Noise Ordinances in Fort Smith, AR

If you live in Fort Smith or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Fort Smith has 5 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.

Leaf Blower Rules

Fort Smith treats leaf blowers and other lawn equipment as a 'transient sound source' and caps their peak noise at 20 decibels above the zone's standard limit rather than banning specific hours.

Key details: Covered equipment: Lawn equipment, power tools. Peak limit: +20 dB over zone base. Residential day base: 60 dB(A). Residential night base: 55 dB(A).

Exceeding the transient-source decibel cap is a noise disturbance misdemeanor under § 16-43, punishable per the general penalty in § 1-9.

Barking Dogs

Fort Smith cites owners whose dogs bark or howl loudly enough to disturb neighbors, using a three-complaints-in-90-days threshold by day and direct officer observation at night.

Key details: Daytime hours: 7 a.m.-10 p.m.. Daytime threshold: 3+ complaints in 90 days. Nighttime hours: 10 p.m.-7 a.m.. Nighttime threshold: One officer-observed incident.

A verified nuisance-barking citation is issued to the dog's owner or keeper; nighttime violations need only one officer-observed incident rather than the daytime three-complaint threshold.

Amplified Music & Outdoor Sound

Amplified music or sound equipment that's plainly audible 150 feet away between 11:00 p.m. and 7:00 a.m. is automatically deemed an unlawful noise disturbance in Fort Smith.

Key details: Restricted hours: 11:00 p.m.–7:00 a.m.. Audibility test: 150+ feet, plainly audible. Daytime rule: Zone decibel limits apply (§ 16-45). Exempt: Permitted special events, religious bells.

Amplified sound plainly audible 150+ feet away between 11:00 p.m. and 7:00 a.m. is a noise disturbance misdemeanor under § 16-43, punishable per § 1-9.

Fort Smith caps ambient noise by zone and time: 60 dB(A) day / 55 dB(A) night in residential areas, and 75 dB(A) day / 70 dB(A) night in commercial zones.

Key details: Residential daytime cap: 60 dB(A). Residential nighttime cap: 55 dB(A). Commercial daytime cap: 75 dB(A). Commercial nighttime cap: 70 dB(A). Measured at: Property boundary of the source.

Exceeding the applicable zone's decibel ceiling is a misdemeanor under Sec. 1-9; readings are taken with a calibrated Type II sound level meter per Sec. 16-44.

Construction Hours

Construction projects in Fort Smith must stay within industrial-zone noise limits, 80 dB(A) daytime, 75 dB(A) at night, for as long as the building permit allows work.

Key details: Daytime limit: 80 dB(A), 7 a.m.–11 p.m.. Nighttime limit: 75 dB(A), 11:01 p.m.–6:59 a.m.. Allowed hours set by: The building permit itself. Penalty: Misdemeanor under Sec. 1-9.

Exceeding the industrial-zone decibel limits during permitted work, or operating outside the building permit's authorized hours, is a misdemeanor under Sec. 1-9; each day counts separately.
