Failed Title 5 Septic Inspection in Massachusetts? What Now
In Massachusetts, most homes with a septic system need a Title 5 inspection before they can be sold. If the system fails, it generally must be upgraded within two years, and buyer and seller negotiate who pays. State tax credits and low-interest loans can help cover the cost.
What to look for
- Sewage odors in the yard or house
- Soggy ground or bright green grass over the leach field
- Slow drains or gurgling pipes
- Sewage backing up into the basement or tubs
- Tank needing pumping much more often than normal

Who to call
- A MassDEP-approved Title 5 system inspector (your local board of health can confirm who is approved)
- Your local Board of Health, which approves septic repair plans and permits
- A registered sanitarian or professional engineer to design the new system; check a PE at the state ePlace lookup (source: elicensing21.mass.gov)
- A licensed septic installer approved by your town's board of health
DIY or hire a pro?
Homeowners can keep up with pumping and avoid parking or building over the leach field. The Title 5 inspection, design and any repair or replacement must be done by approved professionals with board of health permits.
If fixing it is more than you want to take on
You can repair the system and then list, or sell with a failed Title 5 and negotiate the cost into the price (the buyer then takes on the 2-year upgrade with board of health approval). You can also sell as-is to a cash buyer who takes on the upgrade; it's simpler and faster, but the price will reflect the full septic cost and then some.
