The Santa Clara County Board of Supervisors is the five-member elected body that governs Santa Clara County, California. It sets policy for a jurisdiction of nearly two million residents, passes local ordinances, and adopts an annual budget that exceeds $13 billion, while an appointed County Executive handles day-to-day operations.
Who Sits on the Board
California law requires every county board of supervisors to have five members, and no more than three can be elected at the same general election. Terms run four years and are staggered, so the Board never turns over all at once.1California Legislative Information. California Code Government Code 25000 – Organization Each Santa Clara supervisor is elected by the voters of one geographic district, with the five districts stretching from San Jose to the rural southern end of the county near Gilroy.
Santa Clara is a charter county, meaning its own charter (adopted at a special election on April 20, 1965) governs how local offices are organized.2Santa Clara County Registrar of Voters. Election Results Archive 1960-1969 That charter gives the county more control over its internal structure than a general law county has.
Term Limits
The charter caps service at three successive four-year terms. After reaching that twelve-year limit, at least four years must pass before the same person can serve again by election or appointment.3County of Santa Clara. Charter of the County of Santa Clara Two anti-circumvention rules back this up: anyone appointed to fill a vacancy for more than two years of a term is treated as having served a full term, and a supervisor who resigns with fewer than two years left is also counted as having completed the term.
Residency
Candidates must be registered voters living in the district they want to represent and must have resided there before nomination or appointment. The charter ties the required residency duration to state law rather than setting its own timeline. Once elected, a supervisor who stops living in the district loses the seat.3County of Santa Clara.

District boundaries are redrawn after each federal census. An Advisory Redistricting Commission appointed by the Board holds public hearings and recommends new maps, which the Board then approves. The lines must satisfy California’s FAIR MAPS Act and the federal Voting Rights Act, with attention to geographic contiguity, compactness, and keeping recognized communities together.4County of Santa Clara.

What the Board Does
Adopting the Budget
Approving the annual county budget is the Board’s most consequential job. For fiscal year 2025–26, the adopted budget anticipated $12.6 billion in revenues and $13.0 billion in net expenditures, funding everything from the county health system to law enforcement to road maintenance.5County of Santa Clara.

Passing Ordinances
The Board enacts local ordinances covering land use, public health, and safety standards for unincorporated areas and, in some cases, countywide. Those ordinances follow the enacting format set by California Government Code Section 25120.7California Legislative Information. California Code Government Code 25120 – Ordinances
Overseeing County Departments
The Board sets policy direction for a wide network of county departments, including the Social Services Agency and the county health system, and controls their budgets. Independently elected officials such as the Sheriff and District Attorney run their own offices, but their funding still passes through the Board’s appropriation process, which gives supervisors significant leverage over resources even where they lack direct operational control.
How the Board Differs From the County Executive
The Board does not run county operations itself. That work belongs to the County Executive, an appointed chief administrative officer the Board hires based on administrative qualifications and may remove at any time.3County of Santa Clara. Charter of the County of Santa Clara
The County Executive appoints, supervises, and removes department heads for all non-elected offices; prepares the annual budget for the Board’s review; coordinates across all departments; and manages county property. Each fiscal year the Executive must deliver a proposed budget with an explanatory message by June 30 and submit a year-end report on finances and administrative performance. The result is a split closer to a council-and-manager city than to a traditional county: the Board makes policy and holds the purse, and the Executive runs the organization.
How Board Meetings Work
Board meetings are governed by the Ralph M. Brown Act, California’s open-meeting law at Government Code Sections 54950 through 54963. Almost all county business must be conducted in public view.
A regular meeting agenda has to be posted at least 72 hours in advance, with a brief description of every item, the meeting time and location, and placement both at a publicly accessible physical location and on the county’s website.8California Legislative Information. California Government Code 54954.2 Special meetings for urgent business require 24 hours’ notice. Items not described on the agenda generally cannot be acted upon.
Three supervisors make a quorum, but a quorum alone is not enough to pass anything. No action is valid unless a majority of all five members votes yes, so at least three affirmative votes are required regardless of how many supervisors are present.9California Legislative Information. California Code Government Code 25005 The Clerk of the Board records all votes and keeps the official minutes.
The Board can meet in closed session only for a narrow set of statutory topics. The most common are real estate negotiations involving county property, discussions with legal counsel about pending or anticipated litigation, and settlement talks in active lawsuits. The Board must publicly announce the general topic before going into closed session and report certain outcomes afterward. Everything else happens in open session.
How To Participate
You can address the Board in person at scheduled meetings. For items already on the agenda, sign up to speak before that item is called, either with a speaker card or by registering electronically. Each speaker gets a set amount of time, which the presiding supervisor may shorten when many people want to be heard on the same item.
A separate general public comment period, usually near the start of the meeting, is reserved for topics within the county’s jurisdiction that are not on the agenda. The Board cannot take action on anything raised during this period because it was not noticed, but supervisors can ask staff to look into the matter or place it on a future agenda.10County of Santa Clara.

Written comments are another option. Letters, emails, and supporting documents submitted to the Clerk of the Board become part of the official record for the relevant agenda item and are preserved as a permanent record of public input on every decision the Board makes.
