If you are buying or selling property with a septic system installed, an inspection of the system may be part of the process. Certain types of ownership changes have different requirements.
When are system inspections required?
- Within 2 years before a sale. If weather conditions prevent inspection at the time of a sale, the inspection must take place within 6 months afterward.
- When there is a proposed change to the facility which requires a building or occupancy permit.
- Any change in the footprint of a building, to make sure that new building construction will not take place on top of any system components or on the system’s reserve area.
- For large systems with a design flow of 10,000 to 15,000 gallons per day or more at full build-out, on the basin schedule shown in 310 CMR 15.301(6), and every five years thereafter.
- Every 3 years for shared systems.
- When the property is divided, or ownership of 2 or more properties is combined.
- When MassDEP or the local Board of Health orders an inspection.
