How Gaithersburg Handles Noise Ordinances: A Practical Guide

Gaithersburg maintains 95 local ordinances across all categories, and 4 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Gaithersburg falls on the strict-to-permissive spectrum compared to other cities.

Amplified Music & Outdoor Sound

Gaithersburg's City Code makes it unlawful to play radios, stereos or television sets between 10:00 p.m. and 8:00 a.m. if the sound carries beyond the dwelling unit, or beyond the nearest property line for outdoor speakers. Separately, any loudspeaker broadcasting onto a public street needs a city manager permit, and a mobile sound truck needs its own permit that bars commercial advertising outright.

Key details: Radio/stereo curfew: 10:00 p.m. to 8:00 a.m., audible beyond property line. Power equipment hours: 9:00 p.m.-7:00 a.m. weekdays; 9:00 p.m.-9:00 a.m. weekends. Loudspeaker permit: Required from city manager under § 15-5. Sound truck permit: Required under § 15-14; commercial ads barred. Penalty: Misdemeanor: up to $500 fine or 90 days jail.

Section 15-19 makes any violation of Chapter 15, including the noise and amplified-sound rules, a misdemeanor rather than a civil municipal infraction. Under the chapter's general penalty in Section 1-7, a conviction carries a fine of up to $500, up to 90 days in jail, or both, and each day the noise continues is a separate offense. Police may issue a citation under Section 1-8 in lieu of arrest.

Barking Dogs

Continued, repeated barking, howling or whining from a dog (or other animal) that causes unreasonable annoyance or disturbance to neighbors is declared an 'animal public nuisance' under City Code § 4-4(a)(3), enforced by the animal control officer regardless of what species is making the noise.

Key details: Governing section: City Code § 4-4(a)(3). Covers: Dogs, cats, fowl, pigeons, rabbits. Standard: Continued/repeated noise causing unreasonable annoyance. Enforcement: Animal control officer + animal control board. Extra remedy: City may seek injunctive relief, § 4-2(b).

A sustained barking or noise nuisance under § 4-4(a)(3) is a municipal infraction enforceable under § 1-9 pursuant to § 4-2(a), with the maximum penalty for each initial and repeat violation set by city council resolution and each incident treated as a separate offense. The animal control board may impose an administrative charge in addition to any citation, and the city may seek injunctive or mandamus relief under § 4-2(b) to stop an ongoing nuisance.

Vehicle Noise

Gaithersburg bans operating a motor vehicle or motorcycle, or discharging noise from one, in a way that disturbs residents' peace and quiet, expressly covering engine, exhaust and tire noise, blaring music and improper horn use. City Code Section 15-8(c) is part of the same disturbing-the-peace ordinance that regulates lawn equipment and outdoor stereos.

Key details: Governing section: City Code § 15-8(c). Covers: engine, exhaust, tire noise, music, horn. Hours: none fixed; disturbance standard anytime. Maximum fine: $500 (§ 1-7). Maximum jail term: 90 days.

A Section 15-8(c) violation is a misdemeanor under Section 15-19, carrying a fine of up to $500, up to 90 days in jail, or both, under Section 1-7. The ordinance applies around the clock since it sets no restricted hours, only a disturbance-of-the-peace standard.

Leaf Blower Rules

Gaithersburg restricts lawnmowers, power tools and other power-driven labor-saving devices, the category that covers gas leaf blowers, to between 7:00 a.m. and 9:00 p.m. on weekdays and between 9:00 a.m. and 9:00 p.m. on weekends and federal holidays whenever the noise carries past the nearest property line. City Code Section 15-8(a) exempts emergency repairs approved by the city manager.

Key details: Governing section: City Code § 15-8(a). Weekday hours allowed: 7:00 a.m. to 9:00 p.m.. Weekend/holiday hours allowed: 9:00 a.m. to 9:00 p.m.. Standard: audible beyond nearest property line. Exception: city-manager-approved emergency repairs.

Running power equipment outside the permitted hours audibly beyond the property line is a misdemeanor under Section 15-19, punishable by a fine of up to $500, up to 90 days in jail, or both, per Section 1-7. Landscaping contractors as well as homeowners can be cited for the same violation.

The Bottom Line

Gaithersburg's noise ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Gaithersburg is broadly strict or permissive.
