Idaho Window and Sliding Glass Door Rebates for Multifamily Homes

Expiration notice: Effective January 1, 2027, offerings for Idaho gas-powered homes are ending. Eligible projects must be completed by Dec 31, 2026. Applications and documentation must be received no later than January 15, 2027.

This change is happening because Idaho rules require energy-efficiency programs to provide enough savings to justify the cost of the program. At current natural gas prices, these Idaho natural gas rebate and incentive programs no longer meet that standard.
