Where to file in Baltimore
Baltimore City 311: dial 3-1-1 (443-263-2220 from outside the city), the Baltimore 311 app, or the online service request system, seven days a week 6:00 a.m. to 10:00 p.m.; noise nuisances are investigated by the Health Department's Environmental Health division and enforced by notice from the Commissioner of Health, with environmental or civil citations (baltimorecity.gov, "311 Services" and "Nuisance Complaint Investigations"; Health Code §§ 9-212, 9-217). Loud parties in progress are a police matter through 311.
From the city's official pages and code, verified 2026-09-03. Numbers and departments change; if a line does not answer, the city's main switchboard or 311 can redirect you.
Before you call
- 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.
- Measure it if you can. Baltimore sets measured limits, so a reading near the limit is direct evidence. The free online decibel meter runs in your browser and records nothing.
- Check the rule. Quiet hours in Baltimore are 9:00 p.m. – 7:00 a.m.: limits drop 5 dB(A) (§ 9-207); power tools only 7 a.m. – 9 p.m. weekdays. The Baltimore noise ordinance page quotes the code verbatim, so you can cite the section.
- 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.

Should I call 911 for noise in Baltimore?
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 Baltimore?
Baltimore 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.
