Summary

In unincorporated Pima County, the noise code bans excessive, unnecessary or offensive sound that disturbs a neighborhood or annoys a reasonable person of normal sensitivity, rather than setting a single decibel meter reading. Specific numeric limits apply to radios (125 feet), night hours and construction. Violations are a class 1 misdemeanor.

City-specific rules exist: Tucson, and Sahuarita have their own decibel limits rules that differ from Pima County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

9.30.040 Impermissible sound levels. In addition to the prohibited noises described in 9.30.050, 9.30.060 and 9.30.070, it shall be unlawful for any person to make or continue, or cause or permit to be made or continued, any excessive, unnecessary or offensive noise which disturbs the peace or quiet of any neighborhood or which causes discomfort or annoyance to any reasonable person of normal sensitivity residing in the area.

Full Breakdown

070. , a rule that applies equally to restaurants, bars, inns and resorts. , requires a functioning, unmodified muffler, and bans tire-squealing. m. m. start.

This chapter applies only inside unincorporated Pima County; it does not reach Tucson, Marana, Oro Valley, Sahuarita or South Tucson, each of which enforces its own noise code.

Violations & Fines

Violating any part of Chapter 9.30, whether the general nuisance standard, the 125-foot radio rule, the nighttime vehicle-repair ban or unpermitted construction hours, is declared a public nuisance and a class 1 misdemeanor, Arizona's top misdemeanor tier (up to six months jail and a $2,500 fine). Each day a violation continues counts as a separate offense, so unresolved construction or party noise can generate a new charge daily until it stops.

Frequently Asked Questions

Does Pima County set a decibel limit for noise complaints?
No fixed decibel meter reading. Section 9.30.040 instead bans any excessive, unnecessary or offensive noise that disturbs a neighborhood's peace or annoys a reasonable person of normal sensitivity, backed by the specific radio, vehicle and construction rules in the same chapter.
How loud can I play music at home in unincorporated Pima County?
Section 9.30.050 makes it unlawful to run a radio, stereo or musical instrument so it's audible more than 125 feet from your property line at any time, and unlawful for it to be audible beyond your property line at all between 10:00 p.m. and 7:00 a.m.
What construction hours does Pima County allow near homes?
In residential zones, work is limited to 6:00 a.m.-7:00 p.m. from April 15 to October 15 and 7:00 a.m.-7:00 p.m. the rest of the year, per Section 9.30.070. Weekends and holidays are restricted to 7:00 a.m.-7:00 p.m., though a county permit can authorize different hours.
What happens if I'm cited for a noise violation?
Section 9.30.090 makes any Chapter 9.30 violation a class 1 misdemeanor and a declared public nuisance. Each day the noise continues is charged as a new, separate offense, so an unresolved problem can rack up multiple counts.
Does this noise code apply inside Tucson?
No. Section 9.30.010 limits Chapter 9.30 to unincorporated Pima County. Tucson, Marana, Oro Valley, Sahuarita and South Tucson each enforce their own municipal noise ordinance instead.
