Summary
Rock Hill's noise ordinance names blowers, power fans and internal combustion engines, the equipment category covering portable and standby generators, as a specifically prohibited noise unless the unit is muffled. § 20-162(2) requires the engine to carry 'a muffler device sufficient to deaden' the exhaust and explosion noise it produces, or its operation counts as a violation regardless of decibel level.
(2)Blowers or engines. The operation of any noise-creating blower or power fan or any internal combustion engine, the operation of which causes noise due to the explosion of operating gases or fluids, unless the noise from such blower or fan is muffled and such engine is equipped with a muffler device sufficient to deaden such noise.
Full Breakdown
City Code § 20-162(2) targets generator-type equipment directly: 'the operation of any noise-creating blower or power fan or any internal combustion engine, the operation of which causes noise due to the explosion of operating gases or fluids, unless the noise from such blower or fan is muffled and such engine is equipped with a muffler device sufficient to deaden such noise,' is declared a prohibited noise under § 20-161. ' A homeowner running an unmuffled generator during a routine outage, as opposed to true utility-restoration work by a crew, is not covered by that emergency exemption and can be cited under § 20-162(2) alone if the noise reaches a neighbor.
Violations & Fines
Running an unmuffled blower, power fan or generator engine is a citable prohibited noise under § 20-162(2), enforced through § 1-11's general penalty of up to $500.00 or 30 days in jail. The emergency-utility-restoration exemption in § 20-162(18)(c) can cover generator noise during storm recovery work, but not routine unmuffled use.
