We have not verified a statewide law in Connecticut requiring a septic inspection at the time a property transfers. That does not mean no requirement applies where you're buying: county and municipal time-of-transfer ordinances exist in various places around the country outside the states with a statewide law. Check the county page below, and ask the local health department directly — that is the authoritative source for a local ordinance, and this page is not.
No statewide Connecticut law requiring septic inspection at time of transfer. Three states do have a real, verified one — Massachusetts, Iowa, and a waterfront-only law in New Hampshire — for comparison; Connecticut is not one of them, at least not at the state level. A county or municipality in Connecticut could still have its own ordinance we have not audited; the local health department for the specific county is the authoritative source.

Wherever you're transacting in Connecticut, the septic permit or as-built (where one exists) is almost always held by the county or district health office, not the state.
