Arvada, CO Environmental Rules: Vehicle Idling Restrictions (2026)

The limit sits in Section 38-62(11) of the noise chapter, one of twelve specific acts Section 38-62 declares unlawful under the city's general noise prohibition in Section 38-61, which bars any 'excessive or unusually loud noise' or 'noise disturbance' inside city limits. The idling rule targets heavy trucks and their auxiliary equipment (refrigeration units, generators, power take-offs) standing more than ten consecutive minutes in a residential district, whether parked on a public right-of-way or sitting on private residential property outdoors. Parking the same truck inside a fully enclosed garage or structure removes it from the restriction, and the ten-minute clock is consecutive, so a driver can make repeated short stops without tripping the limit as long as no single stop runs past ten minutes.

The Arvada Police Department enforces Section 38-62 as part of its routine noise-complaint response; there is no separate idling citation form, officers write the violation under this subsection. 00, imprisonment of up to 364 days, or both, with each day a truck keeps idling past the limit charged as a separate offense under Section 1-5(d)'s continuing-violation clause.
