St. Petersburg, FL Noise from Specific Sources: HVAC & Mechanical Noise (2026)

Section 11-53(13) singles out mechanical equipment, pool pumps, air conditioning units and air-handling systems, for a standard built around equipment condition rather than a fixed clock. " Unlike nearly every other subsection of Section 11-53, this one carries no exempt daytime window and no nighttime/daytime split, the 100-foot threshold applies around the clock, because the trigger is a maintenance failure (a compressor, fan or pump running rough or unmaintained) rather than ordinary operation. A properly maintained air handler that happens to be audible at 100 feet is not, by the plain text, a violation; the rule targets equipment that is out of good working condition.

That distinction matters for enforcement: a code officer responding to an HVAC noise complaint has to find both that the sound carries 100 feet or more and that the unit is not in good working order, which typically means documenting rattling, worn bearings, a failing compressor or a similar mechanical defect rather than simply a loud but functioning system.
