Septic permitting and record keeping happen at the county level, not the city level, which is why every figure below is attributed to the county and linked back to the county page it came from.

We have not yet collected septic documents from Dane County, Wisconsin, so for a Madison 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 genuinely mixed: 58,564 of 162,716 classified parcels are on septic and the rest are sewered. Which side of that line a Madison address falls on is worth establishing before anything else. We have not found a published online records portal for this county, which means the file is requested from the county directly rather than searched.
