Registered Sex Offenders

In order to maintain awareness of sex offenders living in your neighborhood, we have added a Sex Offender Registry to our website. The registry will allow you to enter any local address. It will then provide a list of all registered Contra Costa County sex offenders living within a one-mile radius of the boundaries of unincorporated Contra Costa County, subject to full address disclosure. 

If you have questions or concerns about offenders not listed on this website, please visit the Megan's Law website or call (925) 313-2611. If you are looking for information about a particular sex offender registered in Contra Costa County, the registry can help there as well.

We encourage you to take advantage of the free email notification. When a sex offender registers with the Contra Costa County Office of the Sheriff you will be alerted if the offender’s address is:

  • In Contra Costa County
  • Within one mile of the address you have entered on your subscription
