Buying or Selling a Property With a Septic System

The septic system is usually the least-documented part of a real estate transaction, and the most consequential if it goes wrong after closing. These guides cover the inspection, the records, the lender rules, and the disclosure questions that actually matter, and our state pages tell you where a real transfer-inspection law exists and where it does not. We are not attorneys, agents, inspectors or lenders; the county or state agency, your lender and your own inspector are authoritative.

Transfer requirements by state

Whether the state (or, for New Hampshire, a defined class of property) has a verified, real time-of-transfer septic inspection law, and where its septic records are held, county by county.
