Mobile's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Mobile, Alabama, there are 7 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Amplified Music & Outdoor Sound

Mobile, Alabama (Mobile County) bars playing radios or other sound-reproducing devices on public streets, sidewalks, and parks loud enough to be plainly audible 25 feet away.

Key details: Distance threshold: 25 feet plainly audible. Fine: $160 plus court costs. Alt. penalty: Up to 6 months community service. Exempt: City-authorized events, emergency vehicles.

Fine of $160 plus court costs and/or up to six months' community service, at the judge's discretion, under Sec. 39-96(c).

Decibel Limits

Mobile, Alabama (Mobile County) caps sound-producing devices in residential districts at 85 db(a) from 6 a.m.-10 p.m. and 50 db(a) overnight, measured at the property line.

Key details: Daytime limit: 85 db(a), 6a-10p. Nighttime limit: 50 db(a), 10p-6a. Measured at: Residential property line. Meter standard: ANSI S1.4/S1.43, checked yearly.

Violating either the daytime (85 db(a)) or nighttime (50 db(a)) limit is unlawful and a nuisance under Sec. 39-96.1, enforced under the city's general penalty chapter.

Construction Hours

Mobile, Alabama exempts construction activity and equipment from the city's residential noise limits only between 6:00 a.m. and 9:00 p.m. under City Code § 39-96.1(d)(6). Outside that window, construction noise in or near an R-1, R-2, R-3 or R-B district falls under the same audibility and decibel limits that govern all residential noise.

Key details: Exempt hours: 6:00 a.m. to 9:00 p.m. daily, all construction equipment. Daytime limit (6 a.m.-10 p.m.): Audible 50 ft from property line or exceeds 85 db(a). Nighttime limit (10 p.m.-6 a.m.): Audible 25 ft from property line or exceeds 50 db(a). Governing section: Mobile City Code § 39-96.1(d)(6). Maximum fine: Up to $500.00 per offense, § 1-21.

A construction-noise violation is a municipal ordinance offense under City Code § 1-21: on conviction, a fine of up to $500.00, plus a discretionary jail or hard-labor term of up to six months. Every day the violation continues counts as a separate offense, so equipment run past 9:00 p.m. or 10:00 p.m. night after night can be charged repeatedly. Mobile Municipal Court hears the case; no permit or advance notice to police is required to run equipment within the exempt hours.

Leaf Blower Rules

Mobile exempts leaf blowers and other domestic power equipment from its noise limits only between 6:00 a.m. and 9:00 p.m.; outside that window the general residential noise limits apply.

Key details: Exempt hours: 6:00 a.m. to 9:00 p.m.. Covers: domestic power equipment, incl. leaf blowers. After 9pm/before 6am: general noise limits apply. Governing section: Sec. 39-96.1(d)(7).

Punishable under Chapter 1, Article II, City Code (1991); repeat nuisance complaints can draw a police response and citation.

The rules around leaf blower rules in Mobile lean permissive, but that does not mean anything goes.

Barking Dogs

Mobile treats habitually barking, crowing, or yelping animals that cause unreasonable annoyance to neighbors as a public nuisance under City Code § 7-21.

Key details: Standard: Habitual disturbing noise. Includes: Barking, crowing, yelping, whining. Fine: $100 plus court costs. Governing section: Mobile City Code § 7-21.

Failing to control a habitually noisy animal is a chapter 7 violation carrying the general $100 fine plus court costs published in the municipal court's fine schedule.
