Sun Prairie's Curfew Laws: The Rules That Matter

Every city handles curfew laws a little differently. In Sun Prairie, Wisconsin, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Juvenile Curfew

City of Sun Prairie law bars anyone under seventeen from public streets, parks, school grounds, and other public places between 10 p.m. and 5 a.m. Sunday through Thursday nights, and from midnight to 5 a.m. on Friday and Saturday nights. Parents, guardians, and business owners share responsibility for keeping minors off the streets during those hours.

Key details: Curfew age: Under 17. Weeknight hours: 10 p.m.-5 a.m. Sun-Thu. Weekend hours: Midnight-5 a.m. Fri-Sat. Minor penalty: $1-$25 forfeiture plus costs. Parent warning: Required before first penalty.

A minor convicted of violating the curfew forfeits not less than one dollar and not more than twenty-five dollars, plus the cost of prosecution. A parent, guardian, or custodian who has already received one warning and later allows a violation is subject to the general forfeiture penalty under § 1.24.010, and a second violation within six months can result in the child being referred to the juvenile court under Wisconsin Statutes Chapter 48.

This is not one of those rules that cities tend to ignore. Sun Prairie actively enforces its juvenile curfew requirements.

Park Curfew

Every city park in Sun Prairie closes at 10 p.m. and reopens at 6 a.m., with a handful of carved-out exceptions for softball games running late, permitted evening setups, and two pickleball complexes with their own separate hours.

Key details: Standard park hours: 10 p.m. to 6 a.m.. Softball game cutoff: 10:20 p.m., no new innings after. Haven Park Pickleball hours: Closed 9 p.m. to 7 a.m.. Wyndham Hills Pickleball hours: Closed 10 p.m. to 5 a.m.. After-hours use: Requires parks department permit.

Chapter 12.44 sets no dedicated fine for being in a closed park after hours, so a violation of § 12.44.050 is enforced under the city's general penalty, § 1.24.010, a forfeiture of $5 to $500 for a first offense and $20 to $1,000 for a repeat offense within a year, plus costs of prosecution.

The Bottom Line

Sun Prairie's curfew laws rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Sun Prairie is broadly strict or permissive.
