Understanding the Three-Tier System in Allegan County

Michigan classifies every registered sex offender into one of three tiers. The classification is set by the Michigan State Police at the time of registration and is based on the offense of conviction. Under MCL 28.725a, Tier I includes lower-level offenses such as fourth-degree criminal sexual conduct under MCL 750.520e. Tier I registrants verify their information once per year and remain on the public registry for 15 years.

Tier II covers more serious crimes, including second-degree criminal sexual conduct under MCL 750.520c. These registrants must verify every six months and stay on the list for 25 years. Tier III is reserved for the most serious offenses, such as first-degree criminal sexual conduct under MCL 750.520b. Tier III offenders verify every three months and are registered for life. The tier is shown on every public registry profile in Allegan County, giving residents an at-a-glance sense of how serious the underlying offense was and how often the person must check in.

Michigan has roughly 45,000 registered sex offenders statewide. Allegan County's share reflects its mid-size population. The county has a mix of all three tier levels on its registry, from lower-risk Tier I registrants to lifetime Tier III offenders.
