Rancho Cucamonga, CA Public Conduct: Public Alcohol Use (2026)

020 makes it unlawful to consume any alcoholic beverage while on a public street, alley, way, sidewalk, or parkway anywhere in the city, and the section expressly covers drinking inside a motor vehicle as well as in the open. 010, so beer, wine, and distilled spirits are all covered the same way. The prohibition is written broadly to reach the full public right-of-way rather than only sidewalks, meaning an open container being consumed on a parkway strip between the sidewalk and curb, or in a stopped car on a public street, falls within the ban just as much as drinking while walking.

030 sets the penalty: a misdemeanor conviction can bring a fine of up to $1,000, imprisonment of up to six months, or both. Because the ordinance is framed around consuming, not merely possessing, an open container, a sealed beverage carried through a public street is not itself a violation of this chapter, though other state open-container and DUI laws can still apply separately to a vehicle occupant. The chapter does not carve out an exception for special events, so drinking alcohol on a public street during a city-permitted parade, festival, or block party still requires separate authorization through an alcohol permit tied to the event rather than through this chapter.
