Arapahoe County, CO Noise Ordinances: Barking Dogs (2026)

Arapahoe County Animal Services Resolution No. , or for a cumulative total exceeding one hundred twenty minutes in any 24-hour period. The rule is enforced by the Arapahoe County Sheriff's Office, which took over sole enforcement of Animal Services regulations effective June 21, 2025. No citation can be issued on a first complaint: the owner or keeper must first receive at least one written warning, after which a citation may follow for any violation occurring seven or more days later without a further warning. Section 4(B) also imposes a corroboration requirement modeled on the county's general "dog at large" evidentiary standard: no citation or conviction can result unless two complaining witnesses from separate households have given formal statements, unless either an Animal Services Officer personally observed and can testify to the noise, or the complainant presents audio or video recording corroborating the violation at the time of the complaint.

Repeated offenses are counted cumulatively only within a rolling 365-day period from the date of the last violation (Section 4(D)). 5), with the resolution's own graduated fine schedule applying instead, $50 for a first offense, $100 for a second, $300 for a third, and a mandatory court appearance for a fourth or subsequent offense, per Section 15(D). This provision governs only unincorporated county land; it does not reach dogs in Aurora, Centennial, Littleton or the county's other incorporated cities and towns, which enforce their own municipal noise codes.
