Massachusetts has a real, statewide septic transfer-inspection requirement: Massachusetts is one of the few states with a real statewide mandate: with narrow exceptions (transfers between certain family members, property held in trust, and a few other categories listed in the regulation), a septic system must be inspected at the time title to the property transfers.
Law: Title 5 of the State Environmental Code (310 CMR 15.301).
Timing: The inspection generally must have been performed within 2 years before the sale closes, or within 3 years if it is paired with records showing the tank was pumped at least once a year in the interim.
Who's responsible: A DEP-approved Title 5 system inspector performs the inspection and files the official inspection form; hiring the inspector is a matter of local practice, not a statutory assignment, though sellers commonly arrange it.
Massachusetts Department of Environmental Protection (MassDEP), Bureau of Water Resources (state code owner "Title 5"); local Boards of Health administer/enforce. See the full Massachusetts septic regulation page for the permit sequence and licensing.
Wherever you're transacting in Massachusetts, the septic permit or as-built (where one exists) is almost always held by the county or district health office, not the state. How to find septic records before closing covers how to pull it; below is the county-by-county index of what we hold for Massachusetts.
