Sacramento noise rules at a glance
- Governing code: Sacramento City Code, Chapter 8.68 (Noise Control)
- Quiet hours: 10:00 PM – 7:00 AM, when the exterior standard drops to 50 dBA
- How violations are judged: Measured decibel limits
- Complaints: 311
How Sacramento decides what counts as too loud
Sacramento grades its limit by how long the noise lasts within each hour, so a brief loud event and a constant one are judged against different numbers rather than the same cap.
Noise limits in Sacramento
| Applies to | Daytime | Night |
|---|---|---|
| Residential and agricultural exterior standard | 55 dBA, 7:00 AM – 10:00 PM | 50 dBA, 10:00 PM – 7:00 AM |
| Duration allowance within any one hour | +0 dB for 30 cumulative minutes, +5 for 15 minutes, +10 for 5 minutes, +15 for 1 minute, +20 never to be exceeded | Same graded allowance, applied to the lower night standard |
| Impulsive or tonal noise, speech and music | Each limit reduced by 5 dBA | Each limit reduced by 5 dBA |
What's specific to Sacramento
- Because the allowance is cumulative per hour, the useful evidence is total minutes above a level, not a single peak.
- Music and speech are explicitly docked 5 dBA, so a neighbour's stereo is judged more strictly than a machine at the same reading.
- If the ambient level already exceeds a category, the allowable limit rises in 5 dBA steps to meet it, so a genuinely noisy street does not create automatic violations.
What Sacramento residents most often report
- Amplified music and speech, which the code judges 5 dBA more strictly than other sources.
- Intermittent commercial activity — deliveries, compressors cycling — where the duration grading decides the outcome.
- Late-evening equipment running past the 10:00 PM drop to the 50 dBA standard.
How to measure it in Sacramento
Record for a full hour and keep the timeline. Sacramento's standard is written as minutes-per-hour above a level — 30 minutes at 55 dBA, 5 minutes at 65, one minute at 70 — so the number that decides a complaint is a duration, not a peak. A session log showing how many minutes the noise spent above each threshold maps directly onto the table; a screenshot of a maximum reading does not.
Record levels with the free online decibel meter, and log the date, start time and duration with each reading. A phone microphone is accurate to roughly ±2 dB and is not a calibrated instrument — enough to establish a pattern, not enough for an enforcement hearing.
Turn your readings into something you can file
311 will ask when the noise happens and how long it lasts. A live decibel reading answers neither. Pro records a timestamped session — a ten-minute check or a full night — charts the whole thing, and exports a PDF with the dates, times, duration and the statistics that describe a pattern rather than a moment.

How to file a noise complaint in Sacramento
Ongoing sources go to code enforcement through 311; parties and immediate disturbances go to the police non-emergency line.
