Curfew Laws in Fairfield, CA

If you live in Fairfield or are thinking about moving there, curfew laws are one of those things you probably won't think about until they affect you directly. Fairfield has 2 specific rules on the books covering different aspects of curfew laws, and some of them might surprise you.

Juvenile Curfew

Fairfield bans minors under 18 from public places from 11 p.m. to 5 a.m. every night, and from 8:30 a.m. to 1:30 p.m. on school days if they should be in class. Both curfews are infractions, and a parent who allows the violation is guilty too.

Key details: Nighttime curfew: 11:00 p.m. to 5:00 a.m. daily. Daytime curfew: 8:30 a.m. to 1:30 p.m. on school days. Applies to: Persons under 18. Penalty class: Infraction, each violation separate. Exceptions: 10 listed, incl. work, emergencies, First Amendment.

A minor caught in public during curfew hours without a valid exception is cited for an infraction, as is a parent or guardian who knowingly lets that happen. Officers first ask age and reason for presence before deciding whether to cite; supervisors do not need to prove intent, only presence during the restricted window without an applicable defense.

This is one of the stricter rules in Fairfield's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Park Curfew

Fairfield closes every public park and open space area 30 minutes after sunset and reopens them at sunrise under Municipal Code § 12B.11, and anyone who stays past curfew without the Director's or a Park Ranger's approval can be ejected. One Lake Park runs on its own fixed hours of 4:00 a.m. to 10:00 p.m.

Key details: Governing law: Fairfield Municipal Code § 12B.11. Curfew hours: 30 minutes after sunset to sunrise. One Lake Park hours: 4:00 a.m. to 10:00 p.m. (§12B.7(b)(1)). Exception: City-sponsored activities are excepted. Enforcement: Park Ranger may eject violators (§12B.17).

Staying in a Fairfield park or open space area after curfew violates Section 12B.11. Park Rangers, the Landscape Maintenance Manager, or designated City staff can eject a violator on the spot under Section 12B.17, and confiscate any property used in the violation. Because Chapter 12B carries no specific fine, a citation falls back to the citywide general penalty in Section 1.7: up to a $100 infraction for a first offense.

The Bottom Line

Fairfield'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 Fairfield is broadly strict or permissive.
