Residential Renovations and Additions

Incentives for upgrading single-family or multi-family homes (3 stories or less)

The Massachusetts Residential New Construction Renovations & Additions Path promotes energy-efficient upgrades and new additions to homes within Program Sponsor service territories. Incentives are available for homes that meet program eligibility requirements.

Is Your Project Eligible?

Most residential renovation and addition projects at single-family and multi-family homes with three stories or less are eligible if they are located within Program Sponsor service territories.

Eligible upgrades may include, but are not limited to:

  • Insulation
  • Heating, ventilation, and air conditioning
  • Water heating equipment
  • Windows
  • Lighting
  • Air and duct sealing

How Incentives Are Calculated

Incentive eligibility depends on whether the home meets minimum energy savings requirements. Incentives are determined by the amount of electric savings, fuel savings (natural gas, propane, or oil), and overall performance compared to the program baseline. Participating homes are eligible to receive no-cost LED bulbs.

Here's how it works:

  • 1 Pre-construction Home. During an initial site visit, Mass Save calculates how much energy your home currently uses.
  • 2 Baseline Home. Using advanced software, Mass Save calculates energy savings for both the renovated portion of the home and the new addition.
  • 3 Post-construction Home. Mass Save calculates how much energy your updated home uses.

If your renovation or addition incorporates energy efficiency upgrades, you may qualify for incentives.
