Summary
Engine, motorcycle, and dirt bike noise are 'excessive noise sources' capped at 65 dB at the property boundary under Ordinance Code 5-01-1215(b). Off-road vehicle use near homes is restricted by Ordinance Code 4-23-1000. On public roads, California Vehicle Code Sections 27150-27151 (mufflers) control.
'Within one-half mile of' shall mean the distance measured from that part of a school, hospital, convalescent home, park or residential area closest to the point of operation of a motorcycle, motor bike or all-terrain vehicle. 'Residential area' shall mean any area one-quarter mile in depth abutting a public or private road, and one-quarter mile in length measured along such road, which contains any apartment house(s), condominium(s), multiple unit dwelling structure(s), or four or more residences of any kind or combination.
Full Breakdown
Vehicle noise in unincorporated Tulare County is addressed through both the County code and preempting state law. The Social Host Ordinance defines 'Excessive Noise Sources' in Section 5-01-1210(k) to include 'the frequent, repetitive, or continuous sounds from starting, operating, repairing, rebuilding, or testing of motor vehicles, motorcycles, dirt bikes, or other off-highway vehicles, or any internal combustion engines,' and Section 5-01-1215(b) caps such sound at 65 decibels at the property boundary. Separately, Chapter 4-23 of the Ordinance Code restricts where off-road vehicles may operate: Section 4-23-1000(a) makes it unlawful to ride or operate any motorcycle, motor bike, off-highway motor vehicle, or all-terrain vehicle on private property or unoccupied public property within one-half mile of any school, hospital, convalescent home, public park, or residential area.
For vehicles on public roadways, noise is controlled by California, not the County: Vehicle Code Section 27150 requires every motor vehicle to have an adequate muffler in constant operation to prevent 'excessive or unusual noise,' with no cutout or bypass, and Section 27151 prohibits modifying an exhaust system to amplify or increase noise beyond the limits in Vehicle Code Section 27200 et seq. The County General Plan Noise Element confirms that on-road traffic noise is preempted by state regulation.
Violations & Fines
Off-road operation violating Section 4-23-1000 and engine noise exceeding 65 dB under Section 5-01-1215 are enforced by the Sheriff's Office; the latter carries misdemeanor exposure and $1,000/$3,000 nuisance fines (Section 5-01-1235). Illegal mufflers and modified exhaust on public roads are enforced under the California Vehicle Code by law enforcement, typically as a correctable 'fix-it' citation requiring proof of repair.
