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

The exemption sits in section 18-3(g)(1) of the noise limitations section, which lists the uses and activities exempt from noise level regulations. Item (1) names air conditioners and lawn mowers and attaches a three-part condition: the equipment must be functioning in accord with the manufacturers' specifications, with all manufacturers' mufflers and noise reducing equipment in use, and with that equipment in proper operating condition. A compressor running with a missing or damaged sound-reducing part is outside the wording of the exemption.

Outside the exemption, the ordinary tools apply. Table I in section 18-3(d)(1) caps residential noise at 70 dB(A) by day and 65 dB(A) at night, and the reading is taken at any point outside the property line from where the noise is transmitted. Section 18-5(c) holds the owner, tenant, lessee, manager, overseer or agent of the property responsible for compliance, so the person in possession answers for a noisy unit even when an installer or neighbor is blamed.

Section 18-4(b) adds a second layer. The noises it lists are unlawful notwithstanding the fact that no violation of section 18-3 is involved and notwithstanding the fact that the activity complained about is exempted in section 18-3(g), and the enumeration is not exclusive. The sworn complaint requirement in section 18-4(b)(3) applies to complaints under that section.

Placement is a zoning matter. Section 34-716(a)(2) of the Land Development Code allows air conditioning compressors or other equipment designed to serve the main structure in any required rear yard, but the equipment shall not project more than three (3) feet into any required yard in a residential district. That section controls where the unit sits, while section 18-3(g)(1) controls whether its sound is exempt.
