Los Angeles FAQ
Can I sue a helicopter operator for hovering over my house?
Direct nuisance claims often fail because federal law preempts altitude and routing rules. File complaints with heli-noise.org, the FAA Western-Pacific Region, and your council office to flag patterns for voluntary route changes.
Does LAPD respond to helicopter noise complaints?
Only when noise originates on the ground at a helipad. Airborne noise is FAA jurisdiction. LAPD's own air-support unit follows separate operational guidelines and is not subject to LAMC §41.40.
Topanga FAQ
Can LA County tell helicopters to fly higher?
No. Federal preemption under 14 CFR reserves altitude, route, and airspace rules to the FAA. The county can address only ground-based rotor noise at helipads through Title 12.08.
Where do I report a noisy helicopter?
File a complaint with the LA Helicopter Noise Coalition at heli-noise.com or call 1-800-WX-BRIEF. Logs are forwarded to the FAA's regional noise officer for trend tracking.
Are LASD or LACFD aircraft regulated locally?
Public-use government helicopters operate under federal rules with internal noise abatement procedures. Sheriff Air Support and Fire Air Ops voluntarily fly published routes but cannot be locally fined for overflights.
