Noise

All residents and visitors to Forest Grove have the right to a safe and comfortable atmosphere in which to live, work, and enjoy. Noise can be a concern especially if it exceeds the maximum decibels (dBA).

Report Noise Violations

To report a noise violation, please contact Washington County Dispatch at 503-629-0111 while the incident is occurring - as officers must witness the violation in order to take action. Measurements of sound levels are taken from the complainant's property.

Maximum Allowable Sound Levels - Day & Night

It's important to know that noise and sound regulations are in effect 24 hours a day, not just during the night or "quiet hours." The maximum level of dBA allowed varies depending on the time of day, as well as the type of zoning.

As a general rule, noise during the day, from 7 a.m. - 10 p.m., in residential areas may not exceed 60 dBA. 

Noise in residential areas overnight, from 10 p.m. - 7 a.m., cannot exceed 50 dBA. 

Commercial and industrial areas have a maximum of dBA of 80 during the day and 70 at night.
