RMC §7.35.010(B)(10) bars vehicle/motorcycle/motorboat/aircraft repair, rebuilding, modifying, or testing that disturbs across a residential line. Powered model vehicles are restricted between 7 p.m.–7 a.m. (§7.35.010(B)(7)). Operational on-highway vehicle noise is preempted by California Vehicle Code §27150 et seq.
Riverside's local noise code regulates vehicle-related noise on private property; in-use, on-highway vehicle noise is preempted by California Vehicle Code §§27150–27207 (mandatory mufflers; CHP-enforced 95 dB max under §27151 and SAE J1492 testing for motorcycles). Under RMC §7.35.010(B)(10), repairing, rebuilding, modifying, or testing any motor vehicle, motorboat, or aircraft is prohibited if the activity creates a noise disturbance across a residential property line or exceeds the underlying land-use category dBA standard — unless it is part of an officially sanctioned event. §7.35.010(B)(7) restricts powered model vehicles (RC cars, planes, boats — defined at §7.10.155) between 7:00 p.m. and 7:00 a.m. if they cause a disturbance across a residential or commercial property line, or any time they exceed the underlying decibel cap. §7.10.110 requires functional mufflers/sound dissipative devices. State preemption is acknowledged at §7.35.020(C).
Local violations enforced by Code Enforcement or RPD under §7.15.005 — misdemeanor or infraction, each day a separate offense. CVC §27151 violations (modified exhaust) are a CHP/RPD traffic infraction with a base fine plus state assessments (typically $200+ with fees) and a 'fix-it' correction requirement.
