National City, CA Public Conduct: Public Alcohol Use (2026)

Chapter 10.30 of the National City Municipal Code, Regulation of Alcoholic Beverages in Public Venues and Places, states its purpose in section 10.30.010: the City Council regulates consumption, use or possession of alcoholic beverages and open containers in areas that the Business and Professions Code and Vehicle Code do not expressly regulate. Section 10.30.020 defines an open alcoholic beverage container as any can, bottle or other receptacle containing an alcoholic beverage that has been opened, whose seal has been broken or removed, or whose contents have been partially removed.

Section 10.30.050 is the general rule. No one can consume any alcoholic beverage or possess an open container on any public street, sidewalk, alley, plaza, public parking lot, private parking lot open to the public or any undeveloped area within the city limits without a permit duly issued by the city manager. Section 10.30.030 adds a park rule: it is unlawful in any city park or adjacent city-owned public place to consume alcohol or possess an open container. The city manager posts signs at each pedestrian and vehicle entrance of a park, but installation of signage is not a prerequisite to enforcement or prosecution. Section 10.30.040 lets the City Council allow sale or use in a city-owned building within a park through a temporary use permit under Chapter 15.60, and buildings operated or leased by a third party under a written agreement approved by the council follow that agreement.

Section 10.30.060 reaches vehicles that are not on a highway. It is unlawful to consume alcohol or possess an open container inside such a vehicle, on private property with public access, public parking lots, private parking lots open to the public or undeveloped areas. A container securely locked in a car trunk or locked exterior compartment is exempt.

Section 10.30.070 puts a duty on licensed sellers: each exterior wall facing a parking lot needs a WARNING sign at least eighteen inches wide and twenty-four inches high, with black lettering at least one inch high on white, one sign per fifty-foot portion of wall, its bottom at least five feet above the pavement. Section 10.23.040 separately bars consuming alcohol or possessing an open container on a public transportation vehicle.
