How Arvada Handles Noise Ordinances: A Practical Guide

Arvada maintains 140 local ordinances across all categories, and 5 of those deal specifically with noise ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Arvada falls on the strict-to-permissive spectrum compared to other cities.

Construction Hours

Arvada bars construction equipment noise in residential, commercial, and mixed-use zoning districts between 9:00 p.m. and 7:00 a.m. under City Code § 38-62(2). During permitted daytime hours, a construction project's noise is capped at the sound-pressure level allowed for light industrial districts under the citywide table in § 38-91.

Key details: Construction noise curfew: 9:00 p.m. to 7:00 a.m.. Daytime noise cap: 70 dB(A), light industrial standard. Nighttime noise cap: 65 dB(A), light industrial standard. Emergency work exemption: § 38-63, safety restoration work. Public infrastructure exemption: § 38-65, city/public-works projects.

Running construction equipment in a residential, commercial, or mixed-use district between 9:00 p.m. and 7:00 a.m. violates § 38-62(2) even if no neighbor complains, and exceeding the light-industrial decibel table during the day is a separate violation of § 38-91. Both are enforced under the chapter's general penalty, § 38-33, applying the § 1-5 fine schedule of up to $2,650 or 364 days in jail.

Amplified Music & Outdoor Sound

Arvada requires a permit before anyone uses a loudspeaker or sound-amplifying equipment, fixed, movable, or mounted on a vehicle, on any street, alley, sidewalk, park, or public or private property under City Code § 38-62(6). Even with a permit, amplified sound is capped by the city's community noise table at 55 dB(A) in residential areas by day and 50 dB(A) at night under § 38-91.

Key details: Permit required for: Fixed or vehicle-mounted loudspeakers. Permit issuer: City manager or designated rep., § 38-35. Residential daytime limit: 55 dB(A), 7am-9pm. Residential nighttime limit: 50 dB(A), 9pm-7am. Plainly audible standard: 25 feet from a parked vehicle.

Operating amplified sound equipment outdoors without a city permit is a specific violation of § 38-62(6), and exceeding the § 38-91 decibel table, or being 'plainly audible' at the property line under § 38-62(8), are independent violations even with a permit in hand if the permit's own limits are exceeded. General violations of the noise chapter are punished under § 38-33 by the § 1-5 fine schedule, up to $2,650, up to 364 days jail, or both.

Compared to other cities, Arvada takes a harder line on amplified music & outdoor sound. The enforcement and penalty structure reflects that.

Vehicle Noise

Arvada bars running a heavy vehicle over 10,000 pounds gross weight, or its auxiliary equipment, for more than ten consecutive minutes while standing in a residential area, and requires every motorcycle built after 1982 to carry an EPA-labeled muffler, under City Code § 38-62(11) and (12). Repairing or testing a vehicle so it causes a noise disturbance is separately unlawful under § 38-62(10).

Key details: Heavy-vehicle idling limit: 10 minutes, over 10,000 lbs GVW. Motorcycle muffler rule: EPA label required, post-1982 models. Horn use: Danger warning only, § 38-62(4). Wedding/sports horn exception: Within 2 hours of event. Enforcement: Traffic stop on reasonable suspicion.

Idling a heavy vehicle over ten minutes in a residential area, repairing a vehicle so it disturbs neighbors, or operating a post-1982 motorcycle without its required EPA exhaust label are each unlawful acts under § 38-62(10)-(12). A motorcyclist who cannot show the EPA label to a police officer on request faces prima facie evidence of a violation at trial. General penalties under § 38-33 apply the § 1-5 fine schedule, up to $2,650 or 364 days in jail.

Barking Dogs

Arvada treats a dog that habitually barks, howls, or yelps as a "nuisance animal" under City Code Section 14-53. A citation requires at least two complaining witnesses from separate households who sign the complaint and testify at trial, unless an animal management officer personally observed the noise or a complainant brings corroborating evidence such as video.

Key details: Governing section: Arvada City Code § 14-53. Trigger: loud, persistent or habitual barking/howling/yelping. Witness rule: 2+ complaining witnesses from separate households. Officer exception: officer's personal observation can replace 2nd witness. Max fine: $2,650.00 (§ 1-5).

A nuisance-animal conviction, including habitual barking, is punished under Section 14-7's reference to Section 1-5: up to $2,650.00 in fines, up to 364 days in jail, or both, with each continuing day potentially a separate offense. Because Section 14-53(d) requires two witnesses from separate households, or an officer's own observation plus corroborating evidence like video, a single complainant cannot get a summons issued alone.

Decibel Limits

Arvada caps stationary noise sources by zone: 55 dB(A) by day and 50 at night in residential and mixed-use districts, 60 and 55 in commercial, 70 and 65 in light industrial, and 75 at all hours in heavy industrial. Day runs 7:00 a.m. to 9:00 p.m. Readings last at least ten minutes and can be taken at the property boundary or anywhere on the affected property.

Key details: Residential and mixed-use: 55 dB(A) day, 50 dB(A) night. Commercial: 60 dB(A) day, 55 dB(A) night. Light industrial: 70 dB(A) day, 65 dB(A) night. Heavy industrial: 75 dB(A) day and night. Day hours: 7:00 a.m. to 9:00 p.m.; night is 9:00 p.m. to 7:00 a.m..

Chapter 38 sets no separate fine for Table I overages. Section 38-33 fills the gap: a person convicted of a violation where no definite fine is provided is punished by a fine not exceeding the limits established in section 1-5, for each offense. Section 38-61 separately makes it unlawful to make or continue any excessive or unusually loud noise or to create a noise disturbance, which needs no meter reading. Relief is available under section 38-35, where the city manager or an authorized representative can grant a permit when prohibiting the noise would cause undue hardship, weighing time of day, duration, loudness relative to the limits and the cost of compliance, and setting dates, hours and sound levels in the permit.

The Bottom Line

Arvada'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 Arvada is broadly strict or permissive.

Keep in mind that Arvada can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, which shows when its source was last checked.
