LAMC Section 114.06 requires vehicle theft alarm systems to automatically silence within 5 minutes. Violation is an infraction. Vehicle owners are responsible for ensuring their alarms comply, and chronically malfunctioning alarms may result in the vehicle being towed.
LAMC Section 114.06 specifically regulates vehicle theft alarm systems. Any vehicle theft alarm system that emits an audible sound must be equipped with a device that automatically and completely silences the alarm within five minutes of activation. This is one of the strictest car alarm regulations among major US cities. Violation of this section constitutes an infraction. The law applies to all vehicles within the City of Los Angeles, whether parked on public streets or private property. Vehicle owners are responsible for maintaining alarm systems in proper working order. Cars with malfunctioning alarms that sound repeatedly or fail to auto-silence may be subject to towing under the city's public nuisance provisions. LAPD and parking enforcement respond to car alarm complaints. Under the general noise provisions of LAMC 116.01, a persistently sounding car alarm also constitutes loud, unnecessary, and unusual noise. Residents can report chronic alarm problems through the MyLA 311 app or by calling 311.
Violation of Section 114.06 is an infraction with associated fines. Vehicles with alarms that fail to silence within 5 minutes may be cited each time the alarm sounds. Chronically malfunctioning alarms may justify towing as a public nuisance. Additional charges may apply under LAMC 116.01 for disturbing the peace.
