Mesa's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Mesa, Arizona, there are 6 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Vehicle Noise

Mesa bans unreasonable vehicle noise from grinding, exhaust, or engine sounds, and separately makes a car stereo illegal if it's plainly audible 50 feet away. Both are civil offenses that escalate quickly with repeat findings.

Key details: Stereo audibility standard: Plainly audible at 50 feet. Covered mechanical sources: Grating, grinding, rattling, exhaust, engine. First civil sanction: $250-$1,500. Enforcing agencies: Police and Code Compliance Officers. Habitual offender penalty: Up to 6 months jail, $500-$2,500 fine.

A first civil finding for vehicle or stereo noise costs $250-$1,500, rising to $500-$2,500 on a second finding within 24 months and $750-$2,500 on a third. Three findings within 12 months trigger habitual-offender status under § 6-12-11: a class 1 misdemeanor, up to six months in jail, and a minimum $500 fine per count.

Aircraft Noise

Mesa requires a Police Chief permit before any helicopter takes off or lands anywhere in the city outside an established heliport, and the Chief may deny it if the noise would be detrimental to the neighborhood. News, accident-response, and police-assistance flights are permit-exempt; pesticide flights need owner consent and a 500-foot residence buffer.

Key details: Governing section: Mesa City Code § 6-3-6. Permit authority: Chief of Police or designee. Noise condition: Must not be detrimental to neighborhood. Insurance minimum: $100k/person, $300k/occurrence. Pesticide-flight buffer: 500 ft from a residence.

Taking off or landing a helicopter without a required Police Chief permit, or otherwise violating Chapter 3, is a misdemeanor under § 6-3-7: a fine up to $2,500, imprisonment up to three months, or both.

This is not one of those rules that cities tend to ignore. Mesa actively enforces its aircraft noise requirements.

Barking Dogs

Mesa bars owning or keeping any animal that makes frequent or long, continued sound disturbing a neighbor's peace. There's no fixed minutes-of-barking trigger; Animal Control and Code Compliance decide case by case, and repeat findings escalate fast.

Key details: Governing section: Mesa City Code § 6-12-4. Standard: Frequent or long, continued sound disturbing a reasonable person. First civil sanction: $250-$1,500. Presumed responsible party: Owner, manager, or occupant of the property. Habitual offender trigger: 3 findings within 12 months.

A first civil finding for animal noise costs $250-$1,500, doubling to $500-$2,500 on a second finding within 24 months and $750-$2,500 on a third. Three findings within 12 months make the owner a habitual offender facing a class 1 misdemeanor, up to six months in jail, and a mandatory minimum $500 fine per count.

Quiet Hours

Mesa's general noise ordinance treats sound occurring between 10:00 p.m. and 6:00 a.m. as an aggravating factor when deciding whether it violates the code. There's no blanket decibel curfew, but nighttime timing weighs heavily against a noisemaker facing a citation.

Key details: Nighttime window: 10:00 p.m. to 6:00 a.m.. First civil sanction: $250-$1,500. Habitual-offender jail exposure: up to 6 months. Enforcing agencies: Police, Code Compliance, Animal Control, Park Rangers. Governing chapter enacted: Ord. No. 5750, Dec. 1, 2022.

A first civil finding runs $250-$1,500, a second within 24 months $500-$2,500, and a third within 24 months $750-$2,500, with every incident charged separately. Anyone found responsible three times within 12 months becomes a habitual offender facing a class 1 misdemeanor, up to six months in jail, and a fine of at least $500 per count up to $2,500.

Construction Hours

Mesa exempts construction, demolition, and excavation noise from its nuisance ordinance only between 6:00 a.m. and 8:00 p.m. weekdays, with a narrower Saturday-Sunday window limited to the resident's own home. Outside those hours it's a Chapter 12 violation.

Key details: Weekday exempt hours: 6:00 a.m.-8:00 p.m., Mon-Fri. Weekend exempt hours: 6:00 a.m.-8:00 p.m., own residence only. Golf course/private park landscaping: 5:00 a.m.-8:00 p.m., all 7 days. First civil sanction outside hours: $250-$1,500. Governing chapter enacted: Ord. No. 5750, Dec. 1, 2022.

Construction noise outside the permitted windows is a civil violation of § 6-12-3, carrying $250-$1,500 for a first finding, $500-$2,500 for a second within 24 months, and $750-$2,500 for a third. Three findings within 12 months make the responsible contractor or resident a habitual offender under § 6-12-11, facing a class 1 misdemeanor and up to six months in jail.

Decibel Limits

Mesa's noise ordinance doesn't set separate decibel limits by zoning district; instead, Title 6, Chapter 12, Section 6-12-3 bans any loud, unnecessary, or unusual sound that disturbs a reasonable person and directs enforcement to weigh the zoning and permitted land use of the source property alongside volume, timing, and duration.

Key details: Standard: Reasonable-person test, no fixed decibel table. Zoning factor: Source property's zoning/land use is a listed factor. Nighttime weight: 10:00 p.m.-6:00 a.m. sounds weighed more heavily. First-offense fine: $250-$1,500 civil sanction. Habitual offender: 3 violations/12 months triggers Class 1 misdemeanor.

A first Section 6-12-3 civil violation carries a sanction of $250 to $1,500 under Section 6-12-10(B). A second finding within 24 months of a prior violation raises the range to $500-$2,500, and a third within 24 months raises it again to $750-$2,500. Each day of violation is a separate offense, and a person found responsible three times within 12 months becomes a habitual offender facing a Class 1 criminal misdemeanor under Section 6-12-11, punishable by up to six months in jail and a mandatory minimum $500 fine per count.

The Bottom Line

Mesa's noise ordinances rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Mesa is broadly strict or permissive.

Keep in mind that Mesa can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
