Summary
Shelby exempts generator maintenance and testing from its noise ordinance only on weekdays between 9 a.m. and 4 p.m., capped at 80 dB(A), with mufflers intact and the unit kept as far from the property line as possible.
This emergency exception includes maintenance, backup or upkeep ("maintenance") strictly necessary to keep emergency equipment, such as generators, in operating order as prescribed by the manufacturer, provided such maintenance is done only on weekdays between the hours of 9:00 a.m. and 4:00 p.m. sounds created do not exceed 80 dB(A), the equipment is maintained as far from the property line as reasonably possible to serve its purpose, and the equipment has all the manufacturer's standard mufflers and noise reducing equipment intact.

Full Breakdown
Under Shelby's noise ordinance (Sec. 16-34(1)), routine maintenance, backup checks, or upkeep needed to keep emergency generators in working order is exempt from the city's general noise rules, but only on weekdays from 9:00 a.m. to 4:00 p.m., with sound capped at 80 dB(A), the unit positioned as far from the property line as reasonably possible, and the manufacturer's standard mufflers and noise-reducing equipment intact. Generator noise outside those conditions falls under the city's general 60 dB(A) limit for sound reaching an occupied residential structure under Sec. 16-36, enforced by the noise control officer.
Violations & Fines
Violating the maintenance-window conditions or the general 60 dB(A) residential noise cap brings a civil penalty starting at $100, rising to $1,000 for a fifth offense within a year, plus possible misdemeanor charges.
