New California laws taking effect on Jan. 1, 2026, expand coverage for in vitro fertilization, regulate artificial intelligence, protect renters and more
by CalMatters staff
Most of the hundreds of new California laws scheduled to take effect at the start of 2026 won’t dramatically change daily life for most residents. Many are technical updates, cleanup language, or directions to state agencies to carry out policies lawmakers approved in previous years. Still, a smaller but significant group of measures passed in 2025 could have meaningful effects on families, workers, renters, students and consumers across the state.
Among the most personal changes are new requirements expanding insurance coverage for in vitro fertilization. Lawmakers say the goal is to reduce financial barriers for people struggling to conceive and to bring insurance standards in line with modern medical practices. For families navigating infertility, the new rules could determine whether treatment becomes financially accessible.
Education is another area targeted by new legislation. One law pushes more California State University campuses to offer automatic admission to high school seniors who meet academic benchmarks. Supporters say the change will simplify college access, reduce uncertainty for students and families, and strengthen pathways into public higher education at a time when enrollment across the system has declined.
Other laws focus on emerging technologies and housing pressures. California is moving to establish clearer rules around artificial intelligence, including how automated systems may be used and when human oversight is required. At the same time, new renter protections are designed to curb abuses, clarify tenant rights and strengthen enforcement as housing costs remain high in many communities.
Immigration policy also remains a major concern. Several new laws position California to respond to stepped-up federal enforcement, reinforcing the state’s approach to immigrant protections and limits on cooperation with federal authorities.
In total, lawmakers passed 917 bills in 2025, and Gov. Gavin Newsom vetoed 123 of them. Most of the measures he signed take effect on Jan. 1, 2026. CalMatters reporters are tracking the most consequential changes, explaining what they do, who they affect and why they matter to Californians statewide.
