Sex Offender Unit

The RSONU (Regional Sex Offender Notification Unit) was formed in 1998.  At that time Washoe County, the City of Sparks and the City of Reno all agreed there was a need for coordination in law enforcement in the tracking, monitoring, investigation, public notification, and the arrest and prosecution of non-compliant sex offenders.  The RSONU operates as a regional, multi-jurisdictional and collaborative entity to carry out the requirements of community notifications as set forth in Chapter 179D of the Nevada Revised Statutes.  The RSONU’s jurisdictional boundaries encompass all of Washoe County, including the Cities of Reno and Sparks.

In addition to the Washoe County Sheriff’s Office investigator, investigators from RPD and SPD are sworn in as Deputies with the WCSO in order to carry out the mission of the Unit. The WCSO also provides an Administrative Office Support Specialist to help with clerical functions. 

The RSONU is open Monday through Friday, 7am to 5pm, excluding holidays, and can be reached at 775-353-2244. Day to day operations are conducted out of the Sparks Police Department.

Currently, there are about 1,300 registered sex offenders in the Reno, Sparks and Washoe County area.  Each of the three investigators are assigned over 400 offenders to monitor.
