Septic records are almost never filed by street address. They are filed by parcel, by permit number, or by owner name at the time of permitting. Finding the records for an address means translating the address into the identifier the county actually uses, and then knowing where that county keeps its files.
Every county assessor maps addresses to parcel numbers. Our parcel tool does the same thing on a map: search the address, land on the parcel, and see what is recorded against it, including septic-versus-sewer classification where we have it.
Which office holds septic records varies by state and county: sometimes the county health department, sometimes a multi-county health district, sometimes a state environmental agency. Our records index covers 2,388 counties across 49 states and lists, per county, where the records are kept, the records system in use, and whether anonymous search works.
Where the county publishes records online, the county page links the route we verified. Where we hold the documents ourselves, part of a corpus of more than 5.2 million recorded septic documents across 31 states, they are viewable through the parcel tool. Where the county is request-only, the page names the confirmed custodian where we have one.
Start from the address on the live map, or start from the county in the records index. Both roads end at the same documents.

Usually not directly. Counties file by parcel, permit number, or historical owner name. Translate the address to a parcel first; the county assessor or our parcel map does that.
It varies: a county health department, a multi-county health district, or a state agency. Our index states the answer per county for 2,388 counties across 49 states.
Often yes where a public portal exists. Request-only counties sometimes charge copy fees; the county sets those.
It may be on sewer, or the system may predate record-keeping. The parcel map shows septic-versus-sewer classification where we have it, and a free estimated design can reconstruct a likely system where no file exists.
