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.
Unlike many cities that set specific decibel thresholds by zoning district and time of day, Denton Code Sec. 17-20 primarily uses a subjective reasonableness test -- noise is prohibited when it is of such character, intensity, and duration as to substantially interfere with comfortable enjoyment of private homes or cause material distress to a reasonable person of normal sensibility. The single numeric standard in the code is 70 dBA at the established event perimeter for outdoor amplified events and sound systems. All measurements use the A-weighted decibel scale (dBA) with a minimum two-minute measurement period at the location of the complaining party. Officers responding to noise complaints may use sound level meters but can also issue citations based on officer observation without instrumented measurement. The Texas Penal Code Sec. 42.01 (Disorderly Conduct) provides statewide backup enforcement for unreasonable noise as a Class C misdemeanor with fines up to $500.
Class C misdemeanor under local or state law. Fine up to $500 per offense.
