Summary
In residential areas of Beaverton, Washington County, sound between 10 p.m. and 7 a.m. that exceeds 50 dBA at the noise-sensitive area's property line counts as evidence of a loud or raucous noise violation.
If the sound occurs in a residential area between 10:00 p.m. and 7:00 a.m., whether the sound exceeds 50 dBA at a point within the property line of the noise-sensitive area nearest the noise source.
Full Breakdown
Beaverton Code § 5.15.025.B lists seven factors code enforcement weighs to decide if a sound is 'unreasonably loud or raucous,' including proximity to a sleeping facility, time of day, duration, and whether a sound-amplification device is involved. Factor 7 sets a numeric anchor: in a residential area between 10:00 p.m. and 7:00 a.m., whether the sound exceeds 50 dBA at the property line of the nearest noise-sensitive area. There is no city-wide decibel cap for daytime or non-residential noise, those cases turn on the other six factors, not a number.
Violations & Fines
A first violation is a Class I civil infraction under BC 5.15.040; a Beaverton municipal judge can fine up to $1,000 for repeat violations within 24 months, and each day of continuing noise is a separate infraction.
