Full Breakdown
Port St. Lucie regulates quiet hours through measured sound levels rather than a flat prohibition. Section 94.04 makes it unlawful to create a sound level exceeding the limits in Table I, measured at or beyond the receiving property's real property line. For residential land use the daytime limit (7:00 a.m. to 11:00 p.m.) is 60 dBA/65 dBC and the nighttime limit (11:00 p.m. to 7:00 a.m.) is 55 dBA/60 dBC; commercial is 65/70 dBA and industrial 65/70 dBC across both periods. Section 94.04(g) provides that for any sound projected on a Sunday or holiday, the more restrictive 11:00 p.m. to 7:00 a.m. limits apply all day. Section 94.04(i) independently makes noise 'plainly audible at a distance of one hundred (100) feet or more' a violation, including amplified and portable sound equipment. Loudspeaker and amplifier curfews appear separately in section 94.06(c).
Violations & Fines
Penalties for violating Chapter 94 are imposed as provided in Chapter 37 of the City Code (section 94.08(d)); each violation is also declared a nuisance under section 94.09, abatable under Ch. 60, Florida Statutes. Code enforcement officers measure sound levels with an ANSI-compliant sound level meter.
