Amplified music rules in Montgomery County, MD — also called sound permit, PA system, or live music ordinances — set decibel limits, time-of-day restrictions, and when permits are required.
Montgomery County regulates amplified music and sound under Chapter 31B. Amplified sound audible beyond property lines in residential areas may constitute a violation, especially between 9 PM and 7 AM. Special event permits are available for outdoor amplified music at festivals and gatherings.
MoCo Code Chapter 31B regulates amplified music, loudspeakers, and sound-amplification devices in unincorporated areas. Amplified sound from residences, vehicles, or outdoor venues that is plainly audible beyond the property line of the source may constitute a noise violation, with stricter enforcement during nighttime hours from 9 PM to 7 AM. Outdoor events with amplified music require a special events permit from the Department of Permitting Services, which includes noise conditions such as maximum decibel levels, end times, and speaker orientation away from residential properties. Commercial establishments with outdoor music or entertainment must comply with conditions set during their conditional use approval. The county has seen increased complaints about amplified music from backyard parties in densely populated areas like Silver Spring and Wheaton. Vehicle sound systems audible at a distance are also covered. Montgomery County Police respond to amplified music complaints during nighttime hours.
