Chattanooga prohibits operating lawn mowers, leaf blowers, weed-eaters, chain saws or other domestic tools outdoors between 9:00 p.m. and 7:00 a.m. Daytime use is allowed. There is no separate decibel limit for these tools.
City Code Sec. 25-68(a)(12) lists lawn mowers, leaf blowers, weed-eaters, chain saws or other domestic tools among prohibited noises when operated out-of-doors between 9:00 p.m. and 7:00 a.m. The rule is a time restriction rather than a decibel or gas-vs-electric restriction, so daytime yard work is permitted. Unincorporated Hamilton County has no equivalent countywide leaf-blower ordinance; the general Tennessee nuisance and disorderly-conduct framework applies there, and each incorporated city sets its own hours. Refuse collection using a mechanical loader is separately barred 9 p.m.–7 a.m. near residential zones under Sec. 25-68(a)(11).
$50 citation fine per violation, plus civil penalty up to $500 per violation in Chattanooga city court (Sec. 25-73).
