West Palm Beach, FL Noise from Specific Sources: HVAC & Mechanical Noise (2026)

West Palm Beach doesn't set a separate decibel limit just for air conditioners or condenser units; instead, HVAC equipment is regulated the same way as any other sound source under the general noise disturbance ordinance in § 34-36, and the code specifically walks through how to apply that ordinance to HVAC noise. Section 34-35 defines real property line, the boundary at which sound is measured for compliance, to cover three situations: the lot line between separate parcels, the walls of a unit inside a multi-dwelling building, and, for a mixed-use property with different activities stacked in one building, the interface between those uses.

The definition gives HVAC equipment as its worked example, stating that if there is an outdoor sound source such as an HVAC unit on the same parcel of property, the boundary line is the exterior wall of the receiving unit. In practice, that means a rooftop or ground-mounted condenser serving a commercial tenant is measured against the exterior wall of the residential or other unit it is disturbing, not against the outer property line of the whole building, when a complaint is filed. Once a complaint identifies HVAC noise as plainly audible and unreasonable at that boundary, it is evaluated under the general disturbance factors in § 34-36(a)(1), including volume, duration, time of day and whether it disturbs a neighbor's repose.

Section 34-36(a)(1)(i) specifically lets an officer count perceptible vibration from a low-frequency source, which covers compressor hum, toward the violation. 00 for repeat violations under § 34-45.
