Keller, TX Noise Ordinances: Decibel Limits (2026)

Keller enforces noise through a dual framework: a plainly audible test (sound audible at a neighboring property or inside a neighboring dwelling that disturbs a reasonable person) and numeric decibel limits measured at the receiving property line. The ordinance, found in Chapter 54 of the Keller Code of Ordinances, contains tables tied to the zoning of the receiving parcel, with the most protective thresholds applied when the receiver is a residential property. In practice, daytime residential-boundary limits fall in the low 60s dBA and nighttime limits drop to the mid 50s dBA, with additional reductions applied for pure tones or impulsive sounds.

01 sets a statewide backstop at 85 decibels for disorderly-conduct noise citations and requires a peace officer to give a prior warning before a citation can issue; Keller officers routinely use that state-law process in parallel with the city ordinance. Code Compliance and Keller Police use calibrated Type 2 sound-level meters when building enforceable measurements, with A-weighting and slow response as the default. Common measured complaint sources include car stereos, HVAC chillers, industrial fans, late-night patio crowds, and construction equipment. Violations can carry Class C misdemeanor fines up to 500 dollars per incident, rising to 2,000 dollars per day when health or safety is implicated.
