Flagstaff, AZ Short-Term Rentals: Noise Rules (2026)

Chapter 3-12 does not set a separate decibel or curfew standard for STRs; instead § 3-12-001-0007(A)(3) folds the City's general noise ordinance into STR licensing by declaring any STR use that violates 'noise regulations' a prohibited use. That ties directly to Flagstaff City Code § 6-08-001-0002 (Nuisance Noise), which sets the hours the standard applies: Monday through Friday from midnight to 6:00 a.m., and Saturday and Sunday from 1:00 a.m. to 7:00 a.m. During those windows, it is unlawful for any person, indoors or outdoors, to make or permit noise that is clearly audible inside a residential unit other than the one where the noise originated. Whether a sound rises to a violation turns on its volume, whether it is usual or unusual for the area, the level of background noise, and how long it lasts, per § 6-08-001-0002(C).

Because an STR noise complaint is charged as a violation of the STR chapter's prohibited-use provision, it exposes the owner to STR-specific enforcement rather than only a municipal noise citation: the owner or emergency point of contact must be reachable within sixty minutes of a police request tied to an emergency, and a verified noise violation counts toward the escalating civil penalties of § 3-12-001-0015 ($500, then $1,000, then $3,500) and toward the three-violation threshold that can support a license suspension of up to twelve months under § 3-12-001-0014. Advertisements or listings referencing the property can serve as prima facie evidence of a prohibited use where the STR is marketed for the kind of gathering that generates the noise.
