Castro Valley, CA
Castro Valley is the largest unincorporated community in Alameda County — bigger than most of the county's actual cities — and it is policed directly by the Sheriff's Office out of the Eden Township Substation.
Castro Valley is an unincorporated community, not an incorporated city — it doesn't have its own city government or police department. Law enforcement here is provided directly by the Alameda County Sheriff's Office's Eden Township Substation, the same as neighboring Sunol and other unincorporated pockets of the county.

Castro Valley, CA
Castro Valley is an unincorporated community, not an incorporated city — it doesn't have its own city government or police department. Law enforcement here is provided directly by the Alameda County Sheriff's Office's Eden Township Substation, the same as neighboring Sunol and other unincorporated pockets of the county.
Castro Valley's 2020 Census population of 66,441 makes it the fourth most populous unincorporated area in the entire state of California. It is larger than ten of the fourteen incorporated Alameda County cities built out on this site, and it still has no city council, no city hall and no police department of its own.
That matters for a bail case in a very practical way. There is no city department to call and no city holding facility in the timeline. A Castro Valley arrest is an Alameda County Sheriff's Office arrest from the first minute, and the booking record moves into the county jail system — anchored by Santa Rita Jail at 5325 Broder Boulevard in Dublin, (925) 551-6500 — without the city-to-county transfer step that delays county custody searches in Oakland, Hayward or Fremont.
The community takes its name from Guillermo Castro, the nineteenth-century Californio ranchero whose Rancho San Lorenzo covered this land before it was subdivided.
Which courthouse hears a Castro Valley case is not confirmed. The Hayward Hall of Justice at 24405 Amador Street is the nearest Superior Court location by a wide margin and is the reasonable candidate, but Alameda County Superior Court publishes no assignment naming Castro Valley or any other unincorporated community. We will not print a guess — the notice to appear names the right building.

Arrest & Booking — What Happens First
Every Castro Valley arrest follows the same path. Here is each step, with the real contact at each one.
Find An InmateArrest and transport
An arrest in Castro Valley is made by Sheriff's deputies working out of the Eden Township Substation. There is no city police department step, because Castro Valley has no city government — the case is in the county system from the first minute.
Transfer into county custody
Anyone not cited and released moves into the Alameda County Sheriff's Office jail system, anchored by Santa Rita Jail, 5325 Broder Boulevard, Dublin, (925) 551-6500. We confirm the exact housing location by phone rather than assuming it.
Bail is set
Once booking is complete, bail is usually set from the countywide bail schedule adopted under Penal Code §1269b. A judge can raise, lower, or eliminate it at arraignment.
Posting the bond
We post directly with the facility holding your loved one. Premiums are regulated under Insurance Code §1800 and run 10% of the bail amount, with as low as 1% down for qualifying cosigners.

Eden Township Substation — Alameda County Sheriff's Office

ACSO's own facility directory lists the Eden Township Substation at 15001 Foothill Boulevard, San Leandro, CA 94578, (510) 667-7721, and Alameda County's building directory shows the same address. The 2000 150th Avenue address that circulates elsewhere does not appear on any official county page we could find. ACSO's directory does separately list a Castro Valley Marketplace location at 3295 Castro Valley Boulevard with no phone number, which suggests the substation may be backed by smaller offices — we have not been able to confirm what that location is, so call the substation number before driving anywhere.

Alameda County Superior CourtBail Amounts In Castro Valley — And What It Costs You
Bail set at booking follows Alameda County's uniform bail schedule adopted under Penal Code §1269b, so amounts in Castro Valley match the countywide figures — there is no separate Castro Valley schedule. Premiums are regulated under Insurance Code §1800 and typically run 10% of the bail amount.
Bail Payment Breakdown
| Total Bail Amount | 10% Premium (Total Cost) | 1% Down (To Start) |
|---|---|---|
| $5,000 | $500 | $50 |
| $10,000 | $1,000 | $100 |
| $25,000 | $2,500 | $250 |
| $50,000 | $5,000 | $500 |
| $100,000 | $10,000 | $1,000 |
Examples only. The 1% tier requires approved credit and a qualifying cosigner.
How The Math Works
Bail is set at $25,000. California's regulated premium is 10%, so your cost is $2,500. The Bail Network posts the full $25,000 with the court. The premium is earned and non-refundable once the bond is posted — that is California Insurance Code §1800, not our policy. Qualifying families can arrange payment plans starting as low as 1% down.
What Bail Costs By Charge Level
Legal Authority
Bail schedules are set by the Alameda County Superior Court judges in accordance with California Penal Code §1269b. Specific amounts may vary based on prior convictions and special circumstances.
Payment Plans — How Families Actually Pay
The premium is regulated, but how you pay it is not one-size-fits-all. Qualifying families can start as low as 1% down and pay the balance on a written schedule.
Payment Plans
Flexible schedules on the premium itself — ask about monthly arrangements built around what you actually earn.
Collateral Options
Many bonds, especially lower-tier misdemeanors and first-offense DUIs, do not require collateral at all.
Multiple Payment Methods
Visa, Mastercard, American Express, ACH bank transfer, Zelle, and cash.
The 10% premium is non-refundable once the bond is posted, regardless of the case outcome — that is California law (Insurance Code §1800), not Bail Network policy.
Qualifications
Who Qualifies — Bail Denial And Down-Payment Tiers
Misdemeanor Arrests — Almost Always Bailable
The county bail schedule adopted under Penal Code §1269b applies, so no judge is required for most cases. Release is often same-day once bail is set and the bond is posted.
Felony Arrests — Usually Bailable
Bail is commonly set at arraignment, and Penal Code §1270.1 requires a formal hearing before release on certain serious or violent felonies.
Bail-Denial Cases — Bail May Be Denied
Under Article I, §12 of the California Constitution, bail can be denied for capital offenses and for violent or sexual-assault felonies where the evidence is strong. In re Humphrey (2021) requires courts to weigh ability to pay before setting an unaffordable amount.
Domestic Violence — Protective Orders Apply
An Emergency Protective Order is often issued at arrest, with a longer Criminal Protective Order possible at arraignment. No-contact conditions typically apply on release — read them carefully before going home.
When Bail Can Be Denied
Under Article I, §12 of the California Constitution, bail can be denied for capital offenses, and for felonies involving acts of violence or sexual assault on another person, when the facts are evident and the presumption of guilt is great.
In In re Humphrey (2021), the California Supreme Court held that a court cannot set bail an arrestee is unable to afford without first considering their ability to pay and less restrictive alternatives. That argument is made at the bail hearing itself.
Payment Options
Down-Payment Tiers
1% is the lowest down payment we offer, but 5% is generally the sweet spot for bail bond payments.
- 1%1% downLowest Down
Strongest cosigner profile — good credit, long employment, homeowner or verifiable equity.
- 3%3% down

- 5%5% downSweet Spot
Mixed credit or shorter work history, still with a qualifying cosigner.
- 10%10% down
No cosigner, thin credit, prior failure-to-appear history, or a high-exposure charge.

Castro Valley FAQs
Is Castro Valley a city?
No. Castro Valley is an unincorporated community — a census-designated place — with no city government and no police department, even though its 66,441 residents make it larger than most Alameda County cities. The Sheriff's Office polices it directly from the Eden Township Substation.
Where does someone arrested in Castro Valley get booked?
Into the Alameda County Sheriff's jail system, anchored by Santa Rita Jail at 5325 Broder Boulevard, Dublin, (925) 551-6500. Because the arresting agency is already the Sheriff's Office, the county record typically appears sooner than it would after a city-police arrest.
Which courthouse hears a Castro Valley case?
Not confirmed. The Hayward Hall of Justice, 24405 Amador Street, is the closest Superior Court location and the reasonable candidate on geography, but the court publishes no assignment naming Castro Valley.
