Buying or Selling a Septic Property in Iowa

Iowa has a real, statewide septic transfer-inspection requirement: Iowa's Time of Transfer law, in effect since July 1, 2009, requires most homes and buildings served by a private septic system to be inspected before the property is sold or transferred, so that substandard systems (no secondary treatment, or a failed secondary treatment component) get identified at the point of sale rather than left for the next owner to discover.

What the law requires

Law: Time of Transfer Inspection Law (Iowa Code 455B.172(11); IAC 567-69.2).

Timing: Inspection happens before the sale or transfer closes; a handful of transfer types are exempt, including court-ordered transfers, foreclosures, and transfers by eminent domain.

Who's responsible: A DNR-certified Time of Transfer inspector performs the inspection; the report is transmitted automatically to both the Iowa DNR and the county where the property sits.

Where do I find septic records for a Iowa property before closing?

At the county or district health office that issued the permit, in almost every case. See the county-by-county index on this page for Iowa, and our general guide to finding records before closing.

Reviewed 2026-08-31 against the official sources linked above (where a source is cited) or, where none is cited, left deliberately general. Laws, lender overlays and local ordinances change; confirm current requirements with the county or state agency, your lender, and a licensed inspector before you rely on this for a closing.
