What Are Contra Costa Arrest Records?
Contra Costa arrest records are summaries of incidents where individuals are taken into custody. An arrest happens when law enforcement believes a person committed a crime, based on probable cause. After an arrest, the person is typically booked at a detention facility, like the Martinez Detention Facility, or a local police station. This booking event creates the arrest record.
These records list alleged offenses, personal details of the arrested person, and information about their detainment. Prosecutors use these records to decide on charges. They also serve as public files to track criminal behaviors and support court cases.
Public Access to Contra Costa Arrest Records

However, certain details in arrest records are not available to the public. These restrictions protect sensitive information and ongoing investigations.

Contra Costa County Arrest Warrants
A Contra Costa County arrest warrant is a legal order from a judge or magistrate that allows a peace officer to arrest a named person. Law enforcement must have “probable cause” to obtain a warrant, meaning there must be enough evidence to convince the court that a person likely committed a crime. This evidence is usually provided through an affidavit filed with a criminal complaint.
Warrants include the suspect’s name, the alleged offense, the date and place of issuance, the judge’s signature, the issuing court, the executing officer or agency, and any bail amount. Arrest warrants typically allow officers to arrest at any time, day or night. Misdemeanor warrants, however, are usually executed between 6:00 a.m. and 10:00 p.m., unless the warrant states otherwise.
How to Search for Contra Costa County Arrest Warrants
Individuals looking for active arrest warrants in Contra Costa County can use several official methods. It is crucial to use official sources to ensure accuracy.
- Contra Costa County Superior Court Website: The court’s online portal allows searches for court records, which may include warrant information. Users can search by name or record number without needing a login. Instructional guides are available for new users. For direct inquiries, the Superior Court can be contacted at (925) 608-1000.
- Contra Costa County Sheriff’s Office: The Sheriff’s Office Records Unit accepts walk-in requests for existing arrest warrants. Visitors to the local police station will likely need to show a photo ID. The Sheriff’s Office also maintains records of all warrants issued within its jurisdiction and enters this information into state and national databases. While the Sheriff’s Office offers an online portal for warrant lookups, it may not include all outstanding warrants, especially those recently issued. For a complete search, direct contact with the Sheriff’s Department is advised.
- In-Person or Phone Inquiries: Visiting the Contra Costa County Sheriff’s Office or the Superior Court in person remains a reliable method. The Sheriff’s Office is located at 651 Pine Street, 7th Floor, Martinez, CA 94553, and can be reached at (925) 335-1500. The Wakefield Taylor Courthouse of the Superior Court is at 725 Court Street, Martinez, CA 94553, phone (925) 608-1000. Public access terminals are also available at courthouses.
Do Contra Costa County Arrest Warrants Expire?
No, Contra Costa County arrest warrants do not expire automatically. They remain active until the arresting officer executes the order by apprehending the named person. Bench warrants and arrest warrants stay in effect until the person is arrested, appears in court as required, or the court officially withdraws the warrant. Search warrants, in contrast, have a strict 10-day execution window before they expire, unless a court grants an extension. If an individual discovers an outstanding warrant, it is important to confirm the information with official sources like the Sheriff’s Records & ID Unit or the Superior Court Clerk’s Office. The next steps depend on the warrant type, and consulting a legal professional is often advised for a swift resolution.
Contra Costa County Arrest Records Versus Criminal Records
The terms “arrest record” and “criminal record” both relate to a person’s involvement with the justice system, but they carry different meanings and implications.
- Arrest Record: This is a summary of an individual’s arrest incidents. It includes details about the circumstances and results of one or more arrests. An arrest record does not mean the person was convicted of the crime.
- Criminal Record (RAP Sheet): This provides a more complete look at a person’s interactions with the criminal justice system. It includes arrests, warrants, convictions, sentences, probation, and other dispositions. A criminal record has greater implications for future activities such as licensing, bank loans, employment, housing, and school admission.
Obtaining Contra Costa County Criminal Records
Individuals can request their own criminal history information to check for accuracy.
- Local Record Review: To get a copy of a Contra Costa County criminal record, a person can apply for a local record review. This can be done in person or by mail to the local sheriff’s Records Unit at 2530 Arnold Drive, Suite 170, Martinez, CA 94553. The office phone number is (925) 335-1570. Records personnel provide information on police reports, out-of-custody inmate inquiries, and clearance letters. A fee of $25 applies, payable by cash (exact change) or check. Fingerprint submission may be required for proper identification. California Penal Code Sections 13320-13323 allow individuals to request a summary list of their own arrests from local law enforcement agencies. Requests for other individuals’ summary arrest information are not processed.
- Statewide Criminal Background Check: People with criminal records in other California counties can request a statewide criminal background check from the California Department of Justice (DOJ). This costs $25. Applicants need to submit fingerprints and a Live Scan Form through a Live Scan operator, who typically charges a fee for the service. The DOJ’s “Request Your Own Criminal Record” page provides detailed information and steps for ordering criminal record checks. The DOJ does not provide certified copies of criminal history records to individuals. Access to criminal history summary records is restricted to law enforcement and authorized agencies, but individuals can request their own for review.
- Federal Criminal Records: Federal arrestees can submit a record check request to the Federal Bureau of Investigation (FBI) for $18.
How Long Do Arrests Stay on Your Record?
An arrest history remains a permanent part of a person’s criminal record unless a court orders it sealed or expunged. Even if a person is not convicted, the arrest event itself is recorded. Criminal justice agencies use retention schedules to store arrest records. The California Department of Justice, for example, maintains records until the person reaches 100 years of age.
Sealing and Expunging Contra Costa Arrest Records
Sealing or expunging an arrest record can remove it from public view. This process allows eligible individuals to petition the court for removal.
Expungement Process
To expunge Contra Costa County arrest records, eligible individuals must file Form CR-409, a Petition to Seal Arrest and Related Records, with the Contra Costa County Superior Court. Under California Penal Code Section 851.91, individuals confirmed as factually innocent after an arrest or detention may ask for record sealing or expungement. Once the petition is filed, the court sends a copy to the arresting agency and the prosecutor at least 15 days before the hearing. Form CR-409-INFO provides detailed information and procedures. Eligibility for expungement often requires that no charges were filed, charges were dismissed, or a “not guilty” verdict was entered. In some cases, an immediate arrest record sealing from the DOJ may occur under California Penal Code Section 851.93, making an additional court petition unnecessary.
For juvenile records, a Request to Seal Juvenile Records (Form JV-595) can be filed with the Contra Costa County probation department. Form JV-595-INFO provides helpful guidance. If a request to seal or expunge an arrest record is approved, the individual can legally state they have no arrest record. Public access to the record is then restricted, though criminal justice agencies and other authorized persons may still retrieve it. The California Judicial Branch’s “Clean Your Record” page offers assistance for expunging arrest records or convictions in Contra Costa County. It is important to note the distinction: sealing an arrest record hides it from public view, while expungement in California primarily means a dismissal. Even with expungement, some parties may still access the record or conviction. Eligible defendants can petition the Contra Costa County Superior Court to seal the conviction.
Contra Costa County Detention Facilities and Inmate Information
The Contra Costa County Office of the Sheriff manages the adult detention system, operating three facilities: the Martinez Detention Facility, the West County Detention Facility, and the Marsh Creek Detention Facility. The Martinez Detention Facility serves as the primary intake site for all arrestees in the county. For individuals seeking information about current inmates, the Sheriff’s Office provides an online In-Custody Locator. This official search tool helps locate incarcerated individuals in the county’s detention facilities. It offers details like names, booking dates and numbers, charges, jail locations, and custody statuses. To use the locator, one needs the inmate’s full name or booking number. The system reflects recent bookings and releases but may have delays during busy intake times.
Offline assistance for inmate information is available 24 hours a day from the Custody Services Bureau by calling (925) 646-4496. This number connects to staff who handle in-custody information for all Contra Costa County detention facilities. The Martinez Detention Facility is located at 901 Court Street, Martinez, CA 94553, and its main line is (925) 335-4600.

Frequently Asked Questions About Contra Costa Arrest Records
People often have specific questions about Contra Costa arrest records, from how long they remain accessible to the impact they have on daily life. These questions cover common scenarios and legal considerations.
How long do Contra Costa arrest records remain publicly visible?
Contra Costa arrest records remain publicly visible indefinitely unless a court orders them sealed or expunged. The record of an arrest, even without a conviction, becomes a permanent part of an individual’s criminal history. This means that without legal intervention, information about an arrest can be accessed by the public for many years. Agencies like the California Department of Justice keep these records for a long time, sometimes until a person reaches 100 years of age. This long retention period highlights the importance of understanding the legal options available to remove or restrict access to these records if eligible. It also means that a simple arrest, even without charges or conviction, can appear on background checks.
Can Contra Costa arrest records affect employment or housing?
Yes, Contra Costa arrest records can affect opportunities for employment and housing, even if there was no conviction. Many employers and landlords conduct background checks that may reveal arrest history. While federal laws like the Fair Credit Reporting Act (FCRA) place restrictions on how certain older arrest information can be used by consumer reporting agencies, direct inquiries by employers or landlords might still uncover these details. The presence of an arrest record, regardless of the outcome, can sometimes lead to negative assumptions or concerns for those reviewing applications. California law also has specific rules about when employers can consider arrest records that did not lead to a conviction. It is important for individuals with arrest records to be aware of these potential impacts and to explore legal options for record relief when possible.
What is the difference between sealing and expunging an arrest record in Contra Costa County?
In Contra Costa County, sealing an arrest record and expunging it have different effects. Sealing an arrest record typically means the record is hidden from public view. This allows the individual to legally state that the arrest did not happen in most situations. Criminal justice agencies, however, may still be able to see sealed records for certain purposes. Expungement in California, especially for convictions, is more accurately described as a dismissal. While it can relieve some legal consequences, it does not always completely erase the record. The conviction or arrest may still appear on some background checks, and criminal justice agencies can still see the information. For arrests where a person is found factually innocent, California Penal Code Section 851.91 allows for sealing. The California Judicial Branch provides resources to help people understand these differences and pursue the correct legal process for their situation.
Are juvenile arrest records public in Contra Costa County?
No, juvenile arrest records are generally not public in Contra Costa County. California law provides strong protections for the privacy of juvenile records. Information about juvenile arrests and court proceedings is typically kept confidential to support the rehabilitation of minors. Access to these records is highly restricted, usually limited to the juvenile, their parents or guardians, legal counsel, and certain court or law enforcement personnel. The intent is to prevent a juvenile’s mistakes from negatively affecting their adult life. However, there are specific circumstances where juvenile records might be shared, such as with other law enforcement agencies or courts for subsequent offenses. Minors, or their representatives, can also petition the court to seal juvenile records using forms like Request to Seal Juvenile Records (Form JV-595), further limiting access.
Can I search for recent arrests in specific Contra Costa County cities like Richmond or Concord?
Yes, you can search for recent arrests in specific Contra Costa County cities, including Richmond or Concord, by contacting the local police departments directly or checking the Contra Costa County Sheriff’s online tools. Many city police departments maintain their own records divisions that handle requests for arrest information. For example, the Antioch City Police Department provides contact information for its records bureau. The Contra Costa County Sheriff’s Office also offers an “Arrest Information” or “Arrest Log” feature on its Public Records Portal. This log summarizes recent arrest incidents investigated by the Sheriff’s Office, which covers unincorporated areas and some contract cities. These online logs are typically updated regularly but may only show information for a limited time, usually around 30 days. For the most up-to-date information for a specific city, contacting that city’s police department records division is often the most direct method.
What should I do if I find an error on my Contra Costa arrest record?
If you find an error on your Contra Costa arrest record, it is important to take steps to correct it. First, gather all documentation that supports your claim of inaccuracy. This might include court dismissal papers, proof of identity, or other official documents. Next, contact the specific agency that maintains the record where the error exists. For local arrest records, this would be the Contra Costa County Sheriff’s Office or the relevant city police department. For statewide criminal history information, you would contact the California Department of Justice. The DOJ has a formal process for challenging inaccuracies, requiring you to complete a “Claim of Alleged Inaccuracy or Incompleteness” form (BCIA 8706) and provide supporting proof. Timely correction of errors on your record is important because inaccurate information can cause problems with employment, housing, or other legal matters.
