Democratic Gov. Gavin Newsom has proposed covering immigrants 19 to 25 years old.
A proposal in the state Senate would expand that coverage to include people 65 and older, while the Assembly is considering a bill that would extend benefits to all low-income immigrants 19 and older.
California already covers immigrants 18 and younger regardless of their status.
A final decision on wider coverage may come down to cost.
Newsom estimates his plan covering young adults would cost $98 million a year. Legislative staffers estimate the Senate’s plan could cost $304 million and the Assembly proposal $3.2 billion annually.
Newsom estimates California will have a $21.5 billion budget surplus. But he has urged lawmakers to constrain spending, warning the next recession could cost the state $70 billion in revenue.
