DC Noise Laws: Quiet Hours, Decibel Limits and Penalties

The District of Columbia has its own noise code, and it runs on two clocks. Under the District's Noise Control Act regulations (20 DCMR chapters 27 and 28), nighttime is 9:00 p.m. to 7:00 a.m.; in a residential zone, noise measured at the source's property line may not exceed 60 dB(A) by day or 55 dB(A) at night, and any "noise disturbance" from music, amplifiers or voices is unlawful at any hour. The Metropolitan Police Department enforces these rules: 20 DCMR 2713.3 sets a fine of up to $1,000, up to 10 days in jail, or both, and officers may instead issue a notice of civil infraction, with civil fines that rise for repeat offenses (2713.4, 2713.5; 16 DCMR 3201, 3310). Separately, making "an unreasonably loud noise between 10:00 p.m. and 7:00 a.m. that is likely to annoy or disturb one or more other persons in their residences" is disorderly conduct, a misdemeanor punishable by up to 90 days and a $500 fine (D.C. Code 22-1321(d), (h); 22-3571.01). A 2025 amplified sound law is on the books but has not been funded. To compare other jurisdictions, see our guide to noise ordinance laws by state.

Jurisdiction scope: This article covers District of Columbia law: the noise control regulations in 20 DCMR chapters 27 and 28 issued under the District's Noise Control Act (D.C. Law 2-53, as amended); disorderly conduct and its penalty (D.C. Code 22-1321, 22-3571.01); the civil infraction classes and fines for noise violations (16 DCMR 3201, 3310); the alcohol licensee noise rule (25-725); the horn rule in 18 DCMR 730; the Council's police power over street noise (1-303.01); and D.C. Law 25-313. Code text is the codified edition published by the D.C. Council, and regulation text is from the District's official DCMR site. It does not cover federal property, aircraft or workplace noise, lease terms, or the law of Maryland or Virginia.

How noise law works in the District

The District is a single jurisdiction, so the rules that a state and a city would split elsewhere sit in one set of laws. The D.C. Council holds the police power over street noise; D.C. Code 1-303.01 includes the power "To regulate or prohibit loud noises with horns, gongs, or other instruments, or loud cries, upon the streets or public places."

The regulations open with a policy statement declaring that every person in the District is entitled to ambient noise levels that are not detrimental to life, health, and enjoyment of his or her property (20 DCMR 2700.1).

They then sort noise into two kinds of rules. Under 20 DCMR 2700.3, "The activities set forth in 2702 through 2704, and 2800 through 2807 are subject to the noise disturbance standard or other specific limitations," and "All other noise-producing activities are subject to the general decibel limitations set forth in 2701 and 2810."

Quiet hours in DC: two different clocks

Which hours apply depends on which law is being enforced:

The regulations define "Daytime" as "the hours from 7:00 a.m. to 9:00 p.m." and "Nighttime" as "the hours from 9:00 p.m. to 7:00 a.m." (20 DCMR 2799.1).

Decibel limits by zone

Section 2701 sets the general maximum sound levels:

Source: 20 DCMR 2701.1.

Where the measurement is taken matters. "For the purposes of this section, the sound level shall be measured at the property line of the property on which the noise source is located, or as close as is practicable if there is an obstruction" (2701.2). "Noise emanating from inside a motor vehicle shall be measured at a distance of not less than fifty feet (50 ft.) from the vehicle" (2701.7).

Three more rules can change the number that applies. "If a sound can be measured in a contiguous noise zone that has a more restrictive noise limitation than that from which the noise emanates, the sound level measurement at the zone line shall not exceed that established for the more restrictive zone" (2701.4). Where no maximum has been set for the area, "the maximum level shall be sixty (60) dB (A)" (2701.5). And unless another section restricts them, "sounds emanating from a street or highway shall not exceed the most restrictive sound level established for the property bordering the street or highway" (2701.6).

The noise disturbance rule: no meter needed

Music, amplified sound and loud voices are judged mainly by a reasonable-person test rather than a meter. The regulations define a "Noise disturbance" as "any sound which is loud and raucous or loud and unseemly and unreasonably disturbs the peace and quiet of a reasonable person of ordinary sensibilities in the vicinity thereof, unless the making and continuing of the noise is necessary for the protection or preservation of the health, safety, life, or limb of some person" (20 DCMR 2799.1).

In deciding whether a noise is a noise disturbance, "the Mayor shall consider the location, the time of day when the noise is occurring or will occur, the duration of the noise," and "A noise shall not be considered a noise disturbance if it is made during noncommercial public speaking during the daytime and does not exceed 80 decibels inside the nearest occupied residence in districts zoned R-1A, R-1B, R-2, R-3, or R-4" (20 DCMR 2799.1).

The same section provides: "If the noise is made at night or does not involve noncommercial public speaking, the Mayor shall not be required to measure the decibel level of the noise to find a noise disturbance."

The core prohibition for music and sound equipment is 20 DCMR 2800.2:

"It shall be unlawful for any person to make, continue, or cause to be continued any noise disturbance by the operation, use, or playing of any musical instrument or device, loud speaker, sound amplifier, or other similar device, or unamplified voice, for the production or reproduction of sound on private property or public space."

"Parades and public gatherings conducted pursuant to a permit issued by the Metropolitan Police Department (as provided for in 24 DCMR, Chapter 7) are exempt from the noise disturbance limitation" (2800.3).

Section 2704.8 separately states that "The unamplified voice shall be exempt at all times," while 2800.2 names an "unamplified voice" among the sources of an unlawful noise disturbance. The 2704 exemptions reach only the decibel limits in 2701: under 2704.1, sources in that section are exempt "from the specific noise limitations contained in § 2701 of this chapter; Provided, that no exemption shall preclude enforcement under any other section of Chapters 27 and 28 of this subtitle." So an unamplified voice is not held to the decibel table, but it can still be an unlawful noise disturbance under 2800.2.

Construction, yard work and trash trucks

Construction hours. "From 7:00 a.m. to 7:00 p.m. on any weekday, noise levels resulting from construction or demolition (excluding pile driver devices) shall not exceed a Leq(1.) of eighty (80) dB(A) unless granted a variance" (20 DCMR 2802.1). "From 7:00 p.m. to 7:00 a.m. the maximum noise levels prescribed in 2701 ... shall apply" (2802.2).

In residential areas, the rule is stricter:

"2803.2 No noise from construction, excluding minor home repairs, shall be permitted within a residential, special purpose, or waterfront zone on any Sunday or legal holiday, or after 7:00 p.m. and before 7:00 a.m. on any weekday."

The regulations define "Weekday" as "any day except Sunday or a legal holiday" (20 DCMR 2799.1), so Saturday follows the weekday rule: construction noise is allowed from 7:00 a.m. to 7:00 p.m.

That limit does not apply to "Portable power tools used for minor improvement of real and personal residential property otherwise allowable under this section" or to "Work performed by public utilities" (2803.3).

Power tools and garden equipment. Under 20 DCMR 2704.6, "The use or operation of portable power tools, home snow removal equipment, power garden excluding leaf blowers devices, and other powered equipment for minor repairs or minor improvements of real or personal residential property shall be exempt on weekdays (excluding Saturdays) during the daytime and from 9:00 a.m. to 9:00 p.m. on Saturdays, Sundays, and legal holidays." Like every 2704 exemption, this one applies only to the decibel limits in 2701 (2704.1).

Leaf blowers. "Effective January 1, 2022, no person shall sell, offer for sale, or use a gasoline-powered leaf blower in the District of Columbia" (20 DCMR 2808.1(b)), and "A leaf blower shall not be used at nighttime, between the hours of 8:30 p.m. and 8:00 a.m." (2808.1(a)). A violation can bring "A civil fine not to exceed five hundred dollars ($500), penalties, and fees" (2808.6(b)). Any person may file a signed written complaint with the Mayor about gas-powered leaf blower use within one week of the use (2808.7). The leaf blower rules do not apply on federal lands and at federal facilities (2808.8).

Air conditioners and pool equipment. Noise from "any air-conditioning, refrigerator, heat pump, fan, swimming pool equipment, or other mechanical equipment, regardless of location," may not exceed 60 dB(A) measured at the property line (20 DCMR 2801.2).

Trash collection. "No person shall operate or permit the operation of any refuse collection vehicle in, or within three hundred (300) feet of, any residential, special purpose, or waterfront zone, at nighttime on any day of the week" (20 DCMR 2806.2).

Who enforces DC noise rules, and the penalties

The police enforce the noise regulations. "Any person who is aggrieved by a violation of any provision of the Act may complain to the Metropolitan Police Department which shall enforce the provisions of this Act" (20 DCMR 2713.1). Before issuing "a citation or notice of infraction," an officer or other District official "may give a verbal warning to the violator and allow the violator a reasonable time to cease violating the Act" (2713.2).

Officers may enforce the noise rules "by issuing a notice of civil infraction" (20 DCMR 2713.4), and "Civil fines, penalties, and fees may be imposed as alternative sanctions for any infraction of the provisions of Chapter 27 or 28" (2713.5). An infraction counts as a repeat when the same person violates the same provision within 3 years (16 DCMR 3201.2(a)). The base amounts in 3201.1 are adjusted each year for inflation under 3201.8, so the amount charged may differ from the figures shown.

Under 22-1321(h), a person who violates the disorderly conduct section "shall be guilty of a misdemeanor and, upon conviction, shall be fined not more than the amount set forth in 22-3571.01, imprisoned not more than 90 days, or both." Section 22-3571.01(b)(3) sets that fine at "$500 if the offense is punishable by imprisonment for 90 days, or 3 months, or less but more than 30 days."

Loud cars, car alarms and car stereos

Car stereos. Section 2800.1 covers stereo systems, "including those installed in motor vehicles," so loud music from a car can be a noise disturbance under 2800.2.

Altered exhausts. "No person shall use or operate a motor vehicle or a motorcycle having an exhaust system that has been modified or altered in a manner that will amplify or increase the noise emitted by the vehicle above the level permitted under" section 2811 (20 DCMR 2812.2), and 2812.1 bars making that kind of alteration.

Vehicle noise limits. Section 2811.1 sets these limits, measured 50 feet from the center line of travel:

Car alarms. It is unlawful to install, operate or use a vehicle theft alarm "that emits or causes the emission of an audible sound that is not, or does not become, automatically and completely silenced within five (5) minutes" (20 DCMR 2809.1).

Bars, restaurants and car horns

Licensed bars and restaurants. D.C. Code 25-725(a) provides that the holder of an on-premises retailer's license "shall not produce any sound, noise, or music of such intensity that it may be heard in any premises other than the licensed establishment" by an amplification device, a "Bell, horn, gong, whistle, drum, or other noise-making article, instrument, or device," or a "Musical instrument." Subsection (b) lists exceptions, including premises located within a commercial, manufacturing or mixed-use zone, areas of the building that are not part of the establishment, normal opening of entrance and exit doors, and heating, ventilation and air conditioning devices.

Horns. Under the traffic regulations, "No horn or other warning device shall emit an unreasonably loud or harsh sound or a whistle" (18 DCMR 730.2), and a driver "shall, when reasonably necessary to ensure safe operation, give audible warning with his or her horn, but shall not otherwise use the horn when upon a highway" (730.3).

Sound trucks. "Vehicle-mounted sound amplifying equipment, instruments, and transmitting devices shall be prohibited in streets or on highways after 9:00 p.m. and before 9:30 a.m." (20 DCMR 2807.3).

The 2025 amplified sound law (not yet funded)

D.C. Law 25-313, the Amplified Sound Mitigation Regulation Amendment Act of 2024, took effect on March 21, 2025. Among other things, it would require a license from the Department of Licensing and Consumer Protection to operate an amplified sound device in public space: "no person may occupy public space in the District while operating an amplified sound device without a valid license issued by the Department of Licensing and Consumer Protection" (sec. 103(a)).

The act carries a funding condition: "This act shall apply upon the date of inclusion of its fiscal effect in an approved budget and financial plan" (sec. 401(a)). The D.C. Code's entries for the sections the act created, including the public-space license sections at 10-1183.01 et seq. and 10-1185.01, are marked "Not Funded" and state that "that amendment has not been implemented."

The rules described elsewhere on this page are those in the current published DCMR text.

Loud neighbors: what you can do

For a noise problem next door in the District:

1. Call the police. The Metropolitan Police Department enforces the noise regulations on complaint (20 DCMR 2713.1), and an unreasonably loud noise from 10 p.m. to 7 a.m. that is likely to disturb people in their residences is a misdemeanor (22-1321(d)).
2. Know which standard applies. Music, amplifiers and voices are judged by the noise disturbance standard, which at night needs no decibel reading; other sources are measured against the zone limits in 2701.
3. Problem bars. Sound from a licensed establishment that can be heard in other premises falls under 25-725, subject to the exceptions in 25-725(b). The Alcoholic Beverage and Cannabis Administration must maintain a noise complaint program, staffed until at least one hour after alcohol sales end (25-725(d)(1)).

If you rent, see District of Columbia landlord-tenant laws for the landlord-tenant framework. Fireworks are covered in DC fireworks laws.

Frequently Asked Questions

What are the quiet hours in DC?

The District's noise regulations treat 9:00 p.m. to 7:00 a.m. as nighttime (20 DCMR 2799.1), when the residential limit drops to 55 dB(A). Disorderly conduct covers unreasonably loud noise from 10:00 p.m. to 7:00 a.m. that is likely to disturb people in their residences (D.C. Code 22-1321(d)).

What is the noise limit in a DC residential area?

In a residential, special purpose or waterfront zone, the limit is 60 dB(A) from 7 a.m. to 9 p.m. and 55 dB(A) from 9 p.m. to 7 a.m., measured at the property line of the property where the noise source is located (20 DCMR 2701).

What is the fine for a noise violation in DC?

A violation of the noise regulations is punishable by a fine of up to $1,000, up to 10 days in jail, or both, with each day a separate offense (20 DCMR 2713.3). Officers may instead issue a civil infraction: a noise disturbance from music or amplifiers is Class 2, with base fines of $1,000 for a first offense, $2,000 for a second, $4,000 for a third and $8,000 for a fourth or later, adjusted each year for inflation (16 DCMR 3201.1, 3201.8, 3310.2). Disorderly conduct for loud noise at night carries up to 90 days and a $500 fine (D.C. Code 22-1321(h), 22-3571.01).

Who do I call for a noise complaint in DC?

The Metropolitan Police Department enforces the District's noise regulations on complaint (20 DCMR 2713.1). An officer may give a verbal warning and a reasonable time to stop before issuing a citation or notice of infraction (2713.2).

What hours can construction happen in DC?

In residential, special purpose and waterfront zones, construction noise other than minor home repairs is not permitted on Sundays or legal holidays, or after 7 p.m. and before 7 a.m. on weekdays, which include Saturdays (20 DCMR 2803.2, 2799.1). On weekdays from 7 a.m. to 7 p.m., construction noise is capped at 80 dB(A) Leq(1) (2802.1).

Does DC need a decibel reading to cite loud music?

A noise disturbance from music, amplifiers or voices is judged by whether it unreasonably disturbs a reasonable person, and if the noise is made at night or does not involve noncommercial public speaking, the District is not required to measure decibels (20 DCMR 2799.1, 2800.2).

Is the DC amplified sound law in effect?

D.C. Law 25-313 took effect March 21, 2025, but it applies only once its fiscal effect is included in an approved budget (sec. 401(a)), and the D.C. Code marks the sections it created, including 10-1183.01 et seq. and 10-1185.01, as Not Funded and not implemented.
