Inspection requests must be received before 6 a.m. the day of the inspection. You may ask for an inspection by calling the Inspection Request Line at 503-742-4720. We do not make appointments, but do attempt to honor requests for morning or afternoon inspections. Because of the uncertainties in the amount of time required, however, we cannot guarantee a specific time of day. If the dwelling is occupied, the applicant or an adult must be present to let in the inspector and remain during the inspection.
