Jupiter, FL Noise Ordinances: Decibel Limits (2026)

Table 1 of § 13-144 fixes the town's baseline exterior sound limits by sound zone and time of day, each measured as a three-minute equivalent continuous sound level (Leq): a residential sound zone is capped at 55 dBA from 7:00 a.m. to 10:00 p.m. and 45 dBA from 10:00 p.m. to 7:00 a.m.; a mixed-use zone at 60/50 dBA; a commercial zone at 65/55 dBA; and an industrial zone at 70/60 dBA. Sound zones are assigned property by property under § 13-142: residential, conservation, and public or quasi-public institutional districts, plus MXD neighborhood subdistricts, are treated as residential sound zones, while other commercial, mixed-use and industrial districts get their own zone designation.

Subsection (b) makes it unlawful for anyone to create sound on property they own, lease or control that exceeds either the Table 1 (or Table 2, for a certified outdoor venue) standard measured at any other property line, or a maximum instantaneous peak that is ten dBA above the applicable standard for sound from mechanical equipment. If the measurement point sits on the boundary between two different sound zones, § 13-144(c) requires using the logarithmic dBA average of the two zones' standards from Table 3, unless the zones are separated by another property, a right-of-way or a waterway, in which case no averaging applies.

Certified outdoor venues get an extended, higher schedule under Table 2, allowing operation an extra hour, until midnight, at the standard levels, with a transitional lower standard from 11:00 p.m. to midnight and the strictest standard only after midnight.
