Alameda County Arrest Records

Alameda County arrest records are created and maintained by the local police departments or the arresting agency. Records may also be maintained by the California Department of Justice. Per the California Penal Code, law enforcement officers in Alameda County have the right to arrest individuals suspected of committing criminal offenses, including misdemeanors and felonies. These records are typically managed by local law enforcement agencies but may become a part of Alameda County Court Records if the arrest leads to a judicial proceeding.

Upon arrest, the individuals undergo a process called “booking,” which involves documenting a suspect’s personal information, fingerprints, details, and reason for the arrest. This results in the creation of an arrest record. Depending on the severity of the case, the suspect may be transferred to a detention facility before trial. The outcome of the trial determines whether the arrestee is released or not.

Yes. Alameda arrest records are public records. As such, interested parties can request arrest records from any law enforcement agency in Alameda County. However, the California Government Code may exempt some arrest records from public disclosure. They include:

  • Information that would prevent the successful completion of the investigation or any other related investigation

  • Criminal offender record information
  • Identifying juvenile information

Per the California Penal Code 13300, access to criminal records is restricted to only the subject of the records, parties with the subject’s consent, and authorized agencies(law enforcement agencies and certain employers).

Eligible parties can visit the sheriff’s office to get criminal records in Alameda County. Written requests can also be submitted via mail or on the sheriff's website.

Alameda County Arrest Records Vs. Criminal Records

Although “arrest records” and “criminal records” are often used interchangeably, they have different meanings.

Alameda arrest records are created and maintained by the sheriff’s office and other police departments. They contain details of a suspect/arrestee’s personal information, charges or reasons for arrest, events leading up to the incident, and the arresting officer. Arrest records may include the outcome of the arrest. However, they do not include the details of court hearings or other criminal information.

On the other hand, Alameda's criminal records contain details of a subject’s journey within the criminal justice system, including mugshots, arrests, pending warrants, fingerprints, and court convictions. It also provides details of the subject’s personal history, including place of birth and education. Contributions from law enforcement agencies, court systems, and correctional facilities create criminal records. The California Department of Justice is shouldered with the grand responsibility of maintaining Alameda criminal records.

How Long Do Arrests Stay on Your Record?

Indefinitely. There is no set time in California for erasing details of an arrest from a subject’s record. Generally, the California Department of Justice retains a record until the subject turns 100 years old. An individual who wishes to erase an arrest from one’s record may opt for an expungement or sealing.

  • Petition for early termination of probation in line with California Penal Code. This applies to individuals on probation who have paid their fines and turned a new leaf.

An arrest warrant is an official precept signed by a judge or magistrate which authorizes a peace officer to arrest and detain an individual. Arrest warrants are often issued before arrests are made. However, the California Penal Code 836 permits a peace officer to arrest an individual without a warrant if there is probable cause to believe that the person committed a public offense or if such offense was committed in the officer's presence.
