Davis County, UT Noise Ordinances: Decibel Limits (2026)

Unlike some cities, Davis County jurisdictions largely use qualitative standards rather than a residential decibel chart. Bountiful City Code 8-7-101 prohibits 'unreasonably loud noises' that disturb a person of average sensitivities, and Layton uses a 'plainly audible at the property boundary' test. The one clearly numeric standard is Bountiful City Code 13-1-117 for motor vehicles: sound pressure level may not exceed 88 dB(A) for a vehicle over 10,000 lbs GVWR or 80 dB(A) for 10,000 lbs or less, measured by a sound level meter 25 feet away at a height of at least four feet. So for everyday neighbor noise, expect a subjective disturbance standard rather than a meter reading.
