MassDEP states that ordinary Title 5 system inspections are generally required within two years before a sale. Where the system has been pumped annually and proper records exist, a qualifying inspection can remain valid for three years.
Title 5 regulates on-site sewage disposal systems and is designed to protect public health and the environment. The inspection evaluates components such as the septic tank, distribution box, cesspool where applicable, and system condition.
Certain transfers are exempt or governed by special rules, including specified family transfers and some foreclosure, bankruptcy, trust, or ownership-change situations.
Real estate licensees should understand the inspection trigger and disclosure implications but should not attempt to perform or certify the inspection themselves; only approved system inspectors can conduct a valid Title 5 inspection.
