San Dimas Jail Inmate Search

If you think you may have a warrant in Los Angeles County or elsewhere in California, or you need information about a court case involving you, a friend, or a family member, start with the California Superior Court.

Most people charged with a crime in Los Angeles County, and anywhere in California, have a constitutional right to be released on bail before trial, though there are exceptions for certain capital and violent felony cases. According to the California Supreme Court, judges must consider a defendant’s ability to pay, and can hold someone who can’t afford bail only if no less restrictive condition would protect public safety or ensure their return to court. Under Rule 4.101, judges also cannot consider whether a defendant has asked for a jury trial.

Find out an inmate’s bail by calling the San Dimas Jail at 909-599-1261. If you know the charge, you can also look up the standard amount on the Los Angeles County bail schedule. Cash, surety bonds, and property bonds are all accepted.

The San Dimas Jail’s license covers 25 inmates, but the jail often has to make room for many more, especially on weekends. Most city and county jails in California experience a monthly turnover of at least 35-40%, another 25-30% every 90 days, and another 15-20% every six months, with about 8-9% of inmates staying six to twelve months. Those who stay longer than a year usually face serious charges such as rape or murder. Because those cases take longer to prepare for trial, offenders arrested in this county remain in one of the Los Angeles County facilities much longer.

Every year, Los Angeles County law enforcement agencies arrest and detain approximately 462,420 offenders.
