Los Angeles FAQ
Can I report an idling delivery truck outside my home at midnight?
Yes. Call LAPD non-emergency for the immediate noise and parking violation, and report repeat offenders to Bureau of Street Services. LAMC §80.36.4 plus §41.40 both apply during overnight hours.
Are loading-dock deliveries near my apartment regulated?
Yes. Conditional-use permits typically restrict deliveries to daytime windows. Check the project's CUP through Department of City Planning records, then file complaints with LADBS or your council office for violations.
South San Gabriel FAQ
Can grocery stores get pre-dawn deliveries?
Yes if their conditional use permit allows it. Without a CUP, LA County Code §12.08.500 bars 10pm-7am deliveries adjacent to residential zoning. Many older sites are grandfathered with operating-hour conditions.
Who enforces idling complaints?
California Air Resources Board hotline 1-800-END-SMOG accepts truck-idling reports. Local code enforcement and LASD may also cite under the noise ordinance if idling generates a sustained disturbance.
Are reefer units exempt?
No. Refrigeration units count toward both noise limits and CARB's anti-idling rule, with limited 30-minute startup grace. Operators must use shore-power hookups at compliant terminals where available.
