In my county, they fall under the Noise Control ordinance:
When does the Noise Control Ordinance take effect?
The Noise Control Ordinance adopted by the County Board of Commissioners went into effect June 1, 2021.
What sounds are regulated by the ordinance?
The following sounds are regulated by the ordinance:
Mechanical sound making devices such as radios, stereos, speakers, loudspeakers, soundbars, televisions, musical instruments, horns, whistles, bells, chimes or carillons, phonographs, amplification devices, or other machines or devices for the producing, reproducing, or amplifying of sound;
Human-produced sounds such as yelling, shouting, hooting, whistling, singing, speaking, or arguing;
Impulsive sound;
Party and event noise;
Testing of burglar, fire, or car alarms; and
Sound coming from construction and demolition activities, machines, or electrical generators.
How are sounds regulated under the ordinance?
Under the Noise Control Ordinance, sounds are regulated by location, time, and distance using the plainly audible standard.
How are fireworks addressed in the Noise Control Ordinance?
State law preempts the County’s regulation of sound from fireworks on January 1, the last Saturday and Sunday in May, July 3, July 4, the first Monday in September, and December 31 and only authorizes the County to regulate the sound from consumer fireworks as part of general noise regulation. Under the County’s Noise Control Ordinance, consumer fireworks are exempted on the days and times specified in state law. At all other times, the sound from consumer fireworks is regulated by the Noise Control Ordinance and subject to the same time, distance, and location restrictions as other impulsive sounds.
What if I am holding a special event that might exceed the sound limits in the ordinance?
The Noise Control Ordinance includes a noise permit process whereby event organizers can obtain a noise permit for events of short duration upon approval of a noise permit application by the Department of Planning and Development.
