Quiet hours in Phoenix, AZ — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Phoenix does not set decibel-keyed citywide quiet hours, but City Code section 23-14 specifically targets the playing of radios, phonographs, and musical instruments between 11:00 p.m. and 7:00 a.m. when the sound disturbs persons nearby, and the general nuisance-noise prohibition in section 23-12 applies at any hour.
Phoenix regulates nighttime noise through a nuisance standard rather than fixed numeric limits. Phoenix City Code section 23-12 (Chapter 23, Article I, Division 2 - Nuisances and Noise) makes the 'creating of any unreasonably loud, disturbing and unnecessary noise within the limits of the City' unlawful, and section 23-13 prohibits noise 'of such character, intensity or duration as to be detrimental to the life or health of any individual or in disturbance of the public peace and welfare.' The closest thing to a fixed quiet-hours window is section 23-14(b), which singles out 'the playing of any radio, phonograph or any other musical instrument' in a manner or volume 'particularly between the hours of 11:00 P.M. and 7:00 A.M.' that annoys or disturbs the quiet, comfort or repose of persons in any office, hospital, dwelling, hotel or other residence. Separately, the city's Loud Party / Event ordinance (City Code section 2-22, adopted by Ordinance G-6674) attaches escalating police-response fees to any gathering of five or more persons that becomes 'a threat to the peace, health, safety and general welfare of the public,' with no 'allowable' time of day or night. Routine nighttime disturbances are handled by the Phoenix Police Department non-emergency line at 602-262-6151.
Loud-party/event response fees under section 2-22 are capped at $1,000 (first incident in a 12-month period), $1,500 (second), and $2,000 (third and subsequent). The fee is waived if a responsible party requested the police response and assists in dispersing the gathering. Chapter 23 nuisance-noise violations are charged separately as misdemeanors.
