Accessory Dwelling Units

For EPS New Construction

Incentives for Accessory Dwelling Units

Accessory dwelling units (ADUs) are becoming more and more popular as homeowners see the value of having an extra living or rental space on their property. ADUs can also benefit you as a builder. Energy Trust offers performance-based incentives to builders of energy-efficient ADUs that earn an EPS. Qualifying units must meet specific efficiency requirements, and are designed to deliver low energy costs and superior overall performance.

To begin the process, meet with an Energy Trust trade ally verifier during the design phase. The verifier will work with you to make sure your ADU meets Energy Trust incentive specification requirements. Find trade ally verifiers in your area.

An ADU is a structure that is permitted as an accessory dwelling unit by the local jurisdiction and is intended to be used as living quarters. To qualify for incentives, the ADU must receive an EPS and:

  • Be sited in Energy Trust territory
  • Be permitted as an ADU
  • Have its own USPS mailing address separate from the main residence
  • Be intended for use as a primary residence
  • Adhere to square footage limitations set by local jurisdiction
  • Receive its own third-party verification
  • Be built by a builder or owner-builder who is a trade ally with Energy Trust’s Residential program
  1. Establish project eligibility (see Eligibility tab).
  2. Select a third-party verifier in accordance with Energy Trust’s requirements.
  3. Your verifier will inspect your home and perform diagnostic tests to evaluate energy performance.
  4. Once the home has been built and verified, your verifier will update the project model with inspection details and performance results, confirm your incentives and issue the final EPS.
