OnlineRME Septic Records: Search Tips by County

OnlineRME is a shared search platform, not one nationwide septic-file database. The county still controls what records appear, which search keys work, and what to do when nothing is returned. These official county instructions show why the same search can surface different records in different places.

WA

King County, WA

King County separates the collections: its septic-record search covers site designs, historic inspections, and as-built drawings; OnlineRME is the separate route for operation and maintenance records. Time-of-sale reports may carry updated drawings in Application History.

If nothing appears: King County lists address/parcel changes and unscanned microfiche among possible causes and provides a direct as-built help route.

WA

Snohomish County, WA

Snohomish County says OnlineRME includes as-built drawings and service-history reports for current and past septic systems.

If nothing appears: older systems may predate record requirements; the Health Department says additional information may still be on file and accepts records requests.

VA

Loudoun County, VA

Loudoun County recommends selecting Virginia and Loudoun County, then searching with the Tax ID (PIN plus 000) or street number. Its guidance warns that a street-number search may not include all files.

If nothing appears: check the county's separate scanned-record and subdivision parent-file searches, then contact the Health Department.

A reliable search sequence

Match the county, the key, and the file.

Confirm the property county and choose that county inside OnlineRME; do not assume the platform searches every county at once.

Follow that county's own search-key instructions. For Loudoun, try the PIN-plus-000 Tax ID format; a street-number search may be incomplete.

Name the exact artifact you need. In King County, use the separate county search for site designs and as-builts and OnlineRME for operation and maintenance records.

If no file appears, use the county's published fallback: Snohomish says additional older records may be held by its Health Department; Loudoun directs users to contact its Health Department; King County provides an as-built help email and phone route.

A historical record can help explain the property's file, but it does not establish current condition, exact present-day location, or later changes.

FAQ

Before you treat a blank search as an answer.

Does OnlineRME search septic records for every U.S. county?

No. OnlineRME is used by participating jurisdictions. Select the county that holds the property's file and follow that county's search instructions.

Why does King County send me to more than one search?

King County describes its own search for site designs, historic inspections, and as-built drawings, while OnlineRME is a separate route for operation and maintenance records.

What should I do if OnlineRME finds nothing?

Do not assume the county has no record. Try the county-recommended property keys and the county's separate archive or records-request fallback. Older files may not be online.

Does an OnlineRME drawing prove the septic system is in good condition now?

No. A historical drawing or service record is not a current site inspection and may not reflect later changes or present-day condition.
