Brentwood, CA Curfew Laws: Park Curfew (2026)

Brentwood Municipal Code Chapter 12.08 governs parks and recreation facilities. All city parks, trails, sports complexes, and open-space areas are closed to the public from 10 PM to 6 AM daily unless otherwise posted at the entrance or authorized under a special event or facility-use permit. Entering or remaining in a closed park constitutes an infraction under Chapter 1.08 administrative citations, with fines starting at 100 dollars for a first offense and escalating for repeat violations. Some facilities (such as the Brentwood Family Aquatic Complex or lit sports fields like Creekside Park and Sunset Park) have posted operating hours that close earlier than 10 PM, and those posted hours control. Brentwood Police and Parks Maintenance staff patrol parks at closing and may issue citations or pursue trespass charges under California Penal Code 602 for persistent violators. Overnight camping, loitering, and sleeping in parks are prohibited regardless of the hour, though the city coordinates with Contra Costa County Health Services on outreach for unhoused individuals rather than cite-and-release. Sunset-scheduled activities (youth soccer tournaments, community movies in the park) require a Facility Use Permit from the Parks and Recreation Department, which can authorize use beyond 10 PM for specified evenings. Dogs must be off trails and park grounds by closing and leashed at all times per the animals chapter. Parking lots close with the parks, and vehicles left overnight can be cited or towed.
