Union City has no aircraft-noise ordinance and cannot adopt one. Aircraft operations near it, including Oakland and San Jose flight paths, are regulated by the FAA, which preempts local control of airspace and aircraft noise.
Nothing in the Union City Municipal Code, including Chapter 9.40, sets aircraft or overflight noise limits, and the community noise rules apply to ground-based machines, animals, and devices rather than aircraft in flight. Under federal law (the Federal Aviation Act and FAA authority), the regulation of aircraft operations, flight paths, and aircraft noise is preempted from local control, so cities cannot impose decibel limits on overflights. Union City lies under approach and departure corridors for Oakland International (OAK) and within the broader Bay Area airspace serving San Jose (SJC); noise concerns are handled through the operating airports' noise programs and the FAA, not city code. Residents typically direct overflight complaints to the relevant airport noise office.
No local citation applies to aircraft noise. Complaints are routed to the operating airport's noise-abatement office and ultimately the FAA, which holds jurisdiction over aircraft operations.
