Summary

Amplified music falls under the county nuisance ordinance in unincorporated areas and city codes elsewhere. Flagstaff's downtown entertainment district and NAU party scene make late-night amplified sound a recurring, closely watched issue.

These county ordinances apply to unincorporated areas of Coconino County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Full Breakdown

In the unincorporated county, amplified music is governed by the general nuisance rules and A.R.S. §13-2904 disorderly conduct, enforced by the Sheriff's Office. Flagstaff is the flashpoint: its Chapter 6-08 ordinance bars noise clearly audible inside another home overnight and lets officers cite each person contributing to a disturbance at a gathering of five or more. Downtown bars and patios versus nearby residents drove a contested 2024 ordinance review and an acoustic study, with the City Council narrowly rejecting a proposed change. Outdoor public events need city permits with noise conditions.

Violations & Fines

Unincorporated amplified-noise is cited under the county nuisance ordinance or A.R.S. §13-2904 disorderly conduct, a class 1 misdemeanor up to $2,500. Flagstaff issues civil citations to each contributor at a party disturbance; unpermitted public events draw added fines.
