Do you need a state license in Massachusetts?
Massachusetts does not issue a statewide septic installer license. Any license you need comes from the city or county where the job is, so the rules can change from one town to the next.
The local approving authority is the board of health, or its agent or a health district acting for it. It issues permits only to installers who show knowledge and experience with Title 5 systems.
How to get set up in Massachusetts, step by step
- Contact the board of health in each town where you will work.
- Show the board your knowledge and experience with Title 5 systems.
- Get the Disposal System Installer's Permit before you work.
- Renew it at least every two years.
