How to File a Noise Complaint
To file a noise complaint, document the problem first — log the date, time, how long it lasted and roughly how loud — then work up an escalation ladder: talk to the source, tell your landlord or HOA, and call your city 311 line or non-emergency police for ongoing noise (not 911). Quiet hours and limits vary by city, so check your local ordinance.

How to file a noise complaint (step by step)
- Document the noise. Log the date, time, how long it lasted, roughly how loud it was, and what it was. A pattern of entries is the evidence; any single reading is weak.
- Talk to the source first. Tell the neighbor or business once, politely. A surprising share of cases end here, and a record that you tried matters later.
- Check your local quiet hours and ordinance. Search your city code for "noise" to see the limits and overnight quiet hours that apply where you live.
- Report it to 311 or non-emergency police. Use your city 311 line or the non-emergency police number for ongoing noise. Reserve 911 for emergencies.
- Escalate if it continues. Bring your log to code enforcement, your landlord or HOA, or mediation. Repeated, dated entries are what move each step.

Who do you call for a noise complaint? (311 vs police vs 911)
This is the part people get wrong. For ordinary noise — music, parties, barking, construction — use your city's 311 line or the non-emergency police number, not 911. 911 is for emergencies: danger, a threat, or a crime in progress. Work up the ladder, because each rung is cheaper than the next:
| Who to contact | When to use it |
|---|---|
| The neighbor or source | First, once, politely — many cases end here, and it shows you tried. |
| Landlord, building manager or HOA | For rentals and HOAs — "quiet enjoyment" clauses and house rules are often the fastest lever. |
| City 311 or the non-emergency police line | Ongoing or repeated noise. Calls create an official record tied to the address. |
| Code enforcement / environmental health | Persistent problems — this is who shows up with a calibrated meter during the noise. |
| 911 | Only if there is danger, a threat or a crime in progress — not for routine noise. |
What are "quiet hours"?
Many cities set overnight quiet hours — often somewhere around 10 or 11 pm to 7 am — when noise limits tighten. But the exact hours, the decibel limits, and whether the rule is decibel-based or a "plainly audible at the property line" nuisance standard all vary by city. Search your city's municipal code for "noise" before assuming a number — a reading that seems damning may be within the rules, and vice versa. For context, the WHO recommends keeping night-time outdoor noise below 45 dB Lnight to protect sleep; see noise pollution for the health side.
How do you prove a noise complaint?
With a pattern, not a single number. An uncalibrated phone or browser reading rarely stands as certified proof of a specific decibel violation — code enforcement and courts use their own calibrated meters. But a consistent log (same spot, same way, every time) of dates, times, durations and levels, alongside a quiet-night baseline, is exactly what convinces a landlord to act, a mediator to take you seriously, or an officer to schedule a visit during the noise. One caveat: logging noise levels is fine everywhere, but recording your neighbor's conversations may break wiretapping laws that vary by state — record the thump, not the words.
Complaints about a business, bar or construction
The route is similar, but the regulator is usually code enforcement or the local environmental health department rather than the police, and commercial sources are often held to specific permit conditions and hours. Document it the same way, and check whether the business has a noise or construction permit you can reference. To see how loud your area runs overall, the US city noise map ranks every US city of 100,000+ residents from federal data.
This is general documentation guidance, not legal advice; noise rules differ by city, state and country. Always check your local ordinance for the limits and procedures that apply to you.
Common questions
How do I file a noise complaint?
Document the noise first — date, time, how long it lasted and roughly how loud — then work up an escalation ladder: talk to the source, tell your landlord or HOA, and call your city 311 line or non-emergency police for ongoing noise. Bring your log if it reaches code enforcement.
Who do I call for a noise complaint?
For routine noise, call your city 311 line or the non-emergency police number, or your landlord, building manager or HOA. Call 911 only if there is danger, a threat or a crime in progress. Repeated calls to the non-emergency line build an official record tied to the address.
What are quiet hours?
Many cities set overnight "quiet hours" — often somewhere around 10 or 11 pm to 7 am — when noise limits tighten. But the exact hours, the decibel limits, and whether the rule is decibel-based or a "plainly audible" nuisance standard all vary by city, so check your local municipal code.
Will a phone decibel reading work as evidence?
Rarely as certified proof of a specific violation — phone and browser meters are not calibrated, so code enforcement and courts use their own meters. What a reading does well is establish a pattern: a consistent log of dates, times and levels is what convinces a landlord, mediator or officer to act.
