Full Breakdown
Alameda County Code Chapter 6.12 splits public drinking into two prohibitions: Section 6.12.020 bars drinking on any public street, highway, alley or sidewalk outright, while Section 6.12.010 bars drinking on customer or employee parking lots within five hundred feet of a public way unless the property owner allows it. Both rules apply only in unincorporated communities such as Castro Valley and San Lorenzo. Oakland, Berkeley and the county's other cities enforce their own open-container ordinances.
Violations & Fines
Violating either drinking prohibition in Chapter 6.12 is an infraction carrying a fine of up to one hundred dollars, in addition to any other penalty the law allows, per § 6.12.090.
