The California Legislature is the state’s lawmaking branch, a full-time bicameral body of 120 elected members who write the statutes governing nearly 40 million residents. It splits into an 80-member Assembly and a 40-member Senate, both meeting at the State Capitol in Sacramento, and it moves legislation through committee hearings, floor votes in each chamber, and the governor’s signature.
Two Chambers, 120 Members
The Assembly seats 80 members, each representing a district of roughly 494,000 people. The Senate seats 40, each representing about 988,000 residents.1California State Senate. Senators
Assembly members serve two-year terms, and every seat is on the ballot in even-numbered years. Senators serve four-year terms on a staggered schedule, so only half the Senate faces voters in any given cycle.2Justia Law. California Constitution Article IV – Legislative – Section 2 That stagger gives the Senate a degree of institutional continuity the Assembly, which turns over entirely every two years, sometimes lacks.
Who Can Serve and For How Long
Under Proposition 28, approved by California voters in 2012, anyone first elected to the Legislature after that date may serve a lifetime maximum of 12 years.3Office of the Chief Clerk. Elected Officials Those years can be spent entirely in one chamber or split between the two in any combination. A member could serve six two-year Assembly terms, three four-year Senate terms, or a mix.
Before Proposition 28, members faced separate caps in each chamber rather than a single combined limit. Legislators already serving when the measure passed remain under the older rules.4California Legislative Analyst’s Office. Proposition 28 – Limits on Legislators Terms in Office – Initiative Constitutional Amendment
To run, a candidate must be a United States citizen, a California resident for at least three years, and a resident of the district they seek to represent for at least one year before the election.2Justia Law. California Constitution Article IV – Legislative – Section 2
Leadership and Pay
Each chamber elects its own leaders. The Assembly chooses a Speaker; the Senate elects a President pro Tempore. Both control committee assignments, shape the agenda, and decide which bills get priority. Majority and minority leaders in each chamber run floor strategy and coordinate their party’s positions.
California legislators earn an annual base salary of $134,694, effective December 2025, placing them among the highest-paid state legislators in the country.5CalHR. CCCC Salaries The independent Citizens Compensation Commission sets legislative pay. Members also receive a per diem allowance for living expenses while the Legislature is in session.
The Session Calendar
The Legislature works in two-year sessions, each following a structured calendar set by the Joint Rules and the state constitution. A few 2026 deadlines show the pace:
- February 20: Last day to introduce new bills.
- May 29: Last day for each house to pass bills that originated in that house.
- June 15: Constitutional deadline for passing the state budget.
- August 31: Last day for either house to pass any bill.
The Legislature typically takes a summer recess in July and reconvenes in early August for the final push before the August 31 cutoff.6California State Senate. Legislative Deadlines The session adjourns at the end of November, and the next two-year session convenes in early December.
From Bill to Law
Every bill starts with a single author, either an Assembly member or a senator. Once introduced, it gets a number and a first reading, which is simply the reading of the bill’s title on the floor. The Rules Committee of that chamber then assigns it to a policy committee based on subject matter.7California State Senate. Legislative Process
The policy committee is where most of the real work happens. It holds a public hearing, takes testimony from supporters and opponents, and votes on whether the bill should advance. The committee can amend the bill before voting. If the bill would cost the state money, it moves next to the Appropriations Committee for a fiscal review before heading to the full chamber.
On the floor, the bill gets a second reading, when additional amendments can be offered. It then advances to third reading, where the author presents it for a final vote. Most bills pass with a simple majority: 41 votes in the Assembly or 21 in the Senate. Urgency measures and appropriation bills require a two-thirds vote: 54 in the Assembly or 27 in the Senate.8California State Assembly. Legislative Process
Once a bill passes its house of origin, it crosses to the second chamber and repeats the process: committee review, floor debate, and a final vote. If the second house amends the bill, it returns to the first house to approve the changes. When both chambers agree on identical language, the bill goes to the governor.
Committees carry the heavy lifting. Each focuses on a specific policy area, such as health, education, judiciary, or transportation, and develops the specialized knowledge to evaluate bills in that field. The committee chair, typically a member of the majority party, controls the hearing calendar and decides which bills get a hearing. A bill that never gets scheduled is effectively dead.
Where Bills Quietly Die
Bills with a price tag face extra scrutiny in the Appropriations Committee. If a bill would cost $50,000 or more from the General Fund, or $150,000 or more from a special fund, it goes on the “suspense file” rather than getting an immediate vote.9Senate Appropriations Committee. FAQs The suspense file lets the committee weigh the combined fiscal impact of all pending bills before the deadline to send them to the floor.
At a vote-only hearing shortly before the fiscal committee deadline, the committee either advances each suspended bill or holds it in committee. Bills held on the suspense file effectively die there. It’s one of the quieter chokepoints in the process, and it kills a significant number of bills every session with little public attention.
What the Governor Can Do
Once both chambers pass a bill, the governor has three options: sign it, let it become law without a signature, or veto it. During the regular session, the governor generally has 12 days to act, and inaction within that window lets the bill become law automatically. For bills reaching the governor’s desk after the Legislature adjourns for the year, the deadline extends to September 30.10California Legislative Information. California Constitution Article IV – Section 10
The governor also holds line-item veto power over appropriations, meaning individual spending items in a budget bill can be struck or reduced while the rest is signed into law. For non-appropriations bills, it’s all or nothing.10California Legislative Information. California Constitution Article IV – Section 10
The Legislature can override a veto with a two-thirds vote of both houses, but this almost never happens. The last successful override was in the 1979–80 session. In practice, a California governor’s veto is close to final.
Kinds of Legislation
Not everything on the floor is a standard bill. The main categories:
- Regular bills, the most common type. If signed, they take effect the following January 1.
- Urgency bills, which address public health, safety, or welfare. They take effect immediately upon the governor’s signature but require a two-thirds vote in each house to pass.11California State Capitol Museum. Life Cycle of a Bill
- Constitutional amendments, which propose changes to the state constitution. They require a two-thirds vote of both houses to place on the ballot, and then a majority of voters must approve them. The governor plays no formal role.12California Department of General Services. SAM 6920 – Constitutional Amendments
- Resolutions, which state the Legislature’s opinion or intent and don’t carry the force of law.
The Budget’s Own Track
The annual state budget follows a separate timeline. The governor submits a proposed budget in January, and the constitution requires the Legislature to pass a budget bill by June 15.13California Department of Finance. California’s Budget Process Miss that deadline and legislators forfeit their salary and per diem for every late day, a consequence added by Proposition 25 in 2010.
Proposition 25 also lowered the vote threshold for the budget itself. Before 2010, passing a budget required a two-thirds supermajority in both houses, which regularly produced gridlock and months-long delays. Now the budget passes with a simple majority. Tax increases, however, still require a two-thirds vote of each chamber, a distinction that matters enormously during fiscal negotiations.
Gift and Lobbying Limits
California caps what legislators can accept from registered lobbyists at $10 per calendar month in gifts.14California Fair Political Practices Commission. Gifts, Honoraria, Travel Payments, and Loans The limit is far lower than what many other states allow, and it covers anything of value: meals, tickets, travel.
After leaving office, former legislators face a one-year cooling-off period during which they cannot lobby the Legislature for pay. A member who resigns mid-session faces a longer restriction: the ban runs from the resignation date through one year after that session’s final adjournment.15California Legislative Information.

How You Can Weigh In
You don’t need to be a lobbyist or insider to engage with the process. The most direct methods are contacting your legislator’s district office, writing a letter about a specific bill, or attending a committee hearing in person to testify.16California State Senate. Legislative Process Booklet All committee hearings are open to the public.
If you plan to testify, prepare your remarks in advance, stay brief and specific, and notify the bill’s author that you intend to speak. Some hearings allow remote participation by phone. You can also submit written position letters to the relevant committee, which become part of the public record on that bill. Timing matters. A letter that arrives after the committee vote has little impact, so tracking the legislative calendar is worth the effort.
