Full Breakdown
County code bars operating a musical instrument, exterior loudspeaker, or sound amplifier louder than needed for voluntary listeners on the property where it plays. Running it plainly audible off-site between 9:00 p.m. and 7:00 a.m. is prima facie evidence of a violation. A separate decibel table (Sec. 67.306) caps sound crossing a property line by land use: 60 dB(A) daytime/55 dB(A) nighttime in residential areas, 65/60 dB(A) commercial. Community events like festivals are exempt only if they end by 11:00 p.m.; later events need a Board of Zoning Adjustment variance under Sec. 67.308.
Violations & Fines
Code inspectors cite under F.S. ch. 162; civil fines run $100 first offense, $300 second, $500 third and beyond, with a $50 discount for not contesting.
