What's specific to Denver
- Denver was actively revising Chapter 36 during 2026, including the exemption level for permitted events and limits on private-property events — check the current text before relying on any figure here.
- Administrative citations can reach $5,000 per day, among the steepest of the metros covered here.
What Denver residents most often report
- Construction outside permitted hours, judged by audibility rather than level.
- Permitted outdoor events, where the exemption level itself was under revision during 2026.
- Vehicle noise in public places, capped separately at 75 dB.
How to measure it in Denver
Measure at the property line and compare against 55 dB daytime or 50 dB at night, remembering that weekend quiet hours start an hour later and run an hour longer. For construction there is a separate and simpler test: plainly audible construction noise is prohibited 9:00 PM – 7:00 AM on weekdays and 5:00 PM – 8:00 AM at weekends.
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.
