Inspections

When are system inspections required?

  • The inspection must occur less than two years before the sale of the house. If weather conditions prevent inspection at the time of the sale, the inspection must occur within six months after the sale.

  • 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.
