The Short Version

Denver runs one of the stricter noise ordinances among major Western cities. Quiet hours are 7 PM to 7 AM in residential areas — earlier than most places. During those hours, the limit is 50 dB at your property line. Daytime maxes out at 55 dB for residential, which is quieter than a normal conversation. The city uses actual decibel meters for enforcement, not just the "I can hear it" standard. Denver's Environmental Health division handles complaints, not the police, which means they take a more methodical approach but enforcement can be slower.

Full Breakdown

Denver's noise ordinance (DRMC Section 36-3) is measured-based, meaning the city doesn't just ask whether the noise is "unreasonable" — they'll actually show up with a sound meter. Residential zones cap at 55 dB during the day (7 AM to 7 PM) and 50 dB at night. For reference, 55 dB is roughly the level of a quiet office, so this is a tight standard.

The 7 PM start time catches people off guard. In most cities, quiet hours don't kick in until 10 PM. In Denver, your backyard party needs to wind down well before dark in the summer months. Music, amplified sound, and persistent noise sources are the main targets.

Complaints go through the Department of Public Health & Environment's Environmental Quality division, not through police dispatch. This means you call 311, not 911. Investigators may schedule a follow-up visit rather than responding immediately, which frustrates some residents but leads to more documented enforcement actions.

What Happens If You Violate This?

First offense carries a fine between $100 and $999. Each subsequent violation within a year increases the minimum fine. Chronic offenders can be charged with a misdemeanor. The city also has authority to seize noise-making equipment in extreme cases.

Frequently Asked Questions

Why are Denver's quiet hours so early?
Denver's 7 PM cutoff dates back to ordinance revisions in the 1990s and reflects the city's low ambient noise levels in residential areas. There have been proposals to push it to 9 PM but none have passed council yet.
Can I mow my lawn after 7 PM in Denver?
Technically a gas mower puts out about 90 dB, which is well over the 50 dB nighttime limit. Push reel mowers or quiet electric mowers might stay under the threshold, but you're safer sticking to daytime hours.
Does Denver enforce noise rules for barking dogs?
Yes. Barking dogs fall under the noise ordinance and also under Denver Animal Protection's rules. Persistent barking — generally defined as 20+ minutes — can result in citations for the dog owner.
