Denton's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Denton, Texas, there are 9 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Decibel Limits

Denton Sec. 17-20 uses a reasonableness standard rather than fixed decibel limits for most noise sources. The one specific numeric limit is 70 dBA at the event perimeter for outdoor amplified events. Measurements use the A-weighted scale over a minimum two-minute period. No separate residential vs. commercial dBA thresholds are codified.

Key details: Code: Sec. 17-20 (Ch. 17, Art. II). Outdoor Events: 70 dBA at event perimeter. Measurement: A-weighted, 2-min minimum. General Standard: Reasonableness test (no fixed dBA). State Backup: TX Penal Code Sec. 42.01.

Class C misdemeanor under local or state law. Fine up to $500 per offense.

Aircraft Noise

Denton Enterprise Airport (DTO) is a city-owned general aviation facility within city limits. Aircraft noise is federally regulated under FAA Part 150 and the Airport Noise and Capacity Act of 1990. The city has no local aircraft noise ordinance because FAA rules preempt municipal regulation of aircraft in flight.

Key details: Airport: Denton Enterprise Airport (DTO). Jurisdiction: FAA federal preemption. Local Ordinance: None -- federally preempted. Airport Manager: (940) 349-7750. Zoning: Airport overlay per DDC.

No local penalty -- aircraft noise is federally preempted. Ground maintenance noise: Sec. 17-20 applies.

Denton is more permissive than most cities when it comes to aircraft noise. That said, there are still limits.

Industrial Noise

Denton regulates industrial noise through Sec. 17-20 general noise provisions and the Denton Development Code zoning buffers. Industrial and manufacturing zones require screening and buffering when adjacent to residential districts. TCEQ enforces statewide air quality and nuisance standards for industrial facilities.

Key details: Local Code: Sec. 17-20 general noise standard. Zoning Buffers: DDC Subchapter 5 & 7. State Agency: TCEQ (TX Health & Safety Ch. 382). I-35 Corridor: Major industrial activity zone. Railroad Noise: Federally preempted.

Leaf Blower Rules

As of January 1, 2025, Sec. 17-40(k) prohibits blowing yard waste into public streets. Commercial landscaping crews must follow construction-hour time limits.

Key details: Dedicated Ban: None -- no leaf blower ban. Noise Standard: Sec. 17-20 unreasonableness test. Street Blowing: Prohibited (Sec. 17-40(k), eff. Jan 2025). Commercial Hours: Same as construction hours. Enforcement: Community Improvement Services.
