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.

The county is genuinely mixed: 14,628 of 29,777 classified parcels are on septic and the rest are sewered. Which side of that line a Hudson address falls on is worth establishing before anything else. The county publishes a records portal that we were able to search without creating an account, which makes checking a specific parcel something you can do yourself in a few minutes.
