Los Angeles County
South Gate has no local aircraft noise ordinance. Aircraft in flight are preempted by federal law (FAA/Noise Control Act of 1972); ground-level airport noise standards are set by Caltrans Division of Aeronautics under Cal. Pub. Util. Code §21669 using a 65 dB CNEL threshold for incompatible residential exposure. South Gate is in the Los Angeles County urban core; while not adjacent to LAX, the city sits under jet approach corridors and helicopter routes used by LAPD/LASD, news media, and medical operators. Noise complaints about aircraft must be directed to the operating airport's noise office (LAX, Long Beach, Compton/Woodley) or the FAA Western-Pacific Region, not to South Gate Code Enforcement.

Inglewood FAQ
Does Inglewood regulate aircraft noise?
Section 5-33 prohibits jet engine testing above 50 dBA between 10 PM and 7 AM. Aircraft during normal airport operations are exempt. LAX flights are regulated by the FAA.
Can I get free soundproofing in Inglewood?
Yes. The Residential Sound Insulation Program provides free acoustically rated windows, doors, and ventilation to eligible homes in LAX noise contours.
South Gate FAQ
Can South Gate Code Enforcement stop a noisy plane or helicopter?
No. Aircraft-in-flight noise is federally preempted under the Noise Control Act of 1972 and FAA regulations. South Gate Municipal Code does not cover aircraft. Complaints must go to the FAA or the operating airport's noise office.
Why are police helicopters allowed to hover so low at night?
FAR 91.119(d) exempts law enforcement, EMS, and operations necessary for the helicopter's intended purpose from the 1,000-foot minimum-altitude rule over congested areas. LAPD, LASD, and news helicopters are routinely lawful at low altitude.
Is South Gate inside an airport CNEL 65 contour?
No major commercial airport's 65 dB CNEL contour extends into South Gate per Caltrans noise inventories. The closest impact comes from Long Beach Airport approach paths and Compton/Woodley general aviation, neither of which produces 65+ CNEL exposure in South Gate residential areas.
