San Jose FAQ
Can San Jose make helicopters fly higher over my house?
No. Federal law preempts city control of navigable airspace. Only the FAA can set helicopter altitudes and routes. The city cannot enforce SJMC noise limits against airborne aircraft regardless of decibel readings on the ground.
Where do I report a low-flying helicopter in San Jose?
Call the FAA Flight Standards District Office in San Jose at (408) 291-7681 or file online at faa.gov. For Mineta SJC airport-related operations, also log complaints through the SJC noise abatement office at (408) 392-1265.
Are news and police helicopters subject to any local rules?
Police and medical units operate as public aircraft with broader FAA latitude. News helicopters follow standard Part 91 rules. None are subject to San Jose noise ordinances; complaints serve only as feedback to operators and the FAA.
