Alameda County offices and records

Sheriff & Law Enforcement. Alameda County Sheriff's Office is responsible for law enforcement services in the unincorporated areas of Alameda County, as well as operating Alameda County jail system.

Police Departments. Alameda County is served by several law enforcement agencies, including Alameda County Sheriff's Office and municipal police departments such as the Oakland Police Department, Berkeley Police Department, and Fremont Police Department. Each city department is responsible for law enforcement within its jurisdiction, while the Sheriff's Office provides support and coordination for major crimes and county-wide initiatives.

Law Enforcement & Arrests. Alameda County Sheriff's Office lists its Administrative Office at 1401 Lakeside Drive, twelfth floor, Oakland, CA 94612 and phone 510-272-6878 in the facility directory. The office provides services in unincorporated areas and contract jurisdictions. The existing Sheriff's Office link remains available for agency information. Santa Rita Jail lists 5325 Broder Boulevard, Dublin, CA 94568 and 925-551-6500. Arrest and investigative-record access depends on the record and applicable disclosure rules; consult the California Public Records Act guidance rather than treating all arrest records as publicly available personnel records.

Criminal Records. The Superior Court records instructions distinguish public case information, document-copy requests and courthouse access for nonconfidential criminal files.

Arrest Records. They are maintained by the arresting agency, primarily the County Sheriff's Office and municipal police departments.

Is an old working under a property here?

The mine records hold 215 mine sites inside the county: 66 past producers, now closed, 68 prospects or occurrences that were never worked, 74 sites producing when the record was made, 3 processing plants, which are not workings, 4 sites with no status in the record; the old survey maps add 62 holes drawn inside the county, 11 of them shafts or tunnels. The minerals the records name are construction sand and gravel; Manganese; Stone.

A point in either file is a location, not a property line: the sheet shows the opening on the surface, not the rooms under it. The record that shows what runs under a parcel is the mine map. The OSMRE National Mine Map Repository holds scanned underground mine maps and answers requests for a named mine or an area.

Alameda County records across counters and online systems

Separate court, recorder and city functions

Alameda County public records are distributed among the Superior Court, county departments and incorporated cities. The Clerk-Recorder handles recorded property instruments and specified vital records. The Superior Court maintains court files. A city planning department can hold permits for property within that city even though the county recorder holds the deed. Begin with the record's purpose and location instead of assuming a countywide portal contains every document.

Public court information and document access

The Superior Court records instructions distinguish remote case information from document access. The criminal Odyssey search covers cases with activity since 2005 and does not give the general public remote access to the documents themselves. The court separately describes in-person criminal information for many cases opened since 1974. These are different coverage statements, not interchangeable online start dates.

Use the case number to request the order, complaint or other particular filing. The court offers a separate criminal-copy request process and requires identifying information for the defendant and case. For civil, family and probate matters, follow the appropriate division's instructions. A portal result can help identify a file without establishing eligibility to view confidential material. Before traveling, confirm which records unit holds the case; county court work is distributed across several locations.

An immigration letter requiring a signature and court seal has a specific mail process in the court's instructions. Do not order an ordinary portal copy and assume it meets that requirement. State the receiving agency's requirements when asking the court to identify the correct product.

Land indexes and document references

The recorder's research instructions place records before 1969 on microfilm for manual searching at the office, while records from 1969 onward are in electronic format for online searching. Save the instrument number, book and page, or reel and image reference from the index. Those identifiers allow a copy request to target a specific document rather than an entire owner history.

An index is a finding tool. The image or certified copy provides the actual terms, legal description and recording endorsement. A name search can miss a document indexed under a former name, entity name or different spelling. Review related instruments when the chain of title refers to a prior deed, release or reservation. Ask the office about the correct copy and certification charge before ordering a long instrument.

The recording rules distinguish page size, document titles and additional charges. A recording payment is the charge to place a new instrument in the public record, not the price to obtain a copy of an existing deed. Identify exemptions and the document class before treating a posted base amount as the total.

Current certificate prices and office choice

The Clerk-Recorder fee notice effective January 1, 2026 lists certified birth copies at $36, death copies at $28 and marriage copies at $21. These are county certificate prices; ordering-channel and payment charges can be additional. Determine whether an authorized certified copy or an informational copy is appropriate, and supply the application and identity documents required for that product.

The office directions list the Oakland full-service location at 1106 Madison Street and the Dublin satellite at 7600 Dublin Boulevard, Suite 160. The satellite provides selected services and does not accept mailed requests. Confirm the service location before visiting or mailing a payment, especially when the request combines research with a certificate order.

Assessed value, tax bills and permits

The Assessor's contact directory separates real-property and business-personal-property assistance. Use the parcel identifier and tax year when asking about an assessment. The property-tax service handles bill and payment information. A tax-account display does not replace a recorded deed, and an assessment value is not a promise of market sale price.

For unincorporated property, the Planning Department separates its main office from the zoning desk at the permit center. Ask about the parcel's jurisdiction before requesting a permit history or land-use decision. Incorporated cities maintain their own local planning files. A permit record concerns authorization and inspections for work; it does not settle ownership.

Jail and arrest-related requests

The sheriff's Santa Rita Jail directory entry gives 5325 Broder Boulevard, Dublin, California 94568 and 925-551-6500. Use current custody tools for detention information and the arresting agency for its report. A jail booking does not establish a conviction. To determine a charge's outcome, follow the corresponding court case and final disposition.

The Sheriff's facility directory distinguishes administration, patrol, civil service and jail locations. Describe the incident or service requested before choosing a counter. Report access can depend on the record and applicable disclosure rules; a statement that a booking occurred does not make every investigative document public.

Administrative records and personal history

California's Public Records Act guidance describes an initial determination within 10 calendar days, with a qualifying extension of up to 14 days. That determination period is not a universal production deadline. Identify the department, existing records, date range and preferred format, and ask about copying or extraction costs before accepting a large order.

A statewide personal criminal-history review is a different request. The Department of Justice record-review procedure uses fingerprints and lists a $25 processing fee, with fingerprint collection charges separate. A local court search, a sheriff report and a DOJ personal review have different purposes and coverage.

Keep each result tied to its source

For every result, save the office, file number, record date, search date and whether it is an index, uncertified image or certified document. Keep a written account of any date limits or access restrictions. Use the California records guide when the record belongs to a state agency or another county.

Alameda County public-records FAQs

Open only the answer you need.

Where can I find mugshots or booking photos in Alameda County, California?

How do I get a criminal background check in Alameda County, California?

The California criminal history record comes from the California Department of Justice.

By mail with form VS 111 to California Department of Public Health, Vital Records, MS 5103, P.O. Box 997410, Sacramento, CA 95899-7410, or in person at the county office where the event was registered; since July 1, 2026 CDPH VR no longer accepts applications sent through online third party vendors.

How do I find business license records in Alameda County, California?

Business entity filings are searched with the California Secretary of State (bizfile Online). Most California cities and counties require a business license, permits or registration to do business within their limits.

Does Alameda's online criminal portal provide the document images?

The court's public-access instructions distinguish online criminal case information from the documents. The general public can use the separate copy-request process or the available courthouse access route for nonconfidential documents.

How far back does Alameda's electronic land-record search extend?

The recorder's research page identifies 1969 as the start of electronic-format records. Earlier records require manual microfilm research at the office. Keep the instrument or reel reference when ordering copies.

Can I mail my certificate request to the Dublin satellite?

No. The jail listing places Santa Rita at 5325 Broder Boulevard in Dublin and gives 925-551-6500. Administration and custody services have different locations and responsibilities.

Will an assessment record prove who owns a parcel?

It is a tax-administration record. Use the Assessor for assessment questions and request the recorded instrument when investigating a conveyance. Compare names, parcel identifiers and legal descriptions instead of relying on an address alone.

Who has planning records for unincorporated Alameda County?

The county Planning Department is the starting point for its land-use files. Confirm whether the parcel is in county jurisdiction or an incorporated city before requesting a permit history.

Is a DOJ record-review fee the price for a local court search?

No. The DOJ personal-review service lists $25 for its fingerprint-based processing, excluding fingerprint collection. Court copies and local police records use their own custodians and charges.
