Summary
A car horn, siren or alarm left sounding longer than necessary is a cited violation in unincorporated Collier County under Sec. 54-93(D)(3), the same no-meter-needed section that covers vehicle noise. An officer and the complainant only need to agree the sound is unreasonably loud, raucous or a nuisance at a residential site; the Sheriff's Office enforces it on public roads.
(1)Unreasonably loud, raucous or jarring: (is clearly annoying or clearly disturbing to any individual of normal sensibilities at such site); or(2)A nuisance: (without reasonable justification is unreasonably interfering with the peace and quiet of any individual of normal sensibilities at such site). ... (3)Sound Producing Device. These devices include every device designed to produce, reproduce or amplify sound, whether or not related to a vehicle, such as horn, siren, whistle, bell, musical instrument, radio, TV, phonograph, speaker, loudspeaker, microphone, or other substantially similar device, including when a horn, siren, whistle, bell or similar device is sounded longer than necessary. These noises are enforceable by the Sheriff's Office, but shall not be enforceable by Code Enforcement officers unless the sound producing device is off road.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 126 | Land Development Code: Supplement 33).
Full Breakdown
Sec. 54-93 lets Collier County cite four specific noise sources, including 'sound producing devices,' without a Sound Level Meter reading, so long as the affected site is classified residential and an enforcement officer together with the complainant observes the sound as unreasonably loud, raucous or jarring, or as a nuisance interfering with an ordinary person's peace and quiet. Subsection D(3) defines a sound producing device broadly: any device designed to produce, reproduce or amplify sound, vehicle-related or not, expressly naming a horn, siren, whistle or bell, and it specifically flags a horn, siren, whistle or bell 'sounded longer than necessary' as a violation, which covers a car alarm that keeps blaring after it should have reset or been silenced.
As with the rest of the vehicle-noise provisions, enforcement is split by location: the Sheriff's Office handles these complaints, and Code Enforcement officers may act only when the device is off the road. Collier's separate Chapter 5 False Alarm Ordinance, by contrast, governs monitored security alarm systems on buildings, not vehicle alarms, so a blaring car alarm falls under the noise ordinance rather than the alarm-registration rules. Subsection D(4) exempts noise typical of a lawful business's normal hours and type of operation.
Violations & Fines
A car-alarm citation follows the noise ordinance's standard fine ladder in Sec. 54-90: $100 for a first violation, $250 for a second, and $500 for a third or later violation, each imposed by the Code Enforcement Board, Special Magistrate or a court. Repeated adjudicated violations tied to the same sound-producing device within 12 months can lead to confiscation of the device or equipment until the owner demonstrates compliance.
