The page specifies batt and roll insulation only, lists $0.50/sq. ft. above R-19 and $0.30/sq. ft. at R-19 or below, and separately advertises an extra $0.25/sq. ft. launch special. Obtain confirmation of the payable total rather than silently treating those figures as already combined.
Apply: Check material and attic-clearance rules first. Keep paid invoices, product ratings, required contractor records, before/after photographs, and the finaled permit. Eligible work must be purchased/installed on or after September 1, 2025. Submit the paper application within 12 months of the applicable purchase/self-install or contractor-install date. Funding is limited and duplicate California utility rebates for the same product are restricted.
