California term limits cap state legislators at 12 total years of service across both chambers, limit the governor and other statewide constitutional officers to two four-year terms each in the same office, and leave local offices and congressional seats to separate rules. The restrictions sit in the California Constitution, mostly placed there by Proposition 140 in 1990 and revised for the Legislature by Proposition 28 in 2012.
The 12-Year Legislative Cap
Anyone first elected to the California Legislature after June 5, 2012, can serve a maximum of 12 years, whether that time is spent entirely in the Assembly, entirely in the Senate, or split between the two.1California State Legislature. Constitution of the State of California Article IV Legislative The authority is Article IV, Section 2 of the state constitution, as amended by Proposition 28.
In practice, that allows six two-year Assembly terms, three four-year Senate terms, or any mix that adds up to 12 years. The clock follows the person, not the seat, so moving to a different district and running again does not reset it. Once a member hits 12 years, they are permanently barred from both chambers.
Proposition 28 replaced an older system under Proposition 140 that capped Assembly service at six years and Senate service at eight, for a combined maximum of 14. Legislators already serving when Proposition 28 took effect in June 2012 remain under those older chamber-by-chamber limits.1California State Legislature. Constitution of the State of California Article IV Legislative That grandfathered group has largely cycled out, but the distinction still matters for any eligibility question involving a longtime officeholder.
Governor: Two Four-Year Terms
The governor is limited to two four-year terms. Article V, Section 2 of the state constitution puts it bluntly: “No Governor may serve more than 2 terms.”2Justia. California Constitution Article V Section 2 – Executive Proposition 140 added that limit in 1990, and it has not changed since. After eight years, a former governor cannot hold the office again, though nothing in the rule prevents a run for a different statewide seat.
Other Statewide Constitutional Officers
California’s other top elected executives are each capped at two four-year terms in the same office, though the limits are scattered across several constitutional provisions.
Article V, Section 11 covers five offices together: Lieutenant Governor, Attorney General, Controller, Secretary of State, and Treasurer. Each is elected for a four-year term alongside the governor, and none may serve more than two terms in the same office.3Justia. California Constitution Article V Section 11 – Executive
The Superintendent of Public Instruction is governed separately under Article IX, Section 2, which imposes the same two-term cap.4Justia. California Constitution Article IX Section 2 – Education Elected members of the Board of Equalization are limited to two four-year terms under Article XIII, Section 17.5Justia. California Constitution Article XIII Section 17 – Taxation The Insurance Commissioner, made an elected post by Proposition 103 in 1988, is limited to two terms under the California Insurance Code rather than the constitution.
Because each cap attaches to a specific office, finishing two terms in one role does not shut someone out of another. A termed-out Attorney General can still run for governor, serve eight years, and move on to another statewide seat. The two-term rule prevents long tenure in a single office; it does not prevent a long career spread across several of them.
How Partial Terms and Appointments Count
Whether a mid-term appointment or special-election win eats into someone’s limit depends on which rules apply.
Under the old Proposition 140 structure for the Legislature, serving less than half of another person’s remaining term did not count as one of a member’s allotted terms.6Legislative Analyst’s Office. Proposition 28 – Limits on Legislators Terms in Office A short appointment to finish a few months of a vacant seat would not cost a newcomer one of their three Assembly terms or two Senate terms.
Under Proposition 28’s 12-year lifetime cap, the arithmetic shifted because the limit is measured in years of total service rather than discrete terms. Every year counts toward the 12-year ceiling, so an appointment that covers two years of a predecessor’s Assembly term uses two of the member’s 12 years.
For statewide constitutional officers, the constitution says only that no person may serve more than two terms in a given office. Whether a short partial term counts as one of those two can turn into a factual question for election officials or the courts based on the specific circumstances.
Local Offices Set Their Own Rules
The state constitution does not set term limits for city councils, mayors, or county boards of supervisors. California Government Code Section 36502 lets city councils and city voters adopt or repeal term limits for council members and elected mayors, with any proposal going before voters at a regularly scheduled election and taking effect only on majority approval.7California Legislative Information. California Code GOV 36502 The statute also requires that any new limit apply only going forward, so sitting council members are not forced out retroactively.
Counties have a parallel mechanism that allows voters to impose limits on boards of supervisors. The results vary widely across the state: some cities and counties cap elected officials at two consecutive terms, others at three, and others impose no limits at all. Charter cities can also write term-limit provisions directly into their charters, which can differ from what the Government Code prescribes for general-law cities. To find the rule for a specific local office, check the city or county charter and any local ordinance adopted by the voters.
Congressional Seats Are Off Limits for State Rules
California cannot impose term limits on its members of the U.S. House or Senate. The U.S. Supreme Court decided in U.S. Term Limits, Inc. v. Thornton (1995) that states lack the power to add qualifications for congressional candidates beyond the age, citizenship, and residency the U.S. Constitution already requires.8Cornell Law. U.S. Term Limits Inc. v. Thornton, 514 U.S. 779 Any federal term limit would require a constitutional amendment.
