California lawmakers return for final month of 2026 session

California lawmakers return to Sacramento on Monday, August 3, for the final month of the 2025-26 legislative session. The remaining weeks will determine which pending measures clear fiscal committees, reach floor votes and ultimately go to the Governor.

The official 2026 tentative legislative calendar, revised March 27, sets four major deadlines: fiscal committees must meet and report bills to the floor by August 14; floor-session-only days run from August 17 through August 31; August 21 is the last day to amend bills on the floor; and August 31 is the last day for each house to pass bills. The Assembly‘s events calendar lists its regular session for 1 p.m. Monday.

The deadlines residents should watch

• August 3: The Legislature reconvenes from summer recess.
• August 14: Fiscal committees must meet and report bills to the floor.
• August 17-31: The Legislature enters a floor-session-only period. Conference and Rules committees are the exceptions.
• August 21: Final day to amend bills on the floor.
• August 31: Final day for each house to pass bills. Final recess begins after adjournment.
• September 30: Deadline for the Governor to sign or veto bills passed before September 1 and in the Governor’s possession on or after September 1.

These dates create a compressed path for measures that remain in committee. A bill still awaiting fiscal review must be heard and reported by August 14 before it can proceed to a floor vote. The schedule does not guarantee that a pending measure will receive a hearing or vote.

What can still move

Current legislative records show resident-facing measures at different stages of the process.

AB 306, concerning appeals and interpretations of building standards, is in the Senate Appropriations Committee with a hearing listed for August 3. The measure could affect how building-code disputes are handled on housing and construction projects, but it remains an active bill in committee and has not become law.

SB 1205, concerning retention payments for architecture and engineering services on public contracts, is in the Assembly Appropriations process after passing the Senate and the Assembly Governmental Organization Committee. The bill’s status matters to design professionals, public-project contractors and public agencies, but committee approval and passage by one house do not establish a new requirement.

AB 2106, concerning malpractice actions involving architects, engineers and surveyors, is in the Assembly floor process. The legislative record showed Assembly concurrence in Senate amendments pending, with the matter listed on the Assembly daily file for August 3. That makes it farther along than a bill awaiting fiscal review, but it still must complete the legislative process before it can reach the Governor.

AIA California, an industry advocacy organization, identified AB 306, SB 1205 and other housing and professional-regulation measures as priorities in a July 22 update. Its account provides advocacy context; the Legislature’s official bill records are the basis for the measures’ current status.

Why the final weeks matter statewide

The deadlines affect more than Sacramento. Pending legislation can influence housing approvals and construction costs, public contracting, professional regulation, consumer protections, utilities, education, health programs and state or local spending. The practical effect of any measure will depend on its final language, whether it advances through both houses and whether the Governor signs it.

The Assembly’s public schedule lists hearings and meetings after lawmakers return involving agriculture, environmental policy, health, cybersecurity, consumer protection, human services, utilities, housing and oversight. Those listings do not by themselves show that a particular bill will advance. Residents should check the bill’s official record, committee agenda and daily file before assuming that a proposal remains eligible for passage.

Passage is not the same as becoming law

Even if a bill passes both houses by August 31, it is not automatically law. The Governor may sign or veto it. The official calendar lists September 30 as the signing or veto deadline for bills passed before September 1 and in the Governor’s possession on or after September 1.

Effective dates can differ. Some measures may take effect January 1, 2027, while urgency statutes, tax levies and other bills can be governed by different rules. Residents should not treat a bill’s passage, a committee hearing or a listing on a legislative calendar as proof that a new rule is already in effect.

Bill locations, hearing dates and floor schedules can change quickly during the final weeks. Residents tracking measures affecting their communities, workplaces, schools, housing costs or public services should use the Legislature’s official bill-status pages, daily files and committee agendas.
