Miami regulates HVAC equipment noise under Chapter 36 general noise provisions. Mechanical equipment noise plainly audible at 100 feet from the property line violates Section 36-4. Nighttime readings (10 PM-7 AM) receive a 10 dB(A) penalty before averaging. Equipment must have functioning mufflers.
HVAC equipment noise in Miami falls under Chapter 36 of the Code of Ordinances. Section 36-4 establishes that noise from mechanical devices (including HVAC systems, compressors, and condensers) that is plainly audible at 100 feet from the property line constitutes prima facie evidence of a violation. The ordinance distinguishes between daytime (7 AM to 10 PM) and nighttime (10 PM to 7 AM) noise, with nighttime readings increased by 10 dB(A) before averaging. HVAC equipment must have functioning mufflers and sound attenuators. The city's zoning code (Miami 21) includes setback and screening requirements for mechanical equipment in residential areas. Rooftop HVAC units on commercial buildings near residential zones face enhanced scrutiny. Code Compliance investigates complaints through on-site sound measurement. Miami-Dade County's minimum noise standards also apply. New HVAC installations are reviewed during the building permit process for noise code compliance.
Sec. 36-4 noise violation citation. Code Compliance enforcement action. Building code violation for improper installation. Abatement orders for persistent noise.
