What Are Mass Save New Construction Rebates?
Mass Save is Massachusetts’ statewide energy efficiency program, funded by the major electric and gas utilities. The Mass Save New Construction program offers cash rebates and incentives to builders and developers who build homes that exceed the energy code minimum. Rebates are tied directly to your HERS score — the lower your score, the higher your rebate.
How Much Are Mass Save New Construction Rebates in 2026?
Mass Save new construction rebate amounts vary by HERS score tier and are updated periodically. In general, rebates increase as HERS scores decrease below the Stretch Code minimum of 55. Projects that achieve a HERS score of 45 or below, or that pursue the MA Specialized Opt-In Code pathway, may qualify for larger incentives. Contact Mass Save or a Mass Save-approved HERS Rater like HERS Rating Company for current rebate levels specific to your project.
Who Qualifies for Mass Save New Construction Rebates?
To qualify for Mass Save new construction rebates in Massachusetts, you need: a HERS Rating performed by a Mass Save-approved HERS Rater; a HERS score that meets the rebate threshold (typically below 55 for the Stretch Code tier, lower for enhanced tiers); and a final blower door test and duct leakage test that meet Stretch Code requirements. Both single-family and multifamily new construction projects are eligible.
How Does the Mass Save Rebate Process Work?
The Mass Save rebate process for new construction works as follows: engage a Mass Save-approved HERS Rater early in the design phase; the HERS Rater registers the project with Mass Save and performs energy modeling; during construction, the HERS Rater conducts required inspections; after construction, the HERS Rater performs the final blower door test and HERS certification; the Mass Save-approved HERS Rater submits the incentive application on your behalf. Payment is typically received within 4–8 weeks of project completion.
