Sedona's Noise from Specific Sources: The Rules That Matter

Every city handles noise from specific sources a little differently. In Sedona, Arizona, there are 3 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.

HVAC & Mechanical Noise

Sedona exempts properly functioning air-conditioning, pool and spa equipment from its noise level regulations entirely, so long as it runs according to the manufacturer's specifications. Malfunctioning or improperly maintained units lose that protection.

Key details: AC/pool/spa exemption: Full exemption if properly functioning. Governing section: SCC 8.25.030(A)(1). Condition: Per manufacturer's specifications. If malfunctioning: Subject to standard dB limits. Residential nighttime cap (if not exempt): 50 dB(A).

HVAC, pool or spa equipment that is not properly functioning per manufacturer specifications loses the SCC 8.25.030(A)(1) exemption and becomes subject to the community noise standards in SCC 8.25.030(C); exceeding those decibel limits for more than five minutes (residential) or 15 minutes (commercial/industrial) is enforceable under the noise chapter's penalty provision, SCC 8.25.070.

If you are coming from a city with tighter rules, you will find Sedona gives residents more flexibility on hvac & mechanical noise.

Generator Noise

Sedona exempts emergency generators, along with safety signals, alarms, storm sirens and pressure relief valves, from its noise level regulations, including their authorized testing. Non-emergency generator use is not covered and can be measured against the standard decibel limits.

Key details: Emergency generator noise: Exempt, SCC 8.25.030(A)(5). Authorized testing: Also exempt. Grouped exemptions: Alarms, sirens, pressure relief valves, horns. Non-emergency generator use: Not exempt, standard dB limits apply. Residential daytime cap: 60 dB(A).

A generator that is not an emergency backup unit, or that runs beyond authorized testing, loses the SCC 8.25.030(A)(5) exemption and is measured against the community noise standards in SCC 8.25.030(C); exceeding the applicable decibel limit for more than five minutes in a residential area is enforceable under the chapter's penalty section, SCC 8.25.070.

Sedona is more permissive than most cities when it comes to generator noise. That said, there are still limits.

Car Alarm Limits

Sedona requires exterior burglar alarms on buildings and motor vehicles to shut off within five minutes for continuous sound or 15 minutes for intermittent sound. The alarm rule overrides the normal decibel-based noise standards entirely.

Key details: Continuous sound limit: 5 minutes maximum. Intermittent sound limit: 15 minutes maximum. Covers: Building and motor vehicle alarms. Decibel standard: Does not apply while alarm sounds. Civil penalty: Up to $2,500 per offense.

Letting a burglar or vehicle alarm exceed the five-minute continuous or 15-minute intermittent limit is a civil violation under SCC 8.25.070(A)(1), carrying a penalty of up to $2,500 per offense with each day of continuing violation treated as a separate offense. An owner found responsible for three or more such violations within 24 months is a habitual offender under SCC 8.25.070(A)(2), subject to a class 1 misdemeanor charge, up to six months in jail, and a mandatory minimum $500 fine per count.

The Bottom Line

Compared to many U.S. cities, Sedona gives residents more room on noise from specific sources. 2 of the 3 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.
