Outdoor music in Gaithersburg must comply with noise ordinance decibel limits at property boundaries. Live and recorded music outdoors during nighttime hours faces stricter limits. The city hosts regulated outdoor music at venues like Bohrer Park and the Kentlands Arts Barn with permitted sound levels.
Outdoor music in Gaithersburg — whether live performances, DJ sets, or recorded music — must comply with Montgomery County Code Chapter 31B decibel standards. Music audible beyond property boundaries must not exceed 65 dBA at residential receiving property lines during daytime or 55 dBA during nighttime. Restaurants and businesses with outdoor seating areas that play music must control volume to remain within these limits. The city supports outdoor cultural events through its Parks, Recreation, and Culture department, permitting music at Bohrer Park Amphitheater, Kentlands Arts Barn, and festival spaces in Olde Towne. Permitted events receive time-limited exemptions from standard noise limits but must still comply with permit conditions including cutoff times. Residential outdoor gatherings with music should be mindful of neighbors, especially after 9 PM when nighttime limits apply. Acoustic performances and unplugged music typically do not trigger noise complaints but amplified setups with subwoofers can easily exceed limits at property boundaries.
Violations carry fines from $100 to $500. Permitted events exceeding their conditions may lose future permit eligibility. Repeat residential violations escalate through the county enforcement process.
