HVIP FAQs and FY22-23 Updates

FAQs are now available to guide participants through the previously-announced FY22-23 HVIP policy changes. See These FAQs help guide participants through important policies and requirements, in advance of the publication of the FY22-23 Implementation Manual.

Fleet Size Adjustments and Bulk Purchase Requirement

Starting in early April, dealers who have requested vouchers for private fleets with more than 500 vehicles above 8,500 lbs (under common ownership or control and domiciled in California) since January 1, 2023 will be contacted by the HVIP Voucher Processing Center Team about their bulk purchase requirement.

Also starting in early April, fleet size adjustments of -20% from the base voucher amount for private fleets with 101-500 vehicles above 8,500 lbs (under common ownership or control and domiciled in California), and -50% for those with more than 500, will be reflected in the online Voucher Processing Center.

These policy changes have been in effect since January 1, 2023 but will be visible in the online Voucher Processing Center, including on the Request Form, starting in early April.

Expanded DAC Definition

Effective for vouchers requested starting April 3, 2023, HVIP defines Disadvantaged Community (DAC) eligibility as a vehicle domicile address in any of the following areas of the map at

  • Disadvantaged Communities (orange area on map legend)
  • Disadvantaged and Low-Income Communities (pink area on map legend)
  • Low Income Communities within ½ mile of a Disadvantaged Community (yellow area on map legend) and
  • Low Income Households within ½ mile of a Disadvantaged Community (green striped area on map legend)

The date of signature on the LOI may be no earlier than January 1, 2023. A purchase order (or other binding agreement) will be required within 6 months of submission, otherwise the voucher requests will be cancelled. A sample LOI is available at
