Noise Regulations in Idaho
Overview
Idaho has no statewide noise statute. Noise regulations are set by cities and counties. Boise has the most detailed noise code, but enforcement statewide is generally lenient.
Residential Noise Limits
In Idaho, the typical residential noise limit is 65 dB during the day and 55 dB at night. These limits are measured at the property line of the receiving property using the A-weighted decibel scale (dBA). Some jurisdictions within Idaho use a "plainly audible" standard instead of or in addition to specific decibel measurements.
Quiet hours — the period when stricter nighttime limits apply — run from 10:00 PM to 7:00 AM in most Idaho jurisdictions. During these hours, activities that generate noise above the nighttime limit may result in a citation. Exemptions typically apply to emergency services, emergency repairs, and certain agricultural operations.
Construction Noise
Construction in Idaho is generally permitted from 7:00 AM to 6:00 PM on weekdays. Some cities allow Saturday construction with shorter hours (often 8:00 AM to 5:00 PM), while Sunday and holiday construction is typically prohibited in residential areas. Emergency construction and utility repairs are usually exempt from time restrictions.
Fines and Penalties
Noise ordinance violations in Idaho typically carry fines ranging from $50-$300. First-time offenders usually receive a warning or the minimum fine. Repeat offenders face escalating penalties. In some jurisdictions, chronic noise violations can be classified as misdemeanors, and equipment generating the noise may be subject to seizure. Commercial establishments that repeatedly violate noise codes may face license suspension or revocation.
