California limits criminal loitering to specific contexts, while San Bernardino County enforces trespass rules on county property, parks after closing, and unincorporated commercial centers.
Under California Penal Code section 647, loitering itself is not a crime, but loitering with intent to commit prostitution-related offenses or to delay or obstruct business may be charged. Trespass under Penal Code section 602 covers refusing to leave property after warning by an owner or peace officer. San Bernardino County regional parks close at posted hours, and county facilities require visitors to remain on official business. The Sheriff also enforces commercial center no-trespass letters allowing officers to act on behalf of merchants.
Trespass after warning, lingering past park curfew, or interfering with business can trigger misdemeanor charges and bans from the property.
