Are CalHFA ADU grants open?
CalHFA’s latest California ADU grant round is fully allocated. Its program page still displays the December 28, 2023 update when read 2026-11-04. The agency links to ADU eNews updates; an older description of the grant does not establish that another application round is open. Treat the published cap as a program description, rather than a current reservation.

Who is eligible for CalHFA ADU grants?
“Homeowners with incomes less than CalHFA income limits.”
CalHFA’s California eligibility infographic points homeowners to the agency’s income limits. The term sheet also calls for an owner-occupancy affidavit and a rental or intergenerational housing purpose. Those are program conditions, rather than a determination about a particular household. The latest round remains fully allocated; meeting the described conditions does not open that round.

What costs do CalHFA ADU grants cover?

Keep that category separate in a project scope from construction of the dwelling itself. The cap describes the agency program; the fully allocated status still governs the latest round.
