We have not yet collected septic documents from Wayne County, Michigan, so for a Dearborn property the county's own file is currently the only route. This page is about getting you to it, not about pretending we hold something we do not. The county is predominantly sewered: only 19,965 of 554,694 classified parcels are on septic. Septic properties near Dearborn are the exception, which is exactly why owners often do not know they have one. The county publishes a records portal, but reaching the documents needs an account or a login, so budget for that step rather than expecting an open search.
