Due to budget constraints, Portland Permitting & Development's Septic Program has limited staffing. As a result, we are experiencing occasional delays in scheduling site evaluations, permit plan review timelines, and inspection activities. We appreciate your patience and understanding.
To receive updates and other program news, please email septic@portlandoregon.gov. Updates are expected to be infrequent and sent when we anticipate temporarily reduced staffing so that you can plan accordingly.
The City of Portland has an intergovernmental agreement with Multnomah County and the State of Oregon Department of Environmental Quality (DEQ) to serve as the regulatory agency overseeing the administration of DEQ’s On-Site Wastewater Treatment Systems Rules, commonly referred to as Oregon septic code, for all of Multnomah County.
The City of Portland reviews projects that may impact septic systems in the City of Portland, City of Gresham, City of Maywood Park, City of Troutdale, City of Fairview, Corbett, Cascade Locks, Scappoose, and unincorporated Multnomah County.
