Denver Noise Complaints Map 2025–2026

Denver noise complaint filings have reached a 4-year high. The city received 1,640 noise-related 311 calls in the 12 months ending April 2026 — up 28% from 2023 (1,280 complaints) and 42% above 2021 levels (1,155 complaints). The 2021→2022 period saw a +14% swing as Denver's post-pandemic nightlife recovery accelerated, while 2022→2023 saw a slight 3% dip as enforcement activity increased. The current 12-month figure suggests Denver's growing entertainment district density — driven by new bar openings in RiNo, Baker, and South Broadway — is generating sustained resident friction.

Note: Denver did not publish a 2024 annual 311 dataset. The current figure covers February 2025 through April 2026 from the live ODC rolling endpoint.

911 NOISE COMPLAINT is Denver's most-reported noise category, accounting for 42% of all 311 noise filings. The 911 NOISE COMPLAINT category — representing cases escalated to Denver Police dispatch — has emerged as the largest single type, reflecting how seriously residents treat severe disturbances. Bar noise, amplified music, and nightlife-related calls collectively represent 55% of complaints, concentrated in entertainment districts. Construction noise (11%) spikes during permit-heavy development periods, particularly in rapidly densifying neighborhoods like LoHi, RiNo, and the Platte River corridor.

LoDo leads all Denver neighborhoods with 97 noise complaints in the current 12-month period, representing 6% of all filings citywide. RiNo (75) and Capitol Hill (55) round out the top three. These rankings track the density of late-night entertainment relative to residential population — neighborhoods with many bars and music venues per residential block consistently generate the highest complaint volumes. The heat map above lets you explore exact complaint clusters within each neighborhood.

August 2025 is Denver's noisiest month, logging 159 noise complaints. Summer months (June–August) average 145 complaints per month — 31% more than the winter average of 111/month in December–February. Denver's outdoor bar culture, rooftop venues, RiNo outdoor concerts, and Coors Field events create a pronounced warm-weather surge. Red Rocks Amphitheatre season (May–October) also generates noise complaints along the Morrison Road corridor. Conversely, winter months see a noticeable drop — though bars and clubs remain active, fewer outdoor events and shorter days limit the peak-hour window for complaints.
