Miami, FL Noise from Specific Sources: Generator Noise (2026)

Generator noise in Miami falls under the general noise provisions of Chapter 36. Section 36-4 applies the 100-foot plainly audible standard to mechanical devices including generators. Portable generators and permanently installed standby generators that produce noise audible at 100 feet from the property line or 150 feet from a non-stationary source are subject to violation. Nighttime operation between 10 PM and 7 AM receives a 10 dB(A) penalty before averaging, making compliance more difficult during quiet hours. Given Miami's vulnerability to hurricanes, emergency generator operation during declared emergencies and power outages is generally exempt from noise restrictions. Florida Building Code requires permanent standby generators for certain building types and occupancies in the High-Velocity Hurricane Zone (Miami-Dade and Broward Counties). Generator installations require building permits and must comply with zoning setback requirements. Code Compliance handles noise complaints at 305-416-2087.
