Septic As-Built Lookup: How to Find the Drawing for Any Property

The as-built drawing is the single most useful document tied to a septic system: it shows the tank location and capacity, the drainfield layout, and the setbacks as actually installed. Looking one up means finding which office holds it and whether that office lets you search. Both vary county by county, and that is exactly what we track.

The three places an as-built can live

• A county or district health department portal. Some jurisdictions publish scanned records online, searchable by parcel or address.
• The health department by request. Many counties hold the file but require a records request by email, phone, or form.
• Our corpus. We hold more than 5.2 million recorded septic documents across 31 states, pulled from public sources and tied to parcels, viewable through the parcel tool.

How to run the lookup

1. Open your county page in our records index. It states where that county keeps septic records, the records system in use, whether anonymous search works, and what we found when we tested the portal directly.
2. If we hold documents for the county, open the parcel map, find the property, and view what is recorded against it.
3. If the county is request-only, the county page tells you who the custodian is where we have confirmed one.

If no as-built exists

Systems that predate consistent record-keeping may have no drawing on file anywhere. In that case the practical substitute is an estimated reconstruction from code tables and nearby recorded systems, which our design generator produces for free. It is estimated, NOT a county-stamped document, but it tells you what is probably in the ground.

Common questions

What does a septic as-built lookup actually return?

The recorded drawing of what was installed: tank location and capacity, drainfield layout and dimensions, soil evaluation results, and setbacks as built.

Is the as-built a public record?

Usually public or semi-public, depending on the jurisdiction. It is filed with the county or district health department at approval, sometimes online and sometimes only by request.

What if my county has no online search?

Our county pages state whether anonymous search works and, where we have confirmed one, who the records custodian is, so you know exactly who to ask.

What if there is no as-built on file at all?

Older systems may have none. A free estimated design from our generator, built from code tables and nearby recorded systems, is the practical starting point. It is estimated, NOT a county-stamped document.
