Official text: District of Columbia Municipal Regulations (DCMR), Title 20 (Environment), Chapter 27 "Noise Control" (https://dcregs.dc.gov/Common/DCMR/RuleList.aspx?ChapterNum=20-27) and Chapter 28 "Maximum Noise Levels" (https://dcregs.dc.gov/Common/DCMR/RuleList.aspx?ChapterNum=20-28), issued under the District of Columbia Noise Control Act of 1977 (D.C. Law 2-53). Chapter 27: § 2700 general provisions; § 2701 maximum sound levels (the zone-by-zone dB(A) table, measurement at the property line, contiguous-zone rule, 60 dB(A) default, motor-vehicle interior measured at 50 ft); §§ 2702-2704 exemptions (pre-existing sources, rail vehicles/WMATA, construction equipment, emergency signals and vehicles, and the § 2704.6 home power-tool exemption); §§ 2705-2707 variances and temporary exemptions; §§ 2710-2714 notices of violation, emergency procedures, penalties and civil enforcement; § 2799 definitions ("Daytime," "Nighttime," "Weekday," "Noise disturbance," "Leg," and the three noise zones).

Where to file in Washington

There is no single noise line - DC splits noise complaints by source, and the Department of Buildings publishes the routing. Construction outside legal hours or without an after-hours permit goes to the Department of Buildings, (202) 671-3500 or dob@dc.gov, via its online request-for-inspection form. Noise from a bar, restaurant, nightclub or cannabis establishment goes to the Alcoholic Beverage and Cannabis Administration (ABCA) on (202) 442-4423 or through its online complaint form; D.C. Official Code § 25-725(d) requires ABCA to keep a phone, email and fax complaint channel operating until at least one hour after the legal end of alcohol sales, and ABCA's Noise Task Force conducts checks several times a week. Trash-truck noise goes to the Department of Licensing and Consumer Protection (DLCP). All other noise in public space goes to the Metropolitan Police Department - for a non-emergency, call the District's 311 line; call 911 only in an emergency. Note that the 311 system does not yet have dedicated noise-complaint categories with automatic routing: that was ordered by D.C. Law 25-313, which is unfunded and not implemented, so residents should expect to identify the right agency themselves.

From the city's official pages and code, verified 2026-08-11. Numbers and departments change; if a line does not answer, the city's main switchboard or 311 can redirect you.

Before you call

1. Log it. Date, start and end time, what the noise was and where you heard it from. Three dated entries carry more weight than one angry call.
2. Measure it if you can. Washington sets measured limits, so a reading near the limit is direct evidence. The free online decibel meter runs in your browser and records nothing.
3. Check the rule. Quiet hours in Washington are 9:00 p.m. – 7:00 a.m. (10:00 p.m. criminal offence). The Washington noise ordinance page quotes the code verbatim, so you can cite the section.
4. Try the source once. A neighbour, landlord or venue manager often fixes it faster than the city does, and telling them first strengthens a later complaint.

What happens after you file

Non-emergency noise reports are queued, not dispatched, so a first call rarely ends the noise that night. What it does is start a record against the address. Repeated reports, a dated log and a reading are what move a case from a warning to a citation. Where the city needs an officer to witness the noise, as most audibility rules require, file while it is happening rather than the next morning.

Who do I call for a noise complaint in Washington?

There is no single noise line - DC splits noise complaints by source, and the Department of Buildings publishes the routing.

9:00 p.m. – 7:00 a.m. (10:00 p.m. criminal offence). The full rule, quoted from the code, is on the Washington noise ordinance page.

Should I call 911 for noise in Washington?

Only if there is danger, a threat or a crime in progress. For ongoing noise use 311 or the non-emergency police line; repeated calls build an official record tied to the address, which is what code enforcement acts on.

What evidence helps a noise complaint in Washington?

Washington uses both decibel limits and audibility rules, so keep a dated log and take readings when you can; which rule applies depends on the source of the noise.
