Summary
Gaithersburg's City Code makes it unlawful to play radios, stereos or television sets between 10:00 p.m. and 8:00 a.m. if the sound carries beyond the dwelling unit, or beyond the nearest property line for outdoor speakers. Separately, any loudspeaker broadcasting onto a public street needs a city manager permit, and a mobile sound truck needs its own permit that bars commercial advertising outright.
The playing or operation of radios, stereos, television sets or similar devices between the hours of 10:00 p.m. and 8:00 a.m. which are audible beyond the confines of the dwelling unit within which such sound is played or relayed; or if such devices are placed or operated in an outdoor area, which are audible beyond the nearest common property line at the hours specified herein.

Full Breakdown
Section 15-8, Disturbing the Peace, lists categories of noise the city treats as public nuisances. Subsection (a) restricts lawnmowers, power tools, bulldozers and other power-driven equipment to 7:00 a.m. to 9:00 p.m. on weekdays and 9:00 a.m. to 9:00 p.m. on weekends and federal holidays, unless the city manager approves an exception for emergency repairs. Subsection (b), the amplified-sound rule, bars radios, stereos and televisions from 10:00 p.m. to 8:00 a.m. if they can be heard beyond the dwelling unit, or beyond the nearest common property line when the equipment sits outdoors. Subsection (c) separately targets vehicle and motorcycle noise, including engine, exhaust, tire and horn noise used to disturb the peace.
Two more sections in the same chapter regulate amplification devices before they are even turned on. Section 15-5 requires anyone operating a loudspeaker, radio or other sound-producing device that broadcasts onto the public streets to first obtain a permit from the city manager. Section 15-14 requires a separate permit for any sound truck or other mobile amplification device operated within the city, and it flatly bars the city manager from issuing that permit for commercial advertising purposes. A special-events permit under Section 15-8.1 additionally requires organizers to submit a live entertainment, concert or amplified music design plan when applying to hold an outdoor event on private property.
Together the sections mean a resident cannot run outdoor speakers or a stereo audible off the property overnight, a business cannot broadcast onto the street without city sign-off, and no one may drive a sound truck through Gaithersburg for advertising regardless of the hour.
Violations & Fines
Section 15-19 makes any violation of Chapter 15, including the noise and amplified-sound rules, a misdemeanor rather than a civil municipal infraction. Under the chapter's general penalty in Section 1-7, a conviction carries a fine of up to $500, up to 90 days in jail, or both, and each day the noise continues is a separate offense. Police may issue a citation under Section 1-8 in lieu of arrest.
