PLAN WITH A CLEARER PICTURE
Find official septic records resources for Linn, Benton, Lane, Polk, Marion, and Yamhill counties and prepare a useful project handoff.
An existing permit, system drawing, or service report gives your project team useful context. Online files may be incomplete, and an old drawing does not confirm a system’s present condition.
Keep the property address, parcel or tax-lot number, and any existing permit number handy. Use this information directly with the county.
Some counties provide online searches; others explain how to request records from staff. Follow the official resource for your county below.
Save the records you find with your inspection, pumping, and repair reports. Note any gaps or differences you want to discuss with your provider.
Describe what you want to change, then ask On-Site and the county what information is needed to establish the next step.

When introducing a project, include the proposed work, county, available site plans, existing septic information, and the people coordinating the next step. Share customer records only with the people involved and with the owner’s permission.
A records review supports planning. Confirm current system condition, project requirements, and responsibilities with the appropriate professionals.
Contact the county program with the property identifiers and ask about other available records. The Marion County program, for example, explains that its online septic history is incomplete.
Keep the installation drawings, permit and completion records with service reports. Lane County’s inspection guidance explains the value of retaining the completion certificate and final inspection report for future repairs.
Yes. Describe your goal, location, existing records, and where you are in planning. On-Site can discuss what information would help establish the next step; the scope, estimate, and timing still need to be confirmed directly.
Finished plans are not required to start a conversation. Share the work you have in mind, your property’s county, and the records available.
Discuss your projectFor an urgent concern, call (503) 362-7000 to check availability. An online request does not arrange emergency dispatch.
