Noise Ordinances in Lewisville, TX

If you live in Lewisville or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Lewisville has 7 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.

Vehicle Noise

Lewisville bans bells, sirens, compression horns and exhaust whistles on private vehicles, reserving them for law enforcement, fire and ambulance duty, and separately bars mounting a loudspeaker or sound-amplifying equipment on any vehicle so it is audible 50 feet away on a street, alley, sidewalk or park. Sec. 9-5(b)(1) covers both.

A violation is punished under the Code's general penalty, Sec. 1-15, a fine up to $500.00 per offense, with each day a separate violation. Lewisville police can cite the vehicle owner or operator on the spot for an unauthorized horn, siren or exhaust whistle, or for sound-amplifying equipment audible 50 feet from the vehicle on a public street.

If you are coming from a city with tighter rules, you will find Lewisville gives residents more flexibility on decibel limits.

Barking Dogs

Lewisville treats frequent or prolonged barking, howling, crowing, or other animal noise that disturbs neighbors as a nuisance under Chapter 3 of the city code. An owner isn't cited for a single bad night: the violation only attaches once an animal control officer or police officer has given notice of a noise complaint and the owner fails or refuses to stop the disturbance and keep it from happening again.

Key details: Governing section: City Code § 3-2(1). Trigger for a citation: Notice given, then disturbance continues. Who can cite: Animal control officer or police officer. Maximum fine: $500 per day (§ 1-15). Noise covered: Barking, howling, crowing, bawling, squealing.

A first substantiated noise complaint typically brings a warning notice from animal control or police rather than an immediate ticket; the citable offense is failing to stop the disturbance after that notice. Citations carry fines up to $500 per day under the Section 1-15 general penalty, with every additional day of barking treated as a separate offense, and skipping a required municipal court appearance adds its own Section 3-45(c) violation.

Amplified Music & Outdoor Sound

Lewisville prohibits amplified music plainly audible at a neighboring property during quiet hours of 10 p.m. to 7 a.m. under Ch. 18. City events require sound permits.

Key details: Quiet Hours: 10 p.m. to 7 a.m.. Standard: Plainly audible at property line. Events: City sound permits required. Max Fine: 500 dollars per violation.

Class C misdemeanor; fine up to 500 dollars per violation.

Lewisville is more permissive than most cities when it comes to amplified music & outdoor sound. That said, there are still limits.

Leaf Blower Rules

Lewisville bars running leaf blowers, lawnmowers and other motorized power equipment outdoors in residential zones, or within 150 feet of a home, during nighttime hours. Sec. 9-5(b)(2) sets fixed nighttime windows that start as early as 10:00 p.m. on weeknights, so early-morning or late-evening yard work can trigger a citation.

Key details: Governing section: Sec. 9-5(b)(2), Chapter 9 Nuisances. Covers: Leaf blowers, mowers, tractors, similar equipment. Buffer: 150 feet of a residence boundary line. Weeknight cutoff: 10:00 p.m. to 7:00 a.m., Mon-Thu. Max fine: $500 per offense under Sec. 1-15.

A power-equipment noise violation carries the Code's general penalty under Sec. 1-15, a fine up to $500.00 per offense, with each day of continued violation a separate offense. Enforcement is complaint-driven through the police department, and a landscaper or homeowner running a leaf blower after the Sec. 9-1 nighttime cutoff can be cited even without a decibel reading.

The Bottom Line
