Quiet hours in Sumner County, TN — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Tennessee fixes no countywide decibel limit, so quiet hours come from each Sumner County city. Gallatin holds residential noise to 45 decibels between 7 p.m. and 7 a.m. In unincorporated areas the Sheriff enforces the state disorderly conduct law, Tenn. Code Ann. §39-17-305.
There is no single Sumner County noise ordinance with set decibel limits; the rules are written city by city. Gallatin's ordinance caps residential and commercial noise at 45 dBA from 7 p.m. to 7 a.m. and 65 dBA the rest of the day. Hendersonville and the smaller towns handle disturbances through their own nuisance codes. Across the unincorporated county, which has no decibel ordinance, the Sumner County Sheriff enforces Tenn. Code Ann. §39-17-305, making unreasonable noise a Class C misdemeanor. Boat and party noise on Old Hickory Lake is a recurring warm-weather complaint.
Under Tenn. Code Ann. §39-17-305, unreasonable noise is a Class C misdemeanor, up to a $50 fine and 30 days. Gallatin's ordinance carries a separate fine of up to $250 or 15 days.
