Zero Energy Ready Home Certification for California
A Department of Energy (DOE) Zero Energy Ready Home (ZERH) is a high-performance home so energy efficient that a renewable energy system could offset most, or all the home’s annual energy use. HERS Raters inspect, test and certify ZERH homes through CHEERS, a DOE approved Home Certification Organization.

Industry leading quality and standards
Leading ENERGY STAR certified home builders are looking for the next steps in superior home performance and market differentiation. ZERH takes the homeowner experience to a higher level of efficiency, comfort, health, and durability.


Up to a $5,000 tax credit per address
The Inflation Reduction Act of 2022 amended Internal Revenue Code Section 45L to provide a tax credit for new homes that meet DOE ZERH program requirements.
Builders can receive up to $5,000 per single family new residential home and $1,000 per multi-family dwelling address.
These new 45L rules apply to homes acquired after December 31, 2022, and before January 1, 2033, for use as a residence during the taxable year.

Zero Energy Ready Homes with CHEERS
Like ENERGY STAR, independent verification is a central component of the ZERH program. HERS Raters provide third-party inspection services giving homebuyers confidence that their new home meets the stringent program requirements underlying the nation’s premier federal home efficiency program.
