San Francisco, CA Public Conduct: Public Alcohol Use (2026)

Police Code Section 21 does not measure how much you drink; it bans consuming any alcoholic beverage in any quantity, so a single sip on the sidewalk violates the section as fully as an emptied bottle. The prohibition covers every public street, avenue, sidewalk, stairway, alley, and thoroughfare within the City and County of San Francisco, and it also reaches onto private property in a narrow band: spots within 15 feet of a public way that are open to public view, where the drinker lacks the owner's permission.

That second prong is reflected in the section's own title, which covers both public streets and public property open to public view. The exceptions all trace back to a lawful setting for the drink. Private dwellings are outside the ban, as is prescribed medication. 2 tables-and-chairs permit, Shared Spaces permits paired with an ABC license, and Entertainment Zone events. The pattern is consistent: where San Francisco has itself permitted outdoor drinking through a parade permit, a parklet, Shared Spaces, or an Entertainment Zone, Section 21 stands down, and everywhere else on the public way it applies.
