Contrary to popular belief, it is technically illegal to possess an open container of alcohol in public within Key West city limits, according to Municipal Code § 18-87. While many tourists assume it is like New Orleans or Savannah, the law prohibits walking down the street with a drink. However, there is a local tradition of "practical enforcement": police often issue a verbal or written warning to first-time offenders provided they immediately dispose of the drink. On high-traffic areas like Duval Street, officers may "look the other way" unless a person is being rowdy or causing a disturbance. In 2026, the city remains strict about open containers in parked or moving vehicles. To be safe, if you are leaving a bar, finish your drink inside or ask for a "to-go" cup only if you plan to walk onto private property, as the fine for a second violation can be significant.
