Summary of California Bills Per Session and Actions Taken – 2026 Edition

The following research was updated in October 2026 in order to examine the major actions involving bills in the California Legislature over the past few years. I examined the following five categories of information for each year, as set forth in the chart below:

The number of bills introduced each year of session.

The number of bills passed by the house of origin (e.g., ABs that passed the Assembly Floor) and the percentage of bills passed by the house of origin in comparison to the number of bills introduced.

The number of bills refused passage by the house of origin (e.g., SBs that failed passage on the Senate Floor) and the percentage of bills that failed passed on the floor of the house of origin in comparison to the number of bills introduced.

The number of bills that reached the Governor’s Desk and the percentage of bills that reached the Governor’s Desk in comparison to the number of bills introduced.

The number of bills chaptered (i.e., signed into law) and the percentage of bills that were chaptered in comparison to the number of bills introduced, as well as the percentage of bills that were chaptered in comparison to the number of bills that reached the Governor’s Desk.
