If you live in Port St. Lucie or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Port St. Lucie has 6 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.

Quiet Hours

Port St. Lucie sets decibel-based nighttime limits under Code of Ordinances Chapter 94: in residential areas the maximum drops to 55 dBA/60 dBC between 11:00 p.m. and 7:00 a.m., and these nighttime limits also apply all day on Sundays and holidays.

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.

Construction Hours

Section 94.05(n) exempts construction noise between 7:00 a.m. and sundown once a building permit is issued. Work generating noise between sundown and 7:00 a.m. needs a special permit under Section 94.07.

Section 94.08(d) sends penalties to Chapter 37, where Section 37.09 allows fines up to $1,000 per day for a first violation and $5,000 per day for a repeat; noise violations are declared irreparable.

Barking Dogs

Sec. 92.09 bans keeping an animal outdoors that barks, howls or similar between 11:00 p.m. and 6:00 a.m., or that does so repetitively and habitually for five minutes or more. Indoor animals are covered by a 100-foot plainly audible test.

Key details: Code Section: Sec. 92.09 (Noisy animals prohibited). Night window: 11:00 p.m. to 6:00 a.m.. Daytime trigger: Five minutes, gaps under thirty seconds. Indoor animals: Plainly audible at 100 feet. First-offense fine: $50 plus $5 surcharge.

A law enforcement or animal control officer may issue a citation. Under Sec. 92.99 the fine is $50 first offense, $100 second, and $200 plus a mandatory court appearance for a third, each with a $5 surcharge.

Vehicle Noise

Port St. Lucie bans sounding a vehicle horn continuously for more than 30 seconds and car audio plainly audible 25 feet away. General motor-vehicle noise is exempted to the extent Florida Statutes chapters 316 and 403 specify.

Key details: Horn limit: 30 seconds, except danger warning. Car stereo: Not plainly audible at 25 feet. Alarm curfew: No intentional alarms 10 p.m. to 7 a.m.. Alarm testing: 30 seconds maximum, any time. Engine and exhaust noise: Exempt per F.S. chs. 316, 403.

Sec. 94.08 puts enforcement with code enforcement officers and sets penalties under Chapter 37. It also declares all violations irreparable, which under Sec. 37.09 supports a fine of up to $15,000 per violation.

Amplified Music & Outdoor Sound

Port St. Lucie bans loudspeakers and amplifiers in or next to residential areas from 10:00 p.m. to 7:00 a.m. on weekdays and 10:00 p.m. to 10:00 a.m. on weekends and holidays when the sound carries across your property line.

Key details: Code Section: Sec. 94.06(c). Weekday curfew: 10:00 p.m. to 7:00 a.m.. Weekend and holiday curfew: 10:00 p.m. to 10:00 a.m.. Residential daytime limit: 60 dBA / 65 dBC. Special permit: $25.00 fee, ten consecutive days maximum.

Chapter 94 is enforced through Chapter 37. Section 94.08(c) treats noise violations as irreparable, so section 37.09(a)(1) allows a fine up to $15,000.00 per violation; a Chapter 37 citation is a civil infraction capped at $500.00.

This is not one of those rules that cities tend to ignore. Port St. Lucie actively enforces its amplified music & outdoor sound requirements.

Aircraft Noise

Port St. Lucie's noise chapter expressly exempts noise from operating any aircraft, so overflight noise cannot be cited under Chapter 94. Model aircraft and drones are not exempt, and Chapter 91 still limits where aircraft may land.

Key details: Aircraft exemption: Sec. 94.05(d) exempts aircraft noise. Drones and models: Not exempt; Sec. 94.06(e) applies. Model vehicle hours: Sundown to 7:00 a.m. weekdays. Measurement distance: Not closer than 100 feet. Where aircraft may land: Designated landing fields or helipads only.

Aircraft overflight noise cannot be cited. Model-vehicle and other noise violations are enforced under section 94.08 through Chapter 37, where the Special Magistrate may fine up to $1,000.00 per day for a first violation.

Port St. Lucie is more permissive than most cities when it comes to aircraft noise. That said, there are still limits.
