Penal Code Section 290 requires sex offenders to register their residency with local law enforcement agencies. In addition, sex offenders who are on parole or probation with the state or county are subject to further restrictions and conditions, including residency restrictions and GPS monitoring as determined on a case-by-case basis. In making case-by-case determinations, state law currently implements a “Containment Model” approach to sex offender management. The Containment Model involves collaboration among a team of professionals and the use of research-based, state-authorized risk assessment tools to evaluate the risk of sexual re-offense and assist in developing appropriate individualized parole or probation conditions. These practices may change subject to changes in state or local law. (Ord. 3411 § 1, 2017; Ord. 3034, 2006).
