Arizona noise disturbance laws work on two levels. The state’s disorderly conduct statute makes unreasonable noise a Class 1 misdemeanor when someone intends to disturb the peace or knows their noise is doing so, carrying up to six months in jail and a $2,500 fine. Everything else — decibel limits, quiet hours, party response fees, construction windows — comes from city and county ordinances, which vary considerably across Phoenix, Tucson, Scottsdale, and Flagstaff.
The State Disorderly Conduct Statute
ARS 13-2904 is the main state-level tool. A person commits disorderly conduct by making unreasonable noise with the intent to disturb the peace of a neighborhood, family, or person, or with knowledge that the noise is doing so.1Arizona Legislature. Arizona Revised Statutes Title 13-2904 – Disorderly Conduct; Classification The statute does not set a decibel number. Officers judge the situation by volume, duration, time of day, and whether the noise is out of character for the location.
The mental-state requirement matters. Prosecutors need to show you either intended to disturb someone or knew you were. Making noise incidentally during a legitimate daytime activity typically will not qualify. Blasting music at 2 a.m. after neighbors have complained will.
One narrower state rule sits alongside the disorderly conduct statute. ARS 28-955.01 requires every motorcycle to have its original manufacturer’s muffler or a replacement that keeps noise below federal EPA maximums, and it bans cutouts, bypasses, and similar modifications.2Arizona Legislature. Arizona Revised Statutes Title 28-955.01 – Motorcycles; Noise Level Equipment; Unauthorized Equipment This applies whether or not the rider meant to bother anyone.
Penalties for a Noise-Related Disorderly Conduct Charge
A noise-based violation of ARS 13-2904 is a Class 1 misdemeanor, Arizona’s most serious misdemeanor class.1Arizona Legislature. Arizona Revised Statutes Title 13-2904 – Disorderly Conduct; Classification The maximum exposure includes up to six months in jail,3Arizona Legislature. Arizona Revised Statutes Title 13-707 – Misdemeanors; Sentencing a fine of up to $2,500,4Arizona Legislature. Arizona Revised Statutes Title 13-802 – Fines for Misdemeanors and up to three years of probation.5Arizona Legislature. Arizona Revised Statutes Title 13-902 – Periods of Probation; Monitoring; Fees
A first-time noise complaint that leads to a disorderly conduct charge rarely produces jail time. Courts more commonly impose fines, probation, or community service. Repeat offenders and those who refuse to comply after warnings face harsher treatment. A conviction also stays on your criminal record and can affect employment and housing applications.
City Noise Ordinances
Most day-to-day noise regulation happens locally. Cities set decibel limits, designate quiet hours, and regulate specific sources like construction and amplified music. Violating a city ordinance can trigger a separate civil citation even when police do not pursue criminal charges.
Phoenix
Phoenix designates 10 p.m. to 7 a.m. as quiet hours and has a separate loud party ordinance that bills the responsible person for police response. Response costs are capped at $1,000 for the first incident within a 12-month period, $1,500 for the second, and $2,000 for the third and any after.6City of Phoenix. Loud Party Ordinance The city waives those costs if you call police yourself and help disperse the crowd before things escalate.
Tucson
Tucson sets limits by time of day in residential zones: 70 decibels from 7 a.m. to 10 p.m., and 62 decibels from 10 p.m. to 7 a.m. Complaints go in by phone or through the online Tucson 311 portal.7City of Tucson. Report a Concern
Scottsdale
Scottsdale uses a subjective standard instead of a decibel meter. Noise is unreasonable if a reasonable person would find it excessive and it can be heard at least 100 feet from the source.8City of Scottsdale. Frequently Asked Questions – Special Noise Ordinance Officers can cite based on their own judgment. Scottsdale police also have authority to determine whether sound from entertainment districts rises to disorderly conduct under state law.
Flagstaff
Flagstaff’s ordinance carves out exemptions for public safety work, meaning emergency repairs, property restoration after damage, and utility service restoration. Nighttime government construction on public property is also exempt when public welfare requires it.9City of Flagstaff Municipal Code. Chapter 6-08 Noise Control
If You Rent or Your Neighbor Does
The Arizona Residential Landlord and Tenant Act requires tenants to behave in a way that does not disturb neighbors’ peaceful enjoyment of the premises.10Arizona Department of Housing. Arizona Residential Landlord and Tenant Act – Section 33-1341 Breach of that duty gives the landlord grounds to start eviction.
The notice window depends on the severity. For a general lease violation like repeated noise complaints, the landlord must deliver a written notice describing the problem and giving the tenant at least 10 days to fix it. Where the noise affects health and safety, the notice drops to five days. Resolving the issue within the notice period keeps the lease alive.11Arizona Department of Housing. Arizona Residential Landlord and Tenant Act – Section 33-1368 If the same problem happens again during the lease term, the landlord can pursue eviction 10 days after a second written notice, with no further chance to cure.
If you are the one being disturbed by another tenant, document the disturbances and notify your landlord in writing. When the landlord fails to act, that failure can undermine your right to peaceful use of your home, and remedies range from requesting a rent reduction to seeking damages in justice court.
HOA Fines for Noise
Many Arizona residents also answer to HOA rules that go further than city ordinances, often restricting noise during set hours, limiting construction, and addressing barking dogs or amplified music. State law lets HOA boards impose reasonable monetary penalties for violations of the declaration, bylaws, and rules, but only after notice and an opportunity to be heard.12Arizona Legislature. Arizona Revised Statutes Title 33-1803 – Assessment Limitation; Penalties; Notice to Member of Violation
If you receive a violation notice, you have 21 days to respond in writing by certified mail. The association then has 10 business days to identify the specific provision you allegedly violated, the date, who observed it, and how to contest it.12Arizona Legislature. Arizona Revised Statutes Title 33-1803 – Assessment Limitation; Penalties; Notice to Member of Violation The HOA cannot pursue enforcement, including collecting attorney fees, until that exchange is complete. Depending on the dispute, you may also petition for an administrative hearing through the Arizona Department of Real Estate.
How to Report a Noise Disturbance
For an ongoing disturbance like a loud party, persistent barking, or late-night amplified music, call the local police non-emergency line. Officers respond, assess, and either warn, cite, or take no action based on what they observe. Scottsdale’s process is typical: dispatch gathers information, prioritizes the call, and sends the beat officer to verify.8City of Scottsdale. Frequently Asked Questions – Special Noise Ordinance
For recurring or non-emergency issues like a neighbor’s air conditioning unit or a business operating outside permitted hours, code enforcement is usually the right contact. Many cities take complaints online; Tucson’s 311 system accepts submissions through the web.7City of Tucson. Report a Concern
Documentation makes the difference. Record the date, time, duration, and nature of each disturbance. Audio or video captured from your own property strengthens the case. For patterns, keep a written log. Complaints from multiple households about the same source carry more weight with both police and code enforcement.
Suing Over Ongoing Noise
When criminal enforcement and code complaints fail, a private nuisance suit is the next step. You need to show that someone’s actions substantially and unreasonably interfere with your use and enjoyment of your property. Persistent loud noise is one of the most common examples.
Courts generally look at four things: whether you have a legal right to use the property as an owner or tenant, whether the noise crosses onto your property, whether the interference is substantial rather than trivial, and whether a reasonable person in your position would find the noise excessive. Judges also weigh the character of the neighborhood, whether the noise source predated you, and the social value of the activity.
Remedies go beyond what criminal enforcement offers. A judge can issue an injunction ordering the neighbor or business to stop the activity, reduce it, or limit it to certain hours. Money damages for diminished use of your property are also available. Smaller disputes go to Arizona’s justice courts,13Arizona Judicial Branch. Justice Court Filing Fees while larger claims or requests for injunctive relief usually belong in superior court.
Defenses If You Are the One Cited
The strongest defense is usually proving compliance with the applicable limit. Where the city uses decibel thresholds, an independent sound measurement showing you were within range can end the case. Where the standard is subjective, like Scottsdale’s reasonable-person test, the argument shifts to context: sound that would be unreasonable in a quiet cul-de-sac may be normal near an entertainment district.
Exemptions matter too. Flagstaff exempts emergency repairs and certain government construction.9City of Flagstaff Municipal Code. Chapter 6-08 Noise Control Many cities allow construction within designated daytime hours, and permitted entertainment venues often have higher allowances. If your activity fits a recognized exemption, the ordinance simply does not apply.
For a disorderly conduct charge under ARS 13-2904, the prosecution must prove you intended to disturb someone or knew you were doing so.1Arizona Legislature. Arizona Revised Statutes Title 13-2904 – Disorderly Conduct; Classification Where the noise was incidental to a legitimate activity and you had no reason to know it was disturbing anyone, that mental-state requirement is a meaningful defense. Activities protected by the First Amendment, including political demonstrations and religious gatherings, receive heightened protection, though they remain subject to reasonable time, place, and manner restrictions.
