The credit is available only for qualifying expenses to an existing home, either an addition or renovation vs. new construction. The credit is nonrefundable, meaning homeowners cannot get back more from the credit than what is owed in taxes; any excess credit cannot be carried into future tax years either.
The HOMES rebate is based on Area Median Income (AMI). Rebates are doubled for low- and moderate-income households (LMI) (individuals making less than 80% of area median income) to help those with the highest energy burdens to better-afford upgrades. Retrofits that achieve modeled energy savings of 20 to 35% are eligible for a rebate of 50% of the project costs, up to $2,000. Retrofits that achieve modeled savings >35% are eligible for up to $4,000. The rebates increase to 80% of costs up to $4,000 and $8,000 for households at <80% AMI. Multifamily buildings are also eligible.
In addition to robust rebates for LMI households, state HOMES programs can also reward those who work on energy efficiency in underserved communities. Note: Contractors operating within the program can claim a $200 rebate per underserved home they work on.
Applicants, either homeowners or contractors, can demonstrate savings by comparing energy consumption before and after the retrofits through one of two ways. One method is to use energy models that estimate the energy performance of the whole house; the other is to measure performance.
