Miami-Dade quiet hours are 11 PM-7 AM — sound from radios, TVs, or musical devices plainly audible 100 ft from the source is prima facie a violation of County Code §21-28. A 2023 amendment also bans construction equipment near residences 8 PM-7 AM. Civil fines start around $250.
Miami-Dade's noise rules in unincorporated areas turn on audibility, not decibel meters. Under County Code §21-28, sound from radios, TVs or musical devices that is plainly audible 100 feet from the source between 11 p.m. and 7 a.m. is prima facie evidence of a violation — the officer needs distance, not special equipment. A 2023 amendment added construction limits, banning construction equipment near residences from 8 p.m. to 7 a.m. Complaints in unincorporated areas go to Miami-Dade Police's non-emergency line; incorporated cities enforce their own ordinances.
Civil fines start around $250 and run up to $500 per violation.
