMC 20.100 nighttime limits of about 50 dBA at your property line, file a complaint with Code Enforcement. The store may be required to install sound walls or change loading times.
How loud can a diesel truck legally be in San Jose?
California Vehicle Code §23130 sets statutory drive-by sound limits enforced by SJPD; §27007 bans modified or defective exhaust. A truck registering above 80 dBA on a calibrated meter generally triggers a citation requiring proof of repair.
Are food delivery vans subject to the same idling rules?
Yes for diesel vehicles, which are capped at five minutes idling under CARB rule 13 CCR §2485 statewide. Gasoline-powered vans are not subject to that specific rule but remain subject to SJMC noise ordinances if they disturb neighbors.
Santa Clara FAQ
Can a city ban delivery trucks at night?
Cities cannot override state noise caps but can restrict commercial loading-zone activity hours in residential-adjacent areas. San Jose and Sunnyvale impose nighttime loading limits near residential frontages enforced through zoning conditions.
How do I report a noisy delivery truck?
Note time, location, company name, and DOT number, then call CHP 1-800-TELL-CHP for moving violations or SCC code enforcement for loading-zone activity. Idling complaints go to CARB or the local air district.
