Title 5 Inspection
The state-required inspection before a property changes hands, performed by a MassDEP-certified System Inspector.
Massachusetts Title 5 requires a septic system inspection when a property changes hands. The inspection must be performed by a MassDEP-certified System Inspector, and it must have been done within two years before the sale. That window extends to three years if the system has been pumped annually and the records exist.
A closing does not move forward without a passing report on file, so the inspection sits directly on the critical path of the sale. This is the one septic job with a hard deadline attached.
Book the inspection early. Inspectors book out, and a failed report means a design and a permit before the sale can move again.
