Eastvale, CA Noise Ordinances: Vehicle Noise (2026)

Eastvale's noise ordinance addresses vehicle noise directly under EMC 8.52.060(1). For motor-vehicle sound systems (subsection (1)(b)), no person may operate a vehicle stereo, whether affixed to the vehicle or not, between 10:00 p.m. and 8:00 a.m. such that it is audible to the human ear inside any inhabited dwelling; at any other time it may not be audible more than 100 feet from the vehicle. For off-highway vehicles (subsection (1)(a)), the vehicle must be equipped with a USDA-qualified spark arrester and a constantly operating, properly maintained muffler (no cutout or bypass), and the noise emitted may not exceed 96 dBA for vehicles manufactured on or after January 1, 1986, or 101 dBA for vehicles built before that date, measured 20 inches from the tailpipe using SAE Standard J-1287. Importantly, ordinary on-road motor vehicles other than off-highway vehicles are exempt from the chapter under EMC 8.52.020(11), and that exemption does NOT include the vehicle's sound system, so engine and exhaust noise from a normal car on the street is generally governed by the California Vehicle Code rather than EMC 8.52, while the car's stereo remains subject to the 8.52.060(1)(b) limits. Heating and air-conditioning equipment and safety/warning/alarm devices (including car alarms) are also exempt under EMC 8.52.020(12)-(13).
