Noise from Specific Sources in Grand Prairie, TX

Grand Prairie maintains 137 local ordinances across all categories, and 3 of those deal specifically with noise from specific sources. Here is a breakdown of what the city actually requires, what is prohibited, and where Grand Prairie falls on the strict-to-permissive spectrum compared to other cities.

Delivery Truck Noise

Grand Prairie confines truck loading, unloading and idling noise near homes to daytime hours. Sec. 13-277(11)(d) limits loading and unloading of trucks and similar large vehicles within a residential district or 300 feet of one to daytime, and (e) caps idling of any vehicle over 10,000 pounds GVW there to fifteen minutes.

Loading or unloading a one-ton-plus truck, or idling any vehicle over 10,000 pounds GVW for more than fifteen minutes, inside a residential district or within 300 feet of a residential structure outside daytime hours (6 a.m. to 10 p.m.) violates Sec. 13-277(11)(d)-(e) absent a director-approved urgent-necessity exception, and is a misdemeanor under Sec. 13-285, fined under Sec. 1-8 with each day a separate offense.

Car Alarm Limits

Grand Prairie treats the continued or frequent sounding of a vehicle horn, alarm or other signal device, outside a genuine warning use, as a presumed noise nuisance under Sec. 13-277(4). It becomes a chargeable offense once it is plainly audible thirty feet away in a public space or disturbs a person at the receiving property line.

Key details: Governing section: Sec. 13-277(4), presumptions. Trigger: Continued or frequent horn/signal use. Enforcement distance: 30 ft in public right-of-way. Residential daytime cap: 85 dB(A) max / 65 dB(A) Leq. Residential nighttime cap: 78 dB(A) max / 58 dB(A) Leq.

Letting a horn, siren or car alarm sound continuously or frequently for no warning purpose is a presumed nuisance under Sec. 13-277(4); it becomes a citable offense under Sec. 13-278(a) once a peace officer can plainly hear it thirty feet away or it exceeds the Noise Zone 1 residential cap of 85 dB(A) daytime or 78 dB(A) at night. Violations are misdemeanors fined under Sec. 1-8, with each day counted as a separate offense.

Low-Frequency Bass Limits

Grand Prairie caps low-frequency noise from gas well drilling at 65 dB in each of the 16, 32 and 64 hertz octave bands, measured outdoors at the nearest protected use. Pure tones at 125 hertz and below cannot exceed neighboring bands by more than 15 dB. The limits sit in Code of Ordinances § 13-515(d) and bind every operator holding a city gas well permit.

Key details: Low-frequency cap: 65 dB in the 16, 32 and 64 hertz octave bands. Pure-tone margin: 15 dB at 125 hertz and below; 8 dB at 160 to 400. Measuring point: Property line or 100 feet from the nearest protected structure. Ambient study: 72 hours, including one 24-hour weekend reading. Close-in monitoring: Continuous, with weekly reports, within 1,000 feet of a protected use.

Under § 13-512, the gas inspector sends written notice naming the failure and a reasonable time to correct it. If the operator does not fix it, the inspector can suspend or revoke the gas well permit, and work stops during a suspension apart from efforts to remedy the default or protect safety. Appeals go to the city manager within 30 days of the written decision. Under § 13-523, each violation is a misdemeanor fined under section 1-8 for public health violations, per act and per day, and the city can add other criminal and civil remedies.

This is one of the stricter rules in Grand Prairie's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

The Bottom Line

Grand Prairie's noise from specific sources rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Grand Prairie is broadly strict or permissive.

These rules come from Grand Prairie's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
