Buena Park, CA Noise Ordinances: Vehicle Noise (2026)

Buena Park requires off-road vehicles, motorcycles, motor-driven cycles, minibikes, trail bikes, motorscooters, jeeps and dune buggies, driven on privately owned, undeveloped land within the city to carry noise inhibitors adequate for lawful operation on a public highway; running one without a functioning muffler meeting that standard is a violation even on private property. The rule exempts landscaping, excavating and weed-eradicating equipment, and any site at least 1,500 feet from the nearest dwelling, church, school or place of assembly. It does not separately regulate car stereos or modified exhausts on public streets, ordinary street driving falls under the state Vehicle Code's muffler requirements instead.
