Sex Offender Registry


In order to maintain awareness of sex offenders living in your neighborhood, we have added a Sex Offender Registry Search to our website. Once you enter any local address, it will provide a list of all registered Ontario County sex offenders living within a 1-mile radius of the registered address(es) that fall within the boundaries of Ontario County. If you are looking for information about a particular sex offender registered in Ontario County, the registry can help there as well.

Email Notification


We encourage you to take advantage of the free email notification. When a sex offender registers with the Ontario County Sheriff’s Office you will be alerted via email if the offender’s address is within Ontario County and within 1 mile of the address you have entered on your subscription.
