Grapevine, TX Noise Ordinances: Decibel Limits (2026)

Grapevine's noise ordinance in Chapter 18 relies primarily on the plainly audible standard rather than numeric decibel thresholds. The ordinance asks whether a sound is plainly audible at an adjoining property or inside a neighboring dwelling; if yes and the time of day qualifies, the sound is a disturbance. State law TX Penal Code 42.01 (Disorderly Conduct) supplements the local rule with an 85 dB threshold measured at the listener's position for unreasonable noise, and requires that an officer first warn the responsible party before issuing a citation. In practice, Grapevine Police officers responding to complaints in neighborhoods like Silver Lake, Stone Myers Ranch, Placid Peninsula, and downtown Main Street will document the audibility from the complainant's property and only pull out a calibrated meter for contested or commercial cases. For reference, normal conversation runs about 60 dB, a lawn mower 85 to 95 dB, and a nearby motorcycle 95 to 100 dB. Industrial zones near SH 121 and light manufacturing along Hall Johnson can operate at higher levels during daytime but must meet adjacent residential-district standards at the property line. HOA covenants often impose stricter numeric limits in upscale communities.
