Full Breakdown
HMC 6.20.020 sits in the Animals subchapter and applies to any animal noise, not just dogs. Subsection (A) sets the trigger with actual duration thresholds: the sound has to be shown to have occurred either as continuous noise lasting a minimum of 10 consecutive minutes, or intermittently for a minimum of 30 minutes, and it has to be audible beyond the boundary of the keeper's property. Subsection (B) gives the keeper an affirmative defense if the animal was intentionally provoked into making the noise by someone other than the keeper. Subsection (C) exempts an animal-services facility that is authorized under the City's land use and zoning regulations from the noise standard entirely. Subsection (D) folds a noise violation into the City's broader nuisance framework: causing, permitting or allowing a nuisance involving the keeping of an animal, toward a person, property or another animal, on public or private property, is a violation whenever a person breaches the standards in HMC 6.20 or HMC 6.28.
Dogs specifically also fall under Washington County's dog code: HMC 6.20.050(A) states that the City "consents, pursuant to ORS 203.040, to the applicability in the City of the provisions of county code chapter 6.04, except as otherwise specifically provided in the Code," and the City Manager and Recorder are authorized to execute intergovernmental agreements to implement and enforce that county chapter within city limits. A nuisance complaint under 6.20.020 is handled through the abatement process at HMC 6.28.020: the Manager mails and posts a notice giving up to 15 days to abate, and can then file an action in municipal court under HMC 4.04 if the noise continues, on top of the standard $500.00 municipal code fine under HMC 1.08.010(B).
Violations & Fines
A substantiated animal-noise complaint triggers HMC 6.28.020's abatement notice process: mailed and posted notice describing the noise and giving up to 15 days to stop it, then a municipal court filing under HMC 4.04 if it doesn't stop. Independent of abatement, an animal-noise violation carries the City's standard $500.00 penalty under HMC 1.08.010(B), and HMC 1.08.030 makes each day the disturbance continues a separate, separately punishable offense.
