Full Breakdown

City Code § 11-402(1)(g) prohibits discharging the exhaust of a steam engine, stationary internal-combustion engine, motor vehicle, or boat engine into the open air unless it passes through a muffler or other device that effectively prevents loud or explosive noise. A stationary generator runs on an internal-combustion engine, so it falls under this exhaust-discharge clause: an unmuffled or loud generator is treated as a prohibited noise the same as any other violation of the anti-noise ordinance, enforced on a complaint basis by Hendersonville Police.

Violations & Fines

Running a stationary engine or generator without effective muffling is a municipal-code violation under the anti-noise ordinance; Municipal Court sets the fine.

Frequently Asked Questions

Does Hendersonville regulate generator noise?
Yes, indirectly, § 11-402(1)(g) requires any stationary internal-combustion engine, which includes generators, to discharge exhaust through a muffler that prevents loud or explosive noise.
Is there a generator-specific decibel limit?
No dedicated number for generators; the exhaust-discharge clause bars loud or explosive noise generally, and separate business-noise dB limits apply near residential zones under § 11-403(3).
