13 Of 14 Cities Run Their Own Police Department
Only Dublin Contracts With The Sheriff
Alameda County works differently from every other county in this network. Only one city — Dublin — contracts with the Alameda County Sheriff's Office (ACSO) for its policing. The other 13 incorporated cities, including Oakland, Berkeley, Fremont, Hayward and San Leandro, all run their own independent police departments. ACSO directly patrols only the unincorporated areas of the county and Dublin — plus, under separate contractual agreements, Oakland International Airport, Highland Hospital, county Social Services facilities, and the Alameda-Contra Costa Transit District (AC Transit).
Alameda County Sheriff's OfficeFounded 1853 — And It Trains The Independents Too
Founded in 1853, ACSO also runs a regional police academy used not just by its own recruits but by officers from Hayward PD, San Leandro PD, Alameda PD and other Bay Area departments — meaning even the independent departments in this county have real, ongoing ties to the Sheriff's Office beyond policing itself.
Why this matters for a bail search: an arrest almost anywhere in Alameda County — 13 of 14 cities — starts with that city's own independent department, not ACSO. Dublin is the one real exception, and unincorporated areas of the county are the other place ACSO handles policing directly from the start.
One Major County Jail: Santa Rita
ACSO Runs The County Jail System
ACSO operates the county jail system, anchored by Santa Rita Jail, 5325 Broder Boulevard, Dublin, CA 94568, (925) 551-6500 — one of the largest county jail facilities in California, confirmed against ACSO's own facility directory. The current Sheriff, Yesenia Sanchez, elected in 2022, is the first woman to hold the office in the county's history, unseating a longtime incumbent in a closely-watched local race.
ACSO's administrative office is at 1401 Lakeside Drive, 12th Floor, Oakland, CA 94612, (510) 272-6878. Deputies also patrol the unincorporated county directly out of the Eden Township Substation, 15001 Foothill Boulevard, San Leandro, (510) 667-7721, which covers Castro Valley, San Lorenzo, Ashland, Cherryland, Fairview and Sunol. County listings are not consistent about that street address — a second Castro Valley Boulevard location also appears in county directories — so treat the phone number as the reliable contact and confirm the counter address with ACSO before driving out.
Any secondary county facilities are deliberately not asserted here. They will be confirmed against ACSO's own site and built as their own pages — the same standard held for every prior county hub in this directory.

Already Live: The Alameda County Inmate Locator
We already run a dedicated Alameda County Inmate Locator page with a real local listing in Dublin. It covers searching for someone in county custody step by step; this hub covers the county as a whole — who polices which city, how the jail system is organized, and what a bond actually costs.
If the person you are looking for was arrested by a city department, the county search may lag behind the arrest by hours. Call (213) 510-2764 with a name and date of birth and an agent confirms the exact location before you travel anywhere.
Alameda County Cities We Serve
We post bonds for arrests made anywhere in Alameda County. Cities are grouped by who actually polices them, because that determines where a search starts. Alameda County's unincorporated communities are listed too — Castro Valley, San Lorenzo, Ashland, Cherryland and Fairview each have their own page and are policed directly by the Sheriff, and Sunol is covered by the same Eden Township Substation. Call any time and an agent handles the search directly.

Alameda County Superior CourtAll 10 Alameda County Courthouses
Every Alameda County Superior Court location now has its own page, confirmed against the court's own official site: three separate buildings in Oakland, plus Alameda, Berkeley, Dublin, Fremont, Hayward, and two specialized venues in San Leandro.
Where the court does not confirm which city goes where, we say so rather than guess. The courthouse named on the notice to appear is always the authoritative answer, and an agent will confirm it with you.
Bail Schedule & Cost
Alameda County adopts its own bail schedule, set independently from every other California county, so the same charge can carry a different preset amount here than in Los Angeles, Orange or San Diego County.
How Bail Is Set
Under Penal Code §1269b, each county adopts a bail schedule — a preset bail amount by charge — that applies at booking. A judge can raise or lower that amount, or release the defendant on their own recognizance, at a court hearing.
Read PC §1269bBail Hearings
Penal Code §1270.1 requires a formal hearing before bail can be increased or reduced on certain serious or violent felony charges. That hearing window is when having a bondsman ready matters most — the bond can be posted the moment bail is set.
Read PC §1270.1What A Bond Costs
Bail bond premiums in California are regulated under Insurance Code §1800 and typically run 10% of the face amount of the bond. Qualified cosigners can start with as low as 1% down on a written payment plan.
Read Ins. Code §1800Typical Alameda County Bail Bond Cost
| Bail Amount | Typical 10% Premium | Payment Plan Available |
|---|---|---|
| $1,500 | $150 | Yes, with an approved cosigner |
| $5,000 | $500 | Yes, with an approved cosigner |
| $10,000 | $1,000 | Yes, with an approved cosigner |
| $25,000 | $2,500 | Yes, with an approved cosigner |
| $50,000 | $5,000 | Yes, with an approved cosigner |
| $100,000 | $10,000 | Yes, with an approved cosigner |
Examples only. The exact premium and down payment depend on the charge, the court, and cosigner qualification. Call (213) 510-2764 for an exact quote before anything is signed.

Does my city have its own police department, or does it contract with the Sheriff?
In Alameda County the answer is almost always the city's own department. Thirteen of the fourteen incorporated cities — Oakland, Berkeley, Fremont, Hayward, San Leandro, Alameda, Union City, Newark, Pleasanton, Livermore, Piedmont, Albany and Emeryville — run independent police departments. Dublin is the single exception: it contracts its policing to the Alameda County Sheriff's Office. ACSO also polices the unincorporated areas of the county directly, and under separate agreements covers Oakland International Airport, Highland Hospital, county Social Services facilities and AC Transit.
Why did my loved one's search come back empty right after the arrest?
Booking takes time. With 13 independent departments making most of the arrests in this county, someone can sit in a city department's own holding area before any transfer into the Sheriff's jail system — which means a county search returns nothing yet. If the search is empty, wait and search again rather than assuming the arrest did not happen, or call and an agent will run it directly.
Which courthouse will my case be heard at?
Alameda County Superior Court is a consolidated countywide trial court, and ACSO provides security to those courts directly. We are not naming individual courthouse jurisdictions on this page until each one is confirmed against the court's own official source — this project has been burned before by secondary sites that were wrong on exactly this. Go by the courthouse named on the notice to appear, and call us if the paperwork is unclear.
How much does an Alameda County bail bond cost?
California bail premiums are regulated under Insurance Code §1800 and typically run 10% of the face amount of the bond. Qualifying cosigners can start with as low as 1% down on a written payment plan.
My city isn't listed yet — can you still help?
Yes. Individual city pages are being published in stages, but coverage is countywide today. Call and an agent handles the search and posts the bond at whichever Alameda County facility your loved one is being held in.
