Knox County has no ordinance restricting leaf blowers by decibel, model, or time of day. Lawn-maintenance noise is not separately regulated in the unincorporated county; only nuisance-level noise falls under state disorderly-conduct law.
Nothing in the Knox County Code of Ordinances or Zoning Ordinance singles out leaf blowers, gas-powered garden equipment, or yard-maintenance hours. The zoning noise performance standards (4.10.01) generally exempt short-duration and mobile-equipment noise, and there is no county quiet-hours rule. Residents bothered by persistent equipment noise would rely on Tennessee's disorderly-conduct statute (TCA 39-17-305). Municipalities such as Knoxville may regulate such noise separately, but those rules do not apply to unincorporated Knox County.
No county leaf-blower penalty. Persistent nuisance noise could be cited under TCA 39-17-305 (Class C misdemeanor).
