Governor Gavin Newsom announced on Sep. 20, 2026 that he has signed a set of bills and vetoed others; the Office of the Governor published the full lists.

The signed measures named in the release include legislation across multiple policy areas. Examples from the signed list include AB 643 (Climate change: short-lived climate pollutants: organic waste reduction); AB 2111 (Electricity: transmission planning and transmission facilities); AB 1307 (Licensed Dentists from Mexico Pilot Program); AB 690 (Criminal procedure: indigent defense compensation); AB 1588 (Vehicles: Sideshow Accountability and Community Safety Act); AB 2278 (In‑home supportive services: Community First Choice Option program: noncompliance penalties); SB 58 (Air quality: standard: hydrogen sulfide); SB 691 (Body-worn cameras: policies); and SB 802 (Housing finance and development: Sacramento Regional Housing and Homelessness Joint Powers Authority Act). The governor’s office published the complete list on its website.

The release also lists vetoed bills. Examples from the veto list include AB 539 (Health care coverage: prior authorizations); AB 605 (Employment: refineries: task force); SB 632 (Community colleges: California College Promise); and SB 1180 (Plastic Pollution Prevention and Packaging Producer Responsibility Act: California Plastic Pollution Mitigation Fund). The governor’s veto messages are available from the same office.

Practical consequence; the signed bills create new statutory requirements or pilot programs in areas from waste reduction and air-quality standards to electricity transmission planning, workforce programs and public-safety rules. The specific effects; timelines, funding, regulatory implementation and agency guidance; depend on each bill’s text and follow-up actions by state agencies; those details are not included in the governor’s summary.

What is not yet known; the release does not summarize implementation schedules, budgetary impacts or administrative rules for the bills. For the full text and statutory details, the governor’s office directs readers to the Legislature’s bill texts at leginfo. Veto messages posted by the governor’s office explain his stated reasons for each veto.
