Summary

Clark County has no car-alarm-specific ordinance; a blaring alarm is enforced under the county's general unnecessary-noise ban, a misdemeanor.

City-specific rules exist: Henderson, and Las Vegas have their own car alarm limits rules that differ from Clark County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

It shall be unlawful to make, cause or suffer or permit to be made or caused upon any premises near any private residence, apartment house, dwelling house or public place in the unincorporated areas of Clark County, any unnecessary noises or sounds which are physically annoying to persons of ordinary sensitivity or which are so harsh or so prolonged or unnatural or unusual in their use, time or place, as to occasion physical discomfort.

Full Breakdown

Clark County Code has no section written for car alarms. A vehicle alarm that goes off and disturbs neighbors falls under Section 14.55.020, which bans any noise near a residence or dwelling that is physically annoying to persons of ordinary sensitivity or so harsh, prolonged, or unnatural as to cause physical discomfort. This applies only in unincorporated Clark County, including the Strip resort corridor in Paradise and Winchester townships. Las Vegas, Henderson, North Las Vegas, Boulder City, and Mesquite enforce their own municipal codes.

Violations & Fines

Violating Chapter 14.55 is a misdemeanor: up to 6 months in county jail, a fine up to $300, or both.
