Noise disturbances during the day requiring noise monitoring (off-road vehicles, commercial activity in a residential area, etc.) should be reported to Code Enforcement at (503) 373-4333. County noise regulations require that a citizen provide proof, in the complaint, that he/she made a good faith effort to contact enforcement authorities while the disturbance was occurring. Ifstaff does not observe the disturbance, the complaint must be signed by two individuals who represent at least two properties within 500 yards of where the violation occurred.If possible, please use the Yes, if the noise disturbance is not observed by either Code Enforcement staff or other Sheriff’s Office personnel. As noted above,in those situations the complaint must be signed by two individuals who represent at least two properties within 500 yards of where the violation occurred. However, complainant information is kept strictly confidential. A few thoughtful questions to your neighbors might help you avoid conflicts and intervention from the Sheriff’s Office or Code Enforcement: 1) Ask your neighbors if any exterior noises (that seem “ok” to you) are disturbing them; 2) Get to know your neighbors and their schedules, i.e. day sleepers; and 3) When you stand outside with the doors and windows shut can you hear your stereo, TV, or other? A little consideration goes a long way in neighbor-to-neighbor relations. Planning Division (503) 588-5038 handles zoning including home-based businesses; mass gatherings, gravel operations, etc. Sheriff’s Office (503) 588-5032 handles evening or nighttime complaints.
